A new survey is just out reporting on how people are using Facebook. Just over 300 users were randomly selected by Stone Temple Consulting to gain some insight into Facebook feature awareness.
While not a definitive study (nor is it touted as one), one finding of interest to Semantic Web Blog readers is this: Below one-third of users have even heard of Graph Search, its functional semantic search engine for discovering relationships between entities in users’ networks of friends. It’s recently expanded from enabling queries around people, places, photos and interests culled from people’s profiles or pages (books your friends liked, for instance, or photos they took in San Francisco) to include searches of status updates, photo captions, check-ins and comments. Of those who do know what Graph Search is, just over one-third said that they had used it.
It’s got to be a happy Thanksgiving for a number of tech companies that made their way to Deloitte’s recently-released Technology Fast 500. The 2013 ranking of the fastest-growing tech companies based in North America also has something to show for anyone who’s doubted that there’s money to be made taking advantage of semantic and other Web 3.0 concepts, a look at the list should show it’s time for the doubting to stop.
Have a look at some of the winners with their overall rankings:
#2 Acquia. Drupal claims the title of being the first mainstream content management system to support semantic web technology in its core. The Drupal-powered project Acquia was co-founded by Drupal creator Dries Buytaert to provide cloud, SaaS, and other services to organizations building websites on Drupal – and has on staff software engineer Stéphane Corlosquet, who had a big hand in bringing those semantic capabilities to Drupal’s core. In fact, Corlosquet spoke at the most recent SemTechBiz about Acquia as an example of a Drupal-powered project managing its content as Linked Data.
How can the semantic web help you participate in and celebrate Halloween this year? We trolled around and came up with a few ideas:
* Still haven’t found just the right costume yet for tonight’s festivities (for you, that is – we’re sure the kids have had theirs planned for some time). Perhaps you’re thinking hard about a do-it-yourself skeleton theme, but aren’t sure of the details for creating the most realistic effect? Well, if you head over to semantic search engine DuckDuckGo’s science goodies section, you’ll get a quick response on the number of bones in the human body, courtesy of Wolfram/Alpha computations. You can take it from there.
* OK, costume’s in check. Now how about what to do while wearing it?
Semantic search engine SenseBot might be a help here, pointing you to information it’s extracted from web pages and summarizing them in a, well, sensible way, as well as offering a cloud of the concepts it’s discovered for you to further narrow your agenda. The results can be a little off here and there, but it’s nice to have an option to further narrow a search, like one for adult activities to partake in on Halloween, to something more granular, like those designed for the “scare” factor.
Tom Simonite of the MIT Technology Review reports, “More than one billion people visit Facebook each month, mostly to see photos and messages posted by friends. Facebook hopes to encourage some of them to do a little work for it while they’re there. By asking people to contribute data—from business locations to book titles—and to check one another’s work, Facebook is building a rich stock of knowledge that could make its software smarter and boost the usefulness of its search engine. ‘We’re trying to map what the real world looks like onto Facebook so you can run really expressive and powerful queries,’ says Mitu Singh, product manager for Facebook’s entities team, a group charged with building a resource called the entity graph.” Read more
Photos your friends took in New York City. Restaurants in Chicago your friends have been to. People who like running and who live in Denver, Colorado. Friends of friends who are interested in ballroom dancing or hiking.
Facebook’s new Graph Search promises to find all those things, and more, for you. Mark Zuckerberg announced the new way to get really personal in your searches for people, photos, places and interests today at an event at the company’s headquarters in Menlo Park, Calif., and the company has put up an explanatory page on the new service here.
While it doesn’t mention Open Graph specifically, the protocol that lets apps model a person’s activities based on actions and objects, it makes sense that the app-specific actions it lets people share on Facebook are feeding into the new search feature.
As we close out 2012, we’ve asked some semantic tech experts to give us their take on the year that was. Was Big Data a boon for the semantic web, or is the opportunity to capitalize on the connection still pending? Is structured data on the web not just the future but the present? What sector is taking a strong lead in the semantic web space?
We begin with Part 1, with our experts listed in alphabetical order:
John Breslin, lecturer at NUI Galway, researcher and unit leader at DERI, creator of SIOC, and co-founder of Technology Voice and StreamGlider:
I think the schema.org initiative really gaining community support and a broader range of terms has been fantastic. It’s been great to see an easily understandable set of terms for describing the objects in web pages, but also leveraging the experience of work like GoodRelations rather than ignoring what has gone before. It’s also been encouraging to see the growth of Drupal 7 (which produces RDFa data) in the government sector: Estimates are that 24 percent of .gov CMS sites are now powered by Drupal.
