The purpose of this study is to analyze the consumption feeling of Korean professional baseball spectators through semantic network analysis, one of the big data analysis techniques. To do this, I collected Korean professional baseball texts from Naver and Daum blogs, which ranked 1st and 2nd in the ranking of visitors to the website. The collected texts were extracted through the refinement process and the top 100 words were extracted. Then, through the semantic network analysis, the consumption feeling of Korean professional baseball spectators was confirmed. As a result, there were three types of consumer sentiment among Korean professional baseball spectators. The first of it was fun given by professional baseball itself. Professional baseball has a lot of fun. From the fun of uncertainty that can not be predicted until the end of the 9th out, there are a variety of stories about players and teams both inside and outside the stadium throughout the season. Therefore, in order to continue the popularity of professional baseball, it is necessary to constantly discover and actively promote the fun given by professional baseball itself. The second is a playful element given by the space called the baseball field. The supportive culture in which the regional colors are combined with the operating system based on the local area was the driving force for the crowd to the stadium. Therefore, it is necessary to closely examine and actively utilize the meaningful factors in the stadium. The third is the enjoyment and expression of mainstream culture. It was a driver who was able to show off the professional baseball which is perceived as mainstream culture and which seat and whom he is consuming with itself, to find baseball field again.
