Source Retrieval for Plagiarism Detection from Large Web Corpora: Recent Approaches.
Matthias Hagen, Martin Potthast, Benno Stein · 2015
Abstract This paper overviews the five source retrieval approaches that have been submitted to the seventh international competition on plagiarism detection at PAN 2015. We compare the performances of these five approaches to the 14 methods submitted in the two previous years (eight from PAN 2013 and six from PAN 2014). For the third year in a row, we invited software submissions instead of run submissions, such that cross-year evaluations are possible. This year’s stand-alone source retrieval overview can thus to some extent also be used as a reference to the different ideas presented in the last three years—the text alignment subtask will be depicted in another individual overview. 1
