摘      要：Experts in intellectual property litigation have used the commercial version of Code-Match to search for plagiarized source code. CodeMatch makes use of knowledge of programming languages and program structures. The demo version compares two files and lists all their similarities as determined by the five algorithms. The commercial version compares lots of files in different directories and ranks them according to most similar pairs. The CodeMatch Semantic Sequence Matching algorithms compares the first word of every source line in the pair of files, ignoring blank lines and comment lines.
