International Workshop on Social Personalization & Search (SPS2015)

For the Social Personalization & Search workshop, we invite to participate researchers working in the fields of Information Retrieval, Personalization, User Modeling, and Recommender Systems where the social dimension plays a fundamental role. The workshop is examining several approaches that leverage the social side of the search process on two main contexts: (a) using social data for improving search and recommendations, and (b) search as a social process, collaborative IR.

On the first context, we expect to attract contributions that use the social dimension in different methods for personalization and search, such as data from online social networks, social tagging systems, online forums and community-based Q&A. This topic is important because it involves leveraging new sources of information that are specific to social systems such as shared items and tags, user public profiles, online and offline social connections, and logs of user social activities in order to improve people's information access in a wide variety of tasks and devices.

On the second context, the social dimension is emphasized as collaboration, so we aim to discuss works that consider information seeking as a collaborative activity. Here, researches can potentially use explicit social communication information (such as online, offline chat) to boost the personalized search experience for each user, or in a community-wise sense, support the common goal of users working on the same search tasks, such as people planning a group trip.
