Abstract

This paper introduces a set of guidelines for annotating time expressions with a canonicalized representation of the times they refer to. Applications that can benefit from such an annotated corpus include information extraction (e.g., normalizing temporal references for database entry), question answering (answering "when" questions), summarization (temporally ordering information), machine translation (translating and normalizing temporal references), and information visualization (viewing event chronologies).
