Abstract

Mobile phone based Participatory Sensing (MPPS) systems involve a community of users
sending personal information and participating in autonomous sensing through their mobile phones. The
tourist subjective data collection system with Android smartphone has been developed. The application
can collect subjective data such as pictures with GPS, geographic location name, the evaluation and
comments in real 500 sightseeing spots. In this paper, we analyze 500 subjective data by using interactive
Growing Hierarchical Self Organizing Map (interactive GHSOM). The control method of the growing
degree by pruning off the redundant branch of hierarchy in GHSOM has been proposed and the criteria
were designed by the adjustment of parameter settings according to the squared error and the size of map.
Moreover, the classification result by GHSOM were compared with knowledge extracted by C4.5.
