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.

curl http://spotlight.sztaki.hu:2222/rest/annotate \
  --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
  that the policy provides more generous assistance." \
  --data "confidence=0.35"

or for JSON:

  --data "confidence=0.35" \
  -H "Accept: application/json"
