[Corpora-List] About multiple sense tags used in the answer key file of Senseval

[Adam Kilgarriff]

Dear Robin,

The trouble with word sense disambiguation is word senses. They just won't
behave.  

Sometimes, the best that a human can do is to say that a corpus instance is
related to more than one word sense (so it is tagged with multiple sense
tags) or that it is unassignable (U) or that it is like one of the senses in
one way but not in others (combination of U and one or more regular sense
tag.) This is the scheme we have used for English for all three Sensevals,
you can find descriptions in the SENSEVAL 1 Special Issue of Computers and
the Humanities 34 (1-2) amongst other places, here are links to papers that
discuss it

Subject: [Corpora-List] About multiple sense tags used in the answer key
file of Senseval



         Dear list memebers, I'm a research student doing research on NLP, 
word sense disambiguation in particular. I am planning to conduct 
experiment on the Senseval-3 data. But after reading the answer key file, 
one fact appears a bit confusing, sometimes for one test case, multiple
sense
tags are given, and one of the multiple sense tags could be simply a 
letter "U". I tried and looked into the documentation, but haven't found 
any relevant information.  Could anyone kindly tell me how to make sense 
of those multiple sense tag cases or probably point me to the relevant
documentation?


       Regards
       Robin.
