摘要

PURPOSE: A method for searching a plagiarism of a program source and a system for marking a programming homework using the same are provided to enhance an education effect through the plagiarism prevention by easily checking the plagiarism of the programming homework. CONSTITUTION: A client(20) receives/transmits a program to a server(10) by connecting to the server through the Internet. A keyword database(30) stores a keyword similarity matrix evaluating the similarity between the keywords defined by a program language. A program database(90) stores the program received from the client. A linear order database(40) stores a linear order converted by parsing the program source and extracting the keywords. A result database(50) stores a parsing result and a marking result. A parsing module(60) extracts the keyword by parsing the program, converts the keyword into the linear order, and stores the linear order in the linear order database. A similarity calculating module(70) calculates the similarity. A marking module(90) judges the plagiarism depending on the similarity and stores the result in the result database.
