Abstract

This paper brought forward ontology-based information retrieval model and constructed a prototype model. By combing information retrieval approach with ontology, this paper used domain ontology to extend the original keywords input by users and calculates the concept similarity. The experiment results prove that this method is feasible and the computational results are reasonable.
