Linked Data at the US Dept. of Veterans Affairs – Case Study Radio, Ep. 2

SemanticWeb.com - Case Study RadioOur podcast series, “Case Study Radio,” sponsored by Zepheira, focuses on stories of applications of Semantic Technologies. In the latest episode, we speak with Ramanathan “R.V.” Guha about a project at the United States Department of Veterans Affairs that utilized Linked Data and the schema.org vocabulary to develop a mechanism by which returning veterans can find employment opportunities. The work was originally announced in 2011 by schema.org and the White House, and has seen significant growth and adoption in the time since that announcement.

Scott Brinker presents “A NEW BRAND OF MARKETING” (Free eBook)

Click to dowload Scott Brinker's "A NEW BRAND OF MARKETING: The 7 Meta-Trends of Modern Marketing as a Technology-Powered Discipline"Scott Brinker, whom we have covered many times in the past because of his insights into semantic technology and marketing, has written a new short book about modern marketing trends.  The author presents “seven transformative meta-trends in modern marketing.” In the forward, he identifies these trends as “…wield[-ing] tremendous influence on the current evolution of marketing strategy and management.” The trends Brinker identifies are:

  1. From traditional to digital
  2. From media silos to converged media
  3. From outbound to inbound
  4. From communications to experiences
  5. From art and copy to code and data
  6. From rigid plans to agile iterations
  7. From agencies to in-house marketing

While he does not mention semantics explicitly in the book, knowing Scott as we do, we were curious about his thoughts on the subject. We caught up with him to ask, “So, how does this fit in with Semantic Web Technologies?”

Brinker responded, “Semantic web technologies are a great example of how technology is continuously changing what’s possible in marketing and business. But in the absence of ‘marketing technologists’ — these hybrid professionals who can translate technology capabilities to marketing opportunities, and vice versa — much of that potential remains untapped.”

“Structured and linked data can have such a tremendous impact on shaping customer experiences in a digital world. While not every marketer needs to understand the technical layer of how to make that happen, they need to have a sense of what’s possible — and they need to be able to work with more technical talent, as part of the modern marketing team, to make it happen.”

Brinker, who coined the term ”Chief Marketing Technologist,” is offering the 40-pager as a free download on his website.

 

194 Million Linked Open Data Bibliographic Work Descriptions Released by OCLC

OCLC WorldCat logoYesterday, Richard Wallis gave a peek into some exciting new developments in the OCLC’s Linked Open Data (LOD) efforts.  While these have not yet been formally announced by OCLC, they represent significant advancements in WorldCat LOD. Our reporting to date on LOD at WorldCat is here.

Most significantly, OCLC has now released 194 Million Linked Open Data Bibliographic Work descriptions. According to Wallis, “A Work is a high-level description of a resource, containing information such as author, name, descriptions, subjects etc., common to all editions of the work.” In his post, he uses the example of “Zen and the Art of Motorcycle Maintenance” as a Work.

RDF 1.1 is a W3C Recommendation

RDF 1.1Almost exactly 10 years after the publication of RDF 1.0 (10 Feb 2004, http://www.w3.org/TR/rdf-concepts/), the World Wide Web Consortium (W3C) has announced today that RDF 1.1 has become a “Recommendation.” In fact, the RDF Working Group has published a set of eight Resource Description Framework (RDF) Recommendations and four Working Group Notes. One of those notes, the RDF 1.1 primer, is a good starting place for those new to the standard.

SemanticWeb.com caught up with Markus Lanthaler, co-editor of the RDF 1.1 Concepts and Abstract Syntax document, to discuss this news.

photo of Markus LanthalerLanthaler said of the recommendation, “Semantic Web technologies are often criticized for their complexity–mostly because RDF is being conflated with RDF/XML. Thus, with RDF 1.1 we put a strong focus on simplicity. The new specifications are much more accessible and there’s a clear separation between RDF, the data model, and its serialization formats. Furthermore, the primer provides a great introduction for newcomers. I’m convinced that, along with the standardization of Turtle (and previously JSON-LD), this will mark an important point in the history of the Semantic Web.”

Constitute: Explore the World’s Constitutions with RDF

screen shot of constituteproject.orgIn the video below, Dr. James Melton, a Lecturer in Comparitive Politics at University College London, gives a presentation on Constitute. Constitute is a new way to explore the constitutions of the world. The origins of the project date back to 2005 with the Comparative Constitutions Project, which has the stated goal of cataloging the contents of all constitutions written in independent states since 1789. To date, that work has resulted in a collection of 900+ constitutions and 2500+ Amendments.  A rigorous formal survey instrument including 669 questions was then applied to each of these “constitutional events,” resulting in the base data that the team had to work with. Melton and his group wanted to create a system that allowed for open sharing of this information, and not just with researchers, but with anyone who wants to explore the world’s constitutions. They also needed the system to be flexible enough to handle changes, when, as Melton points out, “…roughly 15% of the countries in the world change their constitution every single year.”

Stardog 2.1 Hits Scalability Breakthrough

Stardog LogoWashington, DC – January 21, 2014 – The new release (2.1) of Stardog, a leading RDF database, hits new scalability heights with a 50-fold increase over previous versions. Using commodity server hardware at the $10,000 price point, Stardog can manage, query, search, and reason over datasets as large as 50B RDF triples.

The new scalability increases put Stardog into contention for the largest semantic technology, linked data, and other graph data enterprise projects. Stardog’s unique feature set, including reasoning and integrity constraint validation, at large scale means it will increasingly serve as the basis for complex software projects.

“We’re really happy about the new scalability of Stardog,” says Mike Grove, Clark & Parsia’s Chief Software Architect, “which makes us competitive with a handful of top graph database systems. And our feature set is unmatched by any of them.”

The new scalability work required software engineering to remove garbage collection pauses during query evaluation, which the 2.1 release also accomplishes. Along with a new hot backup capability, Stardog is more mature and production-capable than ever before.

New Vocabularies Are Now W3C Recommendations

W3C LogoWe reported yesterday on the news that JSON-LD has reached Recommendation status at W3C. Three formal vocabularies also reached that important milestone yesterday:

The W3C Documentation for The Data Catalog Vocabulary (DCAT), says that DCAT “is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web….By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable applications easily to consume metadata from multiple catalogs. It further enables decentralized publishing of catalogs and facilitates federated dataset search across sites. Aggregated DCAT metadata can serve as a manifest file to facilitate digital preservation.”

Meanwhile, The RDF Data Cube Vocabulary  addresses the following issue: “There are many situations where it would be useful to be able to publish multi-dimensional data, such as statistics, on the web in such a way that it can be linked to related data sets and concepts. The Data Cube vocabulary provides a means to do this using the W3C RDF (Resource Description Framework) standard. The model underpinning the Data Cube vocabulary is compatible with the cube model that underlies SDMX (Statistical Data and Metadata eXchange), an ISO standard for exchanging and sharing statistical data and metadata among organizations. The Data Cube vocabulary is a core foundation which supports extension vocabularies to enable publication of other aspects of statistical data flows or other multidimensional data sets.”

Lastly, W3C now recommends use of the Organization Ontology, “a core ontology for organizational structures, aimed at supporting linked data publishing of organizational information across a number of domains. It is designed to allow domain-specific extensions to add classification of organizations and roles, as well as extensions to support neighbouring information such as organizational activities.”
