Machine-translated · View original
A lab that studies communication understanding, connecting people through language and supporting them through information.

AboutAbout the lab
Connecting through language, supporting through information
The Communication Understanding Lab studies the process of human language understanding, as well as the understanding of communicative intent that connects people and communities.
The lab also works on "norm-mediating alignment," which mediates multilayered norms spanning individuals, organizations, groups, and cultures.
Its research rests on information access, which supports access to social information, and on natural language processing, which aligns large language models with the norms of people and society.
The lab welcomes motivated non-degree research students and undergraduates, and invites them to start by coming to an open lab or a lab visit.
