As for E-T pairs, we build a set of rules based on the temporal senses of some prepositions (Litkowski and Hargraves, 2006;Litkowski, 2014).
3 we assign a label whenever a temporal preposition establishes a dependency path between an event (E) and a timex (T), in which T acts as the temporal modifier of E. For example, if T is introduced by a temporal prepositions expressing a STARTTIME sense such as from or since, the relation is labelled as BEGUN BY.
