Abstract

This work investigates the use of external knowledge in a corpus with minimal textual information. We have expanded the original collection with WordNet terms in order to enrich the information included in this corpus. In addition, we have have carried out experiments with original and expanded topics. However, the obtained results show that it is necessary to continue investigating the expansion methodology. The query expansion does not improve the results, although using only the expansion for the corpus slightly achieves better MAP.
