[Kim-discussion] if a named entity is an instance of two classes?

[Mehnaz Adnan]

Hi Philip,


I am trying to provide semantic annotation for the medical abbreviations in
my text. For this case I want to use only short forms (eg. K) in IE process
and provide long forms( e.g potassium)  in popup window. For many cases I
have more than one long forms. As I am dealing with abbreviation so I  have
a lot of phrases having less than three symbols.

Please advice me a good solution.

Mehnaz
