Embodiment Construction
[0056] The present invention provides a distributed service discovery system oriented to semantic Web services. The distributed service discovery system cuts the ontology graph into multiple concept areas (CG, ConceptGroup) through the ontology graph segmentation algorithm, and the concepts in each CG The semantics are similar; and the semantic description information of the service is converted into a CG sequence, that is, the code that generates a variable-length concept region combination sequence; at the same time, the nodes in the distributed service discovery system correspond to the concept region sequence, forming a structured semantic P2P network. Web service discovery is achieved through a strategy based on prefix-semantic routing that supports conceptual region sequences.
[0057] If the ontology graph is divided into K CGs, the length of the CG sequence corresponding to the service query request is L, where L≤K. Distributed service discovery can find the node set o...
