Abstract:
Sentimental Analysis can be referred to the process of analyzing and determining the thought process of the writer based on their messages
on various social networking sites. Twitter is one of the most renowned social networking websites where user can read and post messages about a
person, an event, a product and the current happenings all over the world. These are normally 140-280 characters in length. In this system, tweets are
used as the raw data. The tweets are collected through Twitter API using a secret token. Then they are preprocessed using text mining package to
reduce the noise in the words. The score is computed for each pre-processed tweet using Dictionary-Based Approach. For positive tweets, the score is
1, for negative tweet the score is -1 and 0 for neutral tweet. The pre-processed tweets along with the scores are stored in CSV format for further
process. The train data and test data is provided in the ratio 60:40 to construct the classification model. After classificat ion, it is observed that -
Convolutional Neural Network is unformulated to compute the probability of the tweets. The system uses K-fold cross validation method to improve over
the holdout method. Finally, as the result the opinion of the sentiment related to the given tweets is predicted using probability of the positive tweets by
hybrid approach. This system produces a better performance measure when compared to other method
