Language Interaction Lab

We are the Language Interaction Lab at the Siebel School of Computing and Data Science at the University of Illinois Urbana-Champaign.

We work at the intersection of Natural Language Processing and Human-Computer Interaction. We design human-centric AI systems that make it easier for more people to communicate, share and understand expert knowledge. This includes evaluating the ability of AI to communicate complex concepts to diverse audiences and building interactive tools that augment how people read, write, and listen in knowledge-intensive fields like medicine, law, and science.

Living Contracts: Beyond Document-Centric Interaction with Legal Agreements

April 8, 2026 · Ziheng (Fred) Huang

We regularly sign legal contracts for where we live, who we work with, and the services we use. But our interaction with them has largely been limited to document reading — complicated by extended, complex, and ambiguous legal language...

TermSight: Making Service Contracts Approachable

April 8, 2026 · Ziheng (Fred) Huang

We regularly click "Agree" to Terms of Service that quietly govern our data and rights. Most people don't fully understand what they're signing — not because they don't care, but because ToS are presented in a form misaligned with how humans process information...
