Managing and analyzing Big Data is one of the most interesting challenges that new technologies have to face nowadays. Big Data does not only refer to different kinds of sources. It also means managing structured and unstructured data, real-time data streams, as well as semantic ontologies applied to data. Specifically, approaching Big Data requires the definition of new ways of operating, according the \"Building of information\" and the \"Visualization\" points of view. Information building involves tasks allowing data extraction from different repositories or sources, as well as data aggregation capabilities for different analytical purposes.
