CogNet is a large-scale database of cognate pairs: CogNet v2 contains 8.1 million cognates in 338 languages, 38 writing systems, and 91285 concepts. Its quality is manually evaulated at 94% precision. It was automatically constructed from wordnets and dictionaries contained within the UKC resource, as described in our paper. For 37 different orthographies of 338 languages, we used the Wiktionary tranlisteration, WikTra, developed by Wiktionary linguists and developers.

UKC resource is at http://ukc.disi.unitn.it, and more details of CogNet is at http://cognet.ukc.disi.unitn.it/

In Computational Linguistics: improve the cross-lingual NLP tasks, e.g., word translation, bilingual lexicon induction, cross-lingual knowledge transfer.

Besides downloading the entire CogNet as a structured text file, you can also use the Linguarena website to display and browse (currently an older version of) cognate data interactively on a world map, as also shown in the figure above. The fish example is on this link

Each line represents one instance of a pair of cognate words. Columns are separated by TAB.
