Smartphoneベース旅行者参加型センシングシステムにより収集した主観的観光情報のGHSOMによる分類と知識獲得-広島県観光マップの開発と観光情報の分析-

摘要

Located in Hiroshima, which is remote from big cities, it is well-known widely as a sightseeingspot of World Heritage Site. A mobile phone participatory sensing system in tourist subjective datacollection has been developed with Android smartphone. In order to analyze the subjective data, we usethe Growing Hierarchical SOM and our proposed variant methods. One is the control method of thegrowing degree by pruning off the redundant branch of hierarchy. The other is the local reclassificationbased on human intuitive in the Android interface tool. In this paper, we classified the subjective data byinteractive GHSOM and extracted knowledge related to Hiroshima sight seeing spot by C4.5.
