A total of 22 systems (19 neural) from 10 teams were submitted to the task. All four winning systems were neural (two monolingual transformers and two massively multilingual RNNbased models with gated attention). Most teams demonstrate utility of data hallucination and augmentation, ensembles, and multilingual training for low-resource languages. Nonneural learners and manually designed grammars showed competitive and even superior performance on some languages (such as Ingrian, Tajik, Tagalog, Zarma, Lingala), especially with very limited data.

                "text": "Human language is marked by considerable diversity around the world. Though the world's languages share many basic attributes (e.g., Swadesh, 1950 and more recently, List et al., 2016) , grammatical features, and even abstract implications (proposed in Greenberg, 1963) , each language nevertheless has a unique evolutionary trajectory that is affected by geographic, social, cultural, and other factors. As a result, the surface form of languages varies substantially. The morphology of languages can differ in many ways: Some exhibit rich grammatical case systems (e.g., 12 in Erzya and 24 in Veps) and mark possessiveness, others might have complex verbal morphology (e.g., Oto-Manguean languages; Palancar and L\u00e9onard, 2016) or even \"decline\" nouns for tense (e.g., Tupi-Guarani languages). Linguistic typology is the discipline that studies these variations by means of a systematic comparison of languages (Croft, 2002; Comrie, 1989) . Typologists have defined several dimensions of morphological variation to classify and quantify the degree of crosslinguistic variation. This comparison can be challenging as the categories are based on studies of known languages and are progressively refined with documentation of new languages (Haspelmath, 2007) . Nevertheless, to understand the potential range of morphological variation, we take a closer look at three dimensions here: fusion, inflectional synthesis, and position of case affixes (Dryer and Haspelmath, 2013) .",

                "text": "Fusion, our first dimension of variation, refers to the degree to which morphemes bind to one another in a phonological word (Bickel and Nichols, 2013b) . Languages range from strictly isolating (i.e., each morpheme is its own phonological word) to concatenative (i.e., morphemes bind together within a phonological word); nonlinearities such as ablaut or tonal morphology can also be present. From a geographic perspective, isolating languages are found in the Sahel Belt in West Africa, Southeast Asia and the Pacific. Ablaut-concatenative morphology and tonal morphology can be found in African languages. Tonal-concatenative morphology can be found in Mesoamerican languages (e.g., Oto-Manguean) . Concatenative morphology is the most common system and can be found around the world. Inflectional synthesis, the second dimension considered, refers to whether grammatical categories like tense, voice or agreement are expressed as affixes (synthetic) or individual words (analytic) (Bickel and Nichols, 2013c) . Analytic expressions are common in Eurasia (except the Pacific Rim, and the Himalaya and Caucasus mountain ranges), whereas synthetic expressions are used to a high degree in the Americas. Finally, affixes can variably surface as prefixes, suffixes, infixes, or circumfixes (Dryer, 2013) . Most Eurasian and Australian languages strongly favor suffixation, and the same holds true, but to a lesser extent, for South American and New Guinean languages (Dryer, 2013) . In Mesoamerican languages and African languages spoken below the Sahara, prefixation is dominant instead.",

Such cross-lingual variation makes the development of natural language processing (NLP) applications challenging. As Bender (2009 Bender ( , 2016 notes, many current architectures and training and tuning algorithms still present language-specific biases. The most commonly used language for developing NLP applications is English. Along the above dimensions, English is productively concatenative, a mixture of analytic and synthetic, and largely suffixing in its inflectional morphology. With respect to languages that exhibit inflectional morphology, English is relatively impoverished. 1 Importantly, English is just one morphological system among many. A larger goal of natural language processing is that the system work for any presented language. If an NLP system is trained on just one language, it could be missing important flexibility in its ability to account for cross-linguistic morphological variation.",

Similarly, some of its languages have a long tradition of written form, while others have yet to incorporate a writing system. The six branches differ most notably in typology and syntax, with the Chadic language being the main source of differences, which has sparked discussion of the division of the family (Frajzyngier, 2018) . For example, in the Egyptian and Semitic branches, the root of a verb may not contain vowels, while this is allowed in Chadic. Although only four of the six branches, excluding Chadic and Omotic, use a prefix and suffix in conjugation when adding a subject to a verb, it is con-sidered an important characteristic of the family. In addition, some of the families in the phylum use tone to encode tense, modality and number among others. However, all branches use objective and passive suffixes.

LTI focused on their earlier model (Anastasopoulos and Neubig, 2019) , a neural multi-source encoder-decoder with two-step attention architecture, training it with hallucinated data, cross-lingual transfer, and romanization of scripts to improve performance on low-resource languages.

