Directed Hypergraph-Based STEP Product Semantic Visual Analysis
Chengfeng Jian, Chunxia Pang, Tao Meng · Journal of Discrete Mathematical Sciences and Cryptography · 2014
Aim at the association with geometric and non-geometric semantic information, directed hypergraph-based semantic visual model is put forward which is an improved semantic visual model for product information semantic visual analysis at first. This model indicates the complex semantic relationship between the entity objects in the STEP product knowledge base. And then the STEP semantic graph is build by means of the corresponding operation such as clustering and decomposition on the STEP Semantic Cell according to the model. At last the visual operation on the STEP semantic information such as semantic link and semantic annotation is put forward. System examples show that it is convenient to unify data layer and semantic layer effectively and then uniforms the geometric semantic and non-geometric semantic information.
