Abstract:This study investigates how to represent set-denoting temporal expressions with ISO-TimeML, a state-of-the-art framework for representing time expressions. Specifically, we will show its limitations, caused by characteristics of TIMEX3; i) the freq attribute can not represent both the frequency of time points and the time granularity at the same time. ii) set expressions structurally containing another set expressions can not be annotated in the current framework. iii) value attribute can not contain values of… Show more
