Re: NLP question tonight


Hi Joe,

Thanks a lot for following up on this.  The Tech Talk video looks very interesting.

A professor at Penn actually pointed me to General Inquirer a few years back and asked me to process a ton of NYT articles for positive and negative sentiment.  I remember access to it being complex and having to exchange several e-mails with its administrators to resolve errors.  Unfortunately, I don't remember how well the results turned out.

If I recall correctly, we ended up using LIWC to process the articles:  http://www.liwc.net/

Thanks again,
