A wiki system is a typical Web 2.0 application that provides a bi-directional platform for users to collaborate and share much useful information online. Unfortunately, computers cannot well understand the wiki pages in plain text. The user-generated geographical content via wiki systems cannot be manipulated properly and efficiently unless the geographical semantics is explicitly represented. In this paper, a geographical semantic wiki system, Geo-Wiki, is introduced to solve this problem. Geo-Wiki is a semantic geographical knowledge-sharing web system based on geographical ontologies so that computers can parse and storage the multi-source geographical knowledge. Moreover, Geo-Wiki mashed up with map services enriches the representation and helps users to find spatial distribution patterns, and thus can serve geospatial decision-making by customizing the Google Maps APIs.
