Introduction

Нації вмирають не від інфаркту. Спочатку їм відбирає мову.
Ліна Костенко

Nations don’t die from heart attacks. They go mute first.¹
(Lina Kostenko, Ukrainian poetess)

evals are surprisingly often all you need
(Greg Brockman, OpenAI President)²

The Ukrainian language is not at risk of dying, and as of 2023, this much is certain. But before 2014, the quote above was so incisive it hurt.

The last 10 years have led to a resurgence of Ukrainian language, especially its use in informal and non-academic contexts. This was followed by an increase of resources dedicated to its study and use.

On a 2020 survey³ on linguistic diversity in NLP, the Ukrainian language was classed under “rising stars”: languages with a thriving community online but let down by insufficent labeled data.

This Thesis introduces the first Ukrainian-language LM benchmark, and as part of it introduces a number of novel labeled datasets.

Historical context and bilingualism in the modern Ukrainian language

L’Ukraine a toujours aspiré à être libre
“Ukraine has always aspired to be free.” Voltaire, 1731 ⁴

A significant number of people in Ukraine are bilingual (Ukrainian and Russian languages), and most Ukrainians can understand both Russian and Ukrainian ⁵.
The reasons for this include Ukraine’s geographical and cultural proximity to Russia, as well as of consistent policy first of the Russian empire and the Soviet Union.

This section sketches the history of the language, describes the bilingual nature of Ukraine’s society and the impact of historical state policies on its modern development.

Intro (TODO better title)

The Ukrainian language belongs to the Slavic family of the Indo-European languages (which also contains languages such as Polish, Czech, Serbian, Bulgarian), specifically to the East Slavic branch, which contains Belarusian, Russian, and Ukrainian⁸. Towards the end of the X century the East Slavonic group of diealects was relatively uniform, with the differences separating Ukrainian, Russian and Belarusian appearing since then, as the result of linguistic and political processes. ⁹

While all three are mutually intelligible to a certain extent, Ukrainian has more in common with Belarusian than with Russian ⁹; outside the branch, Ukrainian has partial intelligibility with Polish¹⁰.

This stems from the fact that in the 15th century, parts of what is now Ukraine and Belarus were part of the Polish-Lithuanian commonwealth, with Polish becoming the lingua franca of Ukrainian-Belarusian lands.

As a result, a large proportion of the Ukrainian lexicon consists of borrowings from the Polish language, and vocabulary remains the component of the language where the difference with Russian is most immediately noticeable. ⁹

The suppression of Ukrainian in the Russian Empire

In the Russian Empire, the broader imperial ideology sought to assimilate various ethnicities into a single Russian identity (with Russian as dominant language), and policies aimed at diminshing Ukrainian national self-consciousness were a facet of that.¹¹

Ukrainian (then officially called little Russian ⁹ and officially a dialect) was¹² stigmatized as a strange dialect of Russian, with its literature not taken seriously; the general attitude being that Ukrainians needed to be “civilized” by Russia, by its language and developed culture.¹¹

Attempts to extinguish a separate Ukrainian identity weren’t limited by stigmatization — the history of Ukrainian language bans is long enough to merit a separate Wikipedia page with the list, ¹³ with the more notable ones in the Russian Empire being the 1863 Valuev Circular (forbidding the use of Ukrainian in religious and educational printed literature)¹⁴¹⁵ and the Ems Ukaz, a decree by Emperor Alexander II banning the use of the Ukrainian language in print (except for reprinting old documents), forbidding the import of Ukrainian publications and the staging of plays or lectures in Ukrainian (1876)¹⁶.

The convergence of Ukrainian and Russian in the Soviet Union

The first decade of Soviet Union brought Ukrainisation as part of a new Soviet nationalities policy, leading to a short-lived period of flourishing for Ukrainian literature and culture in general.¹⁷

Many of the Ukrainian writers and intellectuals of that period became later known as “the executed Renaissance”¹⁸: most¹⁹ of them were purged in the years to follow⁷, after the Soviet Union took a sharp turn towards Russification in the late 1920s and in the multiple waves of purges afterwards.

Those purged included many of the members of the committee that in 1928 created the first unified Ukrainian spelling rules.²⁰

A new ‘orthographic’ reform was drafted in 1933, without public discussion this time ¹⁷. It had the stated goal of removing alleged “burgeoise nationalist” and “pro-Polish” influences in the previous one, especially by the withdrawal of “artificial barriers” between the Ukrainian and Russian languages²⁰. In practice, bringing the Ukrainian language closer to Russian in many ways, from banning the (absent in Russian) letter ґ to introducing changes to grammatical forms ²⁰, adding near absolute reliance on Russian when spelling loanwords and changing the gender of many of them to match Russian, and by making an effort to reduce Ukrainian-specific vocabulary¹⁷, especially scientific terminology.

