Final Call for Participation International Conference on Adaptive Hypermedia and Adaptive Web-based Systems (AH2000) 28-30 August 2000, ITC/IRST Trento, ITALY Sponsored by the European Commission: High Level Scientific Conference Program Co-sponsored by IJCAI and Kluwer Academic Publishers In cooperation with ACM SIGART, SIGCHI, SIGIR, and SIGWEB ** All information including the final schedule can be found at http://AH2000.itc.it/ ** Web-based application systems, as well as other complex hypermedia systems with a large variety of users, suffer from an inability to satisfy heterogeneous needs. A Web course presents the same static explanation of a concept to students with widely differing knowledge of the subject. A Web bookstore offers the same selection of bestsellers to customers with different reading preferences. A Web museum offers the same "guided tour" and the same narration to visitors with very different goals and interests. A remedy for the negative effects of the traditional "one-size-fits-all" approach is to enhance a system's ability to adapt its own behavior to the goals, tasks, interests, and other features of individual users. Starting in the 1990s, many research teams began to investigate ways of modelling features of the users of hypermedia systems. This has led to a number of interesting adaptation techniques and adaptive hypermedia systems. The Web, with its clear demand for personalization, served as a real booster for this research area, providing both a challenge and an attractive platform. The AH2000 Conference continues from a series of successful workshops on the topic of adaptive hypermedia and adaptive Web applications. It will provide a forum in which researchers and practitioners with different backgrounds can exchange their complementary insights. The conference aims to promote a cross-fertilisation of ideas and highlight the prospects for future collaboration. Conference Scope Topics of interest include but are not limited to: - adaptive hypermedia systems and techniques - information filtering in the WWW context - adaptive IR systems with Web or hypermedia interfaces - intelligent tutoring systems on the WWW - Web recommender systems - personalized Web sites and services - adaptive Web-based collaboration systems - adaptive natural language generation in hypermedia and Web contexts - adaptive navigation support in large hyperspaces - adaptive presentation of non-textual content - empirical studies of adaptive hypermedia and adaptive Web-based systems - Web data mining for personalization and adaptivity - personalization and adaptivity in E-commerce - user modeling in Web-based applications - intelligent Web agents for personalization and adaptivity - distributed adaptive applications on the WWW - acquisition and management of user models on the WWW - security and privacy aspects of user models on the WWW - methods, techniques, and tools for user modeling - Web metadata as a basis for user modeling - dealing with changing interests and preferences of Web users - user interfaces for all - usability aspects of adaptivity - Web servers for user models/profiles
