A Semantic Model and Composition Mechanism for Active Document Collection Templates in Web-based Information Management Systems
In‐Young Ko, Robert T. Neches, Ke-Thia Yao · 2001
Representing semantic information embedded within documents is important, but not sufficient, for the Semantic Web vision of having machines automatically process data found on the Web. Many Web-based information management service tools, such as GeoWorlds (5,13), deal with collections of documents and the services that operate upon them. Semantic modeling of document collections and Web services is essential. We describe techniques for representing semantics of both collections and services, using a lightweight multi-form ontology. These techniques improve the efficiency and reusability of users' work with Web- based information management systems. They help users to set up complex analyses and structurings of information collections to adapt their work for other analyses or for different collections, and to obtain automatic refreshing and updating for collections with content that changes over time. Our semantic representation facilitates identifying and sequencing appropriate analysis and visualization services for a given task. Templates capture these sequences in terms of active semantic relations between document collections created and manipulated during those tasks. Templates can be dynamically modified and instantiated to generate document collections for similar tasks, or to refresh an information space with time-varying document membership. They can also be exchanged, allowing others to reapply them.
