Research

Member of Centro de Informática e de Tecnologias de Informação - CITI.

My research interests concern the different aspects of Web and multimedia search and data mining: exploratory search and recommendation systems, machine learning methods for information extraction,  high-dimensional indexing and ranking algorithms, and graph based analysis of social-networks.  

Software

Most of my research is implemented as part of a set of tools that I use in my work.  In an extraordinary moment of inspiration I named it Multimedia Information Retrieval C++ SDK. Find out more.

Biography

João Magalhães holds a Ph.D. degree (2008) in Computer Science from Imperial College London, UK and both a M.Sc. (2002) and Engineering degree (1998) in Electrical and Computer Engineering from the Instituto Superior Técnico, Lisbon, Portugal.  He is currently an Invited Assistant Professor at the Department of Computer Science of the Faculty of Science and Technology of the Universidade Nova de Lisboa. Before that he was at the Instituto Superior de Engenharia de Lisboa (2002-2009) and at Siemens R&D (1997-2003) working in the area of multimedia and communications networks. His research interests cover the different problems of Web and multimedia information search and data mining: exploratory search and recommendation systems, machine learning methods for information extraction,  high-dimensional indexing and ranking algorithms, and graph based analysis of social-networks. Dr. Magalhães received the ACM International Conference in Image and Video Retrieval 2007 Best Paper Award, the Portuguese national engineering association Young Engineer Award in 2002, and the Siemens Innovation and Communications Award in 2002.
