Kakao Arena 2nd Competition: Brunch Data Analysis Reveals Recency and Subscriptions Drive Consumption

The Kakao Arena 2nd competition focuses on predicting Brunch article consumption, and data exploration and visualization results were released for participants. The analysis reveals that 'recency' is a critical factor in Brunch article consumption, with consumption on the day of publication being approximately twice as high as after one day, and the proportion of consumption within 7 days reaching approximately 58%. Additionally, the phenomenon of consumption surging several days after publication was analyzed to be primarily due to inflow from other distribution channels such as SNS. For the 'Weekly Magazine', there is a distinct periodicity based on the day of the week for publication, and when new articles are published, consumption of previous issues also increases. In the analysis of reader subscription data, 98% of all readers have subscribed authors, with an average of 9 authors subscribed. The proportion of total consumption data consumed by readers who have subscribed authors is 93%, and among that, the proportion of consumption of articles by subscribed authors is 35%, indicating that approximately 1/3 of the articles read by readers are content from subscribed authors.
