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)

Cayley Logo[Editor's note: This is Part 2 of a 3 part series. See Part 1 and Part 3]

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.

Content Rules In Search Engine Optimization

contentpixA couple of weeks back The Semantic Web Blog reported on research from SEO optimization vendor Searchmetrics about the virtues of semantic markup. Now the 2014 Content Search Marketers Survey, which recently came out from enterprise SEO platform vendor Brightedge, adds some more interesting statistics to show about what matters to optimized search.

Among them: Half of the respondents consider a page/content-based approach to driving page traffic, conversions and revenue as being much more important for SEO in 2014 than in 2013. Another 50 percent said it would be more or as important this year than last.

“The page-based approach to SEO in the world of secure search is important for 100 percent of SEOs, and 85 percent stated that it would be more or much more important for them in 2014,” the report states. “SEOs are also still focused on the business impact of the keyword (90 percent), though the shift in focus to the page leaves only 50% percent stating that measuring the business impact of the keyword will be more important in 2014.”

MindMeld Makes Context Count In Search

mmapiMindMeld – you may know the term best from StarTrek and those fun-loving Vulcan practices. But it lives too at Expect Labs, as an app that listens to and understands conversations and finds relevant information within them, and as an API that lets developers create apps that leverage contextually-driven search and discovery – and may even find the information users need before they explicitly look for it.

Anticipatory computing is the term Expect Labs uses for that. “This is truly a shift in the way that search occurs,” says director of research Marsal Gavaldà. “Anticipatory computing is the most general term in the sense that we have so much information about what users are doing online that we can create accurate models to predict what a user might need based on long-ranging history of that user profile, but also about the context.”

The more specific set of functionality that contributes to the overarching theme of anticipatory computing, he explains, “means that you can create intelligent assistants that have contextual search capabilities, because our API makes it very easy to provide a very continuous stream of updates about what a user is doing or where a user is.”

Schema.org, Semantic Search, and Your Web Page

Google Hummingbird

Barbara Starr of Search Engine Land recently wrote, “Although there has been some argument within the academic community that the Semantic Web ‘never happened,’ it is blatantly clear that Google has adopted its own version of it. Other search and social engines have as well — I wrote an article back in September 2012 discussing how search and social engines are adopting the Semantic Web and semantic search, and gave a timeline of the adoption of semantic search by both the search and social engines. It was very apparent, even then, that the search engines were moving in the direction of becoming answer engines, and that they were increasingly leveraging the Semantic Web and semantic search technology.” Read more

Musicians Can Now Include Official Tour Dates in Google Knowledge Graph

gwc

The Google Webmaster Central blog reports, “When music lovers search for their favorite band on Google, we often show them a Knowledge Graph panel with lots of information about the band, including the band’s upcoming concert schedule. It’s important to fans and artists alike that this schedule be accurate and complete. That’s why we’re trying a new approach to concert listings. In our new approach, all concert information for an artist comes directly from that artist’s official website when they add structured data markup.” Read more

Is A Knowledge Graph-Related Acquisition In Yahoo’s Future?

sdtechIs SindiceTech about to be acquired by Yahoo? Just last month The Semantic Web Blog reported on the formal relaunch of the company’s activities following the finalization of its separation from its university incubation setting at the former DERI institute in Ireland. Now, according to the Sunday Independent, Yahoo – which the article says had originally planned on buying the company late last year but saw negotiations collapse – may resume talks on the matter.

Yahoo, the article says, “refused to comment on the Sindice-Tech deal, calling it as ‘rumour and speculation.’” SindiceTech CEO Giovanni Tummarello also says that he cannot comment on this. He did note, however, that media, search and advertising are prime sectors for employing Knowledge Graphs. “In scenarios where there is much more (semi-structured) information than one knows how to leverage right away, Big Data graph-like knowledge management and moving from search to relational and entity search is a common theme these days,” he wrote in an email to The Semantic Web Blog.
