- An approach for automated service selection and ranking using services choreographyPublication . Silva, Firmino; Chituc, Claudia-Melania; Grefen, PaulIn today’s highly competitive market, it is critical to provide customers services with a high level of configuration to answer their business needs. Knowing in advance the performance associated with a specific choreography of services (e.g., by taking into account the expected results of each component service) represents an important asset that allows businesses to provide a global service tailored to customers’ specific requests. This research work aims at advancing the state-of-the-art in this area by proposing an approach for service selection and ranking using services choreography, predicting the behavior of the services considering customers’ requirements and preferences, business process constraints and characteristics of the execution environment.
- An architecture for an effective usage of data mining in business intelligence systemsPublication . Azevedo, Ana; Santos, Manuel FilipeBusiness Intelligence (BI) is one emergent area of the Decision Support Systems (DSS) discipline. Over the last years, the evolution in this area has been considerable. Similarly, in the last years, there has been a huge growth and consolidation of the Data Mining (DM) field. DM is being used with success in BI systems, but a truly DM integration with BI is lacking. Therefore, a lack of an effective usage of DM in BI can be found in some BI systems. An architecture that pretends to conduct to an effective usage of DM in BI is presented.

- Arquitecturas dos sistemas de informação: uma comparação de abordagensPublication . Rodrigues, Luís Silva; Amaral, LuisMais de duas décadas após a sua introdução nos Sistemas de Informação (SI) continua a ser relevante falar e aplicar as arquitecturas dos SI nas organizações. A este facto não é alheio o reconhecimento da importância e criticidade das arquitecturas dos SI para o sucesso dos Sistemas e Tecnologias de Informação (SI/TI) nas organizações. Neste contexto, este artigo para além de reflectir sobre os tipos de arquitecturas nos SI, sua aplicabilidade e utilidade para as organizações, pretende fazer uma comparação entre as principais abordagens para a construção das arquitecturas dos SI.
- Caderneta Electrónica: Visão de Professores e Encarregados de Educação de Alunos do Ensino Básico da GalizaPublication . Abreu, António; P. Afonso, Ana; Rocha, Álvaro; Pérez Cota, ManuelA investigação aqui descrita explora a primeira fase de um projecto de investigação, cujo objetivo é introduzir uma nova forma de colaboração e comunicação entre a Escola Família, através de uma Caderneta Eletrónica (CE), em Espanha, nas escolas da Galiza. A CE surge para dar resposta às crescentes necessidades de colaboração entre a Escola e a Família, promovendo o processo ensino-aprendizagem e o sucesso educativo, tendo como suporte as Tecnologias da Informação e da Comunicação (TIC). Através de um questionário procurámos obter a perceção dos Professores e Encarregados de Educação (EE) relativamente à adoção de uma CE. Ambos os grupos salientaram a importância da comunicação entre a Escola e a Família e manifestaram interesse na CE, enquanto instrumento de comunicação bidirecional.
- Challenges of digital transformation in higher education institutions: a brief discussionPublication . Rodrigues, Luis SilvaLike many industries, Higher Education Institutions (HEIs) have been exploiting emerging technologies as a way to improve performance and adapt to the increasingly technology-driven society. Although digital transformation is most often associated with business organizations, it is also an important issue for HEIs and presents some challenges that must be considered when defining digital policies and strategies. In this paper, as a starting point for our research, a brief discussion on the main challenges of digital transformation in HEIs is presented.
- A DCAP for the social and solidarity economyPublication . Malta, Mariana Curado; Baptista, Ana Alice; Parente, CristinaThis article presents a work-in-progress version of a Dublin Core Application Profile (DCAP) developed to serve the Social and Solidarity Economy (SSE). Studies revealed that this community is interested in implementing both internal interoperability between their Web platforms to build a global SSE e-marketplace, and external interoperability among their Web platforms and external ones. The Dublin Core Application Profile for Social and Solidarity Economy (DCAP-SSE) serves this purpose. SSE organisations are submerged in the market economy but they have specificities not taken into account in this economy. The DCAP-SSE integrates terms from well-known metadata schemas, Resource Description Framework (RDF) vocabularies or ontologies, in order to enhance interoperability and take advantage of the benefits of the Linked Open Data ecosystem. It also integrates terms from the new essglobal RDF vocabulary which was created with the goal to respond to the SSE-specific needs. The DCAP-SSE also integrates five new Vocabulary Encoding Schemes to be used with DCAP-SSE properties. The DCAP development was based on a method for the development of application profiles (Me4MAP). We believe that this article has an educational value since it presents the idea that it is important to base DCAP developments on a method. This article shows the main results of applying such a method.
- Developing a metadata application profile for the daily hire labourPublication . Sen, Sangeeta; Raza, Nishat; Dutta, Animesh; Malta, Mariana Curado; Baptista, Ana AliceEMPOWER SSE is a Fundação para a Ciência e Tecnologia (FCT, Portugal) and Department of Science & Technology (DST, India), financed research project that aims to use the Linked Open Data Framework to empower the Social and Solidarity Economy (SSE) Agents. It is a collaborative project between India and Portugal that is focused on defining a Semantic Web framework to consolidate players of the informal sector, enabling a paradigm shift. The Indian economy can be categorized into two sectors: formal and informal. The informal sector economy differs from the formal as it is an unorganized sector and comprised of economic activities that are not covered by formal arrangements such as taxation, labor protections, minimum wage regulations, unemployment benefits, or documentation. The major economy in India depends on the skilled labor of this informal sector such e.g. daily labor, farmers, electricians, food production, and small-scale industries (Kalyani, 2016). The informal sector is mainly made of skilled people that follow their family job traditions, sometimes they are not even formally trained. This sector struggles with the lack of information, data sharing needs and interoperability issues across systems and organizational boundaries. In fact, this sector does not have any visibility to the society not having the possibility to do business as most of the agents of this sector do not reach the end of the chain. This blocks them from getting proper exposure and a better livelihood.
- E-partilha: desenvolvimento e utilização de um repositório de objectos de aprendizagemPublication . Gonçalves, Maria José Angélico; Pereira, Rui Humberto; Pérez Cota, ManuelNos novos ambientes de aprendizagem, construídos a partir das tecnologias digitais, a necessidade de promover a qualidade dos recursos educativos, normalmente designados por Learning Objects, que podem suportar a aprendizagem à distância, formal e informal, emerge como um dos grandes desafios que as instituições de ensino têm de enfrentar. Sendo dispendiosos, a reutilização e a partilha tornam-se, assim, uma necessidade premente. Este artigo apresenta um Learning Object Repository que tem como objectivo armazenar, disseminar e manter acessíveis Learning Objects.
- eHealth infrastructures and security in portuguese hospitals: benchmarking with european hospitalsPublication . Vidal de Carvalho, Joao; Rocha, Álvaro; Abreu, AntónioThe aim of this study is to describe and compare eHealth Infrastructures and Security in selected European Union (EU) countries. Using data available from the European Hospital Survey (2012/2013), the study reported in this paper analyses the adoption of five eHealth Infrastructures and Security indicators in Portuguese Hospitals, namely: Externally connected; Broadband; Single and unified wireless; Clear and structured rules on access to clinical data; and EAS (Enterprise Archiving Strategy) for disaster recovery in less than 24 hours. The analysis of these eHealth indicators allows us to understand the position of Portugal in relation to the European average. It has been found that the Portuguese Hospitals are well positioned with regard to the adoption of these indicators and in spite of this, remains a permanent concern to raise the eHealth Infrastructures and Security levels through new projects in progress.
