I'm a Professor in the Systems and Computing Department at the Federal University of Campina Grande (UFCG/Brazil). I obtained my Ph.D. from the School of Computing at the University of Leeds (United Kingdom). I hold M.Sc. and a B.Sc. degrees from the Systems and Computing Department at UFCG.
I've been serving as a reviewer for many different international journals (such as Knowldge-based Systems, International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, Trasactions in GIS, International Journal of Geographic Information Science) and for many different international conferences in Applied Computing and Artificial Intelligence. Among my current attributions as a researcher, I lead the research group at the Applied Intelligent Computing Lab (LACINA/UFCG) and I'm member of the Special Committee in Geoinformatics of the Brazilian Computing Society (SBC).
My research interests include topics in artificial intelligence, data modelling, knowledge representation, information retrieval, text mining and natural language processing. I'm particularly interested in spatial and spatio-temporal information: spatial and temporal language, Geographic Information Retrieval (GIR), modelling geospatial semantics; quality and interoperability of geographic information, spatial aspects of social networks, Volunteered Geographic Information (VGI), and trajectory analysis.
