Javier Parapar is an Associate Professor at the Computer Science Department of the University of A Coruña, Spain, where he is part of the Information Retrieval Lab. His research interests are information retrieval, text mining, document engineering, text summarization and recommender systems. Lately, he is particularly interested on the modelling of the item recommendation task as a relevance ranking problem, pseudo-relevance feedback for opinion mining and applying text mining techniques for fighting cyber-crime on Internet. If you are looking for his technology transfer activities, we invite you to visit the IRLab site associated to their activity in the CITIC, the Research Center on Information and Communication Technologies of the University of A Coruña.
