Uncertainty in information retrieval: an approach based on fuzzy sets
Dario Lucarella · 1990
Design and implementation issues are discussed for a fuzzy information retrieval system using a knowledge-based system approach. In this context, system performance is identified as a critical point, and heuristics are suggested for a constrained spreading activation in the knowledge base and for optimization of the retrieval procedure. The design and implementation issues outlined are being tested in a prototype system named FIRST (Fuzzy Information Retrieval SysTem), which is being implemented in Prolog on a personal workstation.>
