Abstract: In order to provide knowledge expression in the product lifecycle management process so as to realize product semantic information communications cross departments, starting from ontology expression of product information, the ontology mapping method oriented to semantic information collaboration in the manufacturing process was discussed. Similarity rules for finding ontology mapping relationship amongst enterprise sectors were defined. And decision making tree model was adopted to optimize ontology mapping process. The semi-automatic approach of finding ontology mappings could reduce user manual work in the process of information collaboration. Finally a case of retrieving designing information by users was used to validate the research issues hereof.
