                   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

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


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,
