Call for Papers User Modeling and User-Adapted Interaction: The Journal of Personalization Research Special Issue on User Modeling for Web and Hypermedia Information Retrieval (In honor of James Chen) Deadline: February 25, 2002 Information Retrieval is one of the oldest application areas that utilized user profiles and user models to serve individual users better. Yet Information Retrieval is not the same research field now that it was just 5-6 years ago. The World Wide Web has challenged classic models and approaches of Information Retrieval and brought to life a large stream of research on Web Information Retrieval that differs from traditional document retrieval in several ways. To encourage researchers to report on the application of user models for Web and Hypermedia Information Retrieval, we are calling for contributions to a special issue of UMUAI. In the past, UMUAI has hosted special issues on adaptive information retrieval and adaptive hypermedia. The goal of the new special issue is different -- to show the benefits and challenges of user modeling and personalization for Information Retrieval in the context of Hypermedia and the Web. This special issue will serve as an essential reference for researchers on Web Information Retrieval who are interested in making their systems adaptive and personalized. We want to devote this special issue to the memory of James Chen, a researcher who contributed to several foundational projects at the crossroads of adaptive hypermedia and information retrieval, reported in UMUAI (1). James has tragically died in an accident in 2001, but his work keeps inspiring other researchers. For this special issue we will consider all works devoted to user modeling and user-adaptive systems in the field of Web and hypermedia information retrieval. Relevant topics include, but are not limited to: o adaptive information retrieval in a hyperspace of interconnected documents o building and maintaining user models and profiles for Web information retrieval o agent architectures for personalized Web information retrieval o personalized Web information services o personalized information services for corporate and knowledge management portals o merging search and browsing in adaptive information retrieval o adaptive hypermedia techniques in information retrieval context o empirical evaluation of adaptive Web information retrieval systems o adaptive visualization for Web information retrieval o group user models, collaborative filtering, and social navigation for Web information retrieval o user modeling and personalization for digital libraries o Web and Hypermedia Information Retrieval through mobile devices About UMUAI The journal User Modeling and User-Adapted Interaction is an archival journal that publishes mature and substantiated research results on the (dynamic) adaptation of computer systems to their human users, and the role that the system's model of the user plays in this context. Papers that present untested research ideas are not ready to be submitted to UMUAI. Instead, these ideas should first be presented at workshops to get feedback from colleagues. Once you can demonstrate ideas that are backed up by results, then they are ready for UMUAI. These results may be generated by building a (partial) computer implementation and from that, either analyze its behavior, run empirical experiments, or analyze the idea using formal means. Many articles in UMUAI are therefore quite comprehensive and describe the results of several years of work. Consequently, UMUAI gives "unlimited" space to authors (as long as what they write is important) and also does not mind if research that is being submitted to UMUAI has been previously published in bits and pieces at workshops and conferences (as long as the synthesis provides significant new insights). Important Dates January 30, 2002 (Recommended) Submit a one page abstract to guest editors February 25, 2002 Deadline for submission of full papers May 1, 2002 Notice of review results Abstracts of one page or less should be sent to the guest editors prior to January 30 2001, especially if authors are concerned about relevance of the paper to the special issue. Abstracts are highly encouraged, but not required. These abstracts will be reviewed by the guest editors only. Full paper submissions should be in the UMUAI format and will be reviewed both by the guest editors and by two or more other UMUAI reviewers. More details of submission formats are available from UMUAI's web site, http://www.informatik.uni-essen.de/UMUAI.