For languages with less than 1,000 training samples, they also generate hallucinated data. CULing developed an ensemble of three (monolingual) transformers with identical architecture but different input data format. The first model was trained on the initial data format (lemma, target tags, target form). For the other two models the team used the idea of lexeme's principal parts (Finkel and Stump, 2007) and augmented the initial input (that only used the lemma as a source form) with entries corresponding to other (non-lemma) slots available for the lexeme. The CMU Tartan team compared performance of models with transformer-based and LSTM-based encoders and decoders. The team also compared monolingual to multilingual training in which they used several (related and unrelated) high-resource languages for low-resource language training. were neural, some teams experimented with nonneural approaches showing that in certain scenarios they might surpass neural systems. A large group of researchers from CU7565 manually developed finite-state grammars for 25 languages (CU7565-01-0). They additionally developed a non-neural learner for all languages (CU7565-02-0) that uses hierarchical paradigm clustering (based on similarity of string transformation rules between inflectional slots). Another team, Flexica, proposed a model (flexica-01-0) conceptually similar to Hulden et al. (2014) , although they did not attempt to reconstruct the paradigm itself and treated transformation rules independently assigning each of them a score based on its frequency and specificity as well as diversity of the characters surrounding the pattern. 7",

Although CULing-01-0 and uiuc-01-0 are both monolingual transformers that do not use any hallucinated data, they follow different strategies to improve performance. The strategy proposed by CULing-01-0 of enriching the input data with extra entries that included non-lemma forms and their tags as a source form, enabled their system to be among top performers on all language families; uiuc-01-0, on the other hand, did not modify the data but rather changed the decoder to be bidirectional and made family-wise fine-tuning of each (monolingual) model. The system is also among the top performers on all language families except Iranian. The third team, DeepSpin, trained and fine-tuned their models on all language data. Both models are ranked high (although the sparsemax model, deepspin-02-1, performs better overall) on most language groups with exception of Algic. Sparsemax was also found useful by CMU-Tartan. The neural ensemble model with data augmentation from IMS team shows superior performance on languages with smaller data sizes (under 10,000 samples).

Mean accuracy was 53.8% with very low variance across systems. Accuracy ranged from 43.5% to 59.0%. The low accuracy is due to several factors. Firstly and primarily, the dataset was created from oral speech samples in various dialects of the language. The Evenki language is known to have rich dialectal variation. Moreover, there was little attempt at any standardization in the oral speech transcription. These peculiarities led to a high number of errors. For instance, some of the systems synthesized a wrong plural form for a noun ending in /-n/. Depending on the dialect, it can be /-r/ or /-l/, and there is a trend to have /-hVl/ for borrowed nouns. Deducing such a rule as well as the fact that the noun is a loanword is a hard task. Other suffixes may also have variable forms (such as /-kVllu/ vs /-kVldu/ depending on the dialect for the 2PL imperative. Some verbs have irregular past tense forms depending on the dialect and the meaning of the verb (e. g. /o:-/ 'to make' and 'to become'). Next, various dialects exhibit various vowel and consonant changes in suffixes. For example, some dialects (but not all of them) change /w/ to /b/ after /l/, and the systems sometimes synthesized a wrong form. The vowel harmony is complex: not all suffixes obey it, and it is also dialect-dependent. Some suffixes have variants (e. g., /-sin/ and /-s/ for SEMEL (semelfactive)), and the choice between them might be hard to understand. Finally, some of the mistakes are due to the markup scheme scarcity. For example, various past tense forms are all annotated as PST, or there are several comitative suffixes all annotated as COM. Moreover, some features are present in the word form but they receive no annotation at all. It is worth mentioning that some of the predictions could theoretically be possible. To sum up, the Evenki case presents the chal-lenges of oral non-standardized speech.",

As in previous years, neural models performed well, even in relatively low-resource cases. Submissions were able to make productive use of multilingual training to take advantage of commonalities across languages in the dataset. Data augmentation techniques such as hallucination helped fill in the gaps and allowed networks to generalize to unseen inputs. These techniques, combined with architecture tweaks like sparsemax, resulted in excellent overall performance on many languages (over 90% accuracy on average). However, the task's focus on typological diversity revealed that some morphology types and language families (Tungusic, Oto-Manguean, South-ern Daly) remain a challenge for even the best systems. These families are extremely low-resource, represented in this dataset by few or a single language. This makes cross-linguistic transfer of similarities by multilanguage training less viable. They may also have morphological properties and rules (e.g., Evenki is agglutinating with many possible forms for each lemma) that are particularly difficult for machine learners to induce automatically from sparse data. For some languages (Ingrian, Tajik, Tagalog, Zarma, and Lingala), optimal performance was only achieved in this shared task by hand-encoding linguist knowledge in finite state grammars. It is up to future research to imbue models with the right kinds of linguistic inductive biases to overcome these challenges. ",
