ALICE flowchart. ALICE scans each sentence four times in the Inner Search (IS) phase (1 ≤ n ≤ 4), and it checks each string before the left parenthesis up to 16 times in the Outer Extraction (OE) phase (1 ≤ m ≤ 16). The extracted inner-outer pair is evaluated with the five acceptance conditions in the Validity Judgment (VJ) phase.
