Reasoning about Temporal Context using Ontology and Abductive Constraint Logic Programming

The underlying assumptions for interpreting the meaning of data often change over time, which further complicates the problem of semantic heterogeneities among autonomous data sources. As an extension to the COntext INterchange (COIN) framework, this paper introduces the notion of temporal context as a formalization of the problem. We represent temporal context as a multi-valued method in F-Logic; however, only one value is valid at any point in time, the determination of which is constrained by temporal relations. This representation is then mapped to an abductive constraint logic programming framework with temporal relations being treated as constraints. A mediation engine that implements the framework automatically detects and reconciles semantic differences at different times. We articulate that this extended COIN framework is suitable for reasoning on the Semantic Web.

A juridical-practical framework for the investigation of crimes against granting of public housing services

The public service enterprises are victims of crimes and felonies which may reduce their capacity to perform their functions. These enterprises expend much money and effort in order to prevent those criminal behaviors. For this reason they ask from the authorities more efficient measures against crime; however, such enterprises may feel that they are not being given sufficient importance and/or remedies in dealing with such crime. The aim paper of this is not to study the problem from de substantive criminal law point of view. Rather, this paper’s goal is to study the Colombia’s Rules of Criminal Procedure, which regulate the investigation of this kind of crime. The article will look particularly at the competency of the relevant authorities at the investigative stages. Finally, it will make some recommendations regarding a proper route towards the investigation of these criminal behaviors.

Technical instruments and conceptual definitions: theoretical and practical implications of the change on the definition of unemployment in Colombia

En junio de 2000 el Departamento Nacional de Estadística de Colombia adopto una nueva definición de medición de desempleo siguiendo los estándares sugeridos por la organización Internacional del Trabajo (OIT). El cambio de definición implico una reducción de la tasa de desempleo en cerca de dos puntos porcentuales. En este documento contrastamos la experiencia colombiana con otra experiencias internacionales, y analizamos las implicaciones empíricas y teóricas de este cambio de definición usando dos tipos de estimaciones cuantitativas: en la primera se contrasta las principales características de las diferentes categorías clasificadas según la definición nueva y vieja de desempleo (empleado, desempleado y fuera de la fuerza laboral) usando el algoritmo EM; en la segunda se pone a prueba la implicación del desempleo estructural y su relación con el perfil educacional de personas desempleadas y las características teóricas que enfrentan los estándares de la OIT en la definición de empleo.

LMS software study and a practical application in language and literature didactics. 'Aplicación práctica en Didáctica de la lengua y la literatura del software LMS'.

Resumen en español

A practical introduction to first steps : assessment, teaching and learning. 'Una introducción práctica a los primeros pasos : evaluación, enseñanza y aprendizaje'.

Es un recurso pensado para apoyar a los docentes en la labor de mejorar los niveles de alfabetización infantil y, alcanzar los objetivos que se han marcado para los estudiantes y las escuelas. Para ello, se establece la evaluación de este proceso de enseñanza del lenguaje oral y escrito, a través del llamado 'proceso de desarrollo continuo', por el cual el profesor puede supervisar y evaluar el progreso de sus alumnos desde la guardería y en los sucesivos años de escolarización, mediante la utilización de estrategias que cubran las necesidades específicas de cada uno de ellos en el contexto de la misma clase.
