Development of the Combination Analysis Method of Visited Places of Foreign Visitors to Japan by GPS Log Data

Abstract

The purpose of this paper was to develop the combination analysis method of visited places by foreign visitors to Japan. For identification of combination patterns, the topic model was applied using GPS tracking data of smartphone applications of foreign tourists. This model was supposed as a method of identifying segments of destinations and visitors simultaneously. The number of unique users collected in 2015 was 55,199. We had data cleaning for bias caused due to sampling ratio and the noise of GPS positioning data. In the estimation, it was found appropriate to set the number of topics as six. The visited rates and visitors’ topic distribution of each zone were also estimated by this model.
