摘要：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 querying1 . 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.
