Cristiane A. YaguinumaMauro BiajizMarilde T. P. Santos

As availability of data has been growing, it is becoming even more necessary to develop effective techniques to retrieve the desired information, in order to reduce irrelevant answers and ensure that relevant results are not ignored. In this sense, this paper presents the FOQuE system, developed to perform semantic query expansion based on fuzzy ontologies, making possible to retrieve approximate results that satisfy user requirements according to expansion parameters deFIned by him. The additional answers retrieved by the FOQuE system are classiFIed regarding both the semantic expansion performed and the relevance to the query, therefore improving the way results are presented to the user.