Martin Böhringer, CEO & Co-Founder Hojoki:
For us it was very important to see Jena, our Semantic Web framework, becoming an Apache top-level project in April 2012. We see a lot of development pace in this project recently and see a chance to build an open source Semantic Web foundation which can handle cutting-edge requirements.
Still disappointing is the missing link between Semantic Web and the “cool” technologies and buzzwords. From what we see Semantic Web gives answers to some of the industry’s most challenging problems, but it still doesn’t seem to really find its place in relation to the cloud or big data (Hadoop).
Christine Connors, Chief Ontologist, Knowledgent:
One trend that I have seen is increased interest in the broader spectrum of semantic technologies in the enterprise. Graph stores, NoSQL, schema-less and more flexible systems, ontologies (& ontologists!) and integration with legacy systems. I believe the Big Data movement has had a positive impact on this field. We are hearing more and more about “Big Data Analytics” from our clients, partners and friends. The analytical power brought to bear by the semantic technology stack is sparking curiosity – what is it really? How can these models help me mitigate risk, more accurately predict outcomes, identify hidden intellectual assets, and streamline business processes? Real questions, tough questions: fun challenges!
Search engine Yandex this week added personalization capabilities for Eastern European users’ search results. It analyses their online behavior including their search history, clicks on search results, and language preferences for its suggestions.
Kaliningrad is the name of the latest edition of Yandex’ personalized search engine. It uses that information to make suggestions and rank search results individually tailored for each user, showing book lovers that do a search on Harry Potter links related to the books, while those who prefer movies get film-oriented link fare.
Semantic markup didn’t play a role in the development of the technology, Yandex technical product manager and developer advocate Alexander Shubin says. But it can be applied for future enhancements, he notes. The new personalization reportedly leverages Yandex’ machine-learning-based query and search results algorithms “Spectrum” and “MatrixNet” to train the results to users’ requirements.
That said, Yandex has been diving deeper into semantic web waters. Beyond taking advantage of sites using schema.org markup to improve the display of search results, Shubin provides this update: “We enhanced our markup validator to understand all the markup (Open Graph, schema.org, RDFa, microformats). It is universal now (as Google’s or Bing’s instruments).”
The Facebook Developer Blog recently announced that the company will be cutting back on Open Graph actions in an effort to reduce spam: “Over the past six months we’ve launched new channels, such as App Center with our improved recommendations engine, to drive distribution to the highest quality apps. As part of these ongoing updates, today we’re releasing improvements to how we present Open Graph stories in news feed and on timeline to drive growth and engagement to your app. In order to provide users with experiences that meet their expectations, we will no longer approve custom actions that publish stories as people consume content. These apps must use the appropriate built-in actions or create a different sharing experience. We are also deprecating a handful of features that led to low quality user experiences.”
Kim-Mai Cutler of TechCrunch noted, “Now apps must use authorized actions like ‘Listen,’ ‘Read,’ ‘Watch,’ ‘Like,’ or ‘Follow’ if they want to automatically publish into the ticker or news feed as they consume content. Developers can still create custom actions like ‘run’ or ‘cook’, but a user has to click a button in order for that activity to be shared. The company is also giving additional distribution to news feed updates that have locations or photos tied to them, since these stories can get 70 percent more clicks if they have decent visuals. Facebook’s Henry Zhang wrote that these stories can see up to 50 times more ‘Likes’ than other stories.”

Remember how search engines can show nice snippets in their search results thanks to the structured data that webmasters embedded in the HTML of their webpages (RDFa, schema.org, etc)? Additionally, Facebook gains insight about user’s interest through structured data on webpages (i.e. Open Graph Protocol). Now there is a new kid on the block: Twitter.
Twitter recently introduced Twitter Cards, a way to “attach media experiences to Tweets that link to your content.” By adding structured data embedded in the HTML of your webpage, “users who Tweet links to your content will have a ‘card’ added to the Tweet that’s visible to all of their followers.” Basically, Twitter will now have a bit more of information about your webpage in order to know how to make a nice snippet in a tweet.
