  abstract  = {Author profiling is the study of how language is shared by people, a problem of
	growing importance in applications dealing with security, in order to
	understand who could be behind an anonymous threat message, and marketing,
	where companies may be interested in knowing the demographics of people that in
	online reviews liked or disliked their products. In this talk we will give an
	overview of the PAN\footnote{\url{http://pan.webis.de/}} shared tasks that
	since 2013 have been organised at CLEF and FIRE evaluation forums, mainly on
	age and gender identification in social media, although also personality
	recognition in Twitter as well as in code sources was also addressed.
	In 2017 the PAN author profiling shared task addresses jointly gender and
	language variety identification in Twitter where tweets have been annotated 
	with authors' gender and their specific variation of their native language:
	English (Australia, Canada, Great Britain, Ireland, New  Zealand, United
	States), Spanish (Argentina, Chile, Colombia, Mexico,  Peru, Spain, Venezuela),
	Portuguese (Brazil, Portugal), and Arabic  (Egypt, Gulf, Levantine, Maghrebi).},
