Paul Houle, founder of Ontology 2, says, “:BaseKB is an important milestone for both Freebase and the Semantic Web. :BaseKB opens Freebase to users of SPARQL and other RDF standards. The superior quality of Freebase data solves data quality problems that have, so far, frustrated Linked Data applications.”
Q: What do Google, Microsoft, Yahoo!, Yandex, the New York Times, and The Walt Disney Company have in common?
On June 2, 2011, schema.org was launched with little fanfare, but it quickly received a lot of attention. Now, almost exactly one year later, we have assembled a panel of experts from the organizations listed above to discuss what has happened since and what we have to look forward to as the vocabulary continues to grow and evolve, including up-to-the-minute news and announcements. The panel will take place at the upcoming Semantic Technology and Business Conference in San Francisco.
Moderated by Ivan Herman, the Semantic Web Activity Lead for the World Wide Web Consortium, the panel includes representatives from each of the core search engines involved in schema.org, and two of the largest early implementers: The New York Times and Disney. Among the topics we will discuss will be the value proposition of using schema.org markup, publishing techniques and syntaxes, vocabularies that have been mapped to schema.org, current tools and applications, existing implementations, and a look forward at what is planned and what is needed to encourage adoption and consumption.

Google announced they’re rolling out new enhancements to their search technology and they’re calling it the “Knowledge Graph.” For those involved in the Semantic Web Google’s “Knowledge Graph” is nothing new. After watching the video, and reading through the announcements, the Google engineers are giving the impression, to those familiar with this field, that they have created something new and innovative.
While it ‘s commendable that Google is improving search it’s interesting to note the direct translations of Google’s “new language” to the existing semantic web vocabulary. Normally engineers and researchers quote, or at least reference, the original sources of their ideas. One can’t help but notice that the semantic web isn’t mentioned in any of Google’s announcements. After watching the different reactions from the semantic web community I found that many took notice of the language Google used and how the ideas from the semantic web were repackaged as “new” and discovered by Google.
Google’s Knowledge Graph has been the subject of lots of attention over the past few days since the announcement. And the focus of a lot of questions, too.
There’s been discussion on chat boards, for instance, about just who’s gotten access and who hasn’t. In a discussion with a representative from Google, The Semantic Web blog has learned that, like many other new Google services, the roll-out is gradual, in order to ensure the system is handling new functions well. First-come, first-served are those who are signed into Google – but then again, not everyone who is signed in. But the plan is to have everyone who’s signed in on board over the next few days, the rep says; so if you are and don’t have it yet, it should be hitting your browser shortly. Those not signed into Google accounts probably have a week or two of a wait left. So far, the rep said that things have been pretty smooth, so Google’s going at the pace it was hoping to.
Red Bee Media, a company that “builds bridges between content and viewers” has posted a new article to their corporate blog regarding the growing volumes of television metadata. The article states, “TV Metadata is becoming increasingly rich and complex – powering increasingly advanced experiences. At a basic level, metadata tells us which programmes are available, and informs us about the content of those programmes. But metadata is getting richer and even bigger to support more visually engaging and functionally sophisticated user experiences.” Read more
Are you wondering why your product pages don’t stand out in search results like those from Amazon (shown below) or other competing e-commerce websites? These expanded results are commonly known as Rich Snippets (as named by Google) and are the result of having your HTML structured correctly with semantic markup. Whether you’re savvy to HTML5 and the latest design trends, or you haven’t updated your website code in years, this is article will explain why it’s important you structure your data properly utilizing semantic standards.
There are a number of ways to structure your data to make it more relevant to search engines, as well as social media sites. As an e-commerce retailer it is important to understand which of these standards you should consider including in your website. You should take some time to ensure you are implementing semantic markup, and doing it correctly. It has the power to better inform potential customers with upfront knowledge prior to landing on your site. Customers can see product reviews, pricing and stock information, and even images before clicking through to your website. This can lead to increased click-through rates, improve conversions, and generally enhance your SEO objectives.
Simply put, RDFa is another syntax for RDF. The interesting aspect of RDFa is that it is embedded in HTML. This means that you can state what things on your HTML page actually mean. For example, you can specify that a certain text is the title of a blog post or it’s the name of a product or it’s the price for a certain product. This is starting to be commonly known as “adding semantic markup”.
Historically, RDFa was specified only for XHTML. Currently, RDFa 1.1 is specified for XHTML and HTML5. Additionally, RDFa 1.1 works for any XML-based language such as SVG. Recently, RDFa Lite was introduced as “a small subset of RDFa consisting of a few attributes that may be applied to most simple to moderate structured data markup tasks.” It is important to note that RDFa is not the only way to add semantics to your webpages. Microdata and Microformats are other options, and I will discuss this later on. As a reminder, you can publish your data as Linked Data through RDFa. Inside your markup, you can link to other URIs or others can link to your HTML+RDFa webpages.

In October, BioBlitz 2011 took place in Tucson’s Saguaro National Park East and West. Thousands of volunteers worked together to discover the biodiversity of this marvelous place I call home. This blog entry outlines the work we’ve done the last few months, the reasons why BioBlitz matters (they might surprise you), and makes a call to photographers to help us test our crowdsourced image classification process.
The Team – National Geographic, National Park Service, Encyclopedia of Life, National Park Foundation
People from around the country worked hard to make BioBlitz successful. There were – and still are – a lot of moving parts. The Park is over 100 square miles, 70% of which is officially “wilderness,” which means, among other things, no wheels allowed! Read more
Users of Prestashop, the popular open source e-commerce package that powers over 100,ooo shops, now have easy access to semantic markup through the release of a free extension module from Makolab S.A. The extension adds markup from the GoodRelations vocabulary using RDFa syntax to the product item page templates. Read more
