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…

National Research and Education Network organizations (NRENs) provide advanced information and communication technology (ICT) services for the academic community of their country. Their focus is often on providing affordable high speed bandwidth amongst their members and to other research networks,…

Même si le mot est ancien, la référence à la notion de document est récente dans l'Histoire, sans doute en résonance avec l'organisation de la société industrielle, sa régulation et ses valeurs. Au tournant du millénaire, le web s'est appuyé…

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…

While entertainment web forums provide a dynamic medium for interaction, not many researchers feel the need to go deeply into the contents.
One of the reasons behind this attitude lies on a widely perceived assumption that web forums do not…

Tomando en cuenta el concepto de "aldea global" previsto por Marshall McLuhan hace más de 40 años, nos encontramos
ahora con la necesidad del desarrollo de una nueva epistemología que se aparte, definitivamente, de las nociones establecidas por la ciencia…

In the last few years, several studies have emphasized the use of ontologies as an alternative to organization of the information.
The notion of ontology has become popular in fields such as intelligent information integration, information retrieval on the Internet,…

This work describes the ontology construction process for the development of an Intelligent System for the Organization and Retrieval of Knowledge in Biodiversity – SISBIO. The system aims at the production of strategic information for the biofuel chain Two main…
