Welcome to my CMU home page, which I update sporadically. You're better off looking at my LinkedIn profile, my slides on SlideShare, my blog, my book on faceted search, or TunkRank.
I am a co-founder and member of the steeting committee for the symposium on Human-Computer Interaction and Information Retrieval (HCIR), held annually since 2007. I've also organized industry tracks and workshops at SIGIR 2009, WSDM 2010, CIKM 2011, and RecSys 2012.
I've also presented at SDM 2002, CIKM 2004, SIGIR 2006, SIGIR 2007, ECIR 2008, SIGMOD 2009, ISSS 2009, RecSys 2011, and RecSys 2012, and CIKM 2012.
Finally, I have participated in a number of industry practitioner conferences in the areas of enterprise search, text analytics, big data, and the semantic web.
Before discovering the joys of search, I worked on graph layout (aka graph drawing), which can generously be called information visualization.
You can find my demonstration applet for JIGGLE (Java Interactive Graph Layout Environment) here, my dissertation
here,
and the source
code here.
The source code is available for both non-commercial and commercial
use; I only ask that you acknowledge the use of the software and let
me know that you are using it. Besides, you might actually get me to
help you with it that way!
You might also be interested my earlier paper describing a
practical approach to drawing undirected graphs.
