SemTech 2011 Coverage
In Barbara Starr’s (Ontologica) session this week at Semtech 2011, San
Francisco, she presented a detailed timeline outlining the adoption of RDFa and
semantic search enhancements by the major search engines. In addition to
mentioning the rapid growth of the Linked Open Data (LOD) cloud, she showed
a movement by the search engines, in particular Google, to support semantic
search. The movement is going away from a web of documents with hyperlinks to

a web of data and semantic links. Her timeline showed the evolution from search
engine support for structured data formats such as Resource Description
Framework-in-attributes (RDFa) through last week’s announcement of the
Schema.org alliance.

In her talk, she demonstrated how the use of semantic technology in commercial searches can be
accomplished by doing a query for “Barack Obama Birthday” on both Google and Bing. Google
returns answers from typical sources like answers.com and Wikipedia, as shown below in Fig. 1.0.

The same search performed on Bing, see Fig. 1.1 below, returns the same answer, but the
information is reported as being sourced from Freebase. Freebase is a semantic web company
recently acquired by Google.

structured markup. Starr presented a series of slides that outlined a timeline for Google, Yahoo!, &
Facebook’s support for rich snippets and structured data. Her timeline, shown below, is a good
outline of important semantic search adoptions since 2008.

Google, Yahoo!, and Bing announce Schema.org: June 2011
The recent Schema.org announcement further illustrates Starr’s point about the importance of web
developers learning to implement structured data into their websites and to consider the
optimization value of doing so.
The presentation concluded with a list of useful resources for developers to validate RDFa and demo
of a tool called Gruff, from Franz Inc., that allows developers to visually analyze RDFa markup in a
triple store.
Developers can verify their structured markup and learn more about RDFa at the following URLs:
•
RDFa official site: http://check.rdfa.info
•
Sindice Inspector: http://inspector.sindice.com
•
Yahoo! object finder: http://developer.search.yahoo.com/help/objectfinder
•
Google Rich Snippets Tester: http://www.google.com/webmasters/tools/richsnippets
Starr’s presentation clearly demonstrated the recent increase in adoption of structured data by
major search engines. Developers have plenty of resources and opportunities to include different
types of structured data in their web pages. The choice of types depends on the application and the
long-term goals of the developer.
