It builds on previous work on the formalisation of FCG in terms of First Order Logic (FOL) concepts, more specifically on the definition of its core inference operations, unification and merge, in terms of FOL unification and search in the space of a particular set of FOL terms called structure arrangements. An implementation of such inference operations based on Logic Programming and Artificial Intelligence techniques such as unification and heuristic search is outlined.

The conceptualisation and language acquisition processes in each individual agent are based on general purpose cognitive capacities, such as categorisation, discrimination, evaluation and induction. The emergence of a shared language in the population results from a process of selforganisation of a particular type of linguistic interaction which takes place among the agents in the population. The experiments, which extend previous work by addressing the problem of the acquisition of both the semantics and the syntax of propositional logic, show that at the end of the simulation runs the agents build different conceptualisations and different grammars. However, these conceptualisations and grammars are compatible enough to guarantee the unambiguous communication of propositional logic sentences. Furthermore the categorisers of the perceptually grounded and logical categories built during the conceptualisation and language acquisition processes can be used for some forms of common sense reasoning, such as determining whether a sentence is a tautology, a contradiction, a common sense axiom or a merely satisfiable formula.

An approach based on general purpose cognitive capacities such as invention, adoption, parsing, generation and induction is proposed. Self-organisation principles are used to show how a shared set of preferred lexical entries and grammatical constructions, i.e., a language, can emerge in a population of autonomous agents which do not have any initial linguistic knowledge. Experiments in which a population of autonomous agents constructs a grammar that allows communicating the formulas of a propositional logic language are presented. These experiments extend previous work by considering a larger population and a much larger search space of grammar rules. In particular the agents are allowed to order the expressions associated with the constituents of a logical formula in arbitrary order. Previous work assumed that the expressions associated with the connectives should be placed in the first position of the sentence.

In this paper we propose a weighted list of skills for a undergraduate degree in Informatics Engineering, classified into two groups: technical and generic. Technical skills are divided into five different itineraries:computer engineering, computer science, information systems, information technologies and software engineering. Los planes de Estudios del EEES (Espacio Europeo de Educación Superior) deben ser diseñados a partir de competencias profesionales, de forma que al final de sus estudios el egresado se convierta en un profesional competente en el mercado laboral. En este artículo se propone una lista de competencias ponderada para un título de Grado en Ingeniería Informática clasificadas en dos grupos: transversales y técnicas. Dentro de las técnicas se definen cinco itinerarios distintos: computación, ingeniería de computadores, ingeniería del software, sistemas de información y tecnologías de la Información.
