  • A middleware for building contract-aware agent-based services 

    Confalonieri, Roberto; Álvarez Napagao, Sergio; Panagiotidi, Sofia; Vázquez Salceda, Javier; Willmott, Steven Nicolás (Springer Verlag, 2008)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a middleware to help designers in the implementation of contract-aware agent-based services. The middleware provides several components, including a contract manager, a communication manager and a ...
  • A preference meta-model for logic programs with possibilistic ordered disjunction 

    Confalonieri, Roberto; Nieves Sánchez, Juan Carlos; Vázquez Salceda, Javier (CEUR Workshop Proceedings, 2009)
    Text en actes de congrés
    Accés obert
    This paper presents an approach for specifying user preferences related to services by means of a preference meta-model, which is mapped to logic programs with possibilistic ordered disjunction following a Model-Driven ...
  • Answer set programming for computing decisions under uncertainty 

    Confalonieri, Roberto; Prade, Henri (Springer, 2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Possibility theory offers a qualitative framework for modeling decision under uncertainty. In this setting, pessimistic and optimistic decision criteria have been formally justified. The computation by means of possibilistic ...
  • Handling exceptions in logic programming without negation as failure 

    Confalonieri, Roberto; Prade, Henri; Nieves Sánchez, Juan Carlos (Springer, 2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Default rules, i.e. statements of the form normally a’s are b’s, are usually handled in Answer Set Programming by means of negation as failure which provides a way to capture exceptions to normal situations. In this paper ...
  • Logic programs with possibilistic ordered disjunction 

    Confalonieri, Roberto; Nieves, Juan Carlos; Vázquez Salceda, Javier (2009-05)
    Report de recerca
    Accés obert
    Logic programs with ordered disjunction have shown to be a flexible specification language able to model common user preferences in a natural way. However, in some realistic scenarios the preferences should be linked to ...
  • L’Scratch com a suport educatiu d’introducció a la programació en la classe de matemàtiques 

    Confalonieri, Roberto (Universitat Politècnica de Catalunya, 2013-06-26)
    Projecte Final de Màster Oficial
    Accés obert
    L'ús de les tecnologies de la informació i la comunicació (TICs) en l'escola secundària obligatòria (ESO) tracta de millorar els processos d'ensenyament i d'aprenentatge que, de forma quotidiana, es desenvolupen a l'aula. ...
  • Nested logic programs with ordered disjunction 

    Confalonieri, Roberto; Nieves Sánchez, Juan Carlos (CEUR Workshop Proceedings, 2010)
    Text en actes de congrés
    Accés obert
    In this paper we define a class of nested logic programs, nested logic programs with ordered disjunction (LPODs+), which allows to specify qualitative preferences by means of nested preference expressions. For doing this ...
  • The Role of preferences in logic programming: nonmonotonic reasoning, user preferences, decision under uncertainty 

    Confalonieri, Roberto (Universitat Politècnica de Catalunya, 2011-12-02)
    Tesi
    Accés obert
    Intelligent systems that assist users in fulfilling complex tasks need a concise and processable representation of incomplete and uncertain information. In order to be able to choose among different options, these systems ...
  • Towards the implementation of a preference-and uncertain-aware solver using answer set programming 

    Confalonieri, Roberto; Nieves Sánchez, Juan Carlos; Vázquez Salceda, Javier (2010)
    Report de recerca
    Accés obert
    Logic programs with possibilistic ordered disjunction (or LPPODs) are a recently defined logic-programming framework based on logic programs with ordered disjunction and possibilistic logic. The framework inherits the ...
  • USE: a multi-agent user-driven recommendation system for semantic knowledge extraction 

    Lopes, João Sousa; Álvarez Napagao, Sergio; Confalonieri, Roberto; Vázquez Salceda, Javier (2009-06-15)
    Report de recerca
    Accés obert
    Semiotics is a field where research on Computer Science methodologies has focused, mainly concerning Syntax and Semantics. These methodologies, however, are lacking of some flexibility for the continuously evolving web ...
