    Este video de algo más de 5 minutos expresa las principales ideas del proyecto web www.mismuseos.net, un proyecto desarrollado por RIAM I+L LAB, pyme tecnológica española que trabaja en el campo de la web semántica.

    The main goal of Mismuseos.net is to present a case of exploitation of Linked Data for the G.L.A.M. community through innovative end-user applications built on GNOSS, a semantic and social software platform. Mismuseos.net is a free access semantic online solution for end-users that allows them to find and discover museums-related content, and also reach some related external information thanks to the correlation with other datasets. We currently have collections of seven Spanish museums, where users can browse over 15,000 pieces of art and 2,650 artists. The featured applications are: faceted searches, enriched contexts and navigation through graphs. The search engine enables aggregated searches by different facets and summarization of results for each successive search.

    Mismuseos.net obtains the information about cultural goods from the Europeana dataset and the online collections of public Spanish Museums. It also extracts and links data from additional datasets of the Linking Open Data cloud, either to supplement information or to generate enriched contexts: Dbpedia, Geonames and Didactalia (a GNOSS project with an index of more than 50,000 open educational resources).

    Long description:

    GOALS

    Mismuseos.net shows a case of exploitation of Linked Data for the G.L.A.M. community through innovative end-user applications built on GNOSS, a semantic and social software platform. In more detail, the project is guided by the following goals:

    • Put data to work: exploit public datasets and information on museums to generate benefits for users and improve the user’s experience thanks to the potential of the semantic web.
    • Link datasets both to enrich content and generate accurate contexts of information building a cultural and educational graph.
    • Connect cultural and educational worlds in a knowledge ecosystem.

    SEMANTIC SOFTWARE SOLUTION: MISMUSEOS.NET

    Mismuseos.net is a free access semantic online solution for end-users that allows them to find and discover museums-related content, and also reach some related external information thanks to the correlation with other datasets. Mismuseos.net structures, organizes and makes available to you, in accordance with the principles promoted by the Linked Data Project, an extensive catalog of artworks that museums publish on the Web. Moreover, it links the catalog with other existing LOD educational knowledge bases allowing the generation of educational contexts related to cultural goods.

    We currently have a collection of seven Spanish museums (a meta-museum), where users can browse over 15,000 pieces of art and 2,650 artists. These are the museums included until now: Museo Bellas Artes de Bilbao, Museo Reina Sofía, Museo del Prado, Museo Sorolla, Museo de la Fundación Lázaro Galdiano, Museo del Greco and Museo de la Biblioteca Nacional (Museum of the National Spanish Library).

    Datasets used: Europeana (CER.ES collection), Dbpedia, Geonames and Didactalia (GNOSS)

    Mismuseos.net uses several datasets and sources of information:

    • Europeana dataset, specifically the data from the CER.ES collection (CER.ES is the Digital Network of Collections of Spanish Museums), and the online collections of public Spanish Museums. These two datasets were used in order to obtain the information about cultural goods (pieces of arts and museum information basically).
    • DBPedia, used to supplement the information about the author with and extract information on authors and museums location.
    • Geonames, in order to obtain the geolocation data of artists and museums, once we have obtained the names of the places from the primary source or from Dbpedia. This information will be exploited in the future to locate them in a map view.
    • Didactalia, an index of over 50,000 educational resources on gnoss.com, linked to provide users with related educational content.

    To sum up the process, the primary information has been enriched, cleaned and normalized when necessary, and uploaded to the project online space inside the gnoss.com platform, so that we can consume and exploit the data and present the end-user applications. We have prepared a general navigation through tabs that includes a homepage with content selection, a tab for the collection (pieces of art) and another one for artists. In the near future, we will also include a tab for museums. The previous entities (pieces of art, artists and museums) are represented on the platform with their specific ontologies thanks to the semantic CMS of GNOSS using standard vocabularies if available.

