A Total Solution for the Open Geospatial Web Resource Discovery(2/3)

Project Details


With the advance of the World-Wide Web (WWW), general publics are able to easily share geospatial dataor 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, usersface difficulties in finding resources on the GeoWeb. Although users can find geospatial resources inplatforms like data portals and spatial data infrastructures, no platform indexes all the GeoWeb resourcesand no user knows every platform on the Web. Therefore, we argue that a general solution for addressingthe geospatial resource discovery issue is necessary. In order to solve the GeoWeb resource discoveryproblem, this proposal presents a comprehensive solution, including (1) open GeoWeb resource crawlerproactively discover and index GeoWeb resources, (2) GeoWeb search engine integrate variousinformation to provide ranked results that are most suitable for users’ needs, (3) GeoWeb resourcevisualizer provides lightweight and efficient GeoWeb resource visualization platform, (4) GeoWeb onlinesocial network helps establish personalized and social-network-based search ranking algorithm, (5)push-based GeoWeb resource discovery framework recommends resources based on users’ subscriptionsor social network information, and (6) semantic-based GeoWeb resource integration categorize resourcesbased on semantic information to improve the search ranking and recommendation. Overall, we believe thatthe proposed solution is the solution for the GeoWeb resource discovery issue. Similar to Web searchengines have improved the web resource discovery efficiency, our solution will significantly reduce thetime users spent on searching for GeoWeb resources, and consequently promote the use of geospatialinformation in various domains.
