Here are the examinations for last year's two 7.5hp courses. The examination this year will be larger than any of them, but smaller than the two combined.
The following things from these exams are not part of this course:
The conversion to Chomsky Normal Form (exercise 3c in the NLP exam 2010-12-20)
Python programming (exercises 1–3 in both NLTK exams)
Instead the following areas might be included:
POS tagging by HMM
Laplacian smoothing
Evaluation of other things than chunking
Probabilistic parsing
Feature structures
