Se presenta la Paradoja de Dios, un ejemplar de la Paradoja de Russell. De ella se deduce que la creencia 'Dios no se ha creado a sí mismo' es falsa, así como 'Dios se ha creado a sí mismo'. Además se enmarca la Paradoja de Dios en el contexto creacionismo-evolucionismo.

Inicio mi discurso con una perspectiva de las academias en España, incluida ésta, naturalmente, con referencia a mi ingreso en ella. Sigo con un apartado de Física para justificar mi inclusión en la sección de Físico-Químicas y continúo con otros tres apartados, Informática, Lenguaje y Educación, en los que se ha desenvuelto fundamentalmente mi act...

Relational Databases (RDBs) have been a popular device to store information for linguistic purposes since the days of machinereadable dictionaries. However, although the use of such technology provides a sound methodological framework, most developing efforts have put aside the database design and development issues due to different reasons. This i...

La enseñanza con computadoras empezó al comienzo de los años 60 en los EEUU. En Europa empezó poco más tarde. España no estuvo ausente de esa línea de I+D. En 1964 se inauguró un sistema de Enseñanza Asistida por Computadora pionero en Europa. Se construyeron los dispositivos periféricos de salida, así como el acoplamiento de los mismos a una compu...

We propose to apply relational databases (RDB) development methodologies to the design of lexical databases (LDB), which embody conceptual and linguistic knowledge. We represent the conceptual knowledge as an ontology, and the linguistic knowledge, which depends on each language, in lexicons. Our approach is based on a single language-independent o...

Semantic relations are an important element in the construction of ontologies and models of problem domains. Nevertheless, they remain fuzzy or under- specified. This is a pervasive problem in Software Engineering and Artificial Intelligence. Thus, we find semantic links that can have multiple interpretations in wide-coverage ontologies, semantic d...

Abstract Semantic relations are an important element in the construction of ontology-based linguistic resources and models of problem domains. Nevertheless, they remain under-specified. This is a pervasive problem in both Software E ngineering and Artificial Intelligence. Thus, w e find semantic links that can h ave multiple interpretations, abstra...

Existing lexical resources have taxonomic structure related problems that negatively impact the results of domain-specific applications. This is the result of an approach that focuses on implementation and content issues rather than on questions of design, semantic cleanness and application usefulness. Although taxonomy structuring methodologies ha...

Relational databases have been used to represent lexical knowledge since the days of machine-readable dictionaries. However, although software engineering provides a methodological framework for the construction of databases, most developing efforts focus on content, implementation and time-saving issues, and forget about the software engineering a...

Regardless of the knowledge representation schema chosen to implement a linguistic resource, conceptual design is an important step in its development However, it is normally put aside by developing efforts as they focus on content, implementation and time-saving issues rather than on the software engineering aspects of the construction of linguist...

In our previous work, we used a methodology based on software engineering principles to develop tools for building and querying electronic dictionaries based on a DAG-shaped taxonomy, with language learning purposes. However, the tools do not enforce any kind of control over the use of semantic relations during the DAG-shaped taxonomy construction....

Al irse multiplicando las bases de datos léxicas en diferentes formatos, ha crecido también la preocupación acerca del nivel de reusabilidad de los recursos léxicos. El intercambio e integración de datos, así como el desarrollo de software común, son importantes para evitar duplicaciones de esfuerzos y posibilitar el desarrollo de bases de datos de...

In general the global pedagogical goal of the creation and use of dictionaries is the mastery of languages. The specific goal is to facilitate the assimilation of basic linguistic concepts: lexicon, sense (meaning), semantic categories, lexico-semantic relations, etc. In this paper, we describe the linguistic concepts that constitute the pedagogica...

We are on the way of defining a methodology aimed to create software tools supporting linguistic knowledge bases. One of our main concerns is to formally represent knowledge using a sound software engineering approach. In this setting, we first consider the linguistic concepts found in a multilingual dictionary, as vocabulary, meanings, semantic ca...

