Abstract

We applied a Cross-Lingual PRF (Pseudo-Relevance Feedback) system to both the monolingual task and the German->English task. We focused on the effects of extracting a comparable corpus from the given newspaper data; our corpus doubled the average precision when used together with a parallel corpus made available to participants. The PRF performance was lower for the queries with few relevant documents. We also examined the effects of the PRF first-step retrieval in the parallel corpus vs. the entire document collection.
