heal.abstract	Modern Information Retrieval Systems match the terms contained in a user's query with available documents through the use of an index. In this work, we propose a method for expanding the query with its associated terms, in order to increase,the system recall. The proposed method is based on a novel fuzzy clustering of the index terms, using their common occurrence in documents as clustering criterion. The clusters which axe relevant to the terms of the query form the query context. The terms of the clusters that belong to the context are used to expand the. query. Clusters participate in the, expansion according to their degree of relevance to the query. Precision of the result. is thus improved. This statistical approach for query expansion is useful when no a priori semantic knowledge is available.	en
