Add schema.org Actions to Your Own Knowledge Graph (Video — Part 3)

[Editor's note: this is Part 3 of a series. See Part 1 and Part 2]

schema dot org logoIn Part 3 of this series, Jarek Wilkiewicz details activating the small Knowledge Graph (built on Cayley) with Schema.org Actions. He begins by explaining how Actions can be thought of as a combination of “Entities” (things) and “Affordances” (uses). As he defines it, “An affordance is a quality of an object, or an environment, which allows an individual to perform an action.”

For example, an action, might be using the “ok Google” voice command on a mobile device. The even more specific example that Wilkiewicz gives in the video (spoiler alert) is that of using the schema.org concept of potentialAction to trigger the playing of a specific artist’s music in a small music store’s mobile app.

To learn more, and to meet Jarek Wilkiewicz and his Google colleague, Shawn Simister, in person, register for the Semantic Technology & Business Conference where they will present “When 2 Billion Freebase Facts is Not Enough.”

New Open Source Graph Database Cayley Unveiled (Video – Part 2)

Barak Michener, Software Engineer, Knowledge NYC has posted on the Google Open Source Blog about “Cayley, an open source graph database.”: “Four years ago this July, Google acquired Metaweb, bringing Freebase and linked open data to Google. It’s been astounding to watch the growth of the Knowledge Graph and how it has improved Google search to delight users every day. When I moved to New York last year, I saw just how far the concepts of Freebase and its data had spread through Google’s worldwide offices. I began to wonder how the concepts would advance if developers everywhere could work with similar tools. However, there wasn’t a graph available that was fast, free, and easy to get started working with. With the Freebase data already public and universally accessible, it was time to make it useful, and that meant writing some code as a side project.”

The post continues: “Cayley is a spiritual successor to graphd; it shares a similar query strategy for speed. While not an exact replica of its predecessor, it brings its own features to the table:RESTful API, multiple (modular) backend stores such as LevelDB and MongoDB, multiple (modular) query languages, easy to get started, simple to build on top of as a library, and of course open source. Cayley is written in Go, which was a natural choice. As a backend service that depends upon speed and concurrent access, Go seemed like a good fit.”

How to Build Your Own Knowledge Graph (Video – Part 1)

Photo of Jarek WilkiewiczStraight out of Google I/O this week, came some interesting announcements related to Semantic Web technologies and Linked Data. Included in the mix was a cool instructional video series about how to “Build a Small Knowledge Graph.” Part 1 was presented by Jarek Wilkiewicz, Knowledge Developer Advocate at Google (and SemTechBiz speaker).

Wilkiewicz fits a lot into the seven-and-a-half minute piece, in which he presents a (sadly) hypothetical example of an online music store that he creates with his Google colleague Shawn Simister. During the example, he demonstrates the power and ease of leveraging multiple technologies, including the schema.org vocabulary (particularly the recently announced ‘Actions‘), the JSON-LD syntax for expressing the machine readable data, and the newly launched Cayley, an open source graph database (more on this in the next post in this series).

Building The Scientific Knowledge Graph

saimgeStandard Analytics, which was a participant at the recent TechStars event in New York City, has a big goal on its mind: To organize the world’s scientific information by building a complete scientific knowledge graph.

The company’s co-founders, Tiffany Bogich and Sebastien Ballesteros,came to the conclusion that someone had to take on the job as a result of their own experience as researchers. A problem they faced, says Bogich, was being able to access all the information behind published results, as well as search and discover across papers. “Our thesis is that if you can expose the moving parts – the data, code, media – and make science more discoverable, you can really advance and accelerate research,” she says.

Big Data Startup Roletroll Disrupts Job Search

roletroll

New York, NY, June 20, 2014 –(PR.com)– Former Wall St trader Adam Grealish launches Roletroll.com, a job recommendation engine for finance and tech jobs. The site uses unstructured data and statistics, collectively known as big data, to match users with jobs based on their unique skills and experiences.

 

Roletroll is a Brooklyn, NY-based start-up serving New York, Chicago and San Francisco. Job seekers upload their resumes, and computer programs do the job-search grunt work for them, aggregating jobs from multiple sources and identifying jobs that are a particularly good fit. Already Roletroll has scored over 5 million individual job matches. Read more

Semantic Tech Takes On Grants Funding, Portfolio Management

octoimageWhether the discussion is about public grants funding or government agencies’ portfolio management at large, semantic technology can help optimize departments’ missions and outcomes. Octo Consulting, whose engagement with the National Institutes of Health The Semantic Web Blog discussed here, sees the issue in terms of integration and aggregation of data across multiple pipes, vocabularies and standards to enable grant-makers or agency portfolio-managers to get the right answers when they want to search to answer questions, such as whether grants are being allocated to the right opportunities and executed properly, or whether contracts are hired out to the right vendors or licenses are being duplicated.

Those funding public grants, for instance, should keep an eye on what projects private monies are going to, as well – a job that may involve incorporating data in other formats from other public datasets, social media and other sources in addition to their own information, in order to optimize decisions. “The nature of the public grant market is effectively understanding what the private grant market is doing and not doing the same thing,” says Octo executive VP Jay Shah.

New Startup Skymind Offers Support for Open Source Deep Learning

 

Derrick Harris of GigaOM reports, “A San Francisco-based startup called Skymind launched on Monday to offer support and services for deeplearning4j, an open source deep learning project it has created. It’s early to tell how much traction deep learning will gain among mainstream companies or even web companies, but the technology does hold a lot of promise. The existence of open source libraries backed by professional services could certainly help spur adoption – especially for a field of data analysis previously relegated to top universities and research labs at companies such as Google, Microsoft, Facebook and Baidu.” Read more

Opinions Splitting Around the World on Data Protection & Net Neutrality

8347363864_3afc816567Karlin Kellington of The Irish Times reports, “In the wake of recent European Court of Justice decisions on privacy, and ongoing, divergent debates in the US and EU over net neutrality and copyright, are we about to end up with two markets divided by legislative approaches to the internet? Many think the possibility is growing of two differing jurisdictions, which will offer headaches and more complexity. However, there could be fresh opportunity for European businesses, too. The April decision by the ECJ to throw out Europe’s 2006 Data Retention Directive as well as the more recent ruling that Google is a data controller subject to national data protection laws in Europe which also can be forced to remove limited types of content on request, indicated the EU will prioritise personal privacy over certain business or government security arguments.” Read more

Data.gov Turns Five

datagov

Nextgov reports, “When government technology leaders first described a public repository for government data sets more than five years ago, the vision wasn’t totally clear. ‘I just didn’t understand what they were talking about,’ said Marion Royal of the General Services Administration, describing his first introduction to the project. ‘I was thinking, ‘this is not going to work for a number of reasons.’’ A few minutes later, he was the project’s program director. He caught onto and helped clarify that vision and since then has worked with a small team to help shepherd online and aggregate more than 100,000 data sets compiled and hosted by agencies across federal, state and local governments.” Read more
