US 10,949,611 B2 · Using computer-implemented analytics to determine plagiarism or heavy paraphrasing

Abstract

Current plagiarism checkers can determine if a document has extensively copied from another but these checkers fail when a document is filled with synonyms. The present invention offers a means of detecting plagiarism involving the use of synonyms or heaving paraphrasing. A source passage from a pertinent corpus is modified by generating augmented tokens which include synonyms for the various terms in the passage. Text analysis may be required to confirm the semantic meaning of a term. The modified passage may be a regular expression. The modified passage can then be compared to a suspect passage using a trigram scorer. If possible plagiarism is detected, an alert message is sent to a reviewer with the passage of interest, the source passage, and an identification of the related corpus.

Dependent claims

A method of detecting plagiarism comprising:

receiving a passage of interest, by executing first instructions in a computer system;
receiving a corpus having a source passage wherein the corpus is related to the passage of interest, by executing second instructions in the computer system;
associating at least one synonym with a term in the source passage, by executing third instructions in the computer system;
creating a modified passage using the synonym wherein the modified passage has an augmented token which includes the term and the at least one synonym, by executing fourth instructions in the computer system;
comparing the modified passage to the passage of interest to determine that the modified passage is similar to the passage of interest, by executing fifth instructions in the computer system;
and
responsively providing an indication that the passage of interest is likely plagiarized, by executing sixth instructions in the computer system.
