Empirical Methods for Exploiting Parallel Texts

Parallel texts (bitexts) are a goldmine of linguistic knowledge, because the translation of a text into another language can be viewed as a detailed annotation of what that text means. Knowledge about translational equivalence, which can be gleaned from bitexts, is of central importance for applications such as manual and machine translation, cross-language information retrieval, and corpus linguistics. The availability of bitexts has increased dramatically since the advent of the Web, making their study an exciting new area of research in natural language processing. This book lays out the theory and the practical techniques for discovering and applying translational equivalence at the lexical level. It is a start-to-finish guide to designing and evaluating many translingual applications.

Textele paralele (bitexturi) sunt o mina de aur a cunostintelor lingvistice, deoarece traducerea unui text in alta limba poate fi privita ca o adnotare detaliata a ceea ce inseamna textul respectiv. Cunostintele despre echivalenta translationala, care pot fi extrase din textele bitext, sunt de o importanta centrala pentru aplicatii precum traducerea manuala si automata, recuperarea informatiilor in mai multe limbi si lingvistica corpusului.
