Abstract:
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.
Keywords: Ontology, Internet, WWW, information gathering,
information classification, information extraction and reorganization
