Today's plagiarism detectors face intricate situations, such as paraphrased plagiarism within and across languages. Moreover, the source of a plagiarism case may be hidden within a large collection of documents such as the Web, or it may not be available at all. Building on the successful evaluation framework developed in the last two years, we continue to add new challenges this year.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt'>- Author Identification. Throughout history and especially today, many texts are written anonymously or under false names, so that readers may not be certain of a text's alleged author. Author identification is the task determining the true author of a text, and one of the main challenges is to automatically attribute a text to a set of known authors. For the purpose of the evaluation, we have developed a new authorship evaluation corpus. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt'>- Wikipedia Vandalism Detection. Vandalism has always been one of Wikipedia's biggest problems. However, the detection of vandalism is done mostly manually by volunteers, and research on automatic vandalism detection is still in its infancy. Hence, solutions are to be developed which aid Wikipedians in their efforts.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt'>PAN is organized by the Bauhaus-Universität Weimar, the Universidad Politécnica de Valencia, the University of the Aegean, the Bar-Ilan University, the Illinois Institute of Technology, and the Duquesne University.<span style='color:blue'> </span><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt'>For more information see <a href="http://pan.webis.de/"><span style='color:windowtext;text-decoration:none'>http://pan.webis.de/</span></a>.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt'>LogCLEF<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt'>---------<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt'>The research goal of LogCLEF is the analysis and classification of queries in order to understand search behaviour in multilingual contexts, and it consists of three tasks: 1) Language identification task; 2) Query classification, 3) Success of a query. In coordination with the organizers, participating groups will be devoted to different tasks in exploring and understanding the data. For some of these tasks, test sets of human labelled queries (a subset from the log files) should be assembled and released to the participants. In order to create an interesting test and training set, participants will be required to submit both manual and automatic annotations.

The task consists of the reading of single documents, where correct answers require some inference and previously-acquired background knowledge. Like in Reading Comprehension Tests, questions will be in the form of multiple choice questions.

The combination of these two sources of information is still under-investigated in music retrieval. To this end, MUSICLEF aims at developing and maintaining a test collection of both music files and relevant desciptors, to be distributed to participants in the form of feature vectors (e.g. MFCCs,
