A Domain Ontology-based Information Retrieval Approach for Technique Preparation

In order to realize information sharing and information reuse of technique preparation process, idea of domain ontology was applied in technique preparation process. The concept of technique preparation domain ontology was proposed and its structure was designed. Moreover, the information retrieval framework for technique preparation based on domain ontology was put forward and the flowchart of the proposed approach was designed. Furthermore, the similarity relation between concepts was elaborated and the similarity computing approach of domain ontology was designed to resolve the problem of technique preparation information similarity. Finally, an application case was illustrated and the information retrieval approach was proved efficient. (C) 2012 Published by Elsevier B.V.
