Dear Sri Devendra Pratap Singh,

Thanks for your post and the query. Actually, the issue is the ability to devise synonymous terms (including BTs & NTs)  for a given set of Keywords. For instance, if you take a topic impact of politics in education, you see two keywords, POLITICS & EDUCATION.

Now for politics you can use

political ideologies,

Political violence

Political parties & so on

For Education you can use

Pedagogy

Learning process

Academia et. etc.

You can now understand that it depends upon your conception and stock of words to use them as vocabularies that means your ABILITY to use/GENERATE alternate synonymous terms to match your requirement.

These alternate terms used as alternative Keywords have great impact on the 'Relevance' & 'Recall Values' of  your search outputs.

Sincerely,

Siddhartha S. Ray, Calcutta

Dear Friend Devendra Pratap,

A very clear definition and step-wise clarifications/ideas has given by Siddhartha Shankar Ray Sir. It is just like total solution. Since we are infant in the profession, we may not have the comprehensive words/vocabularies in our bank (mind). So in this regard, I would like to direct you to refer the Library of Congress Subject Heading (LCSH) list or Sears List of Subject Headings(SLSH). In both the books(also called as library tool) you will find the controlled vocabularies/words of universe of subjects and its similar, best possible synonyms, written either in BT or NT. 

thanking you...
