Automatic Situation Report Generation
We are pleased to announce the LT4CPR 2026 Shared Task on Automatic Situation
Report Generation, hosted as part of the LT4CPR Workshop at AACL-IJCNLP 2026.
The shared task focuses on generating structured situation reports from
crisis-related social media messages. Participants will develop systems that
identify and summarize important information about an unfolding crisis,
including reported impacts, affected populations, infrastructure damage,
response activities, resource needs, and other information relevant to
situational awareness.
The task is intended to support research at the intersection of natural
language processing, crisis informatics, summarization, information extraction,
multilingual language technology, and humanitarian response.
Task Overview
- Input
-
A collection of crisis-related social media messages, together with relevant
metadata and task documentation.
- Output
-
A structured and/or narrative situation report summarizing the key
information contained in the input messages.
Task Resources
The organizers plan to release:
- Training data
- Sample input, sample system output, and a sample gold-standard report
- Detailed input and output format documentation
- A situation-report template and machine-readable output schema
- Annotation and dataset documentation
- Baseline code and example outputs, where available
- Evaluation documentation, metrics, and evaluation scripts
- Submission-format validation tools
- Test data and system-submission instructions
- A submission platform for system outputs and shared-task papers
Participation tracks and additional task settings are currently being finalized
and will be announced separately.
System Description Papers
Participating teams will be invited to submit a system description paper
explaining their approach, experimental setup, use of external resources,
results, limitations, and relevant ethical considerations.
Researchers interested in participating are encouraged to register by
Sep 5th, 2026.
