      Martí Avilés, José Vicente; Sales Gil, Jorge; Marin, Raul; Jiménez Ruiz, Ernesto Hindawi Publishing Corporation (2012)
      Indoor localization in smoke conditions is one of the EU GUARDIANS project goals. When smoke density grows, optical sensors such as laser range finders and cameras cease to be efficient. Zigbee sensor networks provide an ...
    • openAccess   Logic-based assessment of the compatibility of UMLS ontology sources 

      Jiménez Ruiz, Ernesto; Cuenca Grau, Bernardo; Horrocks, Ian; Berlanga Llavori, Rafael BioMed Central (2011-03-07)
      Background: The UMLS Metathesaurus (UMLS-Meta) is currently the most comprehensive effort for integrating independently-developed medical thesauri and ontologies. UMLS-Meta is being used in many applications, including ...
    • openAccess   Ontology integration using mappings: towards getting the right logical consequences 

      Jiménez Ruiz, Ernesto; Cuenca Grau, Bernardo; Horrocks, Ian; Berlanga Llavori, Rafael Springer Verlag (Germany) (2009)
