Problems solved by technology

[0004] In the process of service discovery, service description language is the key to realize service description and matching. However, the existing service description language has the problem of heterogeneity between user requirement description and service description, which directly affects the efficiency of service discovery.

Abstract

The invention discloses an ontology-based user requirement description method, and belongs to the technical field of Web service discovery. The method includes introducing open directory information and constructing user characteristic information ontology with reference to relevant concepts and rules of OWL language; constructing user characteristic information description documents; mapping from user characteristic information description documents and user characteristic information ontology to user characteristic information description documents Relational construction of a set of user requirement descriptions with semantic information solves the problem of heterogeneity between user requirement descriptions and service descriptions, and improves the efficiency of service discovery.

Description

technical field [0001] The invention discloses an ontology-based user requirement description method, and belongs to the technical field of Web service discovery. Background technique [0002] Against the backdrop of global economic integration and informatization progress, the pattern of the information industry is constantly changing with the integration of information technology and the development trend of service. The information service industry has become an important impetus for the sustainable development of the national economy. strength. Service-oriented research is an important change in the information age, and the understanding and communication between information technology and business operators can be promoted through services. Service discovery is an important link in the service-oriented architecture, which refers to the process that the service requester finds the target service set from the registration center through the service discovery algorithm ac...
