Abstract

The paper provides a brief description of the system assembled for the CLEF 2007 Ad-Hoc track by the University of West Bohemia. We have performed only monolingual experiments (Czech documents - Czech queries) using two incarnations of the tf.idf model - one with raw term frequency and the other with the BM25 term frequency weighting - as implemented in the Lemur toolkit. The effect of the blind relevance feedback was also explored. Czech morphological analyser and tagger were used for lemmatization and stop word removal.
