Visualizing Web Application of Archiving Views of Railway StationsʟExperiences for Strollers
Harada Makiko†1,†2,a)Komatsu Yoshiaki†3,b)

Watanave Hidenori†1,c)

Abstract: Our study in this paper aims to show railway stationsʟ experiences for strollers from the pointof usersʟ view. To approach this purpose, we propose a visualizing web application to archive the viewsof railway stations experiments between stroller users and other people. We create a system to collect theviews from Twitter and our own contribution system. We apply language analysis to the views and extract
usersʟ sentiment and key phrases. In addition, we visualize these views to overview with sentiment and key
phrases simultaneously. We consider that our work will give a better understanding of various inconveniences
for stroller users, and propose guidelines of what kind of behavior and understanding are required for eachother.
