We propose a new computational approach for tracking and
detecting statistically significant linguistic shifts in the mean-
ing and usage of words. Such linguistic shifts are especially
prevalent on the Internet, where the rapid exchange of ideas
can quickly change a word’s meaning. Our meta-analysis
approach constructs property time series of word usage, and
then uses statistically sound change point detection algo-
rithms to identify significant linguistic shifts.
