OpenCalais 4.3 Debuts With Key Updates to Tagaroo, SemanticProxy, and Gnosis

Calais (, powered by Thomson Reuters, announced that OpenCalais 4.3 offers an entirely new "News Names" feature and enhanced Social Tags. Sweeping 2010 upgrades also bring dramatic improvements in the Tagaroo plug-in for WordPress,, and the Gnosis browser plug-in.

The following are the latest upgrades:

  • Enhanced Social Tags for categorization; improved disambiguation; new entities, facts and events in English; and an entirely new feature called News Names.
  • By popular demand, the improved Tagaroo plug-in for WordPress gives users more control over the tagging process.
  • The URL submission tool, SemanticProxy, has been normalized to ensure that its results are identical with those you would get by programmatically submitting content to OpenCalais via the API. Additionally, it is now supporting JSONP. You can now specify a callback function when requesting results in JSON.
  • The Gnosis plug-in for Firefox now includes categorization of processed webpages in the sidebar and can sort entities by alphabetical order or according to frequency or relevance.
  • The OpenCalais Schema has been published in OWL, enabling OWL enthusiasts to apply ontology based tools on OpenCalais metadata.

The OpenCalais Web Service automatically creates rich semantic metadata for the content you submit-in well less than a second. Using natural language processing (NLP), machine learning, and other methods, Calais analyzes a document and finds the entities within it. But Calais goes well beyond classic entity identification and returns the facts and events hidden within the text as well. The tags are delivered to you; you can then incorporate them into other applications-for search, news aggregation, blogs, catalogs, etc.

The Calais initiative is sponsored by Thomson Reuters ( and built on ClearForest technology.
