SemTech 2011 Coverage
Barbara H. Starr
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.
