Simple-Plagiarism-Checker

Web application of Plagiarism Checker using Python-Flask. TF-IDF and cosine similarity is a very common technique. It allows the system to quickly retrieve documents similar to a search query. Similarly, based on the same concept instead of retrieving documents similar to a query, it checks for how similar the query is to the existing database file.

Example

  1. Run python plag.py and open http://127.0.0.1:5000 in a browser.

  2. Type or paste a passage into the query text box and submit the form.

  3. The app compares the query against database1.txt using TF-IDF cosine similarity.

  4. The page refreshes and displays a result such as:

    Input query text matches 73.45% with database.

Steps:

  1. User enters a query
  2. Query gets processed (Uppercase to lowercase, Removal of punctuationmarks, etc.)
  3. Calculations are done (Term Frequency, Cosine Similarity)
  4. The Plagiarism Percentage is returned on the web page

Python-Flask

  1. Flask is a light-weight web framework for Python
  2. Easy to work with (Same syntax as of Python)
  3. While Flask addresses itself as a "micro-framework", it is not lacking in features or power, especially with a clutch of extensions to support features such as authentication, databases and so on
  4. Comprehensive documentation available
