Silicon Valley Intermission

From 2010-2011 I was on leave from UW-Madison, working as Chief Scientist of Kosmix, a startup in social media analytics. 

While at Kosmix I was involved in a number of projects that built and used Web-scale knowledge bases, especially for information extraction and integration, entity matching, and social media analytics. Parts of these projects are described in the following papers:
I also worked on event detection and monitoring for social media. A talk that describes work at Kosmix at a high level: Social Media, Data Integration, and Human Computation.

Kosmix was acquired by Walmart in 2011 and turned into WalmartLabs, the research and development lab for e-commerce at Walmart. From 2011-2014 I worked as Chief Scientist of WalmartLabs. Some of this work and collaboration efforts from 2014 until now are described here. My work/collaboration efforts involve building product knowledge bases, product matching, information extraction, data cleaning, and crowdsourcing.
