Abstract
The TACTE system proposed in this paper focuses
on one problem in natural language processing, namely
recognizing textual entailment involving temporal expressions. The system consists of two components: one
for temporal expression extraction and anchoring, and
the other one for recognizing textual entailment based
on events. The entailment rules are constructed using
a small set of temporal expression relations and lexical
resources. Several experiments are conducted, and various aspects of the system performance are illustrated.
The evaluation on different data sets shows the great
improvement of our TACTE system in comparison with
the baseline. As a system potentially to be integrated
into a larger framework, TACTE is shown to be very
promising as a specialized module on entailment cases
where temporal expression information is available.
