The knowledge imperfections should be considered when modeling complex problems. A solution is to develop a model that reduces the complexity and another option is to represent the imperfections: uncertainty, vagueness and incompleteness in the knowledge base. This paper proposes…

The Knowledge Engineering Suite is an ontology production method, based on relationship networks, for knowledge representation inside specific contexts. The production of these ontologies has three basic steps, since catching the client data, knowledge base creation, and information retrieval and…

This paper proposes an original generic hierarchical framework in order to facilitate the modeling stage of complex autonomous robotics mission planning problems with action uncertainties. Such stochastic planning problems can be modeled as Markov Decision Processes [5]. This work is…

Given an instance of an optimization problem together with an optimal solution, we consider the scenario in which this instance is modified locally. In graph problems, e. g., a singular edge might be removed or added, or an edge weight…

A new species of Seticornuta from Brazil is described and illustrated, the frst record of this genus for the Brazilian fauna. This new species was found in a study that aimed to enhance knowledge of the Brazilian fauna of Metopiinae,…

Se presentan los resultados de un proyecto etnobotánico que pretende rescatar el conocimiento vegetal y la etnomedicina entre los indígenas Warao de la Isla de Araguabisi y de Tucupita en el estado Delta Amacuro. El trabajo de campo se realizó…

Reflete sobre o papel das bibliotecas públicas na educação de usuários para o conhecimento da ciberviolência. Tal fenômeno é expresso através das Tecnologias de Informação e Comunicação (TIC), as quais são utilizadas para causar danos às vítimas. O trabalho fundamenta-se…

It is interesting and important to compare, analyze and assess the alternative tools that could be used in the area of Knowledge Representation. In this paper we present a reasearch line associated to this goal: to formally establish the relation…

The Intellectual Creation Diffusion Service (SeDiCI) of the UNLP was created with the main objective of communicating to the society all the knowledge acquired in different academic fields of our university. This is how we can return all the efforts…
