Method for Searching Semantic Resource Using Semantic Space Mapping of Resource

摘要

A method for searching semantic resources with semantic space mapping of resource is provided to distribute load among servers by searching the desired resources based on semantic with expandability if many resources are present under large scale ubiquitous computing environment. A first resource description of a landmark representing the reference resources and the second resource description of the desired resources are expressed in ontology with attribute-value relation. Property similarity of attribute/value is calculated by finding the shortest length and a common node height for attribute/value of the first and second resource description, and substituting the shortest length and the common node height for a parameter of a property similarity function. Semantic coordinates of the desired resources are found in a semantic coordinate space by substituting the property similarity of the attribute/value for the parameter of a semantic distance function(S100).
