I'm looking to automatically query for definitions of words. Can you please suggest some dictionaries I can use? My only requirements are that the dictionary is free, and something I can download and query from an already-existing Java/Python program. I've been using Wordnet and its glosses thus far, but I'm looking for an additional resource.
Also, I was told to take a look at WordWeb -- has any one had any experience with it?
Thank you for your help.
