An Agent-Based approach to Adaptive Hypermedia using a link service . The agents are built on top of an agent framework developed at Southampton University.
Personal agents keep a local user model and provide adaptive navigation support.
This is accomplished by extracting keywords found in the user model and through the user s browsing history, and by then replacing occurrences of those words with URL s supplied by a linkbase agent. A third agent provides the ability to query these user models through a web browser. The term Adaptive Hypermedia means personalizing a user s browsing experience. There are a number of different methods for providing this adaptivity in existing hypermedia systems. To facilitate these techniques, a user model is kept by the system, which contains simple personal information, and any concepts and goals the user has acquired while browsing.
