This paper investigates the impact of us- ing different temporal algebras for learn- ing temporal relations between events. Specifically, we compare three interval- based algebras: Allen (1983) algebra, Bruce (1972) algebra, and the algebra de- rived from the TempEval-07 campaign. These algebras encode different granular- ities of relations and have different infer- ential properties. They in turn behave dif- ferently when used to enforce global con- sistency constraints on the building of a temporal representation. Through various experiments on the TimeBank/AQUAINT corpus, we show that although the TempE- val relation set leads to the best classifica- tion accuracy performance, it is too vague to be used for enforcing consistency. By contrast, the other two relation sets are similarly ha...
