Automatic Compilation of Travel Information from Automatically Identified Travel Blog Entries

Abstract

In this paper, we propose a method for compiling travel information automatically. For the compilation, we focus on travel blog entries, which are defined as travel journals written by bloggers in diary form. We consider that travel blog entries are a useful information source for obtaining travel information, because many bloggers' travel experiences are written in this form. First, we identified travel blog entries in a blog database. Next, we extracted souvenir information and tourist spots information as travel information from them. Furthermore, we extracted hyperlinks from travel blog entries and constructed the collection of travel information links. We have confirmed the effectiveness of our method by experiment. For the identification of travel blog entries, we obtained scores of 38.1% for Recall and 86.7% for Precision. In the extraction of travel information from travel blog entries, we obtained 74.0% and 71.0% for Precisions at the top 100 extracted local products and tourist spots, respectively, and thereby confirming that travel blog entries are a useful source of travel information. In the construction of the collection of travel information links, we obtained high precision and recall.
