Parsing Time Normalizations

# Parsing Time Normalizations
# Based on Laparra et al., SemEval 2018
# Paper: https://aclanthology.org/S18-1011/
# Dataset: https://github.com/bethard/anafora-annotations
#
# This task asks annotators to identify time expressions in text and
# normalize them to ISO 8601 format. Annotators first highlight time
# expression spans, then provide the normalized ISO representation.
#
# Span Labels:
# - Time Expression: Any expression referring to a point or period in time
#
# Normalization: ISO 8601 format (e.g., 2018-03-15, 2018-W12, PT2H30M)

annotation_instructions: |
  You will be shown a text passage along with the document date for reference.
  Your task is to:
  1. Highlight all time expressions in the text (dates, times, durations, frequencies).
  2. Provide the ISO 8601 normalized form for each time expression.
  Use the document date to resolve relative expressions like "yesterday" or "last week".
