\___  Objectives

Many Web 2.0 applications have rapidly emerged on the Web. This
indicates a currently ongoing grass-root creation of knowledge spaces on
the Web. The reason for the apparent success of the upcoming tools for
Web cooperation (wikis, blogs, etc.) and resource sharing (social
bookmark systems, photo sharing systems, etc.) lies mainly in the fact
that no specific skills are needed for publishing and editing. As these
systems grow larger, however, the users feel the need for more structure
for better organizing their resources. For instance, approaches for
tagging tags, or for bundling them, are currently discussed on the
corresponding news groups. Furthermore, recent developments show an
increasing trend for Web 2.0 applications to become ?ubiquitous? also
beyond the Web; in particular, Web and mobile usage interfaces to social
platforms are increasingly being combined. 

The machine learning community has a long tradition in extracting
structure from large scale data collections. With the Web 2.0, it faces
(at least) three new challenges:
	1. New data types appear, for which there exist currently no
out-of-the-box data mining solutions, for instance for the triadic
hypergraph structure of folksonomies or for documents in wikis that
permanently change over time.
	2.The majority of Web 2.0 users have no skills in knowledge
engineering and data mining. Tool support targeted directly at the end
user has thus to hide the complexity usually involved in the different
data mining steps (eg, data cleaning, parameter settings). 
	3. Mobile Web 2.0 applications have the potential to offer huge
amounts of different types of data: localization is added to
temporalization. 

Beside submissions that address one of these challenges, papers
discussing other aspects on the intersection of Web 2.0 and Knowledge
Discovery are also highly welcome.


\___  Topics of Interest 

Topics of interest include but are not limited to:

    * network analysis of social resources sharing systems
    * analysis of wikis and blogs
    * analysis of social online communities
    * discovering social structures and communities
    * analysis of network dynamics
    * discovering misuse and fraud
    * web 2.0 personalization
    * web 2.0 technologies for recommender systems
    * information retrieval in the web 2.0
    * community detection
    * emergent semantics
    * web 2.0 based ontology learning
    * predicting trends and user behavior
    * semantic association identification by link analysis
    * web 2.0 crawling
    * mining information from distributed and re-combined (?mashed-up?)
Web 2.0 sources
    * mobile Web 2.0: social search; mobile communities; ?
    * usage interfaces for mining: parallelization of Web and mobile
interfaces; mash-up interfaces; interactions between usage interfaces
and data collection, mining, and presentation 
    * privacy challenges in Web 2.0 and mobile Web 2.0 applications
    * applications of any of the above methods and technologies
    * ...

We also encourage submissions which relate research results from other
areas to the workshop topics.
