Assignment 3 sample solutions

There are no full solutions for this assignment. You can download the function evaluate-distinctions together with the code I used in my evaluation lisp3eval.tgz .

For minipar evaluation, below is a list of problems originally enumerated by prof. Schubert as he was testing it

  • topicalization isn't handled
  • nominalized VPs and clauses aren't handled.
  • conjunctions are swallowed
  • for VPs with auxiliaries, the main verb features are propagated upward, instead of the head verb features.
  • complements are almost always misclassified as adjuncts, except for NP objects and that-clause objects. In particular PPs and even VP complements seem to be uniformly treated as adjuncts.
  • PP and ADVL gaps aren't recognized, even in wh-questions. In fact only NP gaps seem to be recognized.
  • right-node raising isn't handled

    Here's a sample writeup which got the full grade. It's not the longest one I received, and you will notice that it does not enumerate all the same problems, but I felt it satisfied several important points: it demonstrated that the student tried to parse the majority of constructs handled in class notes, it presented the conclusions clearly, and it gave the results in easy to read format: minipar.txt .
