Legal Query Expansion using Ontologies and Relevance Feedback.

Abstract

Abstract. The aim of our research is the improvement of Boolean search with query expansion using lexical ontologies and user feedback. User studies strongly suggest that standard search techniques have to be improved in order to meet legal particularities. Query expansion can exploit the potential of linguistic knowledge and successful user behaviour. First tentative results show the feasibility of our approach. A first search prototype has been built and tested in the area of European state aid law.
