Here's my summary of questions asked at the ACL 2005 WSD tutorial. Let's
see what the questions are at AAAI (tomorrow!). You are welcome to sign
up for this list, even if you didn't attend the tutorial. There has already
been a little discussion, and hopefully there will be more!

Subject: [advances_in_wsd] questions from acl 2005 wsd tutorial
To: [EMAIL PROTECTED]
Before too much more time passes, I wanted to get out the list of
questions
that came up during the ACL WSD tutorial that seemed to merit a bit more
explanation or investiation.
Below is my list of questions, based on notes taken during the tutorial -
we'll explore them one by one eventually, but for now I wanted to at least
get
the questions out there. If you have other questions, please feel free to
post
them, and if you think we have missed the point of an original question in
our restatement, please let us know and try to clarify what was intended!
Finally, and most importantly, if you feel you have an answer for one of
these
questions, please feel free to post it!
1) What is the evidence regarding the truth the contextual similarity
hypothesis
being true? This hypothesis says that words that occur in similar contexts
will
have similar meanings.
2) How can you recognize metaphor, and disambiguate it appropriately once
you know
that it has occurred? For example, if I say "the party was jumping", that
might
have a meaning that is more than the sum of the individual senses of the
words
party and jumping.
3) Related to metaphor, there is an interesting possible application for
word sense
disambiguation to be found in Message Tracking. It is relatively common
for metaphor
to be used to hide threatening or criminal language. For example, a
criminal might
say "meet me at the bakery and bring your fishing pole", when he means to
meet at
the bank armed and ready to commit robbery.
4) Is name discrimination as described in the tutorial the same thing as
"name
normalization" as used in the biolink community? Name discrimination was
presented
as the problem of determining which George Miller was referred to in a
particular
context. For example, George Miller developed WordNet, and George Miller
directed
Mad Max, refers to two different George Millers.
5) Is name discrimination really an instance of word sense disambiguation?
Our argument
was that it is, if you have a predefined inventory of underlying
identities, much like
we have an underlying sense inventory as defined in a dictionary to
provide the set of
possible word meanings that we use in wsd.
6) What are the details behind the simulated annealing algorithm of Cowie,
et. al?
7) How can you carry out evalauations of word sense disambiguation systems
that are
based on two different sense inventories, for example WordNet and LDCOE?
8) In response to 7), the suggestion was made that a higher level ontology
could be used
as a point of comparison, functioning in effect as an inter-lingual that
could provide
a mapping between different resources.
9) How could the topic and theme of a document be used as a constraint for
word sense
disambiguation?
10) Where can we find out more information about the features that have
been used in supevised
learning systems?
11) Should we think not only about performing word sense disambiguation,
but also recognizing
when ambiguity occurs and/or when it actually matters? For example, does
the distinction between
"bank" as a river shore versus a slope in a hill actually matter for
certain applications?
12) Does word sense disambiguation help in Information Retrieval?
13) Does word sense disambiguation help in Machine Translation?
So, those are the questions I have in my note that I felt might require a
bit more explanation or
discussion. Please feel free to answer, clarify, or add to this list!
Cordially,
Ted
