Multilingual Corpora in Teaching and Research ( From the series Language and Computers : Studies in Practical Linguistics , No 22 )

Multilingual corpora are those consisting of texts in more than one language, often a monolingual original and a translation. These translations vary greatly in their faithfulness, accuracy, style, and order of presentation, as well as in granularity of translation, that is, the size of the chunks being translated (e.g., word-to-word, sentence-to-sentence, paragraph-to-paragraph, or idea-to-idea). Since the reasons for constructing multilingual corpora include being able to correlate individual pieces of one text with corresponding parts of another, their use immediately raises the problem of text alignment, or computing which chunk of a text in one language corresponds to a given chunk of the parallel text in another language.
