Talk 1: Explaining Recommendations in time-aware Location-based Social Networks
Prof. Yannis ManolopoulosAristotle University of Thessaloniki, Greece
Online Social Networks have attracted lots of users’ attention in the last decade. Recommendation services constitute a critical functionality of such social platforms: users receive recommendations about resources (documents, pieces of music) and potential friends (people with the same interests). Recently, technological progressions in smart phones enabled the exploitation of geographical data information in social networks. Users can now receive recommendations about new Points of Interest (POIs), and new activities in POIs. Eventually, Location-based Social Networks (LBSNs) may become the “Next Big Thing” of the Internet industry. This talk surveys the related work and current state-of-the-art in recommenders systems for LBSNs. We also provide a time-aware perspective in LBSNs and we present the explanation styles used for the recommendations. Specifically, we represent the latest work in LBSNs by comparing algorithms and real systems and by categorizing them in multiple ways. Through this survey, we bring to surface the shortcomings and new prospects of LBSNs.

Talk 2: Ecosystem of CNRTA in Brazil
Dr. Silvio A. SpinellaInformation Technology Center Renato Archer, Brazil
The Brazilian Government Plan “Living without Limit” was established in November 2011 with the purpose of ensuring the full and equal rights of persons with disabilities. The plan involves the participation of 15 ministries, and its actions are distributed in four main areas: Health Care, Access to Education, Social Inclusion and Accessibility. Initiatives regard to Assistive Technology belong to the axis of Accessibility, and, among them, there is the implementation of CNRTA (National Reference Center for Assistive Technology), which is linked to the Center for Information Technology Renato Archer (CTI). The purpose of this presentation is to introduce aspects about this plan and to show some actions that CTI, with support from the Ministry of Science, Technology and Innovation (MCTI), has done in order to manage the ecosystem created by CNRTA and their associated TA cells spread along Brazil. As a result, opportunities for cooperation with Research Institutions of European Community in the area of Accessibility are expected.
