Knowledge Acquisition of Domain Ontology Based on the Documents

Abstract:

In this paper we put forward the framework of domain knowledge acquisition based on the documents with the ontology theory and knowledge acquisition theory. We present four aspects of the framework for knowledge acquisition: establishing domain core ontology, text preprocessing, domain ontology knowledge acquisition and improving domain ontology. A core ontology is the core concepts and relationships of the domain area. Text preprocessing mainly analyzes and processes Chinese webpage to generate sets of words. Domain ontology knowledge acquisition parses the core ontology and completes concept matching and ontology editing. Improving domain ontology is to infer and evaluate core ontology expanded and make the ontology more scientific and reasonable. The proposed framework can be applied as a useful benchmark or guidance in domain knowledge acquisition.
