Measuring self-focus bias in community-maintained knowledge repositories
TLDR
Two methods to quantify self- focus are outlined, one of which is very computationally inexpensive, and empirical evidence for the existence of self-focus is presented using a "hyperlingual" approach that examines 15 different language editions of Wikipedia.
