Tools and resources
Spatiotemporal parser for fuzzy time and location expressions. Our prototype widens the definition of time to include descriptors like “simultaneously”, and “daily”, etc., and the definition of location to include descriptors like “near the end”.Prototype
Metonym Detector for Location: Our prototype determines whether the location entity found in English text represents a physical location (Champagne the region in France) or a metonymic substitution of location word for a person, organization or product (Champagne in a bottle) Prototype
Language Bridge is a multi-lingual location-time-person extractor. It is currently set up for English, Chinese, Arabic, Bahasa Indonesia, and Russian, but dozens of other languages can be added easily. Screen shot We are working on a timemap dislay to cluster person, location and time.
Geolocator software extracts location entities from tweets and text, and attaches geographic coordinates to each location. The Geolocator 3.0 is a core component of our LanguageBridge software. Geolocator 2.0
METAL = Metaphor Extraction via Targeted Analysis of Language, software to extract metaphors in multi-lingual text. My team’s interface shows contrasts in cultural values about certain topics as reflected in metaphor. In the dislay, a flag represents the country of origin of a metaphor, and clicking on the flag displays text source. Screen shot
ORA = Organizational Risk Analyzer. It is a meta-network assessment tool developed at the CASOS lab, for which my team contributed the code for geolocation capabilities in 2011. *ORA
My background
I have done pure research since 2008 in the Language Technologies Institute in the School of Computer Science at Carnegie Mellon University. I supervise undergraduates, graduate students and (soon) a postdoctoral fellow on research in areas of geo-data mining, geo-information retrieval and visualization, and design of systems to reduce visual mistakes. My PhD in information science came from Rutgers University, where I worked with Professor Michael Lesk in a dissertation pertaining to maps. My B.A. from Yale University is in medieval history and culture, my A.M. from Harvard University is in fine arts, and my M.S. from Simmons is in information science.
