In this paper a methodology for accesing scientific data repositories on data grids is proposed. This methodology is based on ontology specification and knowledge representation. The concept of Knowledge Perspective is introduced, as the action of applying particular scientific conjectures…

Information systems play an ever-increasing key role in our society. In particular, data intensive applications are in constant demand and there is need of computing environments with much more intelligent capabilities than those present in today’s Data-base Management Systems (DBMS).…

Mediante técnicas paleoparasitológicas cuantitativas y cualitativas se examinaron los sedimentos de la cavidad pélvica de dos esqueletos humanos. Los individuos fueron hallados en dos enterratorios asociados al asentamiento español de fines de siglo XVI "Nombre de Jesús" (Cabo Vírgenes, provincia…

Since huge amounts of spatial data can be easily collected from various applications, ranging from remote sensing technology to geographical information system, the extraction and comprehension of spatial knowledge is a more and more important task. Many excellent studies on…

Conocida como ácido ascórbico, la Vitamina C es una vitamina que interviene en múltiples procesos, tales como: formación de hormonas, neurotransmisores, carnitina, conversión del colesterol en ácidos biliares, incremento en la absorción de hierro, además de su fundamental intervención en…

Se requería incorporar nuevos elementos al conocimiento acerca de la caracterización y control de la calidad de la vacuna antimeningocócica cubana VA-MENGOC BC® para demostrar su seguridad y elevar su competitividad en el mercado. Se combinaron métodos como la cromatografía…

In the last few years, several studies have emphasized the use of ontologies as an alternative to organization of the information.
The notion of ontology has become popular in fields such as intelligent information integration, information retrieval on the Internet,…

Little has been written about the component provision problem (programming plans and domain concepts) for the repositories of knowledge in program understanding systems and reports that specifically address this issue are unknown. Model-driven and plan-driven approaches use repositories where construction…

This work describes the ontology construction process for the development of an Intelligent System for the Organization and Retrieval of Knowledge in Biodiversity – SISBIO. The system aims at the production of strategic information for the biofuel chain Two main…
