Research on building computation of ontology-based knowledge base

Construction of a knowledge base is the fundamental of any computation knowledge sharing project. This research is aimed to explore a methodology of building an ontology-based knowledge base in relational database. It is proposed that a metadata model of ontology is the essential element for ontology design of knowledge. The extended entity relationship model is also offered as the design method for modeling structural knowledge. Finally, the knowledge of data integrity of relational database is adopted as the example to implement a simple ontology-based knowledge base on Oracle 11gXE database for verification.
