Understanding of the feelings of human massages towards totally different entities and product, permits higher services for discourse advertisements and analysis of market trends. We tend to use machine learning classifiers to detect sentence polarity. Our input to classifier is tweets without Stopwords. Unigram method is used for feature selection. The classifiers we use are Bayesian network, Random Forest, and k-Nearest Neighbor. The differences between classification time of decision Bayesian network, Random forest and KNN are about an order of magnitude, based on accuracy. This study includes a brief introduction describing the area of application of opinion mining, and some definitions useful in the field. The most commonly used methods are mentioned and some alternative ones are described. Experiment results are presented which show that KNN algorithm gives best results than other algorithms.
