This sample code shows how to use Markup entities and Disambiguated entities and how to use the Linked Data to get additional info on entities (how to retrieve information from the Linked Data end point).

Basically, the code sends a document to OpenCalais with RDF output format, and then analyzes the Companies, Geographies, Products, marked-up Companies, and the relevant disambiguated company URIs in the Linked Data. It outputs an xml file containing simplified data gathered from OpenCalais and Linked Data.

John David Anderson created this impressive mashup using the New York Times newswire API and OpenCalais, and won our recent mashup contest.

At ThoughtGlade.com, you can explore recent New York Times articles by clicking on their headlines toload up some basic NYT-supplied metadata about the article, followed by OpenCalais tagging of the article. Click on a tag name to explore the linked data associated with the tag (e.g., maps and related links). Since some tags are ambiguous (e.g., the dozen or more cities named "Washington") you may be first presented with a list of disambiguation options. This takes a bit more time to load. Click on one of the red disambiguation options to see the details.
