Scope
The Web is voluminous, dynamic, information and data intensive, and varies from completely unstructured to fully structured. Despite this Web chaos, all sectors of our global society use the World Wide Web to further such goals as electronic commerce, information acquisition, and information dissemination. How can we harness this vast mass of potential information to further these and other similar goals?

In this workshop, we propose to explore ways we can apply conceptual modeling to address these challenges. In particular, we wish to consider building conceptual data models to describe knowledge about patterns of data, about objects in our models, and about interactions among these objects and with Web users. These conceptual models should provide the basis for high-quality organization, presentation, search, information extraction, intelligent caching, electronic business processing, and Web site development and management.

WCM2000 follows a very successful WWWCM'99 (proceedings published in Advances in Conceptual Modeling, Lecture Notes in Computer Science, vol. 1727, Springer-Verlag, 1999), and we hope to build on the accomplishments of the first workshop.

Topics
We invite submissions on all topics relating to conceptual modeling and its application to the Web. Particular topics of interest include:

• data and behavioral semantics
• data caching
• data cleaning
• data extraction and information retrieval
• data integration
• data models for Web data
• knowledge discovery
• mining text and data
• semantic search
• semi-structured data
• site design and management
• standards for Web data management (XML, RDF, ...)
• view creation and maintenance
• visualizing the Web
• Web database development
• Web query languages
• Web warehousing
• Web security
• workflow modeling

We are interested in conceptual modeling applied to Web tools, such as:

• authoring tools
• browsers
• mediators
• spiders
• wrappers

Web applications that use conceptual modeling are also of interest:

• digital libraries
• e-business
• e-commerce
• Web publishing

Any other topic providing insight into opportunities for conceptual-modeling research on the Web is also welcome.

Publication
Accepted papers will appear in a workshop proceedings, published by Springer Verlag. Authors will present their work and provide an opportunity for workshop participants to discuss topics related their work. Papers not selected for publication may be invited for presentation as posters or as work in progress.

Important Dates

• Electronic submission of abstracts: 14 April 2000
• Electronic submission of full papers: 21 April 2000
• Notification: 16 June 2000
• Camera-ready copies due: 11 July 2000
