Scientific advances, especially in the healthcare domain, can be accelerated by making data available for analysis. However, in traditional data analysis systems, data need to be moved to a central processing unit that performs analyses, which may be undesirable, e.g. due to privacy regulations in case these data contain personal information. This paper discusses the Personal Health Train (PHT) approach in which data processing is brought to the (personal health) data rather than the other way around, allowing (private) data accessed to be controlled, and to observe ethical and legal concerns. This paper introduces the PHT architecture and discusses the data staging solution that allows processing to be delegated to components spawned in a private cloud environment in case the (health) organisation hosting the data has limited resources to execute the required processing. This paper shows the feasibility and suitability of the solution with a relatively simple, yet representative, c...

Abstract. The advent of Artificial Intelligence (AI) technologies has made it possible to build systems that diagnose a patient, decide on a loan application, drive a car, or kill an adversary in combat. Such systems signal a new era where software-intensive systems perform tasks that were performed in the past only by humans because they require judgement that only humans possess. However, such systems need to be trusted by their users, in the same way that a lawyer, medical doctor, driver or soldier is trusted in performing the tasks she is trained for. This creates the need for a new class of requirements, Trustworthiness Requirements, that we have to study in order to develop techniques for their elicitation, analysis and operationalization. In this paper, we propose a foundation to develop such techniques. Our work is based on an Ontology of Trust that answers questions about the nature of trust and the factors that influence it. Based on the answers, we characterize the class of trustworthiness requirements. Among other things, this characterization supports the requirements engineer in defining thurstworthi-ness requirements, identifying the risks presented by the system-to-be, and understanding the signals the system must emit to gain and maintain trust.

Abstract. Current developments in software agents, with respect to intelligence, flexibility, security and pro-activity, allow agent-based applications to be increasingly attractive to industry and commerce. Much of this research is concentrated on improving the level of application intelligence and therefore its efficiency within industrial settings. We argue that data mining techniques can improve substantially the agents' intelligence during a training process. This paper introduces Agent Academy, a framework that generates software ...

The focus of this research is the application of Information Retrieval (IR) techniques to support mutual interaction, ie free negotiation between the members of cooperative learning environments (CLE). The IR techniques are applied in order to support communication, more specifically, message's manipulation and organization and finding specific information.

Although agent technology has experienced much progress in the last few years, software engineers still struggle to make the shift to this new paradigm [1, 2, 3]. Two of the problems that can be cited in this context are: i) multiagent systems are composed of two or several agents, each of them having its own thread of control. The behavior of the system is given by the interactions of these separate programs, which brings challenges in modeling and developing them [2]; ii) agents are applied in scenarios which may require a high ...

Abstract. Collaborative learning motivates active participation of individuals in their learning process, which often results in the attaining of creative and critical thinking skills. In this way, students and teachers are viewed as both providers and consumers of knowledge gathered in environments where everybody teaches and learns, by interacting with each other. Peer-to-peer networking reflects and supports this non-hierarchical relationship between teachers and students in a collaborative learning community. In this paper we present Help&Learn, ...

Collaborative learning motivates active participation of individuals in their learning process, which often results in the attaining of creative and critical thinking skills. This way, students and teachers are viewed as both providers and consumers of knowledge gathered in environments where everybody teaches and learns, by interacting with each other.

Pesquisadores têm cada vez mais direcionado sua atenção ao uso de modelos em tempo de execução (runtime), provendo ferramentas e frameworks que auxiliam os desenvolvedores na tarefa de construir software alinhado a seus requisitos/arquitetura. Em particular, algumas pesquisas em Engenharia de Requisitos concentraram-se em desenvolver sistemas de software que possuam a capacidade de ler seus próprios modelos de requisitos e tomar decisões a partir de uma análise do mesmo. É uma tendência comum, por exemplo, na área de sistemas adaptativos, para a qual contribuímos recentemente. Neste artigo, propomos um novo projeto de pesquisa sobre o uso de modelos de requisitos em tempo de execução, discutindo seus potenciais benefícios e os desafios envolvidos.

This paper describes Biblioref, a collaborative system to support document sharing. In this system, document classification and sharing is based on the development of user's individual taxonomies, which are mapped into a reference taxonomy. The main benefits of this system can be described as: a) promoting collaboration among users through mutual access to each other's documents; b) granting user autonomy

The i* framework is a renowned Requirements Engineering ap- proach. This work is part of an ongoing effort to provide ontological interpreta- tions for the i* core concepts. With this, we aim at proposing a more uniform use of the language, in a way that it can be more easily learned by newcomers and more efficiently transferred to industry. Our approach is based on the appli- cation of a foundational ontology named UFO, which is used as a semantically coherent reference model to which the language should be isomorphic. In this paper, we focus on the Means-end and the Contribution links. We aim at pre- senting the community with some possible ontological interpretations of these links, aiming at promoting constructive debate and receiving feedback about the validity of our assumptions.

In recent years, there has been a growing interest in the application of foundational ontologies, i.e., formal ontological theories in the philosophical sense, to provide a theoretically sound foundation for improving the theory and practice of conceptual modeling. In this paper, we present advances on our re- search on the ontological foundations of conceptual modeling by addressing the concept of events. We present a foundational ontology of events (termed UFO- B) together with its axiomatization in first-order logic. Moreover, we report on an implementation of UFO-B using the computational logic language Alloy, and discuss its consistency, validation and possible uses.

This toolbox will attempt to mediate and facilitate the sharing of knowledge between peers, and promote community awareness, learning, and evolvement.
