An XML plagiarism detection algorithm for Procedural Programming Languages

This paper mainly studies an XML plagiarism detection algorithm for Procedural Programming Languages. Picking out the key structure which can represent the procedural structure from C language; designing the algorithm of generating an XML text from program code; according to the different key structure and corresponding means of plagiarism, designing the different similarity comparison algorithm of XML text line; according to the similarity of XML text line, designing the procedural similarity comparison algorithm. Finally the usefulness of the plagiarism detection algorithm is discussed.
