Research on Semantic Similarity and Correlativity of Land-Use Concept in Classification System Based on HowNet
The relation among geographical domain ontology concepts is very complicated, how to present semantic relationship among different geographical concepts and discovery geographical information service is a difficult task. The paper takes land-use classification as an example, starting from fountainhead of geographical event and considering natural and social characteristics of land-use concepts, constructs concepts system graph of land-use ontology based on HowNet, and calculates semantic similarity and correlativity among land-use ontology concepts based on semantic similarity and correlativity algorithm of HowNet sememe, expresses complicated relation among ontology concepts from different sides, satisfying needs of Web service discovery and matching of geographic information.
