Term expansion using stemming and thesauri in Spanish Zazo Rodríguez, Ángel Francisco García de Figuerola Paniagua, Luis Carlos Alonso Berrocal, José Luis Rodríguez Vázquez de Aldana, Emilio Recuperación de la información Thesaurus Information retrieval 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 semantic 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. 2009-10-15T10:28:21Z 2009-10-15T10:28:21Z 2009-10-15T10:28:21Z 2002 info:eu-repo/semantics/article info:eu-repo/semantics/article Zazo Rodríguez, A.F., García Figuerola, L.C., Alonso Berrocal, J.L. y Rodríguez Vázquez de Aldana, E.
