| Abstract(in English) | Using travel photos with latitude and longitude information in Flickr and image recognition technology, we conducted a study to automatically generate image explanations that are useful for tourist information. In this paper, we report the results of the Shimanami Kaido, where many tourist cyclists from Japan and abroad gather. First, using the information obtained from the Google Cloud Vision API as a clue, the photos are automatically classified into five categories: “see”, “eat”, “buy”, “experience”, and “stay”. Next, we detect tourist spots using DBSCAN. Based on the classification information of the images assigned to the tourist spots, a template for the explanation was generated. Furthermore, the explanation of the image was automatically generated by combining the template and the image label for each classification result. From the evaluation experiment, it was found that the explanation of the tourist spot was adequate and fluent, and the explanation was easy to convey to people. |