The role of Russian in Soviet society was openly declared to be not just the language of all Soviet peoples, but also the source language for the enrichment of the other languages in the Soviet Union.⁹

• TODO find some place to fit this:
  • One interesting aspect is the asymmetry in language intelligibility: Ukrainians are “clearly more successful” in understanding Russians than vice versa ¹⁰. If this mutual understanding was only the result of the closeness of the two languages, there would be no such asymmetry.

Towards the end of the Soviet Era, “it is possible to speak of diglossia in Ukraine, with Russian as the High variety used in formal, administrative, and educational domains, and Ukrainian is less formal, home settings.” ⁸

After the fall of the Soviet Union, there were many proposals for restoring the original orthography, but only the letter ґ was restored. In 2019 a new version of the Ukrainian orthography was approved, which restored some of the original rules as ’legal’ variants but without mandating any of them.

The contemporary Ukrainian linguistic landscape

Around 2012, I stumbled upon a forum thread with the topic “I’m moving to Ukraine, which language should I learn, Ukrainian or Russian?”. One answer was “It doesn’t really matter, and if someone will care too much about which language you speak, they are not the people you want to speak to anyway” — not an uncommon sentiment at the time.

For most Ukrainians, the language spoken was/is just not part of one’s self-identification as Ukrainian. Among those surveyed across Ukraine in 2012-2017, only 2.7-4.9% considered the language spoken what determines their nationality (among those who considered themselves Ukrainian it was 1.8-2.5%, Russian — 8.8-15.9%) ⁵.

It is typical to speak e.g. Russian at school and Ukrainian at home ²¹, or different languages with different family members (for example, my entire life I spoke Ukrainian with my father and Russian with my mother).

Conversations where different people use Russian or Ukrainian (without any effort awkwardness or negative effects) were (and are) normal as well. This is illustrated by a 2017 survey²² of 2,007 respondents across Ukraine. It found that in the presence of a Ukrainian speaker, 17% of people will speak Russian and ~18% both Russian and Ukrainian (in the other case, ~29% will speak Ukrainian and ~23% both Russian and Ukrainian).

Just as typical is code-switching — changing the language or dialect spoken within the same conversation, sometimes within the same sentence ²³. The Parliamentary Code-Switching Corpus paper²³ shows examples of this happening for different reasons, such as: inserting quotes/idioms in Russian, using Ukrainian legalese/cliches or law names, switching the language for stylistic purposes (e.g. distinguishing between the official Ukrainian position and a personal one), triggered code-switching (switching the language after using a word or name in the other language), inserting individual words in the other language or just heavily mixing both without clear motivation.

The latter is related to Surzhyk, mixed Russian-Ukrainian speech (variously defined as “a hybrid language that involves Russian and Ukrainian in its creation”²⁴ or “a pejorative collective label for non-standard language varieties”²⁵)[^45], widely spoken (and more rarely written) across Ukraine, especially its eastern, southern and central parts²⁴.

The Russian attack on Crimea in 2014 for many led to stronger attachment to Ukraine and alienation from Russia, with surveys between 2012 and 2017 showing “a consistent and substantial shift”²¹ from Russian linguistic and ethnic identification towards Ukrainian⁵, and the full-scale invasion of 2022 accellerated this process, as seen in Rating Group’s March 2022 “Language Issue in Ukraine” survey²⁶.

This was also quantified by an analysis ²¹ of Ukrainian Twitter data between 13th January 2020 and 10th October 2022, reporting behavioural language changes across Russian-Ukrainian-English while controlling for user turnover (users joining or leaving Twitter).

The plot (adapted from Figure 4 of ²¹) in Figure XXX shows an increase of the use of Ukrainian over Russian (purple) starting before the full-scale invasion and sharply increasing afterwards.

Notably, of the 1,363 users tweeting predominantly (>80%) in Russian before the outbreak of the war, 61% tweeted in Ukrainian more after the outbreak, and ~25% (341) started tweeting predominantly (>80%) in Ukrainian (hard-switch from Russian to Ukrainian). There were only 3% hard-switches from UA to RU in that period.

Ukrainian Twitter users are not a representative sample of the Ukrainian population for several reasons, but the study is likely indicative of wider societal trends.

The authors interpret the switch as users’ conscious choice towards a more Ukrainian identity.²⁷

TODO fit the below somewhere:

• Many Ukrainians started critically reevaluating their language use patterns. (For example, I learned that two friends spoke Ukrainian at home but Russian at school not because they spoke Russian, but because of (basically) peer pressure.)
• mention the diglossia towards the end of USSR

With more people switching to Ukrainian partially or full-time, for different reasons, the importance of Ukrainian NLP grows correspondingly.

Ukrainian as a mid-resource language?

