Twitter event photo detection using both geotagged tweets and non-geotagged photo tweets

Abstract

In this paper, we propose a system to detect event photos using geotagged tweets and non-geotagged photo tweets. In our previous work, only “geotagged photo tweets” was used for event photo detection the ratio of which to the total tweets was very limited. In the proposed system, we use geotagged tweets without photos for event detection, and non-geotagged photo tweets for event photo detection in addition to geotagged photo tweets. As results, we have detected about ten times of the photo events with higher accuracy compared to the previous work.
