GATITOS Multilingual Lexicon

The GATITOS (Google's Additional Translations Into Tail-languages: Often Short) dataset is a high-quality, multi-way parallel dataset of tokens and short phrases, intended for training and improving machine translation models. Experiments on this dataset and Panlex focusing on unsupervised translation in a 208-language model can be found in BiLex Rx: Lexical Data Augmentation for Massively Multilingual Machine Translation.

About the Data and Data Collection

This dataset consists in 4,000 English segments (4,500 tokens) that have been translated into each of 173 languages, 170 of which are low-resource, and three of which are mid-high resource (es, fr, hi). All translations were made directly from English, with the exception of Aymara, which was translated from the Spanish.

This dataset contains primarily short segments: 93% single tokens, and only 23 sentences (0.6%) have over 5 tokens. As such it is best thought of as a multilingual lexicon, rather than a parallel training corpus. The source text is frequent words in the English Language, along with some common phrases and short sentences. Care has been taken to ensure that they include good coverage of numbers, months, days of the week, swadesh words, and names of the languages themselves (including the endonym).

Single tokens are remarkably fickle to translate because of the common issue of polysemy. Some languages in this dataset only provide one translation per source token; others provide multiple translations. When multiple translations are given, they are broken up into multiple lines. Therefore, you can get the average number of translations per token by looking at the number of lines in the file versus the number of deduplicated English lines in the file. The three languages with the most average translations per English token are Betawi, Kachin, and Occitan, each with over 1.5 on average.

Sometimes translators have left annotations like "pike (verb)", "او (مونث)", "фамили(я)", "أسوأ(repeated)" etc.. Wolof is particularly noticeable in this regard, with notes like "xont (verb) which means to feed an animal". Several languages also give definitions instead of translations for some words, e.g. Tok Pisin translation of mole" to "wanpela liklik animal we i save stap long hol long graun".

Please note that the language name can be a point of considerable tension, and there is rarely a "right" name for a language! This said, here are some non-exhaustive notes that went into the names in the second column above, based on conversations with speakers. We welcome more comments from the community:

• ak: Calling this language "Twi" instead of "Akan" here is reflective of the corresponding translation models active on Google Translate. These are likely to mix different Akan dialects, including Twi proper, Fante, Akuapem Twi, etc.. Therefore, from a linguistic perspective, one would call this "Akan" and use the corresponding code "ak". However, this is a more academic word for the language; according to native speaker consultants, "Akan" is usually used to describe the ethnic group rather than the language, so they suggested simply calling this "Twi", which is most likely accurate for the large majority of model outputs.
• ckb: Central Kurdish is a more academic name that may not be as widely known to speakers of the language, so Sorani is preferred -- though they are both acceptable.
• dv: There is not a consistent romanization of this language, and both Divehi and Dhivehi are common. The first consonant in this language is a dental, non-aspirated d. When transliterating Indian language names there is no standard about how to represent this sound. In the south, "dh" usually refers to the dental consonant; in the North, it just as often refers to the aspirated one. However, in both cases, it is common that "d" alone would represent the retroflex consonant, so it is possible that Divehi would be mispronounced more often.
• gom: Technically, gom is the code for Goan Konkani only. Other varieties of Konkani, like Mangalore Konkani (which oddly enough does not have an ISO code), are mutually unintelligible! There is certainly dispute about whether to treat Konkani as one language or not.
• ilo: Native speakers give a variety of different answers around the correct name. Some say that Ilocano is more formal, whereas Ilokano is more informal; some say that both of these actually refer to the people, and that Iloko is the only correct term for the language.
• lg: Speakers usually refer to this language as "Luganda"; linguists sometimes call it "Ganda", but like Sepedi, this is not usually used by people familiar with the language.
• lus: There is agreement that Lushai is an obsolete colonial name and should not be used. Mizo is the preferred name.
• mni-Mtei: The conventional and most common name for this language is Manipuri. However, in reality, this is only the language of one of the many ethnicities in Manipur, so that name can be seen as offensive to some. Therefore, we use the endonym Meiteilon, with the conventional name (Manipuri) in parentheses.
• nso: Although a linguist might say that Sepedi is a dialect of Northern Sotho, speakers often say that they call the whole language Sepedi, and that Northern Sotho has offensive colonial overtones. Others, however, may disagree with this. The endonym Sesotho sa Leboa is not uncommon. There is agreement that no-one uses Pedi.
• qu: These translations are technically in Southern Quechua. However, this is a point of some contention. Some will opine that "Quechua" is not a language but a family of languages. Others, however, say that they all feel like one language, and that the regional differences are slight, and it's easy for Peruvians, Bolivians, and even Ecuadorians to understand each other. The majority opinion among the naive speakers we talked to seemed to be closer to the latter, so we have opted for the name "Quechua".
• ti: In Tigray Tigrigna is the most common Romanization, and in Eritrea Tigrinya is.
• zap: Linguists usually talk about the Zapotec languages, rather than considering Zapotec a single language. However, just as with Quechua above, conversations with a native speaker indicated that they perceived Zapotec as one language, with a variety of local variants that are all easy enough to understand (excepting one or two). A broader survey would help resolve this question.
• Those languages in this dataset that are not on Google Translate have yet to undergo a more careful name review; if you see a name in the list above that you want to correct, please contact us!

Note on language codes:

• we use chm for Meadow Mari, although chm is properly the superset, and mhr is the individual code for Meadow Mari.
• Similarly, we use rom for all Romani dialects, ak for Twi (see note above), and ff for all Fulfulde dialects.
• We use fa-AF and ar-MA for Dari and Darija respectively. The specific codes prs and ary are probably more precise.
• apd-SD and ndc-ZW are probably redundant; apd and ndc alone refer to Sudanese Arabic and Ndau resp.

Special note on Bantu languages: Bantu language names have a special noun-class prefix for languages, like xiTsonga, sePedi, kiSwahili, isiZulu, luGanda, siSwati, isiNdebele, tshiVenda, and so on. However, there is no pattern as to whether this prefix is used in the conventional English form of the name. For instance, Xhosa usually leaves off the isi- in English, whereas Lingala almost never leaves off the li-. Others, like (xi)Tsonga, seem to be frequently used in both forms. Linguistic resources occasionally strip the prefixes, yielding names like "Ganda", "Pedi" and so on, perhaps out of a desire for consistent handling of the noun class prefix. (Even the ba in Bantu is such a prefix, so these languages are sometimes called the Ntu languages!)
