<p class=MsoPlainText><span lang=EN-US>The workshop shall bring together
experts and researchers around the exciting and future-oriented topics of
plagiarism detection, authorship identification, and the detection of social
software misuse. The development of new solutions for these problems can
benefit from the combination of existing technologies, and in this sense the
workshop provides a platform that spans different views and approaches. The
following list gives examples from the outlined fields for which contributions
are welcome, but not restricted to:<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>

<p class=MsoPlainText><span lang=EN-US>Background:<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>---------------------------------------------------------------------------<o:p></o:p></span></p>

<p class=MsoPlainText><span lang=EN-US>Plagiarism analysis is a collective term
for computer-based methods to identify a plagiarism offense. In connection with
text documents we distinguish between corpus-based and intrinsic analysis: the
former compares suspicious documents against a set of potential original
documents, the latter identifies potentially plagiarized passages by analyzing
the suspicious document with respect to changes in writing style.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>Authorship identification divides into
so-called attribution and verification problems. In the authorship attribution
problem, one is given examples of the writing of a number of authors and is
asked to determine which of them authored given anonymous texts. In the
authorship verification problem, one is given examples of the writing of a
single author and is asked to determine if given texts were or were not written
by this author. As a categorization problem, verification is significantly more
difficult than attribution. Authorship verification and intrinsic plagiarism
analysis represent two sides of the same coin.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>"Social Software Misuse" can
nowadays be noticed on many social software based platforms. These platforms
like Blogs, sharing sites for photos and videos, wikis and online forums are
contributing up to one third of new Web content.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>"Social Software Misuse" is a
collective term for anti-social behavior in online communities; an example is
the distribution of spam via the e-mail infrastructure. Interestingly, spam is
one of the few misuses for which detection technology is developed at all,
though various forms of misuse exist that threaten the different online
communities. <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>Our workshop shall close this gap and
invites contributions concerned with all kinds of social software misuse.<o:p></o:p></span></p>

<p class=MsoPlainText><span lang=EN-US>About the Competition on Plagiarism
Detection:<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>---------------------------------------------------------------------------<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>The detection of plagiarism by hand is a
laborious retrieval task, a task which can be aided or automatized. The PAN
competition on plagiarism detection shall foster the development of new
solutions in this respect.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>The competition divides into two tracks:<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US> * External Plagiarism Analysis. Given
a set of suspicious documents and a set of potential source documents the task
is to find all passages within the suspiscious documents which have been
plagairized from one or more of the source documents.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US> * Intrinsic Plagiarism Analysis. Given
a set of suspicious documents the task is to detect paragraphs in the documents
which have not been written by its main author. No source documents are given
in this task.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>A large corpus of artificial plagiarism
containing cases which have been obfuscated and/or translated will be released
for the competition.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>A development corpus, to be used in developing
a detection software, will be released two months before the competition
starts, a competition corpus will be used to evaluate and compare detection
softwares. The former will contain fully annotated plagiarism cases, the latter
will not.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>The succes of a plagiarism detection
software will be measured in terms of its precision, recall, and granularity.<o:p></o:p></span></p>
