| Abstract(in English) | Most of the casual users always use very short queries in information retrieval, and cannot be expected to take the trouble to formulated longer and more elaborate queries that can further improve the accuracy of their retrieval results. The well-known method to deal with this issue is automatic query expansion. In this paper, we propose a method to increase the accuracy of the retrieval results by not only using keywords from the queries but also a taxonomy. A user gives keywords as a query to the system, and at the same time he/she selects from the taxonomy a context node of the query. After retrieving initial results, system then uses the taxonomy to classify the results. Documents classified to the context node and its descendants are considered relevant to the query, while the others are considered non-relevant. Based on the relevancy of the documents, the system constructs a rule-based classifier and used the rules from the classifier to expand the query. |
