We present an approach for learning context-dependent semantic parsers to identify and interpret time expressions. We use a Combinatory Categorial Gram- mar to construct compositional meaning representations, while considering contex- tual cues, such as the document creation time and the tense of the governing verb, to compute the final time values. Exper- iments on benchmark datasets show that our approach outperforms previous state- of-the-art systems, with error reductions of 13% to 21% in end-to-end performance.
