We are the Copy Cats, a group of six computer science majors at Carleton College. Our senior comprehensive project (Comps) was to automate the detection of plagiarism. Given a suspicious document (and perhaps other "source" documents to compare to), we tried to identify the sections that were plagiarized (or likely to have been). Using a combination of topics from linguistics, natural language processing, probability, data structures, and many more areas, we built a tool to aid in the process of identifying plagiarism.