In the taxomy of languages based on data availability ³ (see below), Ukrainian is classified in class 3, “the rising stars”: languages with a thriving online cultural community that got an energy boost from unsupervised pre-training, but let down by insufficient efforts in labeled data collection. Sample languages from that group include Indonesian, Cebuano, Afrikaans, Hebrew. (Russian is in class 4, English and German are in class 5.)

³ as quoted in Why You Should Do NLP Beyond English

From a different angle, looking at estimates of languages used on the Internet (as estimated percentages of the top 10M websites), as of October 2023 Ukrainian is at number 19 (0.6%), between Arabic and Greek²⁸²⁹. English is #1 (53.0%), Russian #3 (4.6%), German at #4 (4.6% as well).

Ukrainian Wikipedia is 15th by daily views and by number of articles³⁰.

The importance of NLP for mid- and low-resource languages

The Bender rule and language independence

Emily M. Bender in 2011³¹ formulated what would come to be known as the Bender rule³²: “Name the languages we study”.

Her original 2011 paper — written in the pre-LLM era — discusses the problem of language independence, that is the extent to which NLP research/technology can scale over multiple (or ‘all’) languages. In her more recent writing on the topic, she notes how work on languages other than English is often considered “language specific” and thus viewed as less important ³², and the underlying misconception that English is a sufficiently representative language and therefore work on English is not language specific.

A NLP system that works for English is not guaranteed to behave similarly for other languages, unless explicitly designed and tested for that. Or in different words, “English is Neither Synonymous with Nor Representative of Natural Language”. ³²

She highlights 8 proprieties of English that highlight it’s shortcomings in representing all languages, of them 4 apply to Ukrainian: little inflectional morphology, fixed word order, possible matches to database field names or ontology entries, and massive amounts of training data available.

In the context of this thesis, an interesting facet of this issue was my intuitive assumption that Python’s sort() would sort the letters in their alphabetical order — which is what it does in English — which, for Ukrainian, it didn’t. In hindsight absolutely unsurprising, but I find it absolutely fascinating that for many English-only-speakers many things just work, like python’s sort() doing the intuitively correct thing, and this is taken for granted (along with the assumption that it works for other languages just as well, and that results and approaches generalize). Having for the first time sorted Ukrainian letters in Python I realize how all-encompassing such world models can be. (For details about the sorting issue, see subsection XXX about the LMentry-static-UA task.)

Roadmap

This master thesis tackles the following problems in the context of Ukrainian language:

• Research the current state of NLP, especially focusing on the availability and quality of:
  • datasets
  • corpora
  • tools
  • literature
• Create novel Ukrainian-language datasets usable as benchmark tasks:
  • create human baselines where practicable
  • make them publicly available through established platforms
• Create a benchmark for the evaluation of LMs, using both the newly-created datasets/tasks and pre-existing ones
• Evaluate the existing Ukrainian LMs on this benchmark

Additional research questions are:

• Evaluate whether cross/multi language models that include Ukrainian perform equally well to Ukrainian monolingual models
• Research whether there’s a significant difference in scores of tasks translated to Ukrainian using automated methods as opposed to human translations
• Compare the extent to which the language matters when solving problems, with the following languages:
  • Ukrainian
  • English (high resource language)
  • Russian (high resource language from the same language family as Ukrainian)

Ukrainian language

Grammatical notation and abbreviations

Glossing notation

Throughout this section, a notation system loosely based on the Leipzig Glossing Rules³⁴ (LGR) for interlinear glossing will be used in examples showcasing Ukrainian language phenomena and translations to English and occasionally German.

Interlinear glosses will not be interlinear, but each gloss will be a superscript to the word it refers to.

For each word, it will be formatted thus:

• The translation will be separated with the grammatical morphemes relating to it by hyphens (-)
• The translation to English will be written in lower case
• The grammatical morphemes will be upper-case abbreviations separated by dots (LGR rule 3).

Not all words of the example will be annotated, only the ones relevant to the example being made. Words already in English will not be translated.

Each translation will be provided on a separate line, with the language marked as ISO 639-3 code: eng for English, ukr for Ukrainian, deu for German, rus for Russian.

For example:

eng: the man^NOM.SG saw^PST the dog^NOM.SG
ukr: чоловік^man-NOM.SG побачив^{saw-PST.MASC.SG} собакy^dog-ACC.SG

In the cases where glosses on morpheme level are needed, the (relevant) segmentable morphemes in the word will be separated by hyphens, and each will have its gloss in its superscript³⁵. The absence of a morpheme needing a corresponding gloss will be marked as $\varnothing$ (LGR Rule 6).

ukr: 5 собак^dog-$\varnothing$^GEN.PL

Ungrammaticality (examples of grammatically incorrect language) will be denoted by a single asterisk (*) preceding the sentence or the specific word:

ukr: мій *друзь

Ukrainian from a linguistic perspective

Alphabet

• TODO remove this subsection and move the problems paragraph somewhere else.

