TIDES: 2003 Standard for the Annotation of Temporal Expressions
Abstract
During the 1990s, the field of computational linguistics achieved several practical advances through the construction of annotated corpora for developing and testing various technologies. This document describes a set of guidelines for annotating temporal expressions with a normalized representation of the times they denote. This work has been carried out in support of a number of research activities under the Defense Advanced Research Projects Agency (DARPA) Translingual Information Detection, Extraction, and Summarization (TIDES) research program and the Automatic Content Extraction (ACE) program. Research which can directly benefit from this document includes question answering (e.g., answering "when" questions or time-dependent questions), relation and event characterization and tracking, visualization of events on timelines, and production of biographical summaries. Other research related to information extraction can also benefit.
