A model for knowledge description and formalization, these various ontologies are widely used to represent various user profiles in personalized web information gathering manner. Represent these user profiles, many of these models have evaluate only their knowledge from either a global knowledge base, and also it called as a user local information. In this paper, a personalized ontology model is introduced for knowledge representation and various reasons over user profiles. ontology model learns ontological user profiles from both a world knowledge base and also an user local instance repositories. The ontology model is also developed by comparing other models and in such way that the results shows that this ontology model is successful.
