Tatoeba.org is a free online database of example sentences geared towards foreign language learners. Its name comes from the Japanese term "tatoeba" (例えば tatoeba), meaning "for example". Unlike other online dictionaries, which focus on words, Tatoeba focuses on complete sentences, their grammatical properties, and translating them into other languages. Registration is optional and open to the public, regardless of linguistics background or second language proficiency. Tatoeba was founded by Trang Ho in 2006 and was initially hosted on Sourceforge under the project name "multilangdict".[1] She maintains and administrates the project with Allan Simon, who joined in 2009.[2] Tatoeba is hosted and supported by the Free Software Foundation France.[3]
Content
עריכהAs of March 2011, Tatoeba's corpus has 780,000 sentences in 87 languages. A list of how many sentences there are in each language can be found on Tatoeba's language statistics page. The interface is available in 15 different languages. There are procedures by which one can help to add new interface and content languages.
Tatoeba is also the current home of the Tanaka Corpus, a once public-domain series of about 150,000 English-Japanese sentence pairs compiled by Hyogo University professor Yasuhito Tanaka first released in 2001, and where it is undergoing its latest revisions.[4][5]
Interface
עריכהUsers, even non-registered ones, can search for words in any language to retrieve a list of sentences using that word. Each sentence in the Tatoeba database are displayed next to its translations in other languages; direct and indirect translations are differentiated. Sentences are tagged for content such as subject matter, dialect, or vulgarity; they also each have individual comment threads to facilitate feedback and corrections from other users and cultural notes. Almost 10,000 sentences in 8 languages currently have audio readings. Sentences can also be browsed by language, tag, or audio.
Registered users can add new sentences or translate or proofread existing ones, even if their target language is not their native tongue. Translations are linked to the original sentence automatically. Users can freely edit their own sentences, "adopt" and correct sentences without an owner, and comment on others' sentences. Trusted users, a rank above new users, can tag, untag, link, and unlink sentences.
Database structure
עריכה
Tatoeba's basic data structure is a series of nodes and links. Each sentence is a node; each link bridges two or more sentences with the same meaning.[6]
License
עריכהThe entire Tatoeba database is published under a Creative Commons Attribution 2.0 license,[7] freeing it for academic and other use.
Acclaim
עריכהTatoeba received a grant from Mozilla Drumbeat in December 2010.[8][9]
Usage
עריכהParallel text corpora such as Tatoeba are used for a variety of natural language processing tasks such as machine translation. The Tatoeba data has been used as data for treebanking Japanese [10] and statistical machine translation,[11] as well as the WWWJDIC English-Japanese dictionary.
