    abstract="Employing paraphrasing tools to conceal plagiarized text is a severe threat to academic integrity. To enable the detection of machine-paraphrased text, we     evaluate the effectiveness of five pre-trained word embedding models combined with machine learning classifiers and state-of-the-art neural language models. We analyze preprints of research papers, graduation theses, and Wikipedia articles, which we paraphrased using different configurations of the tools SpinBot and SpinnerChief. The best performing technique, Longformer, achieved an average F1 score of 80.99{\%} (F1=99.68{\%} for SpinBot and F1=71.64{\%} for SpinnerChief cases), while human evaluators achieved F1=78.4{\%} for SpinBot and F1=65.6{\%} for SpinnerChief cases. We show that the automated classification alleviates shortcomings of widely-used text-matching systems, such as Turnitin and PlagScan.",

This is the checkpoint for Longformer-base after being trained on the Machine-Paraphrased Plagiarism Dataset

Additional information about this model:

The model can be loaded to perform Plagiarism like so:

from transformers import AutoModelForSequenceClassification, AutoTokenizer


input = "Plagiarism is the representation of another author's writing, \
thoughts, ideas, or expressions as one's own work."

example = tokenizer.tokenize(input, add_special_tokens=True)

answer = model(**example)
# "plagiarised"
