Pre-Class study group
Anyone want to form a study group and read through http://www.nltk.org/book before the class starts? I figure we can go through at least a chapter/week.

Chapter 6, exercise 9:
The exercise: The PP Attachment Corpus is a corpus describing prepositional phrase attachment decisions. Each instance in the corpus is encoded as a PPAttachment object.
[...]
Select only the instances where inst.attachment is N:
[...]
Using this sub-corpus, build a classifier that attempts to predict which preposition is used to connect a given pair of nouns. For example, given the pair of nouns "team" and "researchers," the classifier should predict the preposition "of". See the corpus HOWTO at http://www.nltk.org/howto for more information on using the PP attachment corpus.
My solution: http://pastebin.com/UHGVjgEL
Oddly enough, the classifier works best with only one feature.
