Abstract(in English) | Recently most people utilize smart-phone and post some information into social media such as Twitter and Facebook. Following this situation, much information relating to damage can be published by affected people in social medias. In those information, there could be many photos which represent actual indoor-damage and outdoor-damage. In order to retrieve damage information from photos posted in social media, we tried to utilize “Machine Classification” technology based on actual posted twitter data at 2016 Kumamoto Earthquake. First, we gathered twitter data tweeted in Kumamoto area with photos and geolocation, which amount was 5,853. Then, we retrieve 5,684 photos from those tweets, and we classified them into “indoor damage”, “building damage (outdoor damage)” and “road damage (outdoor damage)” as teacher data. The machine learned those teacher data in deep-learning method, and the machine tried to classify random-sampled photos into “indoor-damage” or “outdoor-damage”. We verified those result, and we found that over 80% photos can be classified adequately by machine classification without specified customization. |
