Automatic semantic annotation method for complex product design-knowledge

Aiming at the existing problems in semantic annotation of complex product design-knowledge, such as time-consuming, low accuracy and in complete expression of knowledge semantic information, an automatic semantic annotation method based on semantic space was proposed. In this method, the process of domain ontology construction and the framework of multi-dimensional ontology construction were proposed according to the characteristic of complex product design-knowledge. On this basis, the realization process of automatic semantic annotation was given. The knowledge preprocessing and ontology parser, semantic matching, semantic space generating and annotation result conversion were elaborated in detail. An experiment was performed in a prototype system of armored vehicle design-knowledge management, and the result showed that the proposed method could improve the efficiency of semantic annotation and semantic retrieval greatly.
