We are pleased to announce the first International Workshop on Social Personalisation co-located with the 25th ACM Conference on Hypertext and Social Media, 1–4 Sep 2014, Santiago, Chile.
For the Social Personalization workshop, we aim to attract researchers from all over the world working in the fields of User Modeling, Personalization and Recommendations where the social context plays a fundamental role. This topic is important because it involves leveraging new sources of information that are specific for social systems such as shared items and tags, user public profiles, social connections, and logs of user social activities in order to improve people's information access in a wide variety of tasks and across different devices. These social information sources offer social personalization systems a chance to compensate for the lack of information and structure that is used by traditional personalization technologies ranging from recommender systems to E-learning.
Thus, we invite submissions which may include the following topics, but are not limited to:
The goal of this workshop is to share and discuss research that goes hopefully beyond classic personalization techniques, trying to capitalise potentially useful information available in social data for paving the way to more efficient personalized information access technologies.

9:15-10:30: Keynote - Nuanced graph representation to improve recommendation: the case of browsing and social networks by Luca Aiello.
Abstract: Graphs are ubiquitous representations of a wide range of online traces generated by user activities including browsing, messaging, social linking, and many more. For their simplicity and power, graphs (like other similar representations of relational data) have been used in a plethora of applications, most of them falling under the umbrella of recommendation and personalization. However, very often the notion of graph and its atomic components (nodes and edges) are adopted uncritically, without giving much thought to their nature or meaning. In real-world scenarios the meaning of a link can vary broadly even within the same system or interaction type. We study browsing and social graph and show how a to obtain a more nuanced representation of their links to help gaining a deeper understanding of their nature and, in turn, to properly exploit the information about link type in recommendation tasks. First, we present the use of the BrowseGraph and its decomposition into ReferrerGraphs for image and news recommendation. Last, we will show how conversation graphs can be decomposed in subgraphs carrying different information about the type of resources exchanged between peers, providing an overview on the potential that such nuanced representation can have in the field of recommendation. Our analysis is conducted on large datasets extracted from Yahoo News, Flickr, and aNobii.
Bio: Luca Aiello received his Ph.D. in Computer Science from the University of Torino, Italy in 2012. He is currently a Research Scientist at Yahoo Labs in Barcelona. He conducts interdisciplinary work connecting computer science, physics of complex systems, and computational social science through quantitative big data analysis. Recently his research has been devoted to study social phenomena such as homophily, influence, conversational norms, status and social attention, with applications to personalization, ranking, recommendation and link prediction. He is General Chair for the SocInfo’14 conference and organizer of the SNOW’14 Workshop. He has been member of the PC of major computer science conferences, including WWW, WSDM, ICWSM, CIKM, ACM MM. He is leading the work of Yahoo in the SocialSensor EU project consortium.
