The Computational Language Understanding (CLU) Lab at
University of Arizona
is a team of faculty, students, and research programmers who work together
to build systems that extract meaning from natural language texts,
including question answering (answering natural language questions),
information extraction (extracting specific relations and events),
semantic role labeling (extracting semantic frames that model who did what to whom,
when and where), parsing the discourse structure of complex texts,
and other computational linguistics problems.
These systems were used in several applications, ranging from extracting
cancer signaling pathways from biomedical articles to automated systems for
answering multiple-choice science-exam questions.
The CLU lab includes members of both the Computer Science department
and the Linguistics department, and is led by
