Objectives & Topics:
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.

We invite submissions that may include the following topics, but are not limited to:
* search and recommendations based on social links
* search and recommendations in collaborative tagging systems
* group-level search personalization
* search and recommendations in blogs and microblogs
* approaches for social personalization in recommender systems
* approaches on personalized social collaboration
* approaches on social linking
* methods for social search and navigation
* methods for social predictive models
* social methods for information visualization and display
* applications of the aforementioned topics to diverse domains 
* any other methods that exploit new forms of social data for search and personalization
* applications of any of the above methods and technologies

The goal of this workshop is to share and discuss research that goes hopefully beyond classic personalization techniques, trying to capitalize potentially useful information available in social data for paving the way to more efficient personalized information access technologies. In addition to personalization, we also consider social search and navigation as topics that involve the importance of the social dimension on filtering and information access.

We solicit regular research papers (up to 6 pages) & short papers (up to 2 pages), both in the ACM conference paper style. Papers should be submitted in EasyChair to https://easychair.org/conferences/?conf=sps2015

Submission guidelines: 
All submitted papers must be written in English;
* contain author names, affiliations, and email addresses;
* be formatted according to the ACM SIG Proceedings template (http://www.acm.org/sigs/publications/proceedings-templates) with a font size no smaller than 9pt;
* be in PDF (make sure that the PDF can be viewed on any platform), and formatted for US Letter size;

All papers will be peer-reviewed, must not be under review in any other conference, workshop or journal (at the time of submission), and must contain novel contributions. Accepted papers will be published according to the ACM SIGIR 2015 WS publication rules.

SPS 2015 will take place at: Campus “Casa Central” of Pontifical Catholic University of Chile (PUC Chile) and will be held in conjunction with the 38th Annual ACM SIGIR Conference. This campus is located in Av. Alameda 340, in Santiago Downtown, Chile.
