document: Toward tighter integration of web search with a geographic information system Integration of Web search with geographic information has recently attracted much attention . There are a number of local Web search systems enabling users to find location-specific Web content . In this paper , however , we point out that this integration is still at a superficial level . Most local Web search systems today only link local Web content to a map interface . They are extensions of a conventional stand-alone geographic information system ( GIS ) , applied to a Web-based client-server architecture . In this paper , we discuss the directions available for tighter integration of Web search with a GIS , in terms of extraction , knowledge discovery , and presentation . We also describe implementations to support our argument that the integration must go beyond the simple map-and hyperlink architecture .
