Operation-Guided Progressive Human-to-AI Text Transformation Benchmark for Multi-Granularity AI-Text Detection

arXiv:2606.06481v1 Announce Type: new Abstract: As AI writing assistants become increasingly integrated into real-world drafting and revision workflows, many documents are no longer purely human-written or AI-generated, but instead result from progressive human-AI co-editing. However, existing AI-text detection benchmarks largely focus on final outputs and provide limited understanding of how AI authorship signals emerge, accumulate, or disappear throughout the revision process. We introduce OpAI-Bench, an operation-guided benchmark for studying progressive human-to-AI text transformation acro

Why this matters
Why now

The increasing sophistication and integration of AI writing assistants necessitate new methods for detecting AI authorship in co-edited documents, moving beyond simple final output analysis.

Why it’s important

This development is crucial for maintaining academic integrity, ensuring transparency in content creation, and refining intellectual property frameworks in an age of human-AI collaboration.

What changes

The focus of AI-text detection shifts from binary classification of final outputs to a more nuanced, process-oriented understanding of how AI contributions evolve during revision.
