                            CALL FOR PAPERS

                International ICDM Workshop on Data Mining
                     in Web 2.0 Environments (Web2DM)

               http://www.kde.cs.uni-kassel.de/ws/Web2DM

             held in conjunction with the IEEE International
                 Conference on Data Mining (ICDM 2007)
               on October 28, 2007 in Omaha, United States.

=========================================================================
Topics of interest:

Users feel very attracted by currently emerging Web 2.0 environments,
that allow to provide content in a simple, unrestricted, and ad hoc way.
Providing annotations (such as tags) in a Web 2.0 like way is applicable
to a wide range of resources and data types, such as web pages, images,
multimedia, etc. There is, however, a disadvantage: the freedom to
provide arbitrary (personal) content and tags in ubiquitous,
uncoordinated ways results in very large amounts of poorly structured
information. Behind the current hype around Web 2.0 applications, this
raises several important challenges for future data and web mining
methods.

The workshop aims to bring together researchers and professionals in the
areas of data and web mining, information systems and collaborative
systems to discuss challenges and solutions of applying data mining to
highly unstructured, user created data. Such challenges include the
analysis of loosely-coupled snippets of information, such as overlapping
tag structures, homonym or synonym tags, blog networks etc. Other
challenges arise from scalability issues or new forms of fraud and spam.
They demand, for instance, innovative methods of tag clustering,
filtering, aggregation, personalization and visualization.

As an outcome of the workshop, we expect a better understanding of
methods which can be successfully applied to Web 2.0 applications and
open challenges yet to be solved.

Topics of interest include but are not limited to:

• analysis of blogs
• tag clustering and visualization
• synonym and homonym resolution in tags
• visual and textual information extraction
• temporal analysis
• data streams, trend detection, and concept drift
• application of web and text mining to wiki content
• discovering social structures and communities
• evolution of online social networks
• predicting user behavior
• analysis of dynamic networks
• discovering misuse and fraud
• combining the web with data from other sources, mining with mashups
• deriving profiles from usage
• personalized delivery of information
• applications, case studies