The Ukrainian alphabet is written in Cyrillic and has 33 letters, in writing the apostrophe and hyphen are also used. It differs from Russian by the absence of the letters ё, ъ, ы and э, and the presence of ґ, є, і, and ї.

This helps (but doesn’t completely solve the problem of) differentiating the two languages, which is needed relatively often: Russian-language fragments within otherwise Ukrainian text (e.g. untranslated quotes in text intended for a bilingual audience) are a typical problem, and one that needs to be solved when building reference corpora or datasets.³⁹

Grammar

Strong morphology

Ukrainian is is a synthetic⁴⁰ inflected language⁴¹, that is it can express different grammatical categories (case, number, gender, ..) as part of word formation. In other words, that information about grammatical categories tends to be encoded inside the words themselves.⁴²

(German, too, is a fusional language, but with a smaller degree of inflection. English, on the other hand, largery abandoned the inflectional case system⁴³ and is an analytic language, conveying grammatical information through word order and prepositions.)

Specifically, Ukrainian:

• nouns decline for the 7 cases⁴⁴ and 2 numbers (singular, plural)
• adjectives agree with nouns in gender, case, number
• verbs
  • conjugate for tenses, voices, persons, numbers
  • and in the past tense, they agree with gender as well
• has no articles.

Inflection for word order

The standard word order is Subject-Verb-Object (SVO), but the inflectional paradigm allows free word order. In English the SVO word order in “the man saw the dog” (vs “the dog saw the man”) determines who saw whom. In Ukrainian it’s the last letter of the object (dog) that marks it as such.

eng: the man^NOM.SG saw the dog^NOM.SG
ukr: чоловік^man-NOM.SG побачив^saw собакy^dog-ACC.SG

This allows the ordering of the words can be used for additional emphases or shades of meaning (similar to German).

A more extensive example:

eng: we found^PST a green^ADJ cup ^NOUN on the table ^ADJ
ukr: ми^we знайшли ^{found-PST.1PL} зелену ^{green-ADJ.F.SG.ACC} чашку ^cup-F.SG.ACC на^on столі ^{table-M.SG.LOC}
deu: wir^we fanden^{found-PST.1PL} eine^{a-INDEF.F.SG.ACC} grüne^{green-ADJ.F.SG.ACC} Tasse^cup-F.SG.ACC auf^on dem^{the-DEF.M.SG.DAT} Tisch^{table-M.SG.DAT}

The amount of categories conveyed by the nouns is roughly similar to German.

Inflection in verbs

Morphology in verbs works in a very similar way. Additionally, unlike other Slavic languages, Ukrainian has an inflectional future tense (formed by a suffix in the verb) in addition to the standard compound future formed by using an auxiliary word бути (“to be”). ⁴⁵ All this makes longer verbs quite common.

For example, the verb ви́користати^use-INF.PFV is in perfective aspect, therefore it’s a completed action (“use up” or “utilize completely”) or one seen as a whole even if not completed (“Tomorrow I’ll use my cane to get the pencil from under the bed”)⁴⁶. It can be transformed into використовуватимуться^{use-IPFV-FUT-3PL-REFL4748} (3rd person plural imperfect-reflexive-future) thus (in bold the changes):

• використ^use-ROOT-а^PFV-ти^INF: to use (e.g. my cane to get home tomorrow)
• використ^use-ROOT-ов-увa^IPFV-ти^INF: to use (e.g. my cane from time to time)
• використ^use-ROOT-ов-увa^IPFV-ти^INF-муть^FUT.3PL: “They will use their canes”.
• використ^use-ROOT-ов-увa^IPFV-ти^INF-муть^FUT.3PL-ся^REFL:
  • “The canes will be used tomorrow” (passive)
  • “The mice will use themselves to attract the cat into a trap” (reflexive)

Minimal equivalent sentences:

eng: they ^3PL will^FUT be^PASS used^PST.PTCP
deu: sie^they werden^will-FUT.PL verwendet^{used-PST.PTCP} werden^be-PASS
ukr: вони^they використовуватимуться^{use-IPFV-FUT-3PL-REFL}
rus: они^they будут^be-FUT.3PL использоваться^{use-INF-FUT-REFL}

Todo (This is not a contrived example, використовуватимуться is a natural word in everyday speech.)

• TODO
  • do I want this representation? correct it if yes
  • A different representation of the Ukrainian sentence:
    $\underset{\text{PRON-3PL}}{\overset{\text{they}}{\text{вони}}}$ $\underset{\text{VERB-INF}}{\overset{\text{use}}{\text{використовува-}}}$$\underset{\text{FUT}}{\overset{\text{will}}{\text{ти-}}}$$\underset{\text{VERB-3PL}}{\overset{\text{use}}{\text{му-ть-}}}$$\underset{\text{REFL}}{\overset{\text{themselves}}{\text{ся}}}$

Numerals; agreement of nouns with numerals

Ukrainian numerals can be cardinal (one), ordinal (first) and adverbial (once). They change to varying extent based on case, number⁴⁹, gender.

