With the explosion of the volume of available information on the Web, the information retrieval systems (IRSs) have become necessary to help the users to find relevant documents. Traditional IRSs may be drastically different if they may take into account the context of the information and the context of the query. Contextual information includes both explicit and implicit knowledge about intentions of the user, environment the user is attached to and the system itself. Such factors constrain the search without intervening in it explicitly. One idea to improve the efficiency of IRSs is to make explicit the contextual information in order to enhance the retrieval performance. The workshop audience is intended to explore related work, theoretical framework and applications which focus on contextual IRSs. It is intended for researchers in the area of computer science, information retrieval, and digital libraries. The workshop's aim is to promote exchanges in these fields, to establish the current state of the art, to identify the emerging problems and to propose future research directions. Besides, we encourage interested researchers from related areas to attend the workshop. Relevant topics include but are not limited to: § Contextual information retrieval modeling § Contextual information retrieval metrics and assessments § Use of contextual graph to model information retrieval systems § Theory in context and information retrieval § Multiple contexts in information retrieval § Adaptive and interactive information retrieval § Multi-context based browsing § Use of ontology and thesaurus to contextualize the querying and indexing § Querying contextual information retrieval systems § Experiments with test collection of contextual information retrieval systems § Tools to support contextual information retrieval Papers and Evaluations Authors are invited to submit electronically original papers through the CONTEXT’05 web site, http://www.context-05.org. Papers should be single-spaced with a font size of 11. Two types of papers are solicited: full paper : 8-12 pages short paper: 4-6 pages The organizers will oversee a peer-review process for all the submitted papers. Selection will be based on originality, clarity, and technical quality. A synopsis of the presentations and discussions will be posted on the workshop web page. Revised versions of research papers will appear in the CEUR Workshops Proceedings (http://ceur-ws.org). At least one author of each paper should attend the workshop to present the paper. For more information, please contact the workshop chairs. Please send all submissions to workshop chairs at: Bich-Lien.Doan@supelec.fr Key dates Submissions due: March 31, 2005 Acceptance notification: April 15th, 2005 Camera-ready papers received: April 30th, 2005 Program on line: May 5th, 2005 Workshop: July 5th, 2005
