摘要：

Aiming at the problems of knowledge organizing, retrieving and sharing led by multidisciplinary intersection of design fields and large amount of knowledge resources in complex products, a new method of knowledge representation based on dimension of disciplinary domains was proposed, which realized the structuralization, dimensionalization and standardization of knowledge representation in electronic products' design by taking the domain ontology as a semantic model. On this basis, a novel semantic annotation framework in regard to design documents was designed. As the base of the framework, the conceptual semantic similarity of multifactor comprehensive weighted algorithm was created with domain ontology, which could describe the semantic relationship between the concepts. The semantic increment was also introduced to calculate the semantic weight of keywords, thus the technical documents were classified into different disciplinary domains in a more accurate way consequently. The knowledge management system of radar's design was taken as an example to validate the efficiency and accuracy of the proposed method. © 2016, Editorial Department of CIMS. All right reserved.
