Automatic Construction of a MultiWord Expressions Bilingual Lexicon: A Statistical Machine Translation Evaluation Perspective
Dhouha Bouamor, Nasredine Semmar, Pierre Zweigenbaum · 2012
Identifying and translating MultiWord Expressions (MWES) in a text represent a key issue for numerous applications of Natural Language Processing (NLP), especially for Machine Translation (MT). In this paper, we present a method aiming to construct a bilingual lexicon of MWES from a French-English parallel corpus. In order to assess the quality of the mined lexicon, a Statistical Machine Translation (SMT) task-based evaluation is conducted. We investigate the performance of three dynamic strategies and of one static strategy to integrate the mined bilingual MWES lexicon in a SMT system. Experimental results shows that such a lexicon improves the quality of translation.
