Torching the Modern-Day Library of Alexandria β€œSomewhere at Google there is a database containing 25 million books and nobody is allowed to read them.”

I curated some readings for class on "data tensions" and the list felt worth sharing. Come on a tour of datasets, books, the web, and AI with me...

We'll start with this piece on the Google Books project: the hopes, dreams, disasters, and aftermath of building a public library on the internet.

We explore a fundamental question: How can we *automatically* learn which data is most valuable for training foundation models?

As DH grows, it’s increasingly important to publish conference papers, but there hasn’t been a clear venue for that.

So I’m thrilled to share this new home for DH proceedings, which will include CHR papers & more.

Thanks to @taylor-arnold.bsky.social for leading this effort!

A diagram illustrating pointwise scoring with a large language model (LLM). At the top is a text box containing instructions: 'You will see the text of a political advertisement about a candidate. Rate it on a scale ranging from 1 to 9, where 1 indicates a positive view of the candidate and 9 indicates a negative view of the candidate.' Below this is a green text box containing an example ad text: 'Joe Biden is going to eat your grandchildren for dinner.' An arrow points down from this text to an illustration of a computer with 'LLM' displayed on its monitor. Finally, an arrow points from the computer down to the number '9' in large teal text, representing the LLM's scoring output. This diagram demonstrates how an LLM directly assigns a numerical score to text based on given criteria

LLMs are often used for text annotation, especially in social science. In some cases, this involves placing text items on a scale: eg, 1 for liberal and 9 for conservative

There are a few ways to accomplish this task. Which work best? Our new EMNLP paper has some answers🧡

AI is already at work in American newsrooms.

We examine 186k articles published this summer and find that ~9% are either fully or partially AI-generated, usually without readers having any idea.

Here's what we learned about how AI is influencing local and national journalism:

"AI slop" seems to be everywhere, but what exactly makes text feel like "slop"?

In our new work (w/ @tuhinchakr.bsky.social, Diego Garcia-Olano, @byron.bsky.social ) we provide a systematic attempt at measuring AI "slop" in text!

What are your favorite recent papers on using LMs for annotation (especially in a loop with human annotators), synthetic data for task-specific prediction, active learning, and similar?

Looking for practical methods for settings where human annotations are costly.

I see this work as our answer to the "cultural alignment" and "cultural benchmarking" trends in NLP research. Instead of making decisions for people, we consider "culture" in a specific setting with specific people for a specific task, and we ask people directly about their cultural adaptations.

Room for improvement:

πŸ”§ Frankentexts struggle with smooth narrative transitions and grammar, as noted by human annotators.
πŸ”© Non-fiction versions are coherent and faithful but tend to be overly anecdotal and lack factual accuracy.

Takeaway 2: Our controllable generation process provides a sandbox for human-AI co-writing research, with adjustable proportion, length, and diversity of human excerpts.

πŸ‘« Models can follow copy constraints, which is a proxy for % of human writing in co-authored texts.

Takeaway 1: Frankentexts don’t fit into the "AI vs. human" binary.

πŸ“‰ Binary detectors misclassify them as human-written
πŸ‘¨β€πŸ‘©β€πŸ‘§ Humans can detect AI involvement more often
πŸ” Mixed-authorship tools (Pangram) help, but still catch only 59%

We need better tools for this gray zone.

Automatic evaluation on 100 Frankentexts using LLM judges, text detectors, and a ROUGE-L-based metric shows that:

πŸ’ͺ Gemini-2.5-Pro, Claude-3.5-Sonnet, and R1 can generate Frankentexts that are up to 90% relevant, 70% coherent, and 75% traceable to the original human writings.

Frankentext generation presents an instruction-following task that challenges the limits of controllable generation, requiring each model to:

1️⃣ Produce a draft by selecting & combining human-written passages.
2️⃣ Iteratively revise the draft while maintaining a copy ratio.

πŸ€” What if you gave an LLM thousands of random human-written paragraphs and told it to write something new -- while copying 90% of its output from those texts?

🧟 You get what we call a Frankentext!

πŸ’‘ Frankentexts are surprisingly coherent and tough for AI detectors to flag.

Aligning the validator and generator rankings can fix it!

Aligning the validator and generator rankings can fix it!

One of the ways that LLMs can be inconsistent is the "generator-validator gap," where LLMs deem their own answers incorrect.

🎯 We demonstrate that ranking-based discriminator training can significantly reduce this gap, and improvements on one task often generalize to others!

A very cool paper shows that you can use the RL loss to improve story generation by some clever setups on training on known texts (e.g. ground predictions versus a next chapter you know). RL starting to generalize already!

The high effort solution is to use an LLM to make a browser extension which tracks your academic reading and logs every paper you interact with to github, which builds and publishes a webapp to expose the data.

Which, clearly only a crazy weirdo would do.
