  • Predict
    National project (TIN2011-28538-C02), January 2012 - December 2013
    The Predict project addresses the extension of information access technologies towards the incorporation of new dimensions, namely novelty and diversity, subjectivity, context, and time, as essential aspects of information access effectiveness and tasks that are not captured in traditional Information Retrieval (IR) paradigms and models, in order to enhance the quality, effectiveness, and user satisfaction with retrieval systems, in further ways than state of the art technologies and theories in the field currently procure. The research focuses on these problems within the specific scope of personalized Information Retrieval and Recommender Systems.
  • ReSHeT: Recommender Systems in the Social Web: Heterogeneity and Time Dimension
    Regional project (CCG10-UAM/TIC-5877), January 2011 - December 2011
    The ReSHeT project addresses two improvements in Recommender Systems for the Social Web: the consideration of information heterogeneity and the inclusion of the time dimension. Specifically, it proposes the development of recommendation models that make use of user preferences from several sources (ratings, annotations, and resource consumptions, social networks, etc.), and can be applied to resources belonging to different media (text, image, audio, video). By testing these models on a dataset obtained from a real social system, we shall analyse factors that are influenced by time (e.g. changes in user preferences, differences among the user's preferences according to the time of day or the month of the year, resources subject to fashions and trends, etc.). Based on such analysis, we shall propose and evaluate a strategy to change or adjust the developed recommendation models over time.
  • MA2VICMR: Mejorando el acceso, el análisis y la visibilidad de la información y los contenidos multilingües y multimedia en red para la Comunidad de Madrid
    National project (S2009TIC-1542), January 2010 - December 2013
    The MAVIR Consortium is a research network co-funded by the Community of Madrid under the 4th Regional Plan for Scientific Research and Technological Innovation (IV PRICIT). It is formed by a multidisciplinary team of scientists, technicians, linguists and archivists to develop an integration effort in research, training and technology transfer. The research lines that are developed by MAVIR members belong to Natural Language Technologies and Scientific Communication through the Web.
  • RIM3. Information Retrieval on different media based on multidimensional models: relevance, novelty, personalization and context
    National project (TIN-2008-06566-C04-02), January 2009 - December 2011
    This project tackles the IR problem from a multidimensional perspective. Besides the dimension of relevance, systems could be endowed with advanced capabilities for novelty detection, redundancy filtering, subtopic detection, personalization and context-based retrieval.

  • MESH: Multimedia sEmantic Syndication for enHanced news services
    EU/FP6 Integrated Project (FP6-027685), March 2006 - February 2009
    MESH applies multimedia analysis and reasoning tools, network agents and content management techniques to extract, compare and combine meaning from multiple multimedia sources, and produce advanced personalized multimedia summaries, deeply linked among them and to the original sources to provide end users with an easy-to-use "multimedia mesh" concept, with enhanced navigation aids. A step further is to empower users with the means to reuse available content by offering media enrichment and semantic mixing of both personal and network content, as well as automatic creation from semantic descriptions.

    The main technological objectives of aceMedia project are to discover and exploit knowledge inherent to the content in order to make content more relevant to the user; to automate annotation at all levels; and to add functionality to ease content creation, transmission, search, access, consumption and re-use. In addition, available user and terminal profiles, the extracted semantic content descriptions and advanced mining methods will be used to provide user and network adaptive transmission and terminal optimised rendering.

    The definition of XBRL taxonomies and OWL ontologies for investment funds. The principal aim is to evaluate the use of XBRL vs. the use of OWL in the financial domain, in order to cross-fertilize both research lines and to assess the applicability of both languages to the financial market.
  • AE3. Learning, Evolution and Extreme Statistics
    National project (TIN-2004-07676-C02-01), December 2004 - November 2007
    The overall aim of the "Learning, Evolution and Extreme Statistics" (AE3 in its Spanish initial letters) project is to study those hard pattern recognition problems where objects of interests are statistically overwhelmed by others, in three concrete areas: natural image statistics, extreme sample classification and time modeling in finance. The main techniques to be used are machine learning, computer vision or neurobiological modelling.
