  • Debenham, John; Sierra, Carles (IEEE, 2008)
    Successful negotiators look beyond a purely utilitarian view. We propose a new agent architecture that was inspired by the observation that "Everything that an agent says gives away (valuable) information.'' It is intended ...
  • Debenham, John; Sierra, Carles (IEEE Computer Society, 2009)
    An agent architecture supports the two forms of deliberation used by human agents. The work is founded on the two forms of rationality described by the two Nobel Laureates Friedrich Hayek and Vernon Smith. Cartesian, ...
  • Bogdanovych, Anton; Berger, Helmut; Simoff, Simeon; Sierra, Carles (IADIS, 2004)
  • Drago, Sara; Bogdanovych, Anton; Ancona, Massimo; Simoff, Simeon; Berger, Helmut; Sierra, Carles (ACS Inc, 2006)
  • Bogdanovych, Anton; Simoff, Simeon; Sierra, Carles; Berger, Helmut (IADIS Press, 2005)
    The growing demand for shopping assistants in E-Commerce was identified by many researchers. Some retailers try to address this need by introducing totally autonomous agents; others make extensive use of human resources, ...
  • Debenham, John; Sierra, Carles (AAAI Press, 2007)
    Successful negotiators look beyond a purely utilitarian view. We propose a new agent architecture that integrates the utilitarian, information, and semantic views allowing the definition of strategies that take these ...
  • Sierra, Carles; Debenham, John (INESC, 2008)
    Information-based agency is founded on two observations: everything in an agent's world model is uncertain, and everything that an agent communicates gives away valuable information. The agent's deliberative mechanism ...
  • Sierra, Carles; Debenham, John (ACM, 2005)
    In this paper we present a rich decision model for intelligent agents involved in multi issue negotiations. The model, grounded on information theory, takes into account the aspects of trust and preference to devise ...
  • Sierra, Carles; Debenham, John (CNR - National Research Council, 2009)
    Information-based agents use tools from information theory to evaluate their utterances and to build their world model. When embedded in a social network these agents measure the strength of information flow in this sense. ...
  • Sierra, Carles; Debenham, John (AMC Press, 2007)
    Successful negotiators prepare by determining their position along five dimensions: Legitimacy, Options, Goals, Independence, and Commitment, (LOGIC). We introduce a negotiation model based on these dimensions and on two ...
  • Debenham, John; Sierra, Carles (Springer Verlag, 2008)
    A pair of 'trust maps' give a fine-grained view of an agent's accumulated, time-discounted belief that the enactment of commitments by another agent will be in-line with what was promised, and that the observed agent will ...
  • Fabregues, Angela; Madrenas, Jordi; Sierra, Carles; Debenham, John (IEEE Computer Society, 2009)
    Autonomous entities in a digital ecosystem are expected to interact, negotiate and make agreements. The work introduced in this paper focuses on how these autonomous entities evaluate and rank the other participants in the ...
  • Debenham, John; Sierra, Carles (IEEE, 2008)
    An argumentation based negotiation model is supported by information theory. Argumentative dialogues change the models of agents with respect to ongoing relationships. Trust and honour are key components. Trust measures ...
