First International Workshop on Web Computing in Cyberworlds (WCCW2004) http://cse.seu.edu.cn/people/bwxu/wccw2004 in conjunction with 2004 International Conference on Cyberworlds (CW2004) Tokyo, November 18-20, 2004 http://cw2004.myvnc.com/ 1. Aims The open approach to developing Web computing in Cyberworlds has attracted an increasing attention in both academia and industry. This workshop will not only focus on architecture and models for Web computing, but also emphasize the emerging technologies in various Web computing aspects, which will be held together with the International Conference on Cyberworlds 2004 (http://cw2004.myvnc.com/). The Web Computing is an ideal model to utilize the millions of personal computersâ idle CPUs through the Web, thus providing high efficient and cheap computation. The distributed and dynamic architecture and system models have become the foundation of Web Computing. The inherent cooperation in Web computing enables a large range of computations. The aim of this workshop is to bring together researchers and practitioners working on theory, techniques and applications, concerning analysis and/or manipulation of Web computing. The complex and large-scale Web computing requires effective methodologies and tools for the analysis, design, implementation and maintenance. 2. Topics The workshop emphasizes on the analysis and manipulation techniques. Topics include, but not limited to: l Architecture and Models - Web Computing Model and Framework - Web Computing Software Environment - Heterogeneity and Portability in Web Computing - Semantics and Ontology Engineering l Methods and Tools - Web Computing and Distributed Technologies - Security and Accessibility in Web Computing - Proxy and Cache Techniques - Neural Networks, Fuzzy Logic, Rough Sets, and Evolutionary Computation l Applications - Applications of Web Computing - Web Information Filtering and Retrieval - Clustering-Based Recommended Systems - Web-Based Applications and Systems l Quality Assurance - Cooperation and Integration - Testing and evolution - Maintenances of Web Computing Systems 3. Submission Original papers on new results in the rapidly emerging area ö web computing in Cyberworlds are welcome. Papers should indicate the innovative aspects of the results and contribution to the field. Papers submitted for publication in a journal or another conference will not be considered. The format of submitted papers must follow the IEEE conference proceedings guidelines which are available at http://computer.org/author/ psguide.htm. All submitted papers will be evaluated according to its originality, significance, correctness, presentation and relevance. Papers must be submitted electronically in Postscript or PDF format via E-mail to professor Baowen Xu (firstname.lastname@example.org). All accepted papers will be published in the proceedings of the 2004 International Conference on Cyberworlds (CW2004) published by IEEE Computer Society Press.
