A Study on Ontology-Driven Geospatial-Information Retrieving in the Semantic Web
Firstly,this paper expounded that the traditional searching based on keywords has a severe deficiency on Recall and Precision because the computer cant understand what information mean efficiently.In Succession,through extending from ordinary information to Geo-spatial information,on the support of geo-ontology theory and semantic web services technology,this paper discussed the principle,methods and application of ontology-driven geo-spatial information retrieving mechanism in semantic web.In other word,How to structure the framework for running this mechanism,how to build the ontology information models and how to establish the ontology-driven services models are discussed in detail in context.A design of systems for implementing the mechanism and experiment are given at the end of the text.
