How Does Plagiarism Checker Work?

The plagiarism detector utilizes advanced algorithms and Natural Language Processing (NLP) techniques to carefully analyze your text and detect various types of plagiarism. The process involves the following steps:

Input Text and Preprocessing

User pastes or uploads text into the duplichecker's text box. After that, the plagiarism checker removes formatting, punctuation errors, and unnecessary elements to prepare it for a deep analysis.

Deep Scan with Billions of Database Sources

The system compares the input text against an extensive database that includes websites, articles, journals, eBooks, research papers, and previously published work to identify similar write-ups.

Word Frequency Analysis

It breaks down the text into words and checks the frequency of their occurrence. It helps the algorithm detect unusual similarities and patterns that may indicate plagiarism.

Phrase Matching

Besides looking at individual words, this plagiarism checker identifies repeated phrases and sentence structures to accurately flag copied text.

Similarity Measurement

The text then goes through a similarity index that measures how closely the input text resembles the matched sources.

Semantic Analysis

This plagiarism detector then leverages AI-driven semantic analysis to understand the meaning behind sentences, which allows it to detect paraphrased plagiarism.

Highlight Duplication

Once copied content is detected, the duplicate checker highlights the plagiarized parts to make it easy for users to identify the problematic sections.

Plagiarism Report Generation

Finally, the similarity checker generates a downloadable plagiarism report. This report includes a percentage of uniqueness, links to matched sources, and highlighted sections that require revision.

Why Plagiarism Matters?

Plagiarism is considered an intellectual theft in academic and professional careers. This unethical act might not bother you as long as you become its victim. If you have put days of hard work into curating a research paper and someone else is getting its credit, this will surely make you furious and urge you to take strict action.

Similarly, if you plagiarize anyone’s content, you will have to bear severe consequences. That’s why understanding plagiarism matters a lot and should be avoided at all costs. If not, then you may soon find yourself in big trouble. For instance, a student may get suspended from the institute if proven guilty of plagiarizing.
