AACL Commitment Guide: Tips and Templates for Writing Your Response to Metareview

Background: ACL Rolling Review and the Commitment Mechanism

For researchers submitting to *CL conferences (such as ACL, EMNLP, AACL) for the first time, the ARR (ACL Rolling Review) review and Commitment process can be quite confusing. Recently, a researcher sought help in the community: their paper received an OA (Overall Assessment) of 3.17 and a Meta-Review score of 3. When committing to AACL, the system required them to fill in a "Response to Metareview" field with a maximum of 2000 characters, and they had no idea where to start.

This is a very common question for newcomers. This article systematically covers the purpose of this component, the writing logic behind it, and practical tips to help you maximize persuasiveness within the limited character space.

What Is the ARR Commitment Process?

ARR uses a "rolling review" model: papers are first submitted to ARR to receive reviewer comments and a Meta-Review, and authors can then choose to "commit" the paper (with its review results) to a specific conference (such as AACL). The conference's SAC (Senior Area Chair) and program committee then make the final acceptance decision based on the ARR review results combined with the conference's acceptance criteria.

ACL Rolling Review officially launched in 2021 and represents one of the most significant review reforms in computational linguistics. Previously, each *CL conference organized reviews independently, leading to reviewer overload and inconsistent review quality. ARR decouples the review process from conference decisions: papers can be submitted to the ARR platform (based on the OpenReview system) before monthly deadlines, go through an approximately two-month review cycle to receive reviewer feedback, and then authors can choose to "commit" the review results to any conference that accepts ARR reviews. This model allows authors who receive unfavorable reviews to revise and resubmit to the next ARR cycle, rather than being forced to wait for the next conference submission deadline.

Precisely because the final decision-makers may not be the original reviewers, the "Response to Metareview" becomes a critical window for authors to communicate directly with the conference decision-making layer. In *CL conferences, the program committee typically adopts a three-tier structure: Reviewers write detailed review comments, Area Chairs (ACs, i.e., Meta-Reviewers) synthesize multiple reviewers' opinions into a Meta-Review, and Senior Area Chairs (SACs) rank and make final recommendations for all papers within a topic area. Under the ARR Commitment mechanism, what SACs see is a completed review package—including the original reviews, Meta-Review, the author's Rebuttal, and the Response to Metareview. Since SACs typically do not re-read the full text of every paper in depth, they rely heavily on the Meta-Review and the author's Response to make judgments in borderline cases.

What Should the Response to Metareview Actually Contain?

The essence of this field is to allow authors to respond to the core issues summarized by the Meta-Reviewer and explain why the paper deserves to be accepted at the conference. It differs from the Rebuttal stage where you address each reviewer's comments point by point—it's a more condensed "closing statement."

It's important to understand that in the ARR process, the Rebuttal occurs during the review stage: after receiving reviewer comments, authors have a window (usually one week) to respond to each reviewer's points, after which reviewers and ACs may update their scores. The Response to Metareview occurs during the Commitment stage—it's what authors fill in when they decide to submit their paper to a specific conference. The audiences are different—the Rebuttal primarily addresses the original reviewers and AC, while the Response to Metareview addresses the conference's SAC and program committee chairs. This means the Response needs to be more self-contained and more concise, as readers may not have read every detail of the Rebuttal.

Core Objectives

• Address the main concerns raised in the Meta-Review: The Meta-Review typically summarizes the consensus opinions of reviewers, and you need to respond to these key points.
• Highlight the paper's contributions and fit: Explain why your work meets the target conference's scope and quality standards.
• Describe completed or planned revisions: If you promised revisions during the Rebuttal, briefly explain how you've followed through.

A Realistic Assessment of the Scores

The researcher's OA of 3.17 and Meta score of 3 fall in the "borderline-to-slightly-positive" range. ARR's Overall Assessment uses a 1-5 scale, where 1 means strong reject and 5 means strong accept. A score of 3 typically corresponds to "borderline," meaning the paper has some contribution but also notable weaknesses. A score of 3.17 means the average of three reviewers' scores is slightly above borderline (e.g., possibly a combination of 3, 3, and 3.5). Based on historical acceptance data from *CL conferences, papers with OA in the 3.0-3.5 range have highly variable acceptance rates, heavily dependent on the specific conference's acceptance rate (typically 20%-25%) and the competitiveness of the topic area.

At most *CL conferences, a Meta-Review score of 3 (typically corresponding to borderline or leaning accept) means the paper has a chance of being accepted but is far from a sure thing. In such cases, the quality of this Response may directly influence the SAC's judgment, making it worth taking seriously.

