The competition divides into two tasks:
* External Plagiarism Analysis.
Given a set of suspicious documents and a set of source documents the task is to find all text passages in the suspicious documents which have been plagiarized and the corresponding text passages in the source documents.
* Intrinsic Plagiarism Analysis.
Given a set of suspicious documents the task is to identify all plagiarized text passages, e.g., by detecting writing style breaches. The comparison of a suspicious document with other documents is not allowed in this task.
Participants may submit results for one or both of the tasks.
