This paper concerns the relationship between agents or multi-agent systems and distributed communities of practice. It presents a review of a number of agent and multiagent applications with features that could contribute to supporting distributed communities of practice. The association is promising because of features like autonomy, pro-activity, flexibility or ability to integrate systems that characterize agents and multi-agent systems. Furthermore, such an association is a step towards building mixed communities of humans and artificial agents. To understand how agents and multi-agent systems could answer some of the needs of distributed communities of practice, we organize the analyzed applications into five different categories defined by considering the main activities of a community, namely: Individual Participation, Synchronous Interactions, Asynchronous Interactions, Publishing and Community Cultivation. Such a classification helps us identify the relevant features of the current technology and determine some that should be further developed, e.g. to support community coordination or gather information related to virtual communities. For each application we selected, we present its main approach and point out its potential interest.
ResumoCom a chegada iminente da TV Digital na escola brasileira, a pesquisa investigou a percepção dos docentes sobre a possibilidade de produzir objetos educacionais para essa mídia dentro da escola. 50 respondentes entre professores regentes, professores que já produzem material didático e futuros pedagogos, participaram da pesquisa por meio de entrevistas e questionários. Os resultados mostram que, em média, 80% dos entrevistados percebem a televisão digital como um grande repositório de conteúdos. Embora possuam habilidades para utilizar diferentes mídias, aparatos tecnológicos, ferramentas de comunicação e interação social, a possibilidade de produzir conteúdos didáticos audiovisuais ainda não é claramente percebida como importante pela maioria dos respondentes. Essa percepção tem impacto direto nas possibilidades de oferta de recursos e atividades que podem congregar alunos em atividades de aprendizagem. A partir dos dados, chegou-se a duas condicionantes que podem contribuir para a capacitação docente audiovisual. Palavras-chave: TV Digital. Docentes. Produção de conteúdos digitais.

AbstractWith the imminent arrival of Digital TV in the Brazilian schools, this research investigated the perceptions of teachers about the possibility of producing educational materials for that media inside the school. There were 50 participants among regent teachers, teachers who have already been producing educational materials and future pedagogues that participated in the survey through interviews and questionnaires. The results show an average of 80% who realize digital television is as a vast repository of contents. Although they have skills to use different media, technological devices, tools for communication and social interaction, the possibility of producing audio-visual educational content is not yet clearly considered as important by most of them. From the data, it was possible to reach two conditioning factors that can contribute for teachers´ audiovisual training.
This paper discusses a tool to study the relations among group members of a social network that evolve using a virtual environment. Understanding how these relations are built and maintained is essential to foster favorable conditions that can facilitate collective and individual learning. The focus of interest is how inner relations affect both the collective and individual learning of its members. We consider a group as being a set of relations among people and artifacts. As an example, we might determine which relations among members of a Project Team (predominantly goaloriented) are different from the ones found in Communities of Practice (predominantly learningoriented), and how they affect the learning of their members. We propose to characterize the relations among members by analyzing text content of social exchanges (e.g. email messages, blog posts, chat sessions, etc). The approach originality relies on taking into account the distinct points of view of its actors. Due to the distributed character of the problem (a virtual group), we intend to develop this tool by using a Multi-Agent System, whose architecture we present in this paper.
