概要 Traffic phenomena including accidents occur daily on the Japanese road network. Surveillance cameras and traffic counters are used to monitor them; however, since it is fixed-point monitoring, there is a limit to the extent of monitoring. Thus, method has been proposed for analyzing microblogs, a kind of SNS (social networking service), to complement acquisition of information concerning traffic phenomena. However, as preset keywords are used to make searches, the number of acquirable TWEETS fluctuates. Therefore, this research proposes a method for selecting useful keywords for acquiring information on traffic phenomena using the characteristics of the concerned keywords to burst when a traffic phenomenon occurs, and evaluates its validity.
