In this paper, we present a system called IICA (Intelligent Information Collector and Analyzer) which gathers, classifies, and reorganizes information from the Internet. Ontology plays an important role in IICA. It specifies the common background knowledge shared by the user and IICA, allows IICA to make inexact match between the user’s request and the candidates, and assigns user-oriented categories. IICA extracts information using a state transition network grammar and concept frames. We have implemented and evaluated IICA. The results shows the feasibility and robustness of the approach.
