WSD
- Without consulting a dictionary, enumerate word senses for the
noun web. Use either a flat organization or a
hierarchy, as you feel most appropriate.
- Consult any English dictionary other than WordNet, and consult WordNet.
Compare and contrast the different characterizations of the
senses for web. Include specific reference to how
different resources (including your answer to the previous
question) treat homonymy and polysemy.
- In Manning and Schuetze section Section 7.3.4, the constraint
known as "one sense per discourse" (Yarowsky 1995) is stated as:
"The sense of a target word is highly consistent within any given
document". (You knew that already from having read the chapter,
though, right??) Do exercise 7.9, which asks you to explore the
validity of that constraint, particularly with regard to different
types of ambiguity such as homonymy versus polysemy. Instead of
constructing examples, I encourage you to do Web searching and
find examples.
