Construction of a System for Providing Travel Information along Hiroden Streetcar Lines

We propose a method for collecting Hiroshima Electric Railway (Hiroden) blog entries in a blog database. Hiroden blog entries are defined as travel journals that provide regional information at Hiroden streetcar stations. The task of collecting Hiroden blog entries is divided into two steps: (1) collection of blog entries, and (2) identification of Hiroden blog entries. To investigate the effectiveness of our method, we conducted some experiments. From the experimental results, we obtained precision of 82.4%, recall of 64.5%, and F-measure of 72.4% in automatic identification of Hiroden blog entries. Finally, we have constructed a system for providing travel information along Hiroden streetcar lines.
