This is the 5th evaluation lab on uncovering plagiarism, authorship, and social software misuse. PAN has been part of the CLEF conference in Amsterdam, The Netherlands, on September 19-22, 2011. Evaluations commenced from January till June in the three tasks shown below.
Given a document, is it an original?
This task is divided into external detection and intrinsic detection. External detection is about searching for sources of a suspicious document. Intrinsic detection is about identifying plagiarized passages via breaches of writing style.
Given a document, who wrote it?
This task incorporates authorship attribution and authorship verification. For the former, the task is to map the uncertain texts onto their true authors among candidate authors. For the latter, the task is to determine whether the given text has been written by a specific author.
Given a Wikipedia edit, is it well-intentioned?
This task is concerned with preventing "any addition, removal, or change of content made in a deliberate attempt to compromise the integrity of Wikipedia," which defines vandalism on Wikipedia. Given a set of edits on Wikipedia articles, the task is to separate the ill-intentioned edits from the well-intentioned edits.
