The area of Knowledge Representation and Reasoning has been enriched during the past two decades with the addition of Argument-Based Reasoning Systems. In formal systems of defeasible argumentation, arguments for and against a proposition are produced and evaluated to test…

Recent advances in biology have afforded scientists with the knowledge that polysaccharides play an active role in modulating cellular activities. Glycosaminoglycans (GAGs) are one such family of polysaccharides that play a very important role in regulating the functions of numerous…

The proper interpretation of measurements from an optical fiber sensor requires a full understanding of its mechanical response to external action and the corresponding change in optical output. To quantify the mechanical behavior it is necessary to know the mechanical…

The application of the multilingual knowledge encoded in Wikipedia to an open–domain Cross–Lingual Question Answering system
based on the Inter Lingual Index (ILI) module of EuroWordNet is proposed and evaluated. This strategy overcomes the problems due to
ILI’s low coverage…

The necessity of verification tools for Knowledge Based-Systems (KBSs), that help to guarantee a certain degree of quality and reliability of these systems will increase in the future when more critical systems are developed in areas such as industry, science,…

Depuis plusieurs années, on assiste à la création de programmes en prévention du suicide à l’adolescence. L’un de ces programmes repose sur le principe des pairs aidants. Il consiste à former des jeunes dont le rôle est d’apporter du soutien…

En los últimos años las relaciones de cooperación entre firmas han surgido como una nueva forma de organización de la producción que favorece los procesos de aprendizaje y transferencia de conocimiento interorganizacional. Estas formas de cooperación y en particular el…
