I have received my PhD degree from University of A Coruña in 2008. My thesis title was Index Compression for Information Systems . At 2009 I joined Yahoo! Research's Natural
Language
Retrieval group in
Barcelona. My main areas
of research are information
retrieval
(IR), applications of
natural language processing (NLP), Web search and large-scale information access in general.
ECIR 2007 Talk (on static pruning of terms) slides
Glasgow University seminar (on compression and inverted index
construction) slides
SIGIR 2005 Poster (on the NP-completeness of the document identifiers
assignment problem) slides
ECIR 2005 Talk (on document identifiers reassignment) slides
