Effective compositional model for lexical alignment

The automatic compilation of bilingual dic-tionaries from comparable corpora has been successful for single-word terms (SWTs), but remains disappointing for multi-word terms (MWTs). One of the main problems is the insufcient coverage of the bilingual dic-tionary. Using the compositional translation method improved the results, but still shows some limits for MWTs of different syntac-tic structures. In this paper, we propose to bridge the gap between syntactic structures through morphological links. The results show a signicant improvement in the com-positional translation of MWTs that demon-strate the efciency of the morphologically based-method for lexical alignment.
