“Webize” Your Data with JSON-LD

json-ld-button

Benjamin Young of Cloudant reports, “Data is often stored and distributed in esoteric formats… Even when the data is available in a parse-able format (CSV, XML, JSON, etc), there is often little provided with the data to explain what’s inside. If there is descriptive meta data provided, it’s often only meant for the next developer to read when implementing yet-another-parser for said data. Really, it’s all quite abysmal… Enter, JSON-LD! JSON-LD (JSON Linked Data) is a simple way of providing semantic meaning for the terms and values in a JSON document. Providing that meaning with the JSON means that the next developer’s application can parse and understand the JSON you gave them.” Read more

First of Four Getty Vocabularies Made Available as Linked Open Data

Getty Vocabularies - Linked Open Data logoJim Cuno, the President and CEO of the Getty, announced yesterday that the Getty Research Institute has released the Art & Architecture Thesaurus (AAT) ® as Linked Open Data. Cuno said, “The Art & Architecture Thesaurus is a reference of over 250,000 terms on art and architectural history, styles, and techniques. It’s one of the Getty Research Institute’s four Getty Vocabularies, a collection of databases that serves as the premier resource for cultural heritage terms, artists’ names, and geographical information, reflecting over 30 years of collaborative scholarship.”

The data set is available for download at vocab.getty.edu under an Open Data Commons Attribution License (ODC BY 1.0). Vocab.getty.edu offers a SPARQL endpoint, as well as links to the Getty’s Semantic Representation documentation, the Getty Ontology, links for downloading the full data sets, and more.

Linking Parliamentary Big Data for Political Research

Dan Jellinek of UK Authority recently wrote, “A two-year project using ‘big data’ computing techniques to link records of Parliamentary debates with other social data could be ‘transformative’ for political research, the UK academic leading the project has said. ‘Digging into Linked Parliamentary Data’ is one of 14 international projects to win a share of a £3m Digging into Data Award, an international competition to develop new ways of handling ‘big data’ in humanities and social science research. It will develop semantic search tools to analyse databases of political debates in the UK, Canada and the Netherlands from 1800 to the present, enhancing the study of issues such as the history of left-right ideological polarisation in powerful ways, according to its leaders.” Read more

Driving New Revenue with Geospatial Data

6559335071_dfd8201a41

Mark van Rijmenam of Big Data Startups recently wrote, “Geospatial data is data that identifies a geographic location on Earth, such as natural or constructed features, oceans, and more. The data is generally stored as coordinates and topology and can be mapped. Geospatial data is all around us and it is growing at a staggering pace of 20% per year. McKinsey Global Institute estimated that location data level stood at 1 petabyte in 2009, excluding data from RFID tags. Geospatial data is created by a vast array of different applications such as satellites, digital cameras, wearables, smartphones, radars, sensor networks, cars, trucks, trains and other transportation. With trends such as the quantified-self, the Internet of Things and the Industrial Internet the amount of geospatial data will grow exponentially in the coming years and you can harness this data to better serve your customers.” Read more

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.”

Google’s Growing Database of the World’s Information, and You

Google

Tom Simonite of the MIT Technology Review recently wrote, “For all its success, Google’s famous Page Rank algorithm has never understood a word of the billions of Web pages it has directed people to over the years. That’s why in 2010 Google acquired Metaweb, a company building a database intended to give computers the ability to understand the world. Two years later the company’s technology resurfaced as the Knowledge Graph. John Giannandrea, vice president of engineering at Google and a Metaweb cofounder, says that will lead to Google’s future products being able to truly understand the people who use them and the things they care about. He told MIT Technology Review’s Tom Simonite how a data store designed to link together all the knowledge on Earth might do that.” Read more

The Semantic Web And Data Privacy

Happy Data Privacy Day!

The semantic web community has done its share of thinking on the data privacy topic, as evidenced by events such as Privacy Online 2013 at the International Semantic Web Conference in Australia. Recognizing the impact of semantic technologies on privacy, the workshop aimed to focus on raising awareness that the technologies the semweb community is working on have global societal consequences as well as to raise the awareness of interconnections between the different communities that are involved in Web privacy and security.

If you haven’t had a chance to have a look before, today’s the perfect day to check out the papers that were accepted for that event, which you can access here.

Case Study Radio, Ep. 1: Business Value of Linked Data

SemanticWeb.com - Case Study Radio SemanticWeb.com today is launching a new podcast series, “Case Study Radio,” that focuses on stories of applications of Semantic Technologies. Our first episode, sponsored by Zepheira, features a conversation with Dr. Eric Miller.

During our 14 minute discussion, we briefly talk about “What is Linked Data,” and then quickly move on to discuss the nature of Linked Data and the general business value to organizations that have taken Linked Data approaches. Dr. Miller mentions several high-profile, successful implementations, and in future episodes, we will take a deeper look at similar case studies.

Open The Door To Bringing Linked Data To Real-World Projects

ld1Linked Data: Structured Data on the Web is now available in a soft-cover edition. The book, authored by David Wood, Marsha Zaidman, Luke Ruth, and Michael Hausenblas, and with a forward by Tim Berners-Lee, aims to give mainstream developers without previous experience with Linked Data practical techniques for integrating it into real-world projects, focusing on languages with which they’re likely to be familiar, such as JavaScript and Python.

Berners-Lee’s forward gets the ball rolling in a big way, making the case for Linked Data and its critical importance in the web ecosystem:“The Web of hypertext-linked documents is complemented by the very powerful Linked Web of Data.  Why linked?  Well, think of how the value of a Web page is very much a function of what it links to, as well as the inherent value of the information within the Web page. So it is — in a way even more so — also in the Semantic Web of Linked Data.  The data itself is valuable, but the links to other data make it much more so.”

The topic has clearly struck a nerve, Wood believes, noting that today we are “at a point where structured data on the web is getting tremendous play,” from Google’s Knowledge Graph to the Facebook Open Graph protocol, to the growing use of the schema.org vocabulary, to data still growing exponentially in the Linked Open Data Project, and more. “The industry is ready to talk about data and data processing in a way it never has been before,” he continues. There’s growing realization that Linked Data fits in with and nicely complements technologies in the data science realm, such as machine learning algorithms and Hadoop, such that “you can suddenly build things you never could before with a tiny team, and that’s pretty cool….No technology is sufficient in and of itself but combine them and you can do really powerful things.”
