Effective document retrieval using domain knowledge and semantics is one of the major challenges in Information Retrieval. Over the last years, there has been a growing interest in ontologies as an artifact for human knowledge representation and a critical component…

In the last decade several ways to formalize defeasible reasoning have been studied. A particular approach, defeasible argumentation, has been particularly successful to achieve this goal.
The inference process of argument-based systems is based on the interaction of ar- guments…

Argumentative formalisms have been widely recognized as knowledge representation and reasoning tools able to deal with incomplete and potentially contradictory informa- tion. All such formalisms are computationally demanding. Hence, optimizing argumen- tative systems has been approached from di erent views.

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 studies on the formation of psychology's professors were locating us in the construction process of the professional knowledge in professors but in psychologists that exercise the teaching too, visualizing the paper that built knowledge assumed between both environments (academic…

La finalidad de este proyecto es la de generar una metodología, con las técnicas y herramientas corerspondientes; para brindar información relativa al costo de desarrollo de un Sistema Experto. En base a la propuesta, los CIO´s (Chief Information Officer) podrán…

Desde el Laboratorio Pericial Informático del Poder Judicial del Neuquén se impulsan actividades de I+D orientadas a la gestión del conocimiento aplicada al peritaje informático.
Se pretende generar un cuerpo de conocimientos que sea útil para la formación de profesionales…

Nowadays, data intensive applications are in constant demand and there is need of computing environments with better intelligent capabilities than those present in today's Database Management Systems (DBMS). To build such systems we need formalisms that can perform complicate inferences,…

The integral development of a conventional broadcasting radio and its emission through internet is an investigative initiative and a pedagogic development. This idea, together with the creation of educative and local contents, wins great relevance in the TIC and the…

Defeasible Logic Programming (DeLP) is a knowledge representation formalism that combines results from Logic Programming and Defeasible Argumentation to provide reasoning based on contradictory and potentially incomplete information. DeLP allows information representation by using weak rules and provides an argumentation…
