This is a networking model where each user can choose who can follow her and whom she wants to follow. We can find the users who are very active in the social networks and consider them as influential users. This research addresses on Temporal Twitter Ranking (TTRank) to rank the influential users in Twitter. We apply Twitter-LDA topic modeling method to find the users’ topical interests. The time interval is an important factor as users’ topical interest can change over time i.e. users’ have different degree of topical interests at different timeinterval. So we give more emphasize on users’ most recent tweets. Our proposed approach also considers the impact of “Follower Influence” and “Retweet Influence”. The top influential users have been detected across different time intervals based on all the above mentioned factors and classified as “Highly Influentia...

However, due to the lack of proper knowledge or deliberate activity of some cunning people, fake news is spreading more than ever. People in general, struggling to filter which news to trust and which one to discard. Even the sly people take advantage of the situation by spreading false news and misleading the people. Natural Language Processing, one of the major branch of Machine Learning, the wealth of research is remarkable. However, new challenges underpinning this development. Here in this work, Naive Bayes Classifier, a Bayesian approach of Machine Learning algorithm has applied to identify the fake news. We showed, besides the algorithms, how the wealth of corpora can assist to improve the performance. The dataset collected from an open-source, has been used to classify whether the news is auth...
