Abstract

Aiming at the problem that no representation can realize completely expression, intelligibility and easy operation, a method of knowledge representation based on ontology is adopted and it is applied to product case. The discrimination of case similarity is the foundation of case retrieval. Considering the influence on similarity from attribute, an improved similarity algorithm is presented. Hierarchical retrieval based on attribute tables is used. Then the best case is properly searched. Finally, a cleaner as an example is provided to illustrate the validity about the case retrieval.
