Dear Dil,
a stop_word is a type of word that come very frequently in a text, meanwhile
it's not of a great significance. For instance, prepositions, coordinators,
determinants are stop-words. Those words are not pertinents for automatic
summerization or abstract for exemple, they are not useful for information
extracting neither. This means, in the case of abstracting, we need to
eliminate them in order to obtain the adequate key words or sentece that
describe the text.

Greetings,

In the Information Retrieval (IR) community, stop words are defined as
grammatical or function words. They have similar frequency pattern across ALL
documents of all domains and subjects and hence they are considered "useless"
for  search and retrieval purposes. These words are typically among the most
frequent in a document or a text collection.

Hope that clarified the mystery.