The inflection of nouns for (grammatical) number has two classes, singular and plural. Old East Slavic (from which Ukrainian is descended) had a third grammatical number, the dual, since lost⁵⁰. Some of its traces are in the agreement of nouns and numerals (1 dog, 4 sheep, …).

A simplified⁵¹ breakdown follows.

Numerals ending with the following numbers require nouns to:

• 1: agree in gender, number, case with the numeral
• 2, 3, 4: require some nouns to be in the nominative plural, some - nominative singular⁵²
• 5-9, 0, 11-19: require the noun to be in the genitive plural

In practice, this means that “4 dogs” and “5 dogs” have a different plural form for “dog”:

чотири^four-NOM собак^dogs-и^NOM.PL
пʼять^five-NOM собак^dogs-$\varnothing$^GEN.PL

This also means that the numerals (that can be inflected themselves!) have to agree with the noun as well, for example the numeral ‘one’ in ‘one dog’ differs based on case:

ukr: один^{one-MASC.NOM.SG} собака^{dog-MASC.NOM.SG}
eng: one dog

ukr: немає^{there’s no} одного^{one-GEN.MASC.SG} собаки^{dog-GEN.MASC.SG}
eng: one dog is missing

Lastly, the same holds for larger numerals (“four million”, “five million”) even if they don’t have to agree with any nouns: “million” (thousand, billion, ..) acts as a noun and four/five acts as a numeral, bringing agreement issues even to a stand-alone cardinal number.

Implications for NLP

All the above has direct implications for NLP, for example:

• The development of lemmatizers, morphological analyses, bag-of-words approaches for information retrieval³¹
• In the area of grammatical error correction, systems developed with English in mind perform worse for morphologically rich languages. ⁵³
• Correctly understanding the word order for the tone/intent/emphasis on specific parts of the sentence, as opposed to the arguably more explicit way English conveys this
• Tools written for Russian can be made to work for Ukrainian but this doesn’t happen automatically, because the vocabulary and grammar are different. TODO
• TODO add more and more recent ones

In the context of this Thesis, inflecting words correctly has been the most challenging aspect:

• In the CBT task, replacement nouns had to be inflected correctly so that morphology could not be used to get the correct answer. One initial area of concern was agreement of nouns with numerals — to put the noun in the correct form there could have been a need to track not just the grammatical number (singular/plural), but also the actual number of entities. At the end, this was handled by just using the form of the target word, which had already the correct inflection, and then manually filtering the edge cases. - TODO edit this when I actually do this, I don’t think I’ll have to track enything at the end - gen-pl can replace gen-pl and complex cases can just be excluded from the list
• In the LMentry-static-UA task, different templates that used numbers (“what is the third word in the sentence”, “what is in the third position in the sentence”, etc.) the numbers had to be correctly inflected by case and gender (слово/‘word’ is neutral, позиція/‘position’ is feminine) as well.
• Morphological analyses (needed for later inflection) required disambiguation, since different morphologies or even different POS can be written identically (‘три’ could be a numeral three, or an imperative verb meaning ‘cancel it!’). A correct disambiguation is crucial for future inflection. This necessitated the creation of a separate python package then used by most of the written tasks.
• An additional edge case in the CBT task was that certain words (‘converb’ or ‘adverbial participles’ that share features of both verbs and participles, e.g. приготувавши/готуючи (‘having prepared’ / ‘while preparing’)), tagged by pymorphy2 as POS GRND( corresponding to the Russian/Ukrainian POS деепричастие⁵⁴/дієприслівник) are encoded in Universal Dependencies as POS VERB with feature VerbForm=Conv⁵⁵ to represent the same concept. And, therefore, are detected as such by spacy’s Morphology. This meant that what spacy detects as VERBs required an additional morphological filtering step to exclude what pymorphy2 would see as GRND, because pymorphy2 isn’t able to inflect between (from its perspective different POS) GRND and VERB.

For list of other typological features of the language, see its page on the World Atlas of Language Studies⁵⁶⁵⁷, as well as the excellent “UD for Ukrainian” page on the Universal Dependencies website⁵⁸.

Eval-UA-tion Ukrainian eval benchmark

Basic description

The benchmark contains 2 main tasks:

• CBT-UA (containing XXX test instances), which involves fill-in-the-gaps questions based on children’s stories. Gaps can be of three types: named entities (defined as animate nouns e.g. ‘Whiskers’ or ’tailor’), common nouns (grain, home), and verbs. The goal is that some understanding of the story (characters’ motivations, etc.) is needed to correctly decide e.g. which character was banished from the forest for stealing, or whether he stole grain (owned by his friend) or chickens (owned by his enemy). The idea is based on the Children’s Book Test task ⁶² but contains many differences from it, most stemming from Ukrainian morphology.
• LMentry-static-UA, which itself is composed of XXX subtasks, some quite different from each other. They are based on tasks that are simple for humans but suprisingly complex for LMs, such as “which word is first in alphabetical order”, “what is the fifth letter of the word ‘orange’”, or “do all words from this list belong to the same category: happiness, sadness, anger, plumber”. It’s based on the LMentry task ⁶³ but departs from it in many ways, form the different subtasks to the change of evaluation mechanism (the original task was scored exclusively by regexes, this task is a dataset with exact anwers, hence the static part in the name).

