Course description
This course will cover the central issues in word sense disambiguation.
We will start with the most important concern: what *is* a word
sense? We will discuss homonymy and polysemy (unrelated vs. related
senses), and issues such as word sense granularity and lexical
semantic relations. We will then review previous approaches to
distinguishing word senses, and how disambiguation relates to
different applications. We will also conduct exercises intended
to illustrate some of the difficulties with disambigation (both
in grouping word tokens into senses and in identifying dictionary
senses with tokens). The course will conclude with a discussion
on the coverage of machine-readable dictionaries and possibilities
for learning new senses automatically.
