Estimating demographics from internet activity

Question

I'm looking for research papers on estimating demographic information (age, wealth, location, gender etc.) out of internet activities (preferably social network activity or browser history).

Where would be a good place to look for?

Answer 1

Last summer, Kaggle ran a competition to predict a users psychopathy, Machiavellianism, Narcissism etc. using only Twitter data. You can see the competition and results here:

1. personality competition
2. psychopathy

I recall there was a published paper on the psychopathy prediction, here: http://www.onlineprivacyfoundation.org/research_/Sumner_Predicting_Dark_Triad_Traits_from_Twitter_Usage_V5.pdf

Answer 2

Stuff that I found so far:
Demographic Prediction Based on User’s Browsing Behavior
A Machine Learning Approach to Twitter User Classification
Classifying Latent User Attributes in Twitter
