DBpedia Spotlight looks for ~3.5M things of unknown or ~320 known types in text and tries to link them to their global unique identifiers in DBpedia.
Go to our Demonstration page, copy+paste some text and play with the parameters to see how it works.
You can use our demonstration Web Service directly from your application.

--data-urlencode "text=President Obama called Wednesday on Congress to extend a tax break
for students included in last year's economic stimulus package, arguing

--data "confidence=0.2" \
--data "support=20"
