The CliPA corpus has been created as a resource for the design and test of methods for the automatic detection of cross-lingual plagiarism cases. It contains a set of original text fragments in English and around twelve different plagiarised versions of them in Spanish (Italian will be added soon). The plagiarised text fragments were obtained by both “human plagiarisers” and Machine Translators. In order to create a realistic plagiarism detection environment, the corpus includes a set of text fragments on the same topic but originally written in Spanish.

Due to the facts that all the text fragments in the corpus are identified as original or plagiarised and that the plagiarised fragments are linked to their actual source, the corpus can be used to develop and test cross-lingual plagiarism detection methods.

The corpus is codified in XML.

There are not special requirements to use the corpus. It can be accessed via any XML parser.

To our knowledge, With respect, CLiPA corpus is the only freely available corpus cross-lingual plagiarism analysis.

Developed as part of the MiDES CICYT TIN2006-15265-C06-04 research project.
