The Semanticization, Personalization, and Socialization of Geospatial Web Resource Discovery

Project Details


With the advance of the World-Wide Web (WWW), general publics are able to easily share geospatial data or services on the Web. The collection of these geospatial data and web service is defined as the GeoWeb (Geospatial Web). Similar to the WWW, while more and more geospatial resources are shared online, users face difficulties in finding resources on the GeoWeb. Although users can find geospatial resources in platforms like data portals and spatial data infrastructures, no platform indexes all the GeoWeb resources and no user knows every platform on the Web. From previous years, we have proposed a GeoWeb Search Engine and have constructed a preliminary prototype. In this proposal, we try to extend the discussion by proposing extensions to the existing GeoWeb Search Engine. To be specific, the proposed solution includes (1) semanticizing GeoWeb resources to understand and integrate resources based on their meanings, (2) a personalized search ranking algorithm based on the understanding to a user’s interest, and (3) extending a user’s interests based on the interests from similar users or communities. Overall, we believe that the proposed solution can further address the GeoWeb resource discovery issue, which will significantly reduce the time users spent on searching for GeoWeb resources, and consequently promote the use of geospatial information in various domains.
