PAN Competition 2015: Plagiarism Detection, Author ID, Author Profiling

Take part in one of 3 tasks: Plagiarism Detection - given a document, is it an original? Author Identification - given a document, who wrote it? Author Profiling - given a document, what is author age / gender?

PAN 2015 PAN 2015: Call for Participation

We invite you to take part in one of the following shared tasks:

1. Plagiarism Detection -- Given a document, is it an original?
This task studies source retrieval and text alignment, i.e. retrieving likely sources of a suspicious document, and aligning reused passages of text between them.

2. Author Identification -- Given a document, who wrote it?
This task focuses on authorship verification and methods that tell us whether two given documents have the same author; a frequent challenge of forensic linguistics.

3. Author Profiling -- Given a document, what are its author's personal traits?
This task is about predicting an author's demographics from her writing. It will include various data sets, including reviews and Twitter tweets. Besides age and gender, a new data set will be introduced to study the predictability of an author's personality.