Regarding the choice of target conference, AACL (Asia-Pacific Chapter of the ACL) is ACL's chapter conference in the Asia-Pacific region, usually held jointly with IJCNLP. Compared to the main ACL and EMNLP conferences, AACL is smaller in scale with fewer accepted papers, but its academic influence has been steadily growing in recent years. AACL particularly focuses on NLP research related to Asia-Pacific languages, multilingual processing, and low-resource language technology, while also accepting high-quality work in general NLP. Understanding the target conference's focus areas helps you better articulate your paper's fit in the Response.

Recommended Writing Structure (2000-Character Framework)

2000 characters (approximately 300-350 English words) is very limited, so you need to be highly concise. Here's a reusable framework:

Opening: Acknowledgment and Positioning (1-2 sentences)

Briefly thank the Meta-Reviewer and reviewers, and use one sentence to highlight the paper's core contribution. For example:

"We thank the reviewers and the meta-reviewer for their constructive feedback. Our work presents [one-sentence summary of core contribution]."

Body: Point-by-Point Response to Key Concerns

Extract 2-3 of the most critical points from the Meta-Review and address each one concisely. For each point, you can use a "concern—response—evidence" structure:

• State the concern mentioned in the Meta-Review
• Explain your response (clarified / added experiments / corrected phrasing)
• Cite specific revision locations or supporting data

Closing: Fit and Value Summary (1-2 sentences)

Reaffirm the paper's value to the community and why it's suitable for publication at AACL.

Practical Writing Tips

Focus on Key Issues Rather Than Covering Everything

2000 characters is not enough to address every detail. Prioritize the key issues emphasized in the Meta-Review that affect the acceptance decision, rather than getting bogged down in minor flaws. What the SAC cares about is "whether the paper's core weaknesses have been reasonably addressed."

Echo Your Rebuttal Content

If you already provided detailed responses during the ARR Rebuttal stage, your Response to Metareview should be consistent with those and distill their essence. You can explicitly state something like "As we noted in our rebuttal and as acknowledged by the reviewers..." to demonstrate continuity in the review process. This is especially important because SACs can see the complete review history—if the Response contradicts the Rebuttal, it will seriously damage credibility.

Replace Defensiveness with Facts and Commitments

Avoid emotional or overly defensive tones. Verifiable statements like "we have added experiment X" or "we have corrected Y in the camera-ready version" are far more persuasive than simply claiming "the reviewer misunderstood." Note that in *CL conferences, "camera-ready" refers to the final version submitted after a paper is formally accepted. Revisions promised for the camera-ready are considered formal commitments to the academic community, and conference organizers have the right to verify whether these revisions have been implemented.

Maintain a Professional and Restrained Tone

Even if you believe some review comments are unfair, express this in a professional, constructive manner. Decision-makers prefer authors who respond to issues calmly. Academic review is fundamentally a scholarly dialogue among peers—demonstrating respect for critical feedback and showing thoughtful responses is itself a sign of academic maturity.

Response to Metareview Example Template

We thank the meta-reviewer for the summary. The main concern raised was the limited comparison with recent baselines. In our rebuttal, we added experiments against [Baseline A/B], showing consistent improvements (Table X), which the reviewers acknowledged. Regarding the clarity of Section 3, we have revised the notation and added an illustrative example. We believe our contribution—[one-sentence restatement]—is well-aligned with AACL's scope and offers value to the community. All promised revisions will be incorporated in the camera-ready version.

This template is approximately 500-600 characters, leaving ample room for authors to expand based on their paper's specific circumstances. When writing in practice, it's recommended to first draft a complete version in a document, then gradually trim it to under 2000 characters, ensuring every sentence carries key information.

Conclusion

Although the Response to Metareview is just one small step in the Commitment process, for papers in the borderline score range, it can be an important variable that influences the final acceptance decision. The core principles are simple: focus on key issues, respond with facts, and maintain professional restraint. Treat it as your last opportunity for direct dialogue with the conference decision-makers—taking it seriously often yields positive returns.

From a broader perspective, ARR's Commitment mechanism gives authors greater agency—you can choose to commit to the most suitable conference at the most favorable time based on your review results. Understanding and leveraging every component of this mechanism, including the Response to Metareview, is an essential skill for success in today's NLP academic publishing ecosystem.

Best wishes to this first-time submitter for a successful acceptance.
