DESCRIPTION:Language is constantly changing\, and at any given time there 
 is variation within and between groups. Social media has opened up excitin
 g opportunities to study language variation and change at scale.  First\, 
 I will present a study on measuring semantic change in Twitter using word 
 embeddings on a corpus spanning 5.5 years. Second\, I will present a study
  on measuring geographical language variation based on Reproducing Kernel 
 Hilbert space (RKHS) representations. In both studies the lack of ground t
 ruth poses evaluation challenges. I will discuss results on both synthetic
  and empirical data.\n
