Most models and techniques employed in Information Retireval at some time or other use frecuency counts of the terms appearing in both documents and queries. Many words that derive from the same stem have a close semantic content. Locating stems common to several words and grouping them by replacing them with the corresponding stem can improve the working of these systems. Stemming procedures differ, however, depending on the different languages. We describe a stemmer for Spanish and the tests carried out by applying it to Information Retrieval.
