Yes, I found the #topic item, but thank you for the script location and the one for #whereIs. Btw, do you know if the Freebase information will be moved to WikiData, as I read on it's Wikipedia entry that Google is discontinuing it.
The think() method is one I found in the Pandora.jar which in the JavaDocs states it "Look for P->Q state rules between vertices and their relationships." This was the closest I found to the pattern matching function. I wanted to look into how it operates a bit further.
I see the basic math uses a Calculator tool, and I don't see where #add is defined. I'm thinking it might be possible to define math operations using lingual relationships though. Your thoughts?
