Call for Papers  
Personalization, Policy and Usability Issues on the Semantic Web Workshop

One-day workshop
to be held at the 4th European Semantic Web Conference

June 6 or 7th, 2007
Innsbruck, Austria

Deadline Extension: Paper submission until April 10th, 2007!

One of the main aims of the Semantic Web is to bring the Web closer to the needs of people. Though there is a great amount of commonality of these needs for many people (for instance, to get the meaning of Web information) these needs may also be quite different for different groups of users and for single persons. Personalization aims at tailoring of Web content and Web service functionality to these different needs. Policy allows people to adapt their interaction with the Web to their needs. Usability aims to optimize how people with their differing personal goals, skills, and policies can interact with systems in an optimal way. Research in security and privacy is more and more concerned with making end users aware about policy and security issues. Even the most powerful security mechanisms would be ineffective if users were not able to personalize their policies, balancing protection and functionality as appropriate to their needs. End users should be able to verify and validate their policies. This is especially important on a Semantic Web with its much more complex interaction capabilities between users and systems and between systems. Accordingly, user awareness and user empowering are key issues in FP7, the 7th European Research Framework.

The main issues in this context can be outlined as follows:
  • focus the Web content on those aspects which are relevant for the user depending on the concrete user and the context;
  • provide content and services in a way which is adapted to the needs and capabilities of the user;
  • support of personalized policies allowing the user to control the way s/he can interact with other people and services through the Web; and
  • design system interactions for optimal usability taking the relevant personalization and policy issues into account.

This workshop will bring together researchers and practitioners from various fields like security and privacy methodologies, HCI methodologies, user modeling, (controlled) natural language processing, personalization techniques, automated reasoning, and the emerging discipline of security engineering. The workshop is organized along three topical foci: Semantic Web-enabling Technologies for Personalization, Semantic-based Content Personalization in Ubiquitous Environments, and usability evaluation of Web applications with special focus on user modelling, personalization and policy specification.

For the workshop, we expect submissions to discuss especially some of the following topics:
  • user modelling: techniques and models
  • user and system interaction models for personalization, policy specification, and usability evaluation
  • Acquisition and application of user profiles for usability evaluation
  • Ontology alignment and evolution for user modeling
  • User-aware querying in the Semantic Web
  • rust, privacy and transparency in the personalization process
  • Semantic Web Services and Service-oriented architectures for personalization
  • Semantically enriched user models for ubiquitous and mobile environments
  • Social filtering (collaborative filtering) exploiting content semantics
  • Hybrid filtering technologies using content semantics
  • How to use semantics for preference description

Furthermore, submissions about best practices and applications are greatly appreciated, discussing e.g.:
  • Needs: scenarios where personalization brings benefits
  • Experiences: lessons learnt from previous research
  • Solutions: for personalized access to content in a Semantic Web
