摘要：Firstly, this paper expounded that the traditional searching based on keywords has a severe deficiency on Recall and Precision because the computer can't 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
