Capturing public insights related to transit systems in social media has gained huge popularity presently. The regional transportation agencies use social media as a tool to provide information to the public and seek their inputs and ideas for meaningful decision making in transportation activities. This exploratory study attempts to gauge the impact of social media use in transportation planning that in turn would help transportation administration in identifying the day-to-day challenges faced by the customers and to suggest a suitable solution. This paper presents the effect of pre-processing techniques on transit opinion analysis to improve the performance. Performance of different pre-processing methods namely stop word removal, stemming, lemmatization, negation handling and URL removal using feature representation models namely TF-IDF with unigram, TF-IDF with bigram on three feature selection techniques including information gain, standard deviation and chi-square on social media transit rider’s opinion is carried out. The experimental results are evaluated using four different classifiers such as Support vector machine, Naïve Bayes, Decision Tree, K-Nearest Neighborhood in terms of accuracy, precision, recall, and f-measure. On analyzing the social media related transit opinion data, it is observed that pre-processing with bigram technique performs better than the other approaches specifically with Support Vector Machine and Naïve Bayes.

Credit scoring is a model commonly used in the decision-making process to refuse or accept loan requests. The credit score model depends on the type of loan or credit and is complemented by various credit factors. At present, there is no accurate model for determining which creditors are eligible for loans. Therefore, an accurate and automatic model is needed to make it easier for banks to determine appropriate creditors. To address the problem, we propose a new approach using the combination of a machine learning algorithm (Naïve Bayes), Information Gain (IG), and discretization in classifying creditors. This research work employed an experimental method using the Weka application. Australian Credit Approval data was used as a dataset, which contains 690 instances of data. In this study, Information Gain is employed as a feature selection to select relevant features so that the Naïve Bayes algorithm can work optimally. The confusion matrix is used as an evaluator and 10-fold cross-validation as a validator. Based on experimental results, our proposed method could improve the classification performance, which reached the highest performance in average accuracy, precision, recall, and f-measure with the value of 86.29%, 86.33%, 86.29%, 86.30%, and 91.52%, respectively. Besides, the proposed method also obtains 91.52% of the ROC area. It indicates that our proposed method can be classified as an excellent classification.

The internet especially social media has been a major platform where people interact with each other. We are able to interact with each other regardless of time and place because of the advancement of technology. Unfortunately, not all of the interaction that goes on are good or positive. One of the negative interaction that can happen online is cyberbullying which has rapidly increase throughout the years, whether it be through social media, emails or texting. Therefore, it is important to prevent cyberbullying from occurring which is why this research is done. Detection the presence of cyberbullying is one if the main issue in avoiding it from happening. Cyberbullying detection can be challenging because the many languages used in the world, most of the time slangs and informal languages are used and special characters like emoji are also used during online conversation. The aim of this research is to detect the presence of text cyberbullying from online post. Two term weighting schemes and two classification algorithms are compared in this research. The weighting schemes used namely Entropy and Term Frequency -  Inverse Document Frequency (TF-IDF) for feature selection and Naïve Bayes algorithm is used and compared with Support Vector Machine (SVM) algorithm. As a result, it shows that Naïve Bayes classifier yields a better accuracy when used with TF-IDF which is 97.60%. Hopefully this research is able give other researchers an insight, particularly to those who are interested in a similar area.

Cyber-bullying includes repeated acts with the aim of scaring, angering, or embarrassing those who are targeted Cyber-bullying is happening along with the rapid development of technology and social media in society. The media and users need to filter out bully comments because they can indirectly affect the mental psychology that reads them especially directly aimed at that person. By utilizing information mining, the system is expected to be able to classify information circulating in the community. One of the classification techniques that can be applied to text-based classification is Naïve Bayes. The algorithm is good at performing the classification process. In this research, the precision of the algorithm's has been carried out on 1000 comment datasets. The data is grouped manually first into the labels "bully" and "not bully" then the data is divided into training data and test data. To test the system's ability, the classified data is analyzed using the confusion matrix method. The results showed that the Naïve Bayes Algorithm got the level of precision at 87%. and the level of  area under the curve (AUC) at 88%. In terms of speed of completing the system, the Naïve Bayes Algorithm has a very good rate of speed with completion time of 0.033 seconds.
