Development of Potential-of-Interest Maps Using Tourists'Photo-Shooting Location Data and Their Application to Tourist Information Service

利用在线照片分享网站上的游客照片数据，我们开发了潜在兴趣地图，将许多游客出于某种原因感兴趣的地点可视化。我们还开发了一个基于潜在兴趣地图的移动旅游信息工具，并通过用户测试检验了它的实用性。此外，我们还开发了几个过滤器来区分与旅游相关的照片，从而提高了地图的质量。潜在地图在改善旅游目的地的空间设计和旅游信息时也很有用。

Making use of tourists’ photo data uploaded at online photo-sharing sites, we developed potential-of-interest maps, which visualize the locations where a number of tourists has got interested for some reasons. We also developed a mobile tourist information tool based on potential-of-interest maps and examined its usefulness by a user test. In addition, we developed several filters which distinguish tourism-related photos from others, with which we improved the maps’ quality. Potential-of-maps are useful also for tourist destinations when improving spatial designs and tourist information.
