Technology in the 21st Century: New Challenges and Opportunities

Although big data, big data analytics (BDA) and business intelligence have attracted growing attention of both academics and practitioners, a lack of clarity persists about how BDA has been applied in business and management domains. In reflecting on Professor Ayre's contributions, we want to extend his ideas on technological change by incorporating the discourses around big data, BDA and business intelligence. With this in mind, we integrate the burgeoning but disjointed streams of research on big data, BDA and business intelligence to develop unified frameworks. Our review takes on both technical and managerial perspectives to explore the complex nature of big data, techniques in big data analytics and utilisation of big data in business and management community. The advanced analytics techniques appear pivotal in bridging big data and business intelligence. The study of advanced analytics techniques and their applications in big data analytics led to identification of promising avenues for future research

Diseño de una metodología para la extracción de funciones y mapas relacionales a partir de herramientas de minería de texto

En las organizaciones, uno de los problemas más frecuentes es la ausencia de un procedimiento para documentar, sistematizar y recopilar la información relativa a las nociones de cargos específicos. Esta situación se da en especial, cuando se trata de trabajadores del conocimiento. Estos son entendidos como aquellos cuya labor dentro de a organización está relacionada a sus habilidades para crear comunicar conocimiento. Frente a lo anterior, la Minería de Texto se convierte en una herramienta para extraer una fracción de tales actividades y relaciones, para encontrar dentro en el correo electrónico la respuesta a este conocimiento desaprovechado.In organizations, one of the most common problems is the absence of a procedure for document, systematize and gather information on the functions the perform.

Trabalho de Projecto apresentado como requisito parcial para obtenção do grau de Mestre em Estatística e Gestão de InformaçãoNa presente dissertação, desenvolveu-se um protótipo que recorre a um programa de categorização textual (o software Teragram TK 240) para estudar o Diário da Assembleia da República (DAR), 1.ª Série, IX Legislatura (2002-2005). Com base na descrição das emoções dos deputados presente nos DAR, analisaram-se as reacções dos Grupos Parlamentares durante os debates parlamentares, com o intuito de compreender de que modo é que estas reflectem a articulação dos diferentes Grupos Parlamentares entre si e em relação ao Governo. Para contextualizar o modelo desenvolvido, fez-se um breve enquadramento teórico sobre os principais temas implicados, nomeadamente a categorização textual e o text mining
