... the effectiveness of our method by experiment. For the identification of travel blogs, we obtained scores of 38.1% for Recall and 86.7% for Precision. In the extraction of travel information ... travel information for all tourist spots and to keep them up to date manually. Therefore we have studied the automatic compilation of travel information. For the compilation, we f...
