Estrategias para el diseño de ayudas didácticas y pedagógicas que potencien el desarrollo de los procesos de lecto-escritura en niños y niñas de quinto de primaria

Es posible determinar en este ensayo los distintos componentes pedagógicos que optimicen el desarrollo de la intelectualidad del ser humano, como sujeto activo del aprendizaje que tiene verdaderamente un significado, donde el docente debe generar o proponer al estudiante las herramientas didácticas hábiles y útiles para incrementar desde su saber teórico-práctico la adquisición del conocimiento, explorando el entorno que lo rodea y desde allí presentar una propuesta que se funde o interprete en el progreso de las humanidades. Es por ello que la pedagogía tiene la finalidad de precisar los procesos adecuados de aprendizaje, potencializando ca vez más las habilidades en el educando en la lecto-escritura

Using Patterns for Keyword Search in RDF Graphs *

ABSTRACT An increasing number of RDF datasets are available on the Web. Querying RDF data requires the knowledge of a query language such as SPARQL; it also requires some information describing the content of these datasets. The goal of our work is to facilitate the querying of RDF datasets, and we present an approach for enabling users to search in RDF data using keywords. We introduce the notion of pattern to integrate external knowledge in the search process, which increases the quality of the results

Supporting Mapping Adaptation when Sources Evolve

Abstract. In data integration systems such as data warehouses and mediators, heterogeneous data sources are integrated into a global representation. Consider such global representation defined by a schema, called target schema. Mappings are defined between the target schema and the source schemas to express the way instances of the target schema are derived from the data sources. Mappings necessarily depend on the schemas they relate while the sources freely evolve their description and make the mapping invalid. This paper presents an approach to automatically adapt a mapping after source schema evolutions. A set of changes are considered and the mapping is adapted for every considered change in three steps: (i) the original mapping is first checked to see if it is affected by the change; (ii) if the original mapping is affected, it is checked to see if it is adaptable; (iii) only if the mapping is adaptable, adapted mappings are generated.

An automatic tool for discovering complex mappings

The inter-operability of several autonomous and heterogeneous data sources is an important issue in many applications such as mediation systems, data-warehouses, or web-based systems. These systems provide a view, called a target schema, on th
