To keep things simple, all of the backend code is found in the app.py file, which we've reproduced in full below:įrom sentence_transformers import SentenceTransformer The HTML uses a template file, and the rest of the frontend is built using static CSS and JS assets. We’ve gone through the inner workings of the app, but how did we actually build it? As noted earlier, this is a Python Flask app that utilizes the Pinecone SDK.

The README contains instructions for how to run the app locally on your own machine. If you’d like to try it out for yourself, you can find the code for this app on GitHub. The endpoint returns 10 similar articles that were possibly plagiarized and displays them in the app’s UI. When users submit their article text as input, a request is made to an API endpoint that uses Pinecone’s SDK to query the index of vector embeddings. With the vector embeddings added to the database and indexed, we’re ready to start finding similar content. Finally, we insert these vector embeddings into a vector database managed by Pinecone. We use the Average Word Embeddings Model. Then, we run the articles through an embedding model to create vector embeddings-that's metadata for machine learning algorithms to determine similarities between various inputs. Next, we clean up the dataset by renaming a couple columns and dropping a few unnecessary ones. (The full dataset that this one is derived from contains over two million articles!) This dataset contains 143,000 news articles from 15 major publications, but we're just using the first 20,000. In building the app, we start with a dataset of news articles from Kaggle. However, if we were to copy and paste the text from one of the articles in our database, the results for the plagiarized article come back with a 99.99% match! To help reduce the amount of noise, the app also includes a slider input in which the user can specify a similarity threshold to only show extremely strong matches.Īs you can see, when original content is used as the search input, the match scores for possibly plagiarized articles are relatively low. Results and their match scores are then displayed to the user. When the user clicks the Submit button, this input is used to query a database of articles. The UI features a simple textarea input in which the user can paste the text from an article. Below, you can see a brief animation of the app in action. Let’s take a look at the demo app we’ll be building today. We’ll build a Python Flask app that uses Pinecone-a similarity search service-to find possibly plagiarized content.

So, how do we guard against plagiarism? Wouldn’t it be nice if we could have software do the heavy lifting for us? Using machine learning, we can build our own plagiarism checker that searches a vast database for stolen content. News outlets may want to check if a content farm has stolen their news articles and claimed the content as its own.
Teachers may want to check students’ papers against other scholarly articles for copied work. Authors writing blog posts may want to check if someone has stolen their work and posted it elsewhere. With so much content out there, it’s sometimes hard to know when something has been plagiarized. Plagiarism is rampant on the internet and in the classroom.
