Extending UML for a Context-Based Navigation Modeling Framework of Web Information Systems

摘要

Web information systems are rapidly increasing and the structure of the systems becomes more complex. When users, however, navigate such complex Web systems, they cannot often grasp the current location and get the information that they want. Therefore, a systematic approach to model the navigation of Web information systems is needed that helps users get information, purchase products, and deal with complexity. If the systems provide the information of their navigation context with useful clues for exploring, users will easily comprehend the present situation and find the information in a relatively short time. They will also travel through the systems adaptively by using the context information. In this paper, we describe extending UML for a context-based navigation modeling framework of Web information systems. An example of online bookstore is given to describe the models produced in the framework.
