Although some steps can be run in parallel, the two modules interact, based on the assumption that the notion of causality is tightly connected with the temporal dimension and that information from one module can be used to improve or check the consistency of the other.
(i) TLINK labels for event-event (E-E) pairs, resulting from the rule-based sieve + temporal reasoner modules, are used as features for the CLINK classifier; and (ii) CLINK labels (i.e.