    Technology and main features:

    The solution has been developed on gnoss.com, a social and semantic platform with a deep focus on the generation of social knowledge ecosystems and end-user applications in a Linked Data environment. It includes faceted searches, recommendation systems and adapted contexts in education, university and enterprises. GNOSS could be conceived as a network of networks or a linked networks space oriented to using semantic technologies for data and service integration. Moreover, it has a wide range of configurable social tools, which have been mostly deactivated in the case of Mismuseos.net.

    • Semantic Content Management System (SemCMS): semantic forms engine

    GNOSS expresses user-generated content as structured data with default basic semantic standard vocabularies. This is done automatically when a user shares content on the platform. Besides, GNOSS has an engine for developing specific ontologies to represent knowledge objects, and, as a consequence, specific search engines if necessary. The semCMS allows uploading an OWL file describing the concepts and relations within a particular knowledge domain, and it generates a semantic form with all the classes and properties represented in the OWL file. This is the case of MisMuseos.net, which has ontologies with particular vocabularies for artworks, artists and museums. So, all the information is available in RDF files.

    • Faceted searches

    Mismuseos.net has a powerful faceted search engine that is generated by its semantic graphs (RDF triplets); the search engine exploits that graphs through reasoned or inference-based searches. It provides specific configurable facets for each item type. For instance, in the case of pieces of art, users can search by facets such as collection type (sculpture, drawing, painting, etc.), museum, key words, author, time period, art techniques, etc.

    By selecting a search option, it allows you to filter the results in consecutive searchers, and therefore restrict the results to a manageable number of entries. It offers summarization of the results, so that users can better understand how the results relate to all search facets. The values are recalculated for every set of results in aggregated searches. Also, one can only filter by those options where there results, avoiding incoherent search options.

    • Contexts or related information: enriched content in Mismuseos.net

    In Mismuseos.net, we have set several contexts depending on the object or entity that the user is viewing, which offer dynamically generated content:

    1. Contexts for the entity ‘piece of art’: related works by the same artist and artworks within the same particular time period (internal), artist information (internal); related educational resources of Didactalia (external, on gnoss.com).

    2. Contexts for the entity ‘artist’: artworks of the artist (internal), contemporary artists (internal), related paper toys and educational resources of Didactalia (external).

    GI2MO. Gestión de Ideas Semánticamente Mejorada - Semantically Empowered Idea Management

    El objetivo principal del proyecto GI2MO es la construcción de una ontología que modele los Sistemas de Gestión de Ideas. Además, se estudiará la aplicación del esquema de datos en sistemas existentes, usándolo para conseguir beneficios reales y medibles.

    El proyecto GI2MO considera que el término Gestión de Ideas se relaciona con sistemas dedicados a la organización y evaluación de grandes cantidades de inputs en forma de ideas, desde sitios diferentes; sobre todo contenido textual describiendo innovaciones relacionadas con ciertos productos.

    GI2MO pretende mejorar los actuales sistemas de Gestión de Ideas proporcionando mejoras en la capacidad de integración y en las herramientas de análisis de datos, a través de descripciones ricas en metadatos. Estas dos mejoras se derivan del uso de tecnologías de la Web Semántica, que interconectan datos dentro de los sistemas de Gestión de Ideas con informaciones proporcionadas por otros sistemas o por la Web

    Tutorial: How to Publish Linked Data on the Web. Como publicar datos enlazados en la Web. Videolectures.net.

    Aunque ya tiene 2 años, es una interesante presentación, en 2 vídeos de 90 minutos cada uno, en la que participan algunos de los más activos promotores de Linked Data. Tuvo lugar en la 7th International Semantic Web Conference, celebrada en Karlsruhe.

