The Knowledge Seeker is a useful system to develop various intelligent
applications such as ontology-based search engine, ontology-based text
classification system, ontological agent system, and semantic web system
etc. The Knowledge Seeker contains four different ontological
components. First, it defines the knowledge representation model ¡V
Ontology Graph. Second, an ontology learning process that based on
chi-square statistics is proposed for automatic learning an Ontology
Graph from texts for different domains. Third, it defines an ontology
generation method that transforms the learning outcome to the Ontology
Graph format for machine processing and also can be visualized for human
validation. Fourth, it defines different ontological operations (such as
similarity measurement and text classification) that can be carried out
with the use of generated Ontology Graphs. The final goal of the
KnowledgeSeeker system framework is that it can improve the traditional
information system with higher efficiency. In particular, it can
increase the accuracy of a text classification system, and also enhance
the search intelligence in a search engine. This can be done by
enhancing the system with machine processable ontology.
