Europeana: Moving to Linked Open Data

Publicado por Pablo Hermoso de Mendoza González

26/02/2013

En este artículo los autores exponen como los datos de más de 23 millones de objetos culturales europeos están siendo estructurados, generándose los RDF necesarios para poder interoperar en el gran marco de la LINKED OPEN DATA web. Este proyecto promovido por la Unión Europea tiene como objetivo recopilar y hacer más accesible a la ciudadanía europea el enorme patrimonio cultural existente. In , Antoine Isaac, Robina Clayphan, and Bernhard Haslhofer explain how the metadata for over 23 million objects are being converted to an RDF-based linked data model in the European Union's flagship digital cultural heritage initiative.

Linked data vocabulary management

Publicado por Pablo Hermoso de Mendoza González

26/02/2013

Este artículo forma parte de la publicación de NISO (The National Information Standards Organization) referida a los estándares que se están instrumentando en las instituciones de la memoria: Archivos, bibliotecas y museos en su relación con linked data. En concreto este artículo versa sobre la gestión de los vocabularios en linked data. The article describes the shift in popular approaches to large-scale metadata management and interoperability to the increasing use of the Resource Description Framework to link bibliographic data into the larger web community. The authors also identify areas where best practices and standards are needed to ensure a common and effective linked data vocabulary infrastructure.

NISO Publishes Themed Issue of Information Standards Quarterly on Linked Data for Libraries, Archives, and Museums - National Information Standards Organization

Baltimore, MD - September 10, 2012 - The National Information Standards Organization (NISO) announces the publication of a special themed issue of the Information Standards Quarterly (ISQ) magazine on Linked Data for Libraries, Archives, and Museums. ISQ Guest Content Editor, Corey Harper, Metadata Services Librarian, New York University has pulled together a broad range of perspectives on what is happening today with linked data in cultural institutions. He states in his introductory letter, "As the Linked Data Web continues to expand, significant challenges remain around integrating such diverse data sources. As the variance of the data becomes increasingly clear, there is an emerging need for an infrastructure to manage the diverse vocabularie

Interpreting Data Mining Results with Linked Data for Learning Analytics: Motivation, Case Study and Directions. Matthieau D´Aquin. Nicolas Jay

Publicado por Pablo Hermoso de Mendoza González

25/02/2013

Learning Analytics by nature relies on computational information processing activities intended to extract from raw
data some interesting aspects that can be used to obtain insights into the behaviours of learners, the design of learning
experiences, etc. There is a large variety of computational techniques that can be employed, all with interesting properties, but it is the interpretation of their results that really forms the core of the analytics process. In this paper, we look at a speci c data mining method, namely sequential pattern extraction, and we demonstrate an approach that exploits available linked open data for this interpretation task. Indeed, we show through a case study relying on data about students' enrolment in course modules how
linked data can b...

A Survey of Semantic Web Technology in the Oil and Gas Industry

A Survey of Semantic Web Technology in the Oil and Gas Industry

This W3C Use Case present some significant applications of Semantic Web technology in the oil and gas industry, and describe  how the industry can leverage this technology. Ontology-driven information integration and delivery leverage rich extensible domain ontologies found in the oil & gas industry, and combine them with industry standard definitions and controlled vocabularies. This results in meaningful metadata that reflects the concepts relevant to the domain. This approach is extensible, as different domain ontologies can be linked together via common elements. As this approach is not hierarchical, there isn’t a single root. This means that new data and ontologies can be integrated with much flexibility, and the solution can grow incrementally. It also makes it eas...
