Online Plagiarism Tool Adds PDF Support


Online plagiarism detection service DOC Cop has expanded its offerings again, adding support for PDF files to its free document checking tools. This includes the ability to check PDF files against other PDFs or against Word documents.

DOC Cop is a Web-based service that provides free plagiarism detection tools, as well as paid document checks. It includes DOC Check, which evaluates individual documents--up to five at a time, 250,000 word maximum each--against one another; Corpus Check, which evaluates an unlimited number of documents (up to 12,000 words each) against one another; Web Check Free, which checks document segments against Web results for free, with a limited number of checks per day, no concurrent checks, and up to 150 words per submission; and Web Check Paid, which checks up to 2,000 words per submission with unlimited checks per day and allows concurrent submissions (AUS$5 per check).

The expanded PDF support is available for the free DOC Check and Corpus Check services. (PDF was already available through Web Check.) PDF files to be checked must contain text, rather than scanned images of text.

In addition to the expanded PDF support, both DOC Check and Corpus Check now support line breaks and "improved navigation for large documents," according to the company. More information is available at the link below.
