Hi Mehnaz,<br>
<br>
My opinion is that because of the great ambiguity of short literals and
abbreviations the results will be quite noisy. You could try and do
some experimenting. For that purpose you can use a standard Gate
gazetteer and make a list with the abbreviations you want to recognize.<br>
<br>
One thing that could increase the precision of the IE process is to
take into consideration the context of the abbreviations. This is best
achieved by the use of pattern matching of annotations and Jape
grammars.<br>

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. </div>

<div>Please advice me a good solution.<br>

<div text="#000000" bgcolor="#ffffff">Hi Mehnaz,<br>
<br>
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.<br>
<br>
If you provide some more info on the use case we will try to provide a
good solution.<br>

<div text="#000000" bgcolor="#ffffff">Hi Mehnaz,<br>
<br>
It is conceptually incorrect to have instances of more than one class.
My advice is to fix the model and not hack the recognition.<br>
<br>
About the second question, it is strange to me that you don't want the
complete name of the abbreviation recognized. A solution I would
recommend, is to use the rdfs:comment property to describe the full
alias. It will be shown as a description of the entity in the KB
Explorer (popup window) and will not be used in the information
extraction process. Another way is to use your custom property, which
will be displayed in the list of properties for that entity.<br>
<br>
Hope this helps,<br>
