    The Semantic Web provides an enticing vision of our online future. This next-generation Web will enable intelligent computer assistants to work autonomously on our behalf: scheduling our appointments, doing our shopping, finding the information we need, and connecting us with like-minded individuals.

    Unfortunately, the Semantic Web is also a vision that, to some, seems very distant, perhaps even outdated. It has been over a decade since it was popularized in a May 2001 article in Scientific American. Semantic Web researchers and engineers have been toiling even longer on the monumental technical and sociological challenges inherent in creating a global Semantic Web.

    The good news is that we are seeing evidence today of its accelerating emergence. Although still far from its grand vision, there are available today small “local” versions of semantic webs and intelligent assistants. Consumers can begin using these intelligent assistants today; producers can begin incorporating this next-generation semantic data into their current business models and applications.

    Paradoxically, the path to a global solution may evolve not only through the cooperation of a community, but through the selective forces of competition. As proprietary semantic networks and software agents vie for mass market dominance, winning technical and business models will emerge through a tapestry of data providers and services.

    YAGO es una gran base de conocimiento semántico, derivada de Wikipedia, WordNet, WikiData, GeoNames y otras fuentes de datos. Actualmente, YAGO identifica más de 17 millones de entidades (como personas, organizaciones, ciudades, etc.) y contiene más de 150 millones de datos sobre estas entidades.

    YAGO tiene una serie de propiedades de interés:

    •     La precisión de YAGO se ha evaluado manualmente, lo que demuestra una precisión confirmada del 95% (*). Cada relación está anotada con su valor de confianza.
    •     YAGO combina la taxonomía limpia de WordNet con la riqueza del sistema de categorías de Wikipedia, asignando las entidades a más de 350,000 clases.
    •     YAGO está anclado en el tiempo y el espacio. YAGO concede una dimensión temporal y una dimensión espacial a muchos de sus hechos y entidades.
    •     Además de la taxonomía, YAGO tiene dominios temáticos como "música" o "ciencia" de WordNet Domains.
    •     YAGO extrae y combina entidades y hechos de 10 Wikipedias en diferentes idiomas.

    YAGO se desarrolla conjuntamente en el grupo DBWeb en la Universidad Télécom ParisTech, el grupo de Bases de Datos y Sistemas de Información en el Instituto Max Planck de Informática y Ambiverse.

    Las Tecnologías Semánticas apuntalan la Inteligencia Artificial conversacional

    De manera discreta, las tecnologías semánticas se han convertido en un componente clave de la Inteligencia Artificial y otras aplicaciones de big data.

    Después de una larga hibernación, la Inteligencia Artifical ha despertado con energías para probar su valor en los negocios. Las tecnologías semánticas apoyan este resurgimiento, ayudanda a los usuarios a comprender textos, audios y relaciones entre los datos.

    Semantic Data Management in Practice Half-day Tutorial at WWW 2017

    After years of research and development, standards and technologies for semantic data are sufficiently mature to be used as the foundation of novel data science projects that employ semantic technologies in various application domains such as bio-informatics, materials science, criminal intelligence, and social science. Typically, such projects are carried out by domain experts who have a conceptual understanding of semantic technologies but lack the expertise to choose and to employ existing data management solutions for the semantic data in their project. For such experts, including domain-focused data scientists, project coordinators, and project engineers, our tutorial delivers a practitioner's guide to semantic data management. We discuss the following important aspects of semantic data management and demonstrate how to address these aspects in practice by using mature, production-ready tools:

    • i) storing and querying semantic data;
    • ii) understanding,
    • iii) searching, and
    • iv) visualizing the data;
    • v) automated reasoning;
    • vi) integrating external data and knowledge; and
    • vii) cleaning the data.

    2017 Trends for Semantic Web and Semantic Technologies - DATAVERSITY

    Article from Dataversity, published by By  , November 29, 2016.

    "Are you hearing the term “Semantic Web” as often as you may have in the past?  There’s no denying the importance of the technologies, standards, concepts, and collaborations that define the Semantic Web proper and all that is affiliated with it or grown out of it. [...] As we head into 2017, DATAVERSITY® wanted to follow up the state of the Semantic Web and Semantic technologies (both standards-body related and not)."

    Choosing Between Graph Databases and RDF Engines for Consuming and Mining Linked Data (Universidad Simon Bolívar, Caracas, Venezuela)

    Abstract.

    Graphs naturally represent Linked Data and implementations of graph-based tasks are required not only for data consumption, but also for mining patterns among links. Despite efficient graph-based algorithms and engines have been implemented, there is no clear understanding of how these solutions may behave on Linked Data

    The Graph Database and the RDF Database

    In a twist that has inevitable written all over it, the database industry has at last begun to take heed of the power of consumerization. The once mighty RDBMS is now obliged to make room for an emerging and increasingly important partner in the data center: the graph database. Twitter’s doing it, Facebook’s doing it, even online dating sites are doing it; what they are doing is tracing relationship graphs. After all, social is social, and ultimately it’s all about relationships.
