PAN 2020 is now live!

PAN @ CLEF 2017


This is the 17th evaluation lab on digital text forensics. PAN will be held as part of the CLEF conference in Dublin, Ireland, on September 11-14, 2017. Evaluations will commence from January till June. We invite you to take part in any of the three tasks shown below.

Author Identification

Given a document, who wrote it?

This task focuses on author clustering and style breach detection. Author clustering will be done on short documents of paragraph length. Style breach detection has the goal of identifying breaches of writing style in longer texts.

Author Profiling

Given a document, what're its author's traits?

This task focuses on gender and language variety identification on Twitter, providing a corpus of tweets annotated with gender and language variety.

Author Obfuscation

Given a document, hide its author.

This task works against identification and profiling by automatically paraphrasing a text to obfuscate its author's style. The tasks offered are author masking and obfuscation evaluation.
