Dissertação( PROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA DE ELETRICIDADE/CCET) - Universidade Federal do Maranhão, [São Luis] .http://tedebc.ufma.br:8080/jspui/handle/tede/1877This work introduces PROPOST (Project Portfolio Support Tool), a knowledgebased software tool for supporting Project Portfolio Management – an increasing management model nowadays. This tool focuses on a project definition process, and was modeled using the MAAEM methodology and the ONTORMAS ontology-driven tool, as well as by reusing the ONTOINFO and ONTOWUM ontologies, which describe software product families for the development of Information Retrieval and Filtering applications, respectively. PROPOST looks for providing resource optimization by supporting reuse of existing information systems as well as avoiding duplicity on project definition for the composition on the organization’s software portfolio. The tool was created not only as a contribution for solving a current problem related to redundancy on portfolio definition, as well as support for several activities related to portfolio management (select, prioritization and evaluation). The development of PROPOST provides references on how ontology-based development can help in the software development process. It also contributes as a case study for evaluating the MAAEM methodology and the ONTORMAS ontology used in modeling process, having provided several hints for their improvement.application/pdfAcesso AbertoGestão de Portifólio; Sistemas de Recomendação; Mineração de uso; Filtragem Colaborativa; Recuperação da Informação; Gerência de ProjetosPortfolio Management; Recommender Systems; Usage Mining; Collaborative Filtering; Information Recovery; Project ManagementSistemas de InformaçãoDissertação
