English abstract

The objective of our participation this year in the Spanish monolingual task at CLEF2002 is to continue the study in term expansion. Last year we showed results in stemming. Now, our effort is centered in term expansion using thesauri. Many words that derive from the same stem have a close romantic content. However other words with very different stem origin have near semantic sense. In this case, the analysis of the word relationships in document collection can be used to construct a thesaurus of related terms. After, the thesaurus is used to expand a term with the best related terms
