The rapid growth of information technology and mobile service platforms, i.e., internet, google, and facebook, etc. has led the abundance of data. Due to this environment, the world is now facing a revolution in the process that data is searched, collected, stored, and shared. Abundance of data gives us several opportunities to knowledge discovery and data mining techniques. In recent years, data mining methods as a solution to discovery and extraction of available knowledge in database has been more popular in many fields such as movie recommendation of e-commerce service. However, most of classification approaches for predicting movie popularity have used only several types of information of the movie such as actor, director, rating score, language and countries etc.
In this study, we propose a classification-based support vector machine (SVM) model for predicting the movie popularity based on movie’s genre data and social network data. Social network analysis (SNA) is used for improving the classification accuracy. This study builds the movies’ network (one mode network) based on initial data which is a two mode network as user-to-movie network. For the proposed method we computed degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality as centrality measures in movie’s network. Those four centrality values and movies’ genre data were used to classify the movie popularity in this study. The logistic regression, neural network, naive Bayes classifier, and decision tree as benchmarking models for movie popularity classification were also used for comparison with the performance of our proposed model. To assess the classifier’s performance accuracy this study used MovieLens data as an open database. Our empirical results indicate that our proposed model has about 10% higher accuracy than other classification models. The implications of our results show that our proposed model could be used for improving movie popularity classification.
