Real-time analysis application for identifying bursty local areas related to emergency topics.

Sakai T, Tamura K - Springerplus (2015)

Bottom Line: Many researchers have been tackling the development of new data mining techniques for georeferenced documents to identify and analyze emergency topics, such as natural disasters, weather, diseases, and other incidents.In particular, the utilization of geotagged tweets to identify and analyze natural disasters has received much attention from administrative agencies recently because some case studies have achieved compelling results.Moreover, we have implemented two types of application interface: a Web application interface and an android application interface.

ABSTRACT
Since social media started getting more attention from users on the Internet, social media has been one of the most important information source in the world. Especially, with the increasing popularity of social media, data posted on social media sites are rapidly becoming collective intelligence, which is a term used to refer to new media that is displacing traditional media. In this paper, we focus on geotagged tweets on the Twitter site. These geotagged tweets are referred to as georeferenced documents because they include not only a short text message, but also the documents' posting time and location. Many researchers have been tackling the development of new data mining techniques for georeferenced documents to identify and analyze emergency topics, such as natural disasters, weather, diseases, and other incidents. In particular, the utilization of geotagged tweets to identify and analyze natural disasters has received much attention from administrative agencies recently because some case studies have achieved compelling results. In this paper, we propose a novel real-time analysis application for identifying bursty local areas related to emergency topics. The aim of our new application is to provide new platforms that can identify and analyze the localities of emergency topics. The proposed application is composed of three core computational intelligence techniques: the Naive Bayes classifier technique, the spatiotemporal clustering technique, and the burst detection technique. Moreover, we have implemented two types of application interface: a Web application interface and an android application interface. To evaluate the proposed application, we have implemented a real-time weather observation system embedded the proposed application. we used actual crawling geotagged tweets posted on the Twitter site. The weather observation system successfully detected bursty local areas related to observed emergency weather topics.

Fig11: Extracted bursty areas in western Japan on July 3, 2014.

Mentions: Figure 10 shows that alteration of extracted bursty areas associated with topic “snow” from moment to moment on December 20, 2013. The western part of Japan had first snow in the morning. We observed the system in real time. As the expanding snowfall areas, the number of extracted bursty areas increased. We could analyzed and identify which areas had heavy snowfall and what were tweeting. Figure 11 shows that alteration of extracted bursty areas associated with topic “rain” from moment to moment on July 3, 2014. The western part of Japan had heavy storm in the morning; especially, in the northern part of Kyushu, which is located at the west end of Japan, torrential rainfall occurred. Figure 11 shows that many bursty areas were extracted in the northern part of Kyushu at each time.Figure 10
