Factor Analysis for Game Software Using Structural Equation Modeling with Hierarchical Latent Dirichlet Allocation in User’s Review Comments

Rikuto Kunimoto, Hiroshi Kobayashi, and Ryosuke Saga
Abstract—While the market investigation is important in game software development, there is a problem that there is no effective way to pursue the factor of user's software evaluation. In this research, we paid attentions to corpus (electric existence of documents) considered that the factor relationships about the user's evaluation were expressed potentially as their opinions. As the way to achieve this idea, we tried to extract useful knowledge by using SEM and topic model for visual and quantitative analysis process. As the related work, there are several researches about Game software market using text mining methods (LSI, or LDA). However, they have the problem concerning to objectivity or explanations because the relationships between topics are not defined based on technical algorithms and expressed only as the frequency of the words that constructs the topics. Experimental results showed that our proposal process can extract effectively the topics that users pay attentions when they evaluate the game software and we can interpret it.

Index Terms—Causal analysis, factor expression, game software, structural equation modeling, topic model, hierarchical latent dirichlet allocation.
