In this paper, we aim to collect sightseeing information obtained from SNS and work on the task of predicting the posting location from a single tweet.We performed a trial of deepgeo, which has high accuracy in English datasets, in Japanese datasets, and evaluated its accuracy.We also propose a indicated deepgeo with that gives an indicator to words with place name attributes, and improved the accuracy of deepgeo.Through the experiments, the proposed method achieved about 1 point higher accuracy than deepgeo.
