Title: Using context models and models for contextually instantiated social relations for mobile social computing services
Abstract:
Social network analysis and models for social structures have gained substantial interest in connection with Web 2.0, communities and other social computing paradigms. While numerous platforms provide means to manage personal social networks of simple kinds, few approaches have been investigated that aim at modelling instantiations of social relations and subsequently using these models for services which are socially- AND context-aware at the same time. In contrast to the simple models of relations which always represent an average with respect to contextual parameters such as time and space, we will investigate models for describing the instantiations of these relations in time and space and discuss ideas for heuristic methods for identifying these instantiated relations algorithmically. These models can be used for a broad spectrum of context-aware mobile services in the fields of Contextual Social Awareness, Contextual Social Recommenders and Information Exchange as well as Context-sensitive Authorization and we will suggest ideas of how such services can be designed to effectively use instantiated social relation models.

Objectives Top

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.
