摘要:
Only a few studies have made use of alignment information in bilingual lexicon extraction from comparable corpora, in which comparable corpora are necessarily divided into 1-1 aligned document pairs. They have not been able to show extracted lexicons benefit from the embedding of alignment information. Moreover, strict 1-1 alignments do not exist broadly in comparable corpora. We develop in this paper a language-independent approach to lexicon extraction by combining the classic lexical context with pseudo-alignment information. Experiments on the English-French comparable corpus demonstrate t...
