Fuzzy Queries in Romanian Language. An Intelligent Interface

Abstract

The most accessible interfaces querying databases must be so intelligent, able to understand natural language expressions and including vague terms in selection criteria. The paper proposes a general architecture for a flexible database interface and also a real implementation of such a system. It is general enough, so it can be connected to any database, after a specific knowledge base description. The natural language processing is mainly based on lexico-syntagmatical analyse; the vague criteria interpreting and evaluating are based on the fuzzy logic.
