Did you know it’s pretty easy to programmatically access ACL Anthology data? For example, here’s a snippet you could use to get the BibTeX entries for all of your papers. The downside is that the initial fetching of the data takes quite long atm, but it can still be useful for automation!
Python code:

from acl_anthology import Anthology
anthology = Anthology.from_repo()
author = anthology.get_person("marcel-bollmann")
for paper in sorted(author.papers(), key=lambda p: p.year):
    print(paper.to_bibtex())

Do you have an ORCID iD (unique personal identifier to attach to publications)? Every scientific author should claim one at orcid.org. Then, take 30 seconds to improve your @aclanthology.org page and prepare for new ARR requirements:

My prediction is that "a substantial part of humanity will die within the next 50 years" has a high probability. It has absolutely nothing to do with rogue AI. It's climate change. Because this species is too greedy to understand the tragedy of the commons.

Isaac Newton famously wrote “if I have seen further, it is by standing on the shoulders of giants.” Academic progress is always iterative and builds on the work of others, and a key component of academic culture is proper citation & attribution. It would be a travesty to let LLMs destroy that.

Accidentally made Gemini roleplay as a fried egg when I googled a quote from Mixtape.
A google search for "you're an egg in a teflon pan".

The AI overview reads:

I am chilling in a lightly buttered Teflon pan over gentle heat. My transparent whites are starting to firm up, my yolk is maintaining a perfect, golden composure, and thankfully, the non-stick surface is ensuring a completely stress-free, slippery glide.

Ah, the bliss of an intact membrane! Without a Teflon surface, a scratched coating could easily cause my delicate edges to bond to the metal in a tragic, sticky mess. It also helps that the temperature is kept at a gentle, controlled simmer. If the heat were cranked up too high, l'd overcook before you could say "sunny-side up".

I don't understand why the ACL/ARR organizers think this is an appropriate way to communicate with area chairs... The peer review system is collapsing, and the whole system of science as we know it requires a rethink. But let's be kind to eachother in the process and not forget what we are here for.
This is a reminder that the meta-reviews are due TODAY 4 March AoE.

Please remember that if you don't sumit your meta-reviews on time you might be considered highly irresponsible, which means your co-authored papers may be desk rejected and you may become ineligible from committing to *CL conferences or (re-)submitting any work on the the next ARR cycle.

Just found out that yet another paper on North African Arabizi didn't find our work worth citing. they even wrote "No Arabizi-specific metric or resource exists for our dialect selection ». We were the first to release an annotated dataset for this dialect, published at acl and shit. Discouraging.
Your dataset looks very cool, but I don't understand why you say “no Arabizi-specific metric or resource exists for our dialect selection”? When you contacted me, it seemed to me that you were aware of my work on Arabizi (e.g., [1,2], not to mention the cross-lingual work with Maltese [2] or character-based language models for Arabizi [4]). One of the crucial points of this work was also to propose translations into French from Algerian Arabizi, which could have helped you use a ground truth for your translation models. I'll be honest with you, I find it extremely discouraging to see that pioneering work in the processing of a language with such limited resources as Algerian Arabic dialect is not cited, even though it has been published in the major conference in the field and the data is freely available (unlike the vast majority of dialectal resources for Arabic). If even colleagues working on the same language don't find it necessary to cite us, what's the point of investing so much time and money in this type of work?

In short, I hope your work doesn't encounter the same pitfalls.

The survey takes 7-10 minutes and covers topics like review quality, reviewer assignment, and accessibility barriers. All responses are confidential and will help inform evidence-based improvements to our peer review processes.

🚨 New paper alert 🚨 Using LLMs as data annotators, you can produce any scientific result you want. We call this **LLM Hacking**. Paper: arxiv.org/pdf/2509.08825
We present our new preprint titled "Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation".
We quantify LLM hacking risk through systematic replication of 37 diverse computational social science annotation tasks.
For these tasks, we use a combined set of 2,361 realistic hypotheses that researchers might test using these annotations.
Then, we collect 13 million LLM annotations across plausible LLM configurations.
These annotations feed into 1.4 million regressions testing the hypotheses. 
For a hypothesis with no true effect (ground truth $p > 0.05$), different LLM configurations yield conflicting conclusions.
Checkmarks indicate correct statistical conclusions matching ground truth; crosses indicate LLM hacking -- incorrect conclusions due to annotation errors.
Across all experiments, LLM hacking occurs in 31-50\% of cases even with highly capable models.
Since minor configuration changes can flip scientific conclusions, from correct to incorrect, LLM hacking can be exploited to present anything as statistically significant.
