Intelligent Interfaces for Database Fuzzy Querying

Intelligent interfaces to database querying must offer to the user a flexible wayto express the selection criteria. Some software tools are developed in our departmentfor scientific purpose: to be used for studying flexible queries. There are two majoraspects of the queries’ flexibility that are interesting: natural language (Romanian)querying and vague querying1 . They are studied and implemented either separately orboth combined. For the natural language processing, the intermediary languageapproach is adopted. The queries vagueness is modelled and processed using the fuzzylogic technique. All presented software tools (and more others not presented here) areimplemented in collaboration with our Computer Science students.
