Abstract
In recent years, positive practical use of big data is considered by many companies and various types of industries. In those considerations, since consumers' mindset (thinking and/or a sense of values, etc.) is much contained in social-media data, the expectation for practical use of this data is also growing. In this paper, we look down at the present condition related to social media usage, and describe the possibility of social-media data utilization. Especially, the possibility, merit, and subject of grasping "What" and "Why" about consumers' trend by fusion analysis with other business data is described. Moreover, a trend analysis and a solution are introduced as an example of these use-cases.
