I notice your blog is filled with NLP related goodies. I've been meaning to screw around with Stanford NER lib, to see if i can train up some custom recognizers for particular document domains of any utility.
I worked on a bunch of products, but the longest term one was the a side-product to WestLaw, Firm360, which was a market research tool for law firms that came from an acquisition (FindLaw). I worked on some of the data-warehousing stuff, and got to talk to a lot of people who worked on the content side. There were some teams near me that did similar things (People Map / KeyCite).
Thank you for posting this and for your hard work at TR. I'm developing something related to this stuff - http://youtu.be/3m194rui52Q (it's a really old video!)
