Query Translation using Wikipedia-based resources for analysis and disambiguation

This work investigates query translation using only Wikipedia-based resources in a two step approach: analysis and disam- biguation. After arguing that data mined from Wikipedia is particularly relevant to query translation, both from a lexical and a semantic perspective, we detail the im- plementation of the approach. In the analysis phase, lexical units are extracted from queries and associated to several possible translations using a Wikipedia- based bilingual dictionary. During the second phase, one translation is chosen amongst the many candidates, based on topic homogeneity, asserted with the help of semantic information carried by cate- gories of Wikipedia articles. We report promising results regarding translation accuracy.
