[antlr-interest] True natural language lexical analysis by ANTLR?

[Hasan Mushtaq]

   Hi there, 
 
I have a very im^portant question. I am required to do lexical anaysis
       of a text. That is i am provided with two files, one contains large text(from an article)
       and the other contains the keywords that i need to find in the article.
       example: 
       if keyword = method // present in the keyword file
       then i have to find all varriants of this keyword that are present in the text
       i.e.  
       i have to find methods, methodology, methodologies, method...
       that is all with the same roots. Also the other way around that is if the
       keyword is ionization then i need to find ionize, inonizing..etc
       
       I have gone through the tutorials getting an idea of how ANTLR works but i could'nt
       find out if my purpose could be acheived by ANTLR or not. Please let me know if this is
       possible by ANTLR. If it is where would i get all the grammer from. 
       
       2- Now let me make this a little more complex I have to also find multiple words
       like basic set = basics settings etc
       
       3- a little more I have to also find the synonyms.. i.e.
       
       if keyword= road
       then find highway, street, etc
       
       parts 2 and 3 are not important right now. please let me know if the first part is 
       possible or not and if yes how ong would it take and where should i start. Any help would be greatly apprecited.

       
       Best Regards
