CS 5761 - Introduction to Natural Language Processing
"Programming" Assignment 6 - Due by 5pm Monday, April 1
(submit via email to firstname.lastname@example.org as plain text by deadline, no
demo required for this assignment)
To become familiar with WordNet, and the ideas of hyponomy, polysemy, and
Part I [5 points]
Rearrange the noun senses of five word that you shall select (based on
criteria described below) from the WordNet 1.7 lexical database so that
polysemous senses are distinct from homonyms.
For polysemous senses, explain how they are related. In some cases you
might need to add a "subsuming sense" if there is one that is not already
present in WordNet. However, in general you should avoid the addition
of new senses and simply rearrange existing ones. Your explanation should
be about a paragraph in length for each polysemous sense you identify, and
include a description and example of the polysemy that is present.
Choose 5 nouns that are distinct types and not synonyms. Each noun should
have at least 10 senses and require some rearrangement. There should be
at least two polysemous senses in the nouns you select.
Show your re-arranged version as if it were displayed by:
wn word -synsn -g
After each revised display, provide your explanation and examples for the
polysemous senses you identified.
Part II [5 points]
Select five sentences from the Brown corpus and identify the thematic
roles used in that sentence. Use the thematic roles as defined in Figure
16.8, page 609 of our text. The Brown corpus is available at:
Please copy the sentences you tag with thematic roles exactly from this
Policies (from syllabus)
All programming assignments and your project will be demonstrated during
designated lab sessions. You should also submit an electronic copy of
your source code to the TA prior to the designated demo session. (His
email address is email@example.com.) There is no other way to submit
your programming assignments or project. Failure to submit AND demo on
time will result in a zero.
Any code you submit should be commented. I must be able to understand
what your code does simply by reading the comments. This understanding
should extend down to the details of your code. So do not simply
describe the input and output, also include comments that describe
your particular algorithm and coding techniques. Failure to comment
to this degree will result in a zero.
All assignments and the project are to be done individually. You are
required to write your own code. Unless otherwise specified, you must
only turn in code that you personally wrote. The only possible exception
to this is if I tell you to use a module that is available in a book
or online archive. However, I will clearly indicate when this is
permissible. Violations of this policy will result in severe grading
penalties and/or failure in the class.
