Since the assertions were extracted from Web pages it's reasonable to assume that the answer doesn't exist because no one talked about textrunner prior to it being made public. That, or the sample of Web pages didn't contain any pages that referred to textrunner. Another possibility is the structure of the sentence(s) containing a reference to textrunner were not sufficiently simplifiable.

It's looking to fill in the sentence for you, so when you ask "What is awesome?" it returns "This CD is awesome!" and "This game is awesome".

Nobody has said "that band is textrunner!" ... or "{anything} is textrunner".

I really wonder what “high-quality Web pages” are. `What is Hacker News?` doesn’t give any results either.
