26About Me
Orlando Belo is Associate Professor, with Habilitation, in the Department of Informatics at University of Minho, Portugal. He is a member of the Department of Informatics at University of Minho since 1986, and a member of the ALGORITMI R&D Centre, at the same university, working in Business Intelligence, with particular emphasis in areas like Databases, Data Warehousing Systems, OLAP, Dashboarding, and Data Mining. During the last few years he was involved with several projects in the decision support systems area designing and implementing computational platforms for specific applications like fraud detection and control in telecommunication systems, data quality evaluation, and ETL systems for industrial data warehousing systems. He received a 5-year degree in Systems and Informatics Engineering in 1986, done “Provas de Aptidão Pedagógica e Capacidade Científica” (MSc equivalent) in 1991 in Expert Systems, finished its Ph.D. thesis in Multi-Agent System in 1998 in the Department of Informatics at University of Minho, and got his Habilitation in 2013. He published several scientific works, most of them in international conferences with peer reviewing, related to his main researching areas, with particular emphasis in Business Intelligence, Business Analytics, Data Warehousing Systems, On-Line Analytical Processing, and Data Mining applications. In recent years, his R&D activities have been developed mainly in the areas of Ontology Learning and Sentiment Analysis.
