ABSTRACT: Various approaches for plagiarism detection exist. All are based on more or less sophisticated text analysis methods such as string matching, fingerprinting or style comparison. In this paper a new approach called Citation-based Plagiarism Detection is evaluated using a doctoral thesis, in which a volunteer crowd-sourcing project called GuttenPlag identified substantial amounts of plagiarism through careful manual inspection. This new approach is able to identify similar and plagiarized documents based on the citations used in the text. It is shown that citation-based plagiarism detection performs significantly better than text-based procedures in identifying strong paraphrasing, translation and some idea plagiarism. Detection rates can be improved by combining citation-based with text-based plagiarism detection.

ABSTRACT: Extracting titles from a PDF’s full text is an important task in information retrieval to identify PDFs. Existing approaches
apply complicated and expensive (in terms of calculating power) machine learning algorithms such as Support Vector Machines
and Conditional Random Fields. In this paper we present a simple rule based heuristic, which considers style information (font
size) to identify a PDF’s title. In a first experiment we show that this heuristic delivers better results (77.9% accuracy)
than a support vector machine by CiteSeer (69.4% accuracy) in an ‘academic search engine’ scenario and better run times (8:19
minutes vs. 57:26 minutes).
