Overall flow of this study. The inverted trapezoidal frame shows manual processing or human judgment. The rectangular frame shows automatic processing by a hand-made program written in Python. The filled arrows indicate the flow in the first run of semi-authorized learning. Arrows with fine diagonal lines indicate the flow in the second run of semi-authorized learning. Arrows with rough diagonal lines indicate the flow in the third and subsequent runs of semi-authorized learning. CST: Confirmed self-training, AL: Active learning.
