A new research paper explores how editorial interventions, particularly those involving large language models, affect the ability to identify an author's native language (L1) from their writing. The study found that while surface-level errors are less critical, deeper linguistic features like unidiomatic word choices and pragmatic transfer are more indicative of L1. Minimal edits preserve these traces, allowing for high L1 attribution accuracy, whereas fluency edits and paraphrasing significantly degrade performance. AI
