A great demand of sentiment classification comes with the rapid development of the internet. At present, the methods about sentiment classification based on machine learning have been widely used. The sentiment classification is a more difficult task, which needs more in-depth study than the traditional topic-based classification method [1]. Naïve Bayesian classifier is widely used in text classification. However, it requires two basic assumptions as its prerequisite and the performance would have been poor if these two were dissatisfied. We propose a multi-level naïve Bayes classifier to make up the deficiency of the traditional naïve Bayes classifier. The research below shows that the multi-level naïve Bayes classifier gets better performance than the traditional naïve Bayes classifier on the sentiment classification of movie reviews.

Arrangement highlights were gotten from the substance of each tweet, including syntactic conditions between words to perceive "othering" phrases, actuation to react with adversarial activity, and cases of very much established or legitimized oppression social gatherings. The consequences of the classifier were ideal utilizing a blend of probabilistic, rule-based, and spatial-based classifiers with a casted a ballot group meta-classifier. We show how the consequences of the classifier can be powerfully used in a factual model used to figure the probably spread of digital scorn in an example of Twitter information. The applications to strategy and dynamic are examined. We propose a cooperative multi-space assessment arrangement way to deal with train supposition classifiers for numerous areas at the same time. In our methodology, the supposition data in various spaces is shared to prepare more precise and vigorous notion classifiers for every area when named information is scant. In particular, we decay the slant classifier of every space into two segments, a worldwide one and an area explicit one. The area explicit model can catch the particular feeling articulations in every space. Moreover, we extricate Tri_Model (Naive Bayes IBK, SVM) sentiment information from both marked and unlabelled examples in every area and use it to upgrade the learning of Tri_Model (Naive Bayes IBK, SVM) sentiment classifiers.

The quality of an airline's services cannot be measured from the company's point of view, but must be seen from the point of view of customer satisfaction. Data mining techniques make it possible to predict airline customer satisfaction with a classification model. The Naïve Bayes algorithm has demonstrated outstanding classification accuracy, but currently independent assumptions are rarely discussed. Some literature suggests the use of attribute weighting to reduce independent assumptions, which can be done using particle swarm optimization (PSO) and genetic algorithm (GA) through feature selection. This study conducted a comparison of PSO and GA optimization on Naïve Bayes for the classification of Airline Passenger Satisfaction data taken from www.kaggle.com. After testing, the best performance is obtained from the model formed, namely the classification of Airline Passenger Satisfaction data using the Naïve Bayes algorithm with PSO optimization, where the accuracy value is 86.13%, the precision value is 87.90%, the recall value is 87.29%, and the value is AUC of 0.923.

Classification is the process of grouping objects that have the same features or characteristics into several classes. The automatic documents classification use words frequency that appears on training data as features. The large number of documents cause the number of words that appears as a feature will increase. Therefore, summaries are chosen to reduce the number of words that used in classification. The classification uses multiclass Support Vector Machine (SVM) method. SVM was considered to have a good reputation in the classification. This research tests the effect of summary as selection features into documents classification. The summaries reduce text into 50%. A result obtained that the summaries did not affect value accuracy of classification of documents that use SVM. But, summaries improve the accuracy of Simple Logistic Classifier. The classification testing shows that the accuracy of Naïve Bayes Multinomial (NBM) better than SVM
