This paper presents a demonstration of a tem- poral reasoning system that addresses three fundamental tasks related to temporal expres- sions in text: extraction, normalization to time intervals and comparison. Our system makes use of an existing state-of-the-art temporal ex- traction system, on top of which we add sev- eral important novel contributions. In addi- tion, we demonstrate that our system can per- form temporal reasoning by comparing nor- malized temporal expressions with respect to several temporal relations. Experimental study shows that the system achieves excellent performance on all the tasks we address.
