Desenvolvimento de uma ferramenta que analisa a similaridade de textos em tempo real

Abstract

Plagiarism represents a significant challenge in the creation of academic and scientific work, being not only an unethical practice, but also an illegal one, undermining the integrity of good research practices. To address this problem, the Plagiarism Search Alert tool was developed, which helps the academic community to prepare texts more effectively and accurately, avoiding plagiarism and accidental errors. Content-based plagiarism detection techniques are widely used to identify similarities between texts. Unlike existing tools, for example, Duplichecker, Plagiarism Detector, Turnitin, among others, which analyze the text only after it is written and sent to platforms, the tool developed in this work performs processing and analysis in real time, alerting the author about the results found (similar texts) while the document is written. The test results demonstrated the effectiveness of the “Plagiarism Search Alert” tool in identifying similarity between texts. In “Test Category 1”, in which the paragraphs were directly taken from internet sources and stored in the tool's text bank, they present similarity rates that reached 100%, demonstrating the accuracy of plagiarism detection. In “Test Category 2”, the paragraphs tested, involved a combination of words from sentences collected from the internet and stored in the text bank and with original words not stored in the text bank, the similarity rates varied, reflecting the capacity of the tool of identifying variations in similarity. In “Test Category 3”, composed mainly of original words not stored in the text bank, the similarity rates were lower, demonstrating the tool's ability to recognize genuinely new content. With this tool, students, teachers and researchers receive immediate feedback on the originality of their work, allowing them to learn from their mistakes and improve their research and writing skills. In addition to preventing plagiarism, it will encourage the adoption of good proposals that make a valuable contribution to the academic community, helping it to maintain high standards of integrity and quality in its academic productions.
