The project elaborated below aims at reducing this time constraint, by 
providing an effective summarization of reviews in a manner suitable for 
users. Usage of MapReduce technique provided by MongoDB is highly 
emphasized for processing reviews. The summarization of reviews is 
limited to attributes that the potential customers might be interested while 
looking for the particular product. In this paper, the technique used for 
the same is described which substantially reduces time complexity when 
implemented
