    La Web Semántica y sus aplicaciones. Linked Data y su evolución

    En junio de 2013, Andrés Pedreño, fundador de la Biblioteca Virtual Miguel de Cervantes e impulsor como CEO de Universia (2000-2004), nos invitó a participar en UniMOOC, una plataforma de cursos gratuitos para emprendedores promovida por varias universidades españolas y grandes instituciones privadas.

    Ricardo Alonso Maturana, CEO de GNOSS, compartió con los alumnos de la Universidad de Alicante, en una sesión grabada, los motivos que le llevaron a la creación de GNOSS. Hizo un repaso de las principales caraterísticas que definen la Web Semántica y Linked Open Data, que son las tecnologías, estandares y herramientas utilizadas como base para la creación de GNOSS.

    En este artículo escrito por Harry Halpin, Ivan Herman y Patrick Hayes se analiza el uso de owl:sameAs a la hora de enlazar datos con datos pertenecientes a diversos datasets, en el marco del proyecto global Linked Open Data.

    Los autores afirman que la comunidad que trabaja en el marco del proyecto considera que owl:sameAs establece vínculos e identidades a veces incorrectas y plantea otros enfoques a la hora de definir la identidad. De hecho, owlsameAs puede ser considerado sólo un tipo de "vínculo de identidad, un enlace que declara que dos elementos son idénticos en una cierta manera.

    Plantean cuatro lecturas alternativas de owl:sameAs, dependiendo de los casos:

    • Same think As but referentially Opaque
    • Same Think As but Different Context
    • Represents
    • Very Similar to

    LODStories: Learning About Art by Building Multimedia Stories

    LODStories is an engaging application where people learn about art while constructing multimedia stories about art. LODStories mines the Linked Open Data cloud to discover interesting connections between artworks, artists, places and ideas. LODStories guides users to construct a storyboard that connects the entities in an interesting way. It then fetches text, images and videos that users can arrange to create a multimedia story, and finally constructs a narrated video that users can edit and then publish to tell their story. The process is fun, and students learn about art and its connection to the world they live in. The paper describes the architecture of the system and the algorithms to make the exploration entertaining and educational.

    Linked Data for Libraries (LD4L)

    Project wiki-space for the Linked Data for Libraries (LD4L) project. The project is a collaboration of the Cornell University Library, the Harvard Library Innovation Lab, and the Stanford University Libraries, and is funded by a nearly $1 million two-year grant from the Andrew W. Mellon Foundation.

    The goal of the project is to create a Scholarly Resource Semantic Information Store (SRSIS) model that works both within individual institutions and through a coordinated, extensible network of Linked Open Data to capture the intellectual value that librarians and other domain experts and scholars add to information resources when they describe, annotate, organize, select, and use those resources, together with the social value evident from patterns of usage.

    La Fundación Lázaro Galdiano ha creado, en colaboración con la empresa GNOSS, una web semántica que integra un buscador facetado para la Colección del Museo Lázaro Galdiano.

    El proyecto ha tenido como objetivo estructurar y representar semánticamente las obras de la colección de arte de la Fundación, de acuerdo con los principios de Linked Open Data, y valorizarlos para su uso educativo aprovechando las ventajas de las tecnologías semánticas de la plataforma GNOSS.

    La aplicación de la tecnología semántica ha hecho posible desarrollar un espacio digital con una selección de casi 6000 obras de más de 800 autores que integra búsquedas facetadas, generación de contextos educativos y culturales sobre las obras buscadas y sistemas de recomendación.

    Semantic Web – Smithsonian Libraries Blog

    Editor’s note: Rachel is an intern from the University of Maryland’s iSchool MLS program and has been with us for the past seven weeks. Her internship is coming to a close, so we’ve asked her to write a blog post to share what she has done as part of her internship. I have posted this on her behalf. In January, Joel wrote about our plans to present the Taxonomic Literature-2 (TL-2) dataset as Linked Open Data, allowing for greater searchability and reuse. The main focus of my internship was to identify and investigate other data elements that could be converted to Linked Open Data.

    The Getty Vocabularies: project to publish as Linked Open Data  (Getty Research Institute)

    The Getty has a project to publish as LINKED OPEN DATA their vocabuaries.

    In the LODLAM Summit 2013, they have said that, planning for the publication of all four Getty vocabularies as Linked Open Data (LOD) is well underway. It´s anticipated that the data will be publishing under the ODC_BY 1.0. license. They will begin with AAT and then move on to TGN, ULAN from AAT and TGN; and CONA from all three. They also intend to publish LOD versions of their lookup list (e.g., languages, roles, nationalities, place types, and bibliographic sources).

    http://www.getty.edu/research/tools/vocabularies/2_itwg_technical_update.pdf

    What is the history of the Getty vocabularies?
    Work on the AAT began in the late 1970s in response to a need expressed by art libraries, art journal indexing services, and catalogers of museum objects and visual resource collections for a controlled vocabulary to encourage consistency in cataloging and more efficient retrieval of information. While controlled headings and terminology were already common in the field of bibliographic cataloging, and thesauri for cataloging in the sciences was by then well established, the use of a thesaurus for indexing was not welcomed by art catalogers prior to the advent of computerized cataloging. The original core AAT terms were derived from scattered local lists and other sources, in consultation with a panel of experts in architecture and art. The AAT was first published, in print form, in 1990.

    Work on the ULAN began in 1984, when the Getty merged and coordinated controlled vocabulary resources for use by the J. Paul Getty Trust's many automated documentation projects. The AAT was already being managed by the Getty at this time, and the Getty attempted to respond to requests from Getty projects for additional controlled vocabularies for artists' names (ULAN) and geographic names (TGN). In 1987 the Getty created a department dedicated to compiling and distributing terminology. Although originally intended only for use by Getty projects, in response to requests from the broader community, the ULAN was first published in 1991, in print form, according to the tenets previously established for the construction and maintenance of the AAT.

    Work on the TGN began in 1987. Its development was informed by an international study completed by the Thesaurus Artis Universalis (TAU), a working group of the Comité International d'Histoire de l'Art (CIHA), and by the consensus reached at a colloquium held in 1991, attended by the spectrum of potential users of geographic vocabulary in cataloging and scholarship of art and architectural history and archaeology. The TGN was first published, on the Web, in 1997.

    Work on CONA began in 2004, when detailed discussions regarding the Getty Vocabulary Program compiling a vocabulary comprising unique numeric identifiers and brief records for art works was undertaken. CONA is scheduled to be available for user contributions in 2011; the online "browser" is scheduled to launch in early 2012.

    Planning for the publication of all four Getty vocabularies as Linked Open Data (LOD) is well underway. It´s anticipated that the data will be publishing under the ODC_BY 1.0. license. They will begin with AAT and then move on to TGN, ULAN from AAT and TGN; and CONA from all three.

    Radically Open Cultural Heritage Data on the Web

    What happens when hundreds of thousands of archival photos are shared with open licenses, then mashed up with geolocation data and current photos? Or when app developers can freely utilize information and images from millions of books? Like the web of documents that became the World Wide Web, a web of data is the goal of Linked Open Data.  This paper examines how a cultural, technological, and legal environment is enabling a growing ecosystem of open historical data.  We explore the fundamental elements of Linked Open Data, how a global community within libraries, archives and museums is beginning to play a critical role, and how we are moving toward broader adoption.
