Breaking the problem down further

This past week or two I've been classifying each training example from Free917 based on how "easy" it is to answer. The only criteria is whether outside information is needed to answer the question, and an example where this is evident is the old Monopoly question: How old do you have to play Monopoly? To answer this question, not only does the computer need to know the meanings of all the words in this sentence, but also that "how old do you have to be" denotes that we are looking for some kind of "minimum age" of the Monopoly board game (information that does exist in Freebase). An example of an easy question would be something like "Who is the pitcher for the Chicago Cubs." The only information needed is Chicago Cubs and pitcher, which are both readily available; no extra intelligence is needed.

The label 1 means the question is easy, and 0 means it is not.

My other task is determining how to answer the "easy" questions, and at this point it seems the simplistic system I described a couple of posts ago can be adequate, with some tuning.
