[Corpora-List] Automatic categorization of words.

[Cyrus Shaoul]

Dear List,

I have been lurking for a while, but decided to post my first question
to the list today. I am trying to do research on the differences between
  concrete and abstract words (ie: "rock" and "justice").

Does anyone know of any research or tools related to automatically
categorizing words into these types of categories (also called
imageability levels) based on corpus analysis?

Thanks in advance,
