I'm having a hard time figuring out what type of data watson accepts: RDF triples, relational, delimited text, etc.
There's really no documentation anywhere.
Does anyone know?
Watson currently eats unstructured English Prose in HTML, Word Doc, Text, and certain formats of PDF.
Some API documentation can be found here: https://www.ibmdw.net/watson/wp-content/uploads/sites/19/2013/11/An-Ecosystem-Of-Innovation-Creating-Cognitive-Applications-PoweredByWatson.pdf
You can also get a bit more if you go to the bottom of the mobile developer challenge page that's here: ibmwatson.com (see 'Helpful Hints about Watson')
If there's other documentation you're looking for, specific feedback would be helpful to pass on
