dc.description.abstract | We investigate the problem of handling of failing queries involving fuzzy predicates. We propose an approach that leverages data distribution of the target database. It consists in two steps: i) Query translation that aims at translating the failing fuzzy query into a crisp query by means of a particular semantic distance between sets; ii) Query relaxation which consists in expanding the translated query criteria with similar values. To rank-order the approximate query results, a method is proposed | en_US |
