Image Captioning Shared Task 2025

Paper Submission Guidelines

Paper Structure: Maximum 4 pages (excluding unlimited references).

1. Abstract

Brief summary of your paper in a few sentences.

2. Introduction

Task description and importance; mention language(s) covered; cite task overview paper
Your main system strategy
Key findings, ranking, challenges discovered; include code URL if available (Highly recommended)

3. Background

Summarize task setup: input/output types (with examples)
Dataset details: language, genre, size
Tracks participated in (if applicable)
Cite relevant related work showing your contribution's novelty

4. System Overview

Key algorithms and design decisions
Resources used beyond provided training data
How you addressed task challenges
Include equations/pseudocode for novel approaches
Provide concrete algorithm examples
For multiple systems, clearly distinguish each configuration

5. Experimental Setup

Data split usage (train/dev/test)
Preprocessing and hyperparameter details for replication
External tools/libraries (with versions and URLs)
Task evaluation metrics summary
Put detailed implementation in Appendix if space-limited

6. Results

Quantitative findings: Official metrics performance and ranking
Analysis: Ablations, comparisons, design decisions impact
Error analysis: System mistakes, confusion matrices, error types, make sure to provide some examples
Clearly mark which data split used for each analysis
Distinguish official vs. post-submission results

7. Conclusion

Summary of system, limitations, results, and future work directions.

8. Acknowledgments

Thank contributors, grants, anonymous reviewers.

9. Appendix

Low-level details for replication that aren't essential for understanding main concepts.

Formatting Requirements

Templates and Style

Must use: Official EMNLP 2025 (ACL) style templates (LaTeX or Word)
Download from: https://github.com/acl-org/ACLPUB
Follow: General "ACL" conference formatting guidelines
Do NOT: Modify style files or use templates from other conferences to avoid the paper rejection

Consequences

Non-conforming submissions (wrong paper size, margins, font size) will be rejected without review.

Key Principles

Focus on:

Replicability: Provide all necessary implementation details
Analysis: Emphasize results over rankings; include multiple runs and ablations
Clarity: Brief task outline (avoid duplicating task paper); use placeholder citations initially

Required elements:

Cite task overview paper
Follow EMNLP templates exactly
Use title format: <Team Name> at <Task Name>: <Your Contribution>
