A fuzzy logic system for classifying the contents of a database and searching consultations in natural language

摘要

This paper presents a method for the classification of the contents in a database in order to answer to user consultations using natural language. Artificial intelligence (AI) is used to relate these consultations to the database contents. The system is based on a fuzzy logic engine to take advantage of its so suitable properties for this application and is ideal for sets of accumulated knowledge that can be built in hierarchic levels by a tree structure. The eventual aim of this system is the implementation of a virtual Web assistant for an Internet portal.
