Abstract
The paper presents an overview of the system build and experiments performed for the CLEF 2007 CL-SR track by the University of West Bohemia. We have concentrated on the monolingual experiments using the Czech collection only. The approach that was successfully employed by our team in the last year’s campaign (simple tf.idf model with blind relevance feedback, accompanied with solid linguistic preprocessing) was used again but the set of performed experiments was broadened and a more detailed analysis of the results is provided.
This work was supported by the Ministry of Education of the Czech Republic project No. LC536 and the Grant Agency of the Czech Academy of Sciences project No. 1QS101470516.