     

    La web es, de manera creciente, no sólo un espacio de información global basada en documentos enlazados, sino también un espacio de Datos Enlazados (Linked Data). Los principios de Linked Data proporcionan una base para construir la Web de los Datos o Web Semántica. Según la Web de los Datos Enlazados se extiende, se necesitan y se desarrollan aplicaciones para explotar estos conjuntos de datos. Por tanto, hay una necesidad creciente de publicadores de datos, investigadores, desarrolladores y expertos en la Web que comprendan y exploten los Datos Enlazados. Este tutorial es un buen punto de partida. Los ponentes son:

    Tom Heath, Talis 
    Michael Hausenblas, DERI Galway, National University of Ireland, Galway 
    Chris Bizer, Free University 
    Richard Cyganiak, DERI Galway, National University of Ireland, Galway 
    Olaf Hartig, Department of Computer Science, Humboldt University of Berlin

    Semantic Web Standards Wiki

    W3C cuenta con un nuevo sitio Wiki, llamado "Semantic Web Standards Wiki" (SWSWiki). No es su objetivo superponerse a otras comunidades Wiki como Semanticweb.org o WLED Wiki;sino proporcionar un punto de partida para tener más información sobre las tecnologías de la Web Semántica, en particular sobre los Estándares de la Web Semántica del W3C.

    A new public wiki site has been set up at W3C, nicknamed “Semantic Web Standards Wiki” or SWSWiki. It is not the goal of this wiki to supersede other community wikis like Semanticweb.org or OWLED Wiki; instead it is to provide a “first stop” for more information on Semantic Web technologies, in particular on Semantic Web Standards published by the W3C. Communities around such standards are also welcome to use the Wiki for their purpose; as an example, and thanks to Antoine Isaac, the SKOS community has already begun creating its own specific pages. Essentially, the role of this Wiki is to be an alternative (and, at some point in the future, maybe a replacement) to the ESW Wiki at W3C, but concentrating on Semantic Web only and using Semantic Media Wiki as an underlying technology.

    In addition to the classic “Web of documents” W3C is helping to build a technology stack to support a “Web of data”, the sort of data you find in databases. The ultimate goal of the Web of data is to enable computers to do more useful work and to develop systems that can support trusted interactions over the network. The term “Semantic Web” refers to W3C’s vision of the Web of linked data. Semantic Web technologies enable people to create data stores on the Web, build vocabularies, and write rules for handling data. Linked data are empowered by technologies such as RDF, SPARQL, OWL, and SKOS.

    Rhizomik

    tipo de documento Página Web

    La iniciativa Rhizomik es un proyecto está liderada por el grupo de investigación  GRIHO (Human-Computer Interaction and data integration), fundado por el profesor Jesús Lorès. El grupo orienta su trabajo a la mejora de la experiencia de las personas en el uso de la tecnología, esto es, en su interacción con las computadores y los sistemas. En este marco ha desarrollado un trabajo de investigación consistente en el marco de la web semántico. Rhizomik expresa el conjunto de proyectos que de manera concreta expresan ese trabajo.

    Ellos dicen de sí mismos:


    "The Rhizomik initiative is inspired by the rhizome metaphor when working with knowledge from a scientific, technological but also philosophical point of view.

    This metaphor has accompanied us in our research about knowledge in many different fields, fundamentally Semantic Web, Human-Computer Interaction, Web Science, Complex Systems and Cognitive Science.

    It has been materialised in the following projects:

    • Rhizomer: a tool to build Semantic Web-powered sites like this one
    • ReDeFer: a set of tools to move data in an out of the Semantic Web...
      • From RDF to HTML or SVG
      • From XML and XML Schemas to RDF and OWL ontologies respectively
    • Ontologies
      • Copyright: an ontology formalising the copyright core concepts
      • Multimedia: an ontology for the whole MPEG-7
      • E-Business: ontologies for some standards like XBRL, ebXML or BPEL-WS
      • News: ontologies for IPTC and MPEG-21 Digital Items
    • Semantic DRM System: a prototype of a copyright management system based on the Copyright Ontology
    • Living Semantic Web: an study of the Semantic Web as a complex system that shows that behaves like some living systems".
