Assignment 3
Assignment 2
Assignment 2 Sample Solutions:
Choose a text collection (one provided by NLTK, or any other you may want to
use; in the latter case you should run a POS tagger over it first).
Choose a verb that interests you, and find all the sentences that are tagged
with that verb (probably best to use all of its conjugated forms). Be sure you
have a good size number of sentences containing the verb in its various forms
(at least 30).
Using the NLTK shallow parsing facility (chunk, unchunk, and chink rules
along with RegexpChunkParser), produce shallow parsers of the selected
sentences. You may want to start with the ones that I presented in class, but
you should improve on them greatly. I suggest using multiple rules for each
type of chunk (NP, VP, PP, others if you like). When you turn in the assignment
you should show some before and after parses on the same sentences to show how
much your rule rewrites have improved the chunker.
Analyze the argument structure of the verb that you've chosen. What kinds of
subject and objects does it tend to take, both syntactically and semantically?
(Optional) Now try to find at least two verbs that take objects or subjects that are similar in
form, either syntactically, semantically, or both. If you can't find any, try
to describe why not. Be sure to describe how you tried to find the similar verbs.
You may want to use the functions that I discussed in class: chunking.py
Optional paper that has some good ideas:
VerbOcean: Mining the Web for Fine-Grained Semantic Verb Relations,
Chklovski & Pantel. EMNLP 2004.
pdf
To turn in:
- Samples of before-and-after parses of sentences using your improved rules
compared to those I've provided, and a description of your regexps.
- Your code in one or more files.
- A description of the characteristics of the context surrounding the verb,
answering the questions posed above.
- (Optional) A description of the verbs similar to this one that found (or if you
couldn't find them, say why not), and how you did this analysis.
