Intelligent Interfaces for Database Fuzzy Querying

Abstract

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