SUMMARY:Context-dependent Semantic Parsing for Time Expressions - Jesse Do

DESCRIPTION:We present an approach for learning context-dependent semantic
  parsers to identify and interpret time expressions. We use a Combinatory 
 Categorial Grammar to construct compositional meaning representations\, wh
 ile considering contextual cues\, such as the document creation time and t
 he tense of the governing verb\, to compute the final time values. Experim
 ents on benchmark datasets show that our approach outperforms previous sta
 te-of-the-art systems\, with error reductions of 13% to 21% in end-to-end 
 performance.
