Software Traceability for Multi-Agent Systems Implemented Using BDI Architecture

The development of multi-agent software systems is considered a complex task due to (a) the large number and heterogeneity of documents generated during the development of these systems, (b) the lack of support for the whole development life-cycle by existing agent-oriented methodologies requiring the use of different methodologies, and (c) the possible incompleteness of the documents and models generated during the development of the systems. In order to alleviate the above problems, in this thesis, a traceability framework is described to support the development of multi-agent systems. The framework supports automatic generation of traceability relations and identification of missing elements (i.e., completeness checking) in the models created during the development life-cycle of multi-agent systems using the Belief-Desire-Intention (BDI) architecture. Traceability has been recognized as an important activity in the software development process. Traceability relations can guarantee and improve software quality and can help with several tasks such as the evolution of software systems, reuse of parts of the system, validation that a system meets its requirements, understanding of the rationale for certain design decisions, identification of common aspects of the system, and analysis of implications of changes in the system. The traceability framework presented in this thesis concentrates on multi-agent software systems developed using i* framework, Prometheus methodology, and JACK language. Here, a traceability reference model is presented for software artefacts generated when using i* framework, Prometheus methodology, and JACK language. Different types of relations between the artefacts are identified. The framework is based on a rule-based approach to support automatic identification of traceability relations and missing elements between the generated artefacts. Software models represented in XML were used to support the heterogeneity of models and tools used during the software development life-cycle. In the framework, the rules are specified in an extension of XQuery to support (i) representation of the consequence part of the rules, i.e. the actions to be taken when the conditions are satisfied, and (ii) extra functions to cover some of the traceability relations being proposed and completeness checking of the models. A prototype tool has been developed to illustrate and evaluate the work. The work has been evaluated in terms of recall and precision measurements in three different case studies. One small case study of an Automatic Teller Machine application, one medium case study of an Air Traffic Control Environment application, and one large case study of an Electronic Bookstore application

A torção do mito fáustico ou a despedida da modernidade

O presente artigo busca pensar a forma como Dr. Fausto de Thomas Mann, Tragédia Subjectiva de Fernando Pessoa e Meu Fausto de Paul Valéry possibilitam um pensamento sobre a modernidade do século XX. Afinal, o que nos trouxe o projeto moderno? – pergunta-se cada qual. Onde está o indivíduo, ideia fundadora da modernidade? Percebe-se, assim, o momento no qual um dos mitos que nasce na modernidade incipiente e ganha força com o avançar da modernidade olha de frente os ideais que foram fundamentais para o seu surgimento. Momento de autorreflexão na qual a modernidade olha-se ao espelho, enxerga claramente as ilusões que a fomentaram e percebe que fora o seu movimento, os ideais que estão por traz da ideia de subjetividade, que impossibilitam agora, no início do século XX, aceitar prontamente as premissas modernas. O foco central, portanto, será o estudo das apropriações do início do século XX e da relação que a torção do mito fáustico possui com a ideia de despedida da modernidade. Torção é entendida aqui a partir da discussão trazida por Gianni Vattimo para a diferença entre as palavras Verwindung (torção) e Überwindung (superação) no contexto do pensamento pós-metafísico desenvolvido por Heidegger
