| Περίληψη: | The task of intrinsic plagiarism detection deals with cases where no reference corpus
is available and it is exclusively based on stylistic changes or inconsistencies within a given
document. In this paper a new method is presented that attempts to quantify the style variation
within a document using character n-gram profiles and a style change function based on an
appropriate dissimilarity measure originally proposed for author identification. In addition, we
propose a set of heuristic rules that attempt to detect plagiarism–free documents and
plagiarized passages, as well as to reduce the effect of irrelevant style changes within a
document. The proposed approach is evaluated on the recently-available corpus of the 1st Int.
Competition on Plagiarism Detection with promising results. |
