Description
Summary:Topic Maps (TM) are standardized by ISO 13250 for the purpose of semantic annotation of WWW resources. XML Topic Maps (XTM) is straightforwardly usable over the Internet and support a wide variety of applications. This paper presents the knowledge navigation system for city information portal based on XML Topic Maps technology, including four layers: information resources layer, knowledge layer, information navigation server layer and application layer. The method of constructing topic maps from domain ontology is discussed. The knowledge layer is abstracted from large quantities of distributing heterogeneous municipal information resources by using XTM. Navigation scope is built on the knowledge level which enlarges the navigation unit granularity and quantity of receiving information, shortens the navigation routing, and improves the efficiency of navigation. The research is valuable in digital city and knowledge navigation.
