(a) First run using the version of the chunk patterns provided to you.
(b) Then run with the changes to the pattern set which you made for Assignment #4. Guided by the results, try making further changes to improve the score. Such improvements should have some generality ... not coded just to handle a specific example in the WSN article. (see the suggestions for Assignment #4 and the Noun Phrase section of the text.)
(c) Finally, to see if your changes are indeed general, run a second WSN article (with its key file) using both the original patterns and your current patterns. This file should be treated as test data -- you should not modify the patterns further after running with this data.
Submit your final pattern set and the scores you obtained for parts (a), (b), and (c).
2. (2 points) Rerun your experiment using the MUC named
entity tagger provided with Jet (command "tagNames"). This will
require small changes to the properties file and chunk patterns.
Your proper-name pattern should now look for ENAMEX annotations produced by
the NE tagger. Report your scores with the (otherwise) original
chunkPatterns and the chunkPatterns with your other modifications.
Include listings of the pattern files as modified to use the named
Due March 12th.
