Outline of Final Research Achievements

The purpose of this research was to establish a systematic approach for analyzing how e-WoM (e-Word-of Mouth) may affect performances of products and services on the Internet. With focus on digital cameras and movies, an ambitious attempt was made to conduct a comparative analysis between the United States and Japan, which remains incomplete because of the difficulty to create a common dictionary for text mining across English and Japanese. The project was quite successful, however, in the study of smartphone applications in Japan, where new knowledge was created concerning popularity, stability, security risk, prediction of the number of downloads, competitive or complementary relationships and the like. The validity of the proposed approach was also demonstrated by applying it to problems surrounding big data analytics in several different areas.
