The PAN-PC-11 can be used to evaluate the following retrieval task:

  • External Plagiarism Detection. Given a set of suspicious documents and a set of source documents, the task is to find all plagiarized sections in the suspicious documents and their respective source sections in the source documents.
  • Intrinsic Plagiarism Detection. Given only a set of suspicious documents, the task is to identify all plagiarized sections, e.g., by detecting writing style breaches. The comparison of a suspicious document with other documents is not allowed in this task.

The PAN-PC-11 contains documents in which plagiarism has been inserted automatically as well as documents in which plagiarism has been inserted manually. The former have been constructed using a so-called random plagiarist, a computer program which constructs plagiarism according to a number of parameters, while the latter have been obtained with crowdsourcing via Amazon's Mechanical Turk.

A detailed description of the corpus construction can be found in the associated publication.
