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

[Philip Alexiev]

Hi Mehnaz,

In our previous experience we have found that phrases which are shorter 
than 3 symbols are too ambiguous and carry little benefit to the IE 
process. That is why the gazetteer skips short labels on initialization. 
It is true that in some special cases they might be useful. That is why 
we have included a tool to customize the init process of the gazetteer. 
It is present in version 3 of the KIM platform.

If you provide some more info on the use case we will try to provide a 
good solution.

Greetings,
Philip
