Figure 4: Results of exponential smoothing algorithm for all article types (Forecast ± 95% C.I). Number of articles will increase from 14884 in 2015 to 19195 articles in 2036. Alpha parameter is 0.9 and beta parameter is zero, showing the forecast is based more on the recent data and trends. Gama parameter is zero, indicating the data and forecast are not influenced by the seasonal changes. Mean absolute scaled error (MASE) is 0.70 and symmetric mean absolute percentage error (SMAPE) is 0.03, indicating a high level of forecast accuracy