The tasks and the datasets connected to them are uploaded to the HuggingFace Hub, and EleutherAI lm-evaluation-harness (widely used in literature) ’tasks’ are implemented for each (though not included in the harness itself).

Validation and Human evaluation

Validation of the training instances

As a first step, spot-checks of various training instances of the datasets were performed as sanity check.

LMentry-static-UA

LMentry-static-UA contained exclusively algorithmically generated tasks with little randomness involved, and there the validity of the training instances was especially strongly dependent on the code that generated it — and after looking at enough examples of “what’s the Nth word in this sentence”, one could safely assume the rest were likely to be correct as well. So only a limited subset was manually checked.

The only issue found was wrong ground truth in the task about alphabetical ordering: the canonical order of the Ukrainian alphabet is different from what python’s sorting does (with the Ukrainian-only letters і ї є ґ being sorted at the very end instead of their usual place in the Ukrainian alphabet). The relevant code was rewritten to force the correct expected ordering. (Section XXX* has some reflections on the implications of this in the context of the Bender rule.)

CBT-UA

For the CBT-UA task (which involved creating training instances based on data gained through ML approaches), the filtering of the resulting dataset was much more involved.

There were two rough classes of error sources: those caused by language and those caused by logic.

All the failure modes and their numbers are described its subsection XXX, but suffice to say occasional incorrect lemmatization and POS detection by spacy, incorrect normalization and detection (and therefore inflection) by pymorphy2, and the best-guess approach used in the pymorphy-spacy-disambiguation package (written specifically for this Thesis) created a large area of uncertainty.

On the logic side, there were the unavoidable errors stemming from the task creation approach (despite reasonable safeguards being put in place where practical), such as multiple possible answers, unknowable answers, etc.

• cases where there was more than one correct answer, e.g.
  • if there’s a tailor-turle
  • the turtle is a both a turtle and a tailor, and where a gap contained “turtle” using “tailor” there would be correct as well, and both options are included in possible answers:
  • “the tailor-turtle started sewing/working”: again, working would be a

This dataset is a set of tasks loosely on the original LMentry evaluation task⁶³ described in section XXX.

• TODO note
  • tokenization within sentences (новобранців-іноземців, 100 000)
    • within words: пліч-о-пліч how many LETTERS? what about варʼят?

Differences from LMentry

The original LMentry ⁶³ had a list of 20-XXX partly repetitive tasks, e.g. “bigger number” and “smaller number” being separate ones.

TODO pic taxonomy of LMentry tasks:

LMentry-static-UA (in addition to applying the ideas to Ukrainian) contains the following conceptual changes:

• Only static tasks are included. The original benchmark uses regular expressions for evaluating the tasks in the included scripts, but regexes are (strictly speaking) needed only for the tasks of type “write word/sentence [(not) containing | starting/ending with ] the following word/letter”. To simplify inclusion in other benchmarks, as well as to not require custom evaluation code, these tasks were dropped, and the LMentry-static-UA tasks can be distributed as-is in the form of datasets.
• Tasks are grouped by type, e.g. task type CompareTwoThings is a parent type of LetterCount (containing both ‘more’ and ’less’ letters) and NumberComparison (bigger+smaller) number. This was done to reduce repetitive code and to decrease the number of tasks to contain only conceptually different ones.
• The tasks about first/last entities have been expanded to counting, e.g. in addition to “what is the last word in the sentence” there’s also “what is the fourth letter in this sentence”.
• TODO not yet implemented but will be:
  • The task about comparing two numbers has been expanded to basic comparison tasks, e.g. “the red box contains two million pens and the blue box has five hundred thousand thirteen pens; which box has more pens?”

Dataset structure

The LMentry-static-UA dataset is shared on Huggingface under the link XXX. Since the individual tasks are different, multiple configs are contained in the dataset, with e.g. the NumberComparison subtask being available as

dataset = load_dataset("shamotskyi/lmentry-static-UA", "numbercomparison")

Challenges in the implementation

Agreement

As with other tasks, agreement of Ukrainian numerals and nouns (see section XXX) has taken a large amount of time.

The different templates contained different nouns in the same role (first word, word one, first position, etc.) that required cardinal and ordinal numerals. They had to agree with the noun in gender (number as well, but in practice only singular was needed TODO):

eng: The third word in the sentence is …
ukr: Третє^{third-3SG.N.ORD} слово^word-3SG.N …

This raised two problems.

