Doctoral Consortium 2013 at LSI-UNED

The second edition of this Doctoral Consortium provides a venue for student researchers investigating topics in Natural Language Processing and Multimedia Information Retrieval to present their work in progress and to receive feedback from a panel of senior researchers. This event aims to explore, discuss and broad ideas. The forum includes talks by two invited speakers and a specialized mini-workshop open to a general audience.
