  Ecossistema Integrado para Educação Digital, Descrição: The objective of this project is to research and develop a point-to-point reference system for digital education. The project envisions the development of tools for Ambient Intelligence in digital education that contribute to: better understand the educational environment in a classroom, reduce the educator's work time and provide a decision-support and recommendation system for continuous improvement in students' learning. We will build upon existing technology for digital education, creating innovative models for learning analytics, to infer the context and learning profile of students, intelligent models for recommandation of personalized education content. The solution is composed of four lines of research and development: (i) an interface for the publicationand classification of learning objects. (ii) an intelligent content composer for creating lessons from digital learning objects. (iii) intelligent education material, with a delivery app instrumented to register every action the user performs, analysis methods for this data and automatic adjustment of the content to personalize it to the student's context. (iv) Multi-modal models of learning analytics. These packages are built with innovative methods of data analysis, content recommender systems and activity recognition. The project encompasses interdisciplinary research, requiring a combination of social computing, ambient intelligent, data mining, learning analytics and others. It is necessary to research and develop new models for classifying and understanding individuals' behaviour and behaviour in a group in a learning context, based on data from usage data, ambient sensors, camera images, assessment results, and new devices capable of collecting human signals. In addition, the project promotes the ecosystem for development for Samsung devices, through its intimate connection to Samsung technoloy, as well as contributing directly to R&D in the country.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Andrew Koster - Integrante / Fernando Koch - Coordenador / Allysson Oliveira - Integrante / Tiago Primo - Integrante.

  Community-Building Information Technology, Descrição: Creating software applications that foster web-based social interaction is still very hard and currently beyond the capabilities of end-users, since highly skilled web application developers are needed. Consequently, the cost of community formation and evolution beyond those based on simple, general and stable interaction patterns is still too high. Individuals, however, looking either for new, partially formed, or already standing communities whose interactions are much more domain specific and specialised need software tools and platforms that support the formation of and the adjustment to communities, as well as the adaptation to new, perhaps dynamically evolving, events during a community?s lifespan. CBIT aims at transcending the current level of social software applications and platforms for community building into the meta-level for which today?s applications will arise as particular instances. For this we shall approach community building as an iterative process consisting of community formation, interaction, and growth. In CBIT a community is understood as a group of peers whose interactions are defined via agreements on social contracts on behaviour, meaning, and reliability, and represented in a community charter. Consequently, community building will be subject to the mechanisms to be developed in the scope of this project for charter specification and selection, charter grounding and enactment, and charter revision and modification. To concretise this approach, we shall realise it for a community-building process that fosters collaboration in the generation of digital educational contents.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Andrew Koster - Coordenador / Marco Schorlemmer - Integrante., Financiador(es): Ministerio de Ciencia e Innovación - Outra.

  Agreement Technlologies, Descrição: This project proposes a new paradigm for next generation distributed systems. The new paradigm will be structured around the concept of agreement between computational agents. These agreements must be consistent with the normative context where they are established and will permit, once accepted, that the agents call for mutual services and honour them. An entity, by the fact of being autonomous, may choose whether to fulfil an agreement or not, and it should fulfil them when there is an obligation to do so derived from the standing agreements. Autonomy, interaction, mobility and openness are the characteristics that the paradigm will cover from a theoretical and practical perspective. Semantic alignment, negotiation, argumentation, virtual organizations, learning, real time, and several other technologies will be in the sandbox to define, specify and verify such systems. Both functional and non-functional properties will be studied. Security on execution will be based on trust and reputation measures. These measures will help in the decision making of the agents to determine with whom to interact and what terms and conditions to accept. Virtual worlds technology will be explored to give high usability to the tools. Scalability will be guaranteed by the design of new algorithms for semantic alignment and through the use of electronic institutions. The project will also build algorithms, software platforms and three demonstrators on electronic procurement, mobile health and water conflict resolution.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Andrew Koster - Coordenador / Carles Sierra - Integrante., Financiador(es): Consolider-Ingenio - Outra.