Encoding and formalization

When creating a template, where/how to encode whether this template requires an ordinal/cardinal and agreed to which grammatical categories.

SOLUTION: including capitalized numerals in the correct form in the template itself and automatically parsing the grammatical categories needed from them:

eng: The FIRST^ORD word in the sentence is …
eng: Word number ONE^CARD in the sentence is …
ukr: ПЕРШЕ^{first-3SG.N.ORD} слово^word-3SG.N …

This allowed to create templates using natural language and simplified the data structures involved.

Creation of the training instances with agreemeent

When constructing the actual training instances from the templates:

1. all capitalized words are morphologically analyzed with pymorphy2 to get the needed grammatical categories
2. the int number needed for the training instance is converted to either ordinal or cardinal numeral in the normal form (NOM.M.SG)
3. the resulting numeral in inflected to match the capitalized word in the template

The implementation of this was challenging, and resulted in the creation of a separate pyhon package, ukr_numbers, which creates numerals based on an input integer and a natural language description of the needed inflection:

>>> from ukr_numbers import Numbers
>>> Numbers().convert_to_auto(15,"перший")
'пʼятнадцятий'

# loosely paraphrasing to English: 
>>> convert_to_auto(15, "first")
"fifteenth"`

Under the hood, it uses num2words to generate Ukrainian ordinals/cardinals in normal form and the already mentioned pymorphy2 to parse the natural language form and inflect the numeral.

The otherwise excellent num2words was not able to inflect Ukrainian ordinals by case, necessitating manual pymorphy2 inflection logic and leading to many edge cases:

• pymorphy2 can analyze and inflect only single words (Ukrainian numerals can contain multiple words)
• disambiguating between different pymorphy2 analyses was complex
  • some cases were trivial, e.g. some words being parsed as both verbs and numerals (три^three-NUM / три^{cancel-2SG.IMP}) was not an issue because we know we’re dealing with numerals
  • some harder but not an issue, e.g. some grammatical categories can’t be disambiguated from the word itself (e.g. перший^{first-ORD.M?/N?} can be masculine or neutral) but this doesn’t matter because after inflection they will be indistinguishable as well
  • etc. TODO
• inflecting multiple-word numerals was a whole bundle of joy
  • ordinals ending in 10^2 or 10^3, 10^6, 10^9 .. are written together (3000 -> тритисячний), others aren’t (3001-> три тисячі перший)
  • in “one/four/five thousand/millions/…”, million acts as a noun, necessitating noun and numeral agreement. And as mentioned in section XXX, nouns take different forms based not on singular/plural, but the actual number involved (plurals aren’t just plurals, 2-3-4 are different from 5+)
    • singular/plural conversions for Ukrainian in pymorphy2 was broken, along with the function make_agree_with_number that depended on it, leading to a bug report⁶⁵ and cumbersome workaround from my side

Not all edge cases are solved, but in all cases relevant to the LMentry-static-UA tasks it works as expected and produces grammatically and semantically correct output.

Children’s book test (CBT)

Basics

TODO The following terms will be used throughout this section:

• A story is divided into two parts, the context segment (the first 65% of the sentences) and the challenge segment (the last 35%).
• The challenge segment contains a gap: the place where a token is masked/removed (replaced with _____).
• The taks is multiple-choice, with options being the 6 tokens provided as possible replacements, only one of them being the correct answer.
• A single test instance (with a gap and corresponding options) is a task instance.

A taxonomy of ways task instances can be wrong

During manual task instance filtering, the task instances were classified into usable and unusable, with the latter removed from the dataset. There were different reasons an instance would be unusable. These reasons were formalized into a simple taxonomy. This was originally done for the people helping with the filtering, in the form of annotation guidelines and with checkboxes in the labeling interface serving chiefly as reminders of the problems to look for.

The errors can be divided into three different (albeit fuzzy) types:

1. Logic/continuity errors:
   • Cause:
     • The way the tasks are created, which doesn’t take into accounts the fact that different words belonging to the classes of the gap may refer to the same entity
     • The decision where to place gaps doesn’t take into account the story narrative (but only the location of the gap, frequency of the lemma, and availability of enough different options)
   • Kinds:
     1. Answer unknown - The story doesn’t contain information that allows the answer to be inferred. - > The Cat and the Turtle go to Cat/Turtle/Lion’s house to sew the coat, and later deliver it to the Lion’s house. - The house is mentioned only once and has no dependencies to the rest of the narrative. One can infer that it’s not the Lion’s house (since it’s clearly a different place they have to go to), but there’s no way to know if it was Cat’s or Turtle’s. - However, if the options were only “Cat/Lion’s house” this would be a valid, solvable instance. - Similarly, if the Cat lived in a castle, this would also be considered a solvable instance.
     2. Multiple options are correct
        • It’s clear what entity/action is involved, but there are multiple options which fit it.

