Abstract

This paper reports on experiments submitted for the robust task at CLEF 2007. We applied a system previously tested for ad-hoc retrieval. Experiments were focused on the effect of blind relevance feedback and named entities. Experiments for mono-lingual English and French are presented. A topic analysis of post run results shows directions for future research.
