Nowadays, numerous Web applications rely on implicitly or explicitly collected data on their users and their behavior in order to provide adapted and personalized contents and services. As these applications become increasingly connected, a major challenge is to allow various applications to exchange, reuse, and integrate their data and user models, hence, to allow for user modeling and personalization across application boundaries. A great body of Semantic Web research on the use of well-defined standards, vocabularies, and ontologies is currently being adopted to provide extensibility, flexibility, interoperability, and reusability.

On the one hand, the ability of exchanging, reusing, and integrating the user models allows applications to enhance and broaden their user models with additional data. On the other hand, it helps users to get the content and services that suit their needs and situations and to syndicate these services in so-called mash-ups. This type of open-world user modeling poses several challenges to the Semantic Web community:

* How can Semantic Web technology be employed to cope with semantic and syntactic heterogeneity in user modeling?
* How can personalization and user modeling techniques be beneficial for Semantic Web systems?

This workshop aims to bring together academic and industrial researchers and practitioners in the fields of Semantic Web, user modeling, and personalization in order to discuss theoretical and practical knowledge, open research issues, applications, and experiences for common benefit.

Topics

The workshop will tackle challenges posed by linking user data and applications, including, but not limited to, the following themes:

* User modeling and personalization in the Semantic Web
* Aggregation and integration of distributed user data/profiles
* Linking data on the Social Web
* Semantic Mashups linking applications
* Techniques for connecting distributed user-generated data
* Methods for exchanging user data
* Intertwining social networking services
* Studies assessing the use of external/public user data for personalization
* Applications demonstrating intermixing of user profiles from different sources

This workshop aims to bring together academic and industrial researchers and practitioners in the fields of Semantic Web, user modeling, and personalization in order to discuss theoretical and practical knowledge, open research issues, applications, and experiences for common benefit.