          • The Lion liked the Cat and Turtle’s coat/work. Both tailors/animals were happy.

          • Whiskers was happy that he was a cat: he was fast and could climb trees. One morning, he heard his owner say: “Our Whiskers/cat is the fastest cat I know”.

        • This differs from the previous “answer unknown” case by the fact that there’s no ambiguity about the story itself, only about which word specifically was used.
     3. None of the options is correct
        • Not found in the filtered instances, would have applied if the correct answer was not found in the options list (e.g. through erroneous removal by the task generation script).
     4. Duplicate options
        • Either two identical options (cat/cat) or slightly differing ones but clearly pointing to the same entity.
        • For example, the story has a small bird, occasionally referred to as birdie, both words get lemmatized into two different lemmas, don’t get deduplicated, and both appear as options.
          • In Ukrainian, reflexive verbs ending in “-ся” (-sja) before certain consonants can have the ending shortened into “-сь” (-s’), while remaining the exact same verb
        • Note that if there are two different characters, e.g. the large Bird and the small Birdie, then these words would refer to different characters and this error won’t apply.
        • Differs from “multiple options are correct” by the fact that here it’s not different facets of the same entity (sewing is a type of work), but they are exactly the same entity.
2. Language errors
   • Cause:
     • incorrect filtering of nouns by gender
     • non-existing words introduced to the story itself during generation
     • incorrect morphology parsing, lemmatization/normalization, inflection, and errors in the related code
   • Types:
     1. Ungrammatical words in options
        • Sometimes, the parsing-normalization-inflection pipeline failed in ways that led to words inflected with wrong rules, creating invalid words
          • For example, друг^friend-SG’s plural is друзі^friends-PL. This plural form, when inflected back into singular with pymorphy, resulted in the ungrammatical *друзь^SG. The logic behind this transformation fits some existing inflection paradigms of the Ukrainian language: for example, nouns of Declension III⁶⁶ ending with “-ь” in singular do end with “-і” (тінь-тіні, область-області) in plural. But друг is a Declension II noun, and features a root consonant alternation г->з. In other words, the plural of the Declension II noun gets transformed into singular using Declension III rules, ending up with a whole new ‘word’. This is especially notable because of just how common the word “friend” is.
        • Another source of strange words were the stories themselves. GPT4 (TODO: exact model) especially had difficulties with genders in general, and sometimes attempted to create feminine versions of masculine-only nouns, one notable example being метелиця^snowstorm-F — used as an (incorrect) feminine version of метелик^butterfly-M, which is a masculine noun that has no corresponding feminine. (If it had, метелиця might have been it, since this is exactly how feminine words are often formed: працівник/працівниця.) Most such cases were removed during the story editing process.
     2. Option in the wrong inflection
        • The process that selects and inflects options to the same inflection as the correct answer failed, creating a grammatically correct word that would create an ungrammatical sentence if put in the gap, thereby leaking information.

          • She yelled/speaking at both dogs/cats/butterfly.

            • After ‘both’ clearly a plural is expected, the option ‘butterfly’ is singular and therefore not the correct answer; similarly, the needed verb is definitely not an infinitive.
        • Given the inflectional nature of Ukrainian, the number of different variations of this error were immense.
        • Exceptions to this rule were:
          • The “most frequent (all genders) distractor”, if present, was allowed to be of a different gender.
          • Verbs were inflected by aspect/tense/number/gender/person but this was rarely enough to hide grammatical information, and can be excluded especially by transitivity/intransitivity. This is a known issue and not considered an error in this context.
3. Other errors:
   1. Grammatical errors in the story text itself
   2. Others

Some of these issues were dealt with fixes/rewrites the code, e.g.:

• rewriting some spacy’s lemmas (in the cases where the systematical errors were in frequent nouns; interestingly most such errors seemed to be caused by Russian influence), among the fixed ones were:
  • Миша, Люди (eng: Mouse, People) were parsed as (respectively) the Russian diminutive of the name Михаил/Michael and as the Ukrainian possessive from the diminutive of the name Людмила/Ludmila.
  • кота^cat-SG.ACC67 was lemmatized as кот, a word which doesn’t exist in Ukrainian but is the correct Russian normal form of ‘cat’ (the correct Ukrainian normal form would have been кіт).
  • See Appendix XXX for the full list of rewrites used during task generation.
• simply replacing problematic words in text:
  • *заяць was replaced with заєць^rabbit: GPT4 consistently used the wrong word for rabbit, and was quite emphatic about it being the only correct form when challenged — it isn’t, this word doesn’t exist in Ukrainian except as last name, and the “я” in the root clearly comes from the Russian word for rabbit, заяц.
• blacklisting some common problematic words which were not worth the effort to fix, as well as frequent verbs which weren’t good candidates for either gaps or options.
