Santos, C., Pedro, L. (2010). In Personal Learning Environments and Personal Learning Networks. Canada: Athabasca University and National Research Council of Canada.
Abstract: The present chapter addresses the conceptualization and development of an integrated Web 2.0 platform and institutionally supported Personal Learning Environment (PLE) for Higher Education – the SAPO Campus project. Depicted as a social media platform for Higher Education, the SAPO Campus project is described in its various facets, services and relationships with other entities, making a case for user-generated content production and aggregation for use in Higher Education. Taking as a starting point the current technological context inside Higher Education Institutions, this chapter presents the initial conceptual model, system architecture and technological framework to promote the SAPO Campus Open and Social Learning objective. Preliminary data obtained from early adopters’ use of the platform is discussed and a new conceptual model – one that aims to promote an Open and Social University framework – is put forward.

Abstract: In recent years, social media services have become a global phenomenon on the Internet. The popularity of these services provides an opportunity to study the characteristics of online social networks and the communities that emerge in them. This paper presents an analysis of the users’ interactions in the implicit network derived from tweet replies of a specific dataset obtained from a popular microblogging service, Twitter1. We analyze the influence of the topics of the tweet messages on the interaction among users, to determine if the social aspect prevails over the topic in the moment of interaction. Thus, the main goal of this paper is to investigate if people selectively choose whom to reply to based on the topic or, otherwise, if they reply to anyone about anything. We found that the social aspect predominantly conditions users’ interactions. For users…

Abstract: This paper presents an initial attempt to use micro-blogging messages posted on Twitter (by users in transit) to perform real-time sensing of traffic-related information. We propose a text classification approach to the problem: we wish to automatically identify traffic-related messages posted on Twitter, among the millions of unrelated messages posted by users. Given that the fraction of relevant traffic messages on Twitter is extremely low (< 0.05%), the main challenges involved at this stage are (i) creating a suitable training set for setting up the classifier, and (ii) driving the classifier to a reasonable level of precision in identifying relevant messages. We opted for a dual-stage bootstrapping strategy for tackling both these problems simultaneously. First, we used short message reports that are automatically posted on Twitter …

Abstract: The automatic processing of microblogging messages may be problematic, even in the case of very elementary operations such as tokenization. The problems arise from the use of non-standard language, including media-specific words (e.g. “2day”, “gr8”, “tl;dr”, “loool”), emoticons (e.g. “(ò_ó)”, “(=ˆ-ˆ=)”), non-standard letter casing (e.g. “dr. Fred”) and unusual punctuation (e.g. “…. ..”, “!??!!!?”, “„,”). Additionally, spelling errors are abundant (e.g. “I;m”), and we can frequently find more than one language (with different tokenization requirements) in the same short message. For being efficient in such environment, manually-developed rule-based tokenizer systems have to deal with many conditions and exceptions, which makes them difficult to build and maintain. We present a text classification approach for tokenizing Twitter messages, which address…
Perante a mudança revolucionária nos estilos de desenvolvimento de novos produtos e a crescente substituição das metodologias tradicionais por metodologias ágeis, surge com a presente investigação um espaço e tempo para compreender a adequação da gestão ágil de projectos ao cenário do desenvolvimento de produtos multimédia. Esta investigação foi sustentada por um estudo de caso focado num cenário académico, o Laboratório SAPO/UA, mais concretamente no projecto SAPO Campus. A dinâmica de funcionamento deste cenário, presentemente debilitada quanto a processos e práticas de gestão, foi analisada com vista à posterior elaboração de um modelo ágil de gestão de projectos. O modelo concebido foi implementado num grupo restrito de membros da equipa de projecto e posteriormente validado. Como resultado, espera-se uma melhoria efectiva do funcionamento do projecto, bem como uma reunião de argumentos que fortifiquem uma perspectiva clara acerca da adaptação da gestão ágil de projectos ao cenário da produção multimédia.

Abstract: The study of the blogosphere can provide sociologically rel- evant data. We analyze the links between blogs in the por- tuguese blogosphere, in order to understand how they group and interact, to identify clusters and to characterize them. Our data set contains post data for more than 70,000 blogs, with over 400,000 links. The linkage data is represented as a blog graph and partitioned into several slices, according to their in-degree. We then study the evolution of blog fea- tures, and observe a consistent pattern of decrease in posting frequency, number of out-links, and post length, as we move from the highly-cited blogs to the less cited ones.

Abstract: The Post-Industrial era in which we live reveals how the media institutions have changed in regard to children. The number of software applications directed and vehiculated towards them, essentially by new media, creates an impact on educators who interact with children and with parents who respond to a child’s decision-making capacities and influential abilities. It is fascinating to verify how adults are pleased and willing to learn from children. It should be noted that in Portugal 61% of households with children have two or more computers, 39% of Portuguese children between the ages 4 and 5 use the internet regularly, 67% of children between the ages 6 and 7 use computers on a daily basis and 78% of children ages 8 or 9 and up, use the computer on a regular basis. One of these software applications, available for free, is called Scratch, created by Mitchel Resnick, Professor at MIT, who recognizes the new children’s status, regarding the process of communicative, reflective, creative and playful child co-participation. This application was translated into Portuguese and made available in Portugal by Portal SAPO Kids, which belongs to the company Portugal Telecom.

Abstract: The ludic potential of programming with Scratch engages children in active participation where they learn to problem-solve, create and recreate projects by simply playing. Children are therefore able to learn how to think creatively, to express themselves clearly, to analyze systematically, to be fluent in the use of IT programming – which is an important contribute towards literacy in the 21st Century – to build iterative development processes, to put in practice metacommunication and to promote cooperation between children and adults.

This paper describes the specification and design of a field trial for a Social TV application. The field trial was designed to be carried out over a commercial IPTV service relying on actual customers to whom the application is offered. Social TV Games along with questionnaires, diaries, logs, direct observation and interviews are among the methods adopted to gather data related with user experience and integration of social features in the current IPTV experience.

Abstract: Integrating social networks in an IPTV recommender system, In WS “Future Television: Integrating the Social and Semantic Web”, integrated on the 8th international interactive Conference on interactive Tv&Video (Tampere, Finland, June 09 – 11, 2010). EuroITV ’10.
The proliferation of multiple channels in the actual offer of cable and IPTV services is bringing challenges for users when selecting which program to see. Recommender systems are being introduced with the goal of facilitating the viewers’ choices and promote TV content consumption. Different technical approaches to these systems are supported either on automatic algorithms or social data and activities analysis. This paper reports on the first development phase of the Pétala system – a recommender system for an IPTV Telco – that aims to improve content recommendation by integrating social networks. Pétala provides the ability to use the system both in the Set-top box or as a web widget integrated in a social network like Facebook.
