Summary

This Paper studies the influence of demography over language. In other words, it tries to identify the lexical variations with respect to certain demographic attributes (race or ethnicity, socioeconomic status, language spoken etc). Modelling sociolinguistic association is a complex problem because of the large number of possible interactions involved. Using multi-output regression with structured sparsity, this method identifies a small subset of words that are most influenced by demographics and also discovers sets of demographic attributes that influence variation in lexical items.