Resumen El objetivo pedagógico general de la creación y uso de diccionarios monolingües es el dominio de la lengua materna. Más concretamente se pretende facilitar la asimilación de conceptos lingüísticos fundamentales: léxico, acepciones, categorías semánticas, ciertas relaciones léxico-semánticas y taxonomía. Se subrayan estos conceptos lingüísti...

This is a presentation of the historical development of human-computer interfaces in educational computer science, which makes it necessary for Natural Language Processing to understand and interpret the learner”s interventions. It is also an analysis of Lexical Databases and their application in education.

This paper is devoted to a way of intending to improve the language mastery of students in every subject and in a broad range of education levels by using computer-based tools involving linguistic resources. Lexicon concepts useful for language learning are involved in dictionaries and other kinds of linguistic resources. These concepts (vocabulary...

We present in this paper computer-based tools for language learning based on constructionism. We focus language learning on using and authoring multilingual dictionaries, which enable the assimilation of fundamental linguistic concepts (lexicon, meanings, semantic categories, semantic relationships, and taxonomy.) We have developed automatic tools...

1. La inquietud por el español. Existe una inquietud permanente por nuestra lengua. Últimamente se ha agudizado una desazón debida al uso incorrecto de la misma, sobre todo cuando su difusión es masiva, como ocurre en los medios de comunicación: TV y prensa fundamentalmente. Dice Domingo Ynduráin que los medios reflejan simplemente la realidad de l...

To synthesize combinational logic, programmable logic arrays (PLAs) may be used. Most programs for logical PLA optimization need to derive the complement of a Boolean function. In this paper we analyse the complexity of one of these algorithms and, later, we compare the upper bound of the algorithm with experimental results.

Banks add extra information to messages they exchange in order to ensure the dispatch authenticity. In this paper, we describe a system to automate the production and verification of these “authenticators”. This system can be applied with most algorithms used to authenticate telegraphic messages between banking entities. Functions used in the compu...

In modern information processing technology there is a significant tendency to connect microfilm and Computer Science Techniques to each other. The purpose of it is to automatize information retrieval systems. Such an automatized system is shown here. It consists of a central computer based on a microprocessor with an external storage disk, a micro...

En este trabajo se aborda el problema de la síntesis de funciones de conmutación multisalida, a partir de bloques cualesquiera también de salidas múltiples, e independientemente de las especificaciones (universalidad, completitud, etc.) de dichas funciones. La síntesis de una función multisalida se reduce a la descomposición iterativa de la función...

This Paper deals with the allocation of records on a linear storage device to minimize the average access time when the request probabilities to the recores are not independent. For sequential access, algorithms to obtain optimal and approximate solutions are presented. The approximation algorithm is also used with little modification for direct ac...

The first systems has carried out intrinsic programmed instruction by means of computers used only a little part of the computer facilities. Therefore, a later working line was to build special purpose systems consisting of a special electronic unit for controlling a display device or an item selector. Presently another valid way to do this is to s...

We propose to apply classical development methodologies to the de-sign and implementation of Lexical Databases(LDB), which embody concep-tual and linguistic knowledge. We represent the conceptual knowledge as an ontology, and the linguistic knowledge, which depends on each language, in lexicons. Our approach is based on a single language-independen...

In this paper, we present the methodology followed to develop tools for authoring and using a bilingual electronic dictionary. The general goal of our research line is to reach methodologies for the development of tools for creating Information Systems based on ontologies. Starting on this way, a conceptual model is defined, relying on the entity-r...

El conocimiento se divide en parcelas para estudiarlo. Lo mismo ocurre con la prolífica obra de Torres Quevedo. Pero hay una unidad de intención que no debe pasar desapercibida cuando se analizan sus trabajos. Lo que hoy se llaman Ciencias de la Ingeniería, como fundamentos de las aplicaciones útiles a la sociedad, y sus consecuencias prácticas, fu...
