Análise de técnicas e ferramentas de detecção de plagio, e desenvolvimento de um protótipo de nova ferramenta

Abstract

Plagiarism is a growing problem in the academy because it breach intellectual property, reduces student learning, etc. As a way to inhibit this practice, several tools for detecting plagiarism, some focused on detecting plagiarism of source code and other of text documents, have emerged. This article describes qualitative and quantitative analysis of the main tools for plagiarism detection in text documents. Qualitative analysis describes and compares the main features offered by the tools, whereas quantitative analysis apply tests of efficiency, sensitivity and performance in order to establish a comparative table. After analysis, we carry out modelling and implementation of a prototype for plagiarism detection. The prototype is able to identify similarities between documents suspected to present documents on the web through the search engine Microsoft BING.
