Recently opinion Analysis gives extensive
contribution of Natural Language Processing (NLP) which
promises with the computational measures of opinion,
subjectivity and objectivity in the given sentimental text.
Opinion analysis is the mechanism of extracting meaningful
knowledge from the people’s review opinions, appraisals and
emotions toward specific entities, events and their respective
attributes. Many times these opinions drastically make
impact on consumers to choose their products and entities.
Some users watch movies according to rating given by bunch
of peoples. Thus, it is desired to develop an efficient and
effective sentiment analysis system for product buyer and for
movie reviewers based on bunch of people comments
regarding that particular product or movie. Here we consider
the positive, negative, neutral sentences along with some
special sentences in which negations words occur or a
sentence containing not only but also like structural
composition in the sentences which change the meaning of
total sentence. We found SentiWordNet dictionary to assigns
sentiment scores to each sentiment word found in comments.
Sentiment words are assigned three sentiment scores:
Positivity, Negativity and Objectivity with a word which lies
in between the range 0 to 1. The final opinion review
prediction uses Rule-Based and Fuzzy measures approach
and gives the final output.

Implementation of SA based system provides major
benefits to improve current market strategies so that
maximum benefits can be achieved by applying proper and
market suitable strategies. The major opinions sources
regarding film or any product are Web, Social Networking
web-sites for instance Orkut, Facebook and Twitter and
other many web services from where subject related
information can be gathered.
There are various challenge, more companies and
researchers are working in this area until one day it would
be easy for users and companies to minimally obtain
complete and wealthy summarized fact about the opinions
from the web in order to uphold them in the decision
making process in their daily life.
Our work gives idea regarding how document based
sentiment analysis implementation can be done by
applying rule based and fuzzy system to create decision
making system .
