About Gus Hahn-Powell

I am an Assistant Professor in the Department of Linguistics.  I also hold appointments in the Cognitive Science GIDP and the Computational Social Science Graduate Certificate Program.  My research centers around machine reading for scientific discovery.  In other words, I build and design intelligent systems to help researchers surmount the problem of information overload by scouring the vast body of scientific literature, analyzing findings, and synthesizing discoveries to generate novel hypotheses.  Please see my website for details on my research and teaching.

Projects

The following is a partial list of projects I either authored or made significant contributions to while a grad student...

• Influence Search
  • very early version: visualization of causal connectivity of events automatically extracted from biology papers
• py-processors (Python wrapper for the CLU Lab's processors NLP library)
• processors-server (RESTful, actor-based web app exposing core functionality of processors)
• REACH (domain-specific machine reading system developed for the DARPA Big Mechanism program)
  • assembly system for machine read statements describing biomolecular events
• rule-based event extraction
  • loki
  • Odin (Open Domain INformer) framework for EE
  • Odin manual (v. 1)
  • Odin tutorial
  • open domain demo
  • cancer biology demo
• scala utilities for detecting rhymes, stress patterns, poetic devices, etc
• web app for tracing contours in ultrasound images
• autotres
• simplistic morphological analyzer for English

Really, really old stuff:

• COCA Tutorials (geared toward ESL students and teachers)
