Abstract

An advanced bookmark database system provides query, re-organization, information sharing, view, and access control capabilities to manage bookmarks. In one embodiment of the bookmark database system of the present invention, HTML document parsing, keyword extraction, and HTML/VRML document generation capabilities are provided, in addition to allowing comprehensive database query and navigation. The bookmark database system extracts document content semantics, intra-document structures, inter-document linkage, and useful metadata for users to allow query and organization based on various attributes, such as keywords, domains, and last visit times. Further, an access control capability allows sharing of bookmark databases among users. Multiple physical or logical bookmark databases can be merged to create new bookmark databases. Multiple bookmark databases can be organized as a hierarchical structure, to allowing grouping by individuals, projects, groups, departments, etc. Automated query dispatch and dynamic links capabilities are provided. Dynamic links cross references multiple bookmark databases according to bookmark content semantics or other criteria. A user interface provides visualizing models for organizing accessible physical or logical bookmark databases.
