Joint Human–AI Systems: Programming & Events

TDAI’s Joint Human–AI Systems theme explores how people and AI collaborate in real work—analysis, decision-support, and action—focusing on reliability, accountability, and human values. Below you’ll find upcoming seminars, workshops, and discussions hosted under this theme.

Upcoming Workshops

Detecting and Characterizing AI Use in Collaborative Writing

Speaker: Dr. Mohit Iyyer (University of Maryland)
Date: Tuesday, November 18, 2025
Time: 4:00–5:00 PM (ET)
Location: Pomerene Hall Room 350 (Project Zone)
Format: Research Seminar (Open to all; no registration required)

Description

Nowadays, many writers rely on AI to help produce text—sometimes for grammar and fluency, and sometimes to generate entire passages. Recent research suggests that approximately 9% of newly published American newspaper articles are now produced partially or entirely by large language models (LLMs). Yet most of this AI involvement goes undisclosed, raising concerns around transparency, public trust, authorship, and accountability.

This talk will examine the broad spectrum of AI-assisted writing, ranging from light editing to the generation of large amounts of content. We will consider when AI assistance may be acceptable to a reader—and when it may not—especially in cases where the role of AI is hidden.

Dr. Iyyer will then discuss methods for post-hoc detection:
Given a piece of text, can we tell how much AI contributed to its writing?

The talk will introduce “Frankentexts”, a new form of text generation in which an LLM generates the ideas for a piece but then repurposes fragments of human-written text to construct the final output. This method complicates detection and raises higher-level questions for copyright, creativity, and the boundaries of authorship.

The talk will conclude with ongoing work that connects AI detection research to broader questions about memorization, originality, and creative contribution in human–AI writing partnerships.
