This brings up the question of which algorithm is more optimal for the particular problem one is trying to solve. API to retrieve tweets using queries posed. SVM is one of the widely used supervised machine learning algorithms for textual polarity detection. 1. LTS models are the foundation for various automated verification techniques such as model-checking and model-based testing. Sentiment analysis is a technique used to analyze the attitude, emotions and opinions of different people towards anything, and it can be carried out on tweets to analyze public opinion on news, policies, social movements, and personalities. Twitter is a popular social networking website where users posts and interact with messages known as “tweets”. The ideas or opinions expressed there can be either encouraging or discouraging, i.e. Moreover, enhancements of LTSs inferred by ModifiedQSM and MarkovQSM learners are demonstrated by a series of experiments. The intensity of a review is determined using four measures containing knowledge and understanding, course contents, teaching style, and assessment procedures for a specific course. Moreover, MarkovQSM has proven to significantly reduce the number of membership queries consumed compared to ModifiedQSM with a very small loss of accuracy.
