Assessing automatically extracted bilingual lexicons for CLIR in vertical Domains
Jean-Michel Renders, Hervé Dejean, Eric Gaussier
In this paper, we describe the methods we used for the cross-lingual evaluation forum CLEF 2002, and more
specifically for the GIRT Task. The methods are based on (1) the extraction of the two bilingual lexicons, one
from parallel corpora and the other one from comparable corpora, (2) the optimal combination of these
bilingual lexicons in Cross-Language Information Retrieval and (3) the combination with monolingual IR
on parallel corpora. While our original submission to CLEF2002 was restricted to short queries (using only
the title field), we present here the results extended to compete queries.
