CALL FOR PAPERS Special Topic Issue on Management of uncertainty and imprecision in multimedia information systems. in International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems (IJUFKS<) Aim: The diffusion of the Internet and the consequent increase in the production and exchange of multimedia information demand the development of effective systems for information access. The main aim of these systems is to provide a fast and effective identification of the information relevant to specific users' needs; this is a complex decision making task, pervaded with vagueness and uncertainty, due to the fact that it requires an interpretation of both the users information needs and the stored information. A promising direction to make effective the information access is to model the uncertainty and vagueness intrinsic in the processof identifying relevant information, and to make the systems adaptive, i.e. able to learn the users concept of relevance. TOPICS OF INTEREST We invite submissions of papers on the use of Soft Computing techniques for modelling the uncertainty, vagueness, subjectivity, and learning in information access. Specific topics of interest include, but are not limited to the following: Information retrieval, Database management, Multimedia indexing and retrieval,Information Filtering, Multilingual information access, Collaborative filtering, Text Categorization,Digital Libraries, Text Mining. Where the information access process is modelled and/or managed using Soft Computing techniques, like for example : fuzzy logic, probabilistic reasoning, multi-valued logics, chaotic computing, belief networks, machine learning, rough sets, possibility theory, neural networks. Papers due: January 31st, 2002. Please send your intention of submission SUBMISSION PROCESS: Submissions papers can be: (i) either, full length papers reporting original work generally of up to 4000 words; (ii) or, brief communications of original work or work in progress of up to 1200 words.
