Fig. 4. (Color online) In the 17th-19th presidential elections, changes in the average Google Trends value, three months, two months, one month, two weeks, and one week before the election day. In the left (17th), middle (18th), and right (19th) panels, it can be seen that the winner of each presidential election had the largest average Google Trends value during the entire election period. In addition, in the 19th presidential election, Jun-pyo Hong had an average Google trend value slightly less than Cheol-soo Ahn at first, but in the final actual vote rate Hong surpassed Ahn's (21.41%) with a vote of 24.03%.
