      Article
      Accés obert
      Association rules have been used for obtaining information hidden in a database. Recent researches have pointed out that simple associations are insu cient for representing the diverse kinds of knowledge collected in ...
    • A logic of graph conditions extended with paths 

      Navarro Gomez, Marisa; Orejas Valdés, Fernando; Pino Blanco, Elvira; Lambers, Leen (2016)
      Text en actes de congrés
      Accés obert
      In this paper we tackle the problem of extending the logic of nested graph conditions with paths. This means, for instance, that we may state properties about the existence of paths between some given nodes. As a main ...

    • A logic programming approach to parsing and production in fluid construction grammar 

      Sierra Santibáñez, Josefina (Springer, 2012)
      Capítol de llibre
      Accés restringit per política de l'editorial
      This paper presents a Logic Programming approach to parsing and production in Fluid Construction Grammar (FCG). It builds on previous work on the formalisation of FCG in terms of First Order Logic (FOL) concepts, more ...
    • A logic-based environmental decision support system for the management of horizontal subsurface constructed wetlands 

      Garcia Gasulla, Dario; Poch Espallargas, Manel; Nieves Sánchez, Juan Carlos; Cortés García, Claudio Ulises; Turon, Clàudia (2012-04-02)
      Article
      Accés restringit per política de l'editorial
      The use of Horizontal Subsurface Constructed Wetlands (HSCWs) for treating wastewaters in small communities has increased in the last years due to HSCW’s ecological singularities. Unfortunately, the same singularities ...
    • A logic-based incremental approach to graph repair featuring delta preservation 

      Schneider, Sven; Lambers, Leen; Orejas Valdés, Fernando (Springer Nature, 2021-07-07)
      Article
