This paper discusses questions about communication of probabilistic knowledge in the light of current theories of agent communication. It will argue that there is a semantic gap between these theories and research areas related to probabilistic knowledge representation and communication,…

In systems where agents are required to interact with a partially known and dynamic world, sensors can be used to obtain further knowledge about the environment. However, sensors may be unreliable, that is, they may deliver wrong information (due, e.g.,…

The success of personal information agents depends on their capacity to both identify relevant information for users and proactively recommend context-relevant information. In this paper, we propose an approach to enable proactive context-aware recommendation based on the knowledge of both…

In this article we will introduce certain considerations that must be taken into account while implementing the change operations of the belief change theory. The abstract models of bellief change make no considerations in respecto to the internal structures of…

Cultural differences play a very important role in matching computer interfaces to the expectations of users from different national and cultural backgrounds. But to date, there has been little systematic research as to the extent of such differences, and how…

Implicitly exploitable parallelism for Logic Programming has received ample attention. Defeasible Argutmentation is specially apt for this optimizing technique. Defeasible Logic Programming (DLP), which is based on a defeasible argumentation formalism, could take full advantage of this type of parallel…

La realidad económica internacional presenta oportunidades que deben ser utilizadas para mejorar la calidad de vida de los argentinos y para superar los cuellos de botella que afectan al crecimiento y al desarrollo de las pequeñas y medianas empresas radicadas…

Odisea: Discurso y Narrativa, by Graciela Zecchin de Fasano, is the most sophisticated and convincing interpretation known to me concerning the varied and complex roles played by direct speech in Homer’s epic. In this wide-ranging and lucidly written work, Dra.…

This study investigates an approach of knowledge discovery and data mining in insufficient databases. An application of Computational Taxonomy analysis demonstrates that the approach is effective in such a data mining process. The approach is characterized by the use of…

El artículo recuerda los intentos de sistematización de saberes anteriores al Romanticismo y recapitula la evolución de la historiografía literaria durante los siglos XIX y XX para presentar después algunas reflexiones metodológicas con respecto a la clasificación de obras literarias…
