Cosine similarity (vector space model) for plagiarism detection

Mathematics written on a chalkboard

Summary: Plagiarism detection aims to identify text that has been inappropriately copied or closely paraphrased from existing sources. Among various approaches used in plagiarism detection, one fundamental method relies on the vector space model with cosine similarity as a measure of textual similarity. In this approach, documents are represented as high-dimensional vectors based on their … Read more

Jaccard similarity set-based method for plagiarism detection

Objects organised into sets wooden building blocks

Summary: Plagiarism detection is a critical task in academic and technical fields, as it involves identifying copied or closely imitated text between documents. Various techniques have been developed to tackle this problem. One widely used method is based on the Jaccard similarity coefficient – a simple yet powerful set-based approach. In this method, documents are … Read more

Fingerprinting (hash-based methods) for plagiarism detection

Fingerprinting for plagiarism detection

Summary: Plagiarism detection is a crucial task in academia and content creation, aiming to identify when text has been inappropriately copied or reused without attribution. Modern plagiarism detection methods range from straightforward string matching to sophisticated semantic analysis. One widely adopted approach is document fingerprinting, a hash-based text similarity technique that generates a compact representation … Read more

Designing assignments to discourage AI use

Studnnts in the classroom with a teacher

Summary: Artificial intelligence (AI) tools can generate essays and answers with ease. This has left educators worried about academic integrity and tempted to police student work using AI detectors. However, focusing solely on detection is a flawed approach. AI detection software is unreliable. It often flags honest work by mistake, and even OpenAI abandoned its … Read more

How teachers can use AI checker tools effectively in the classroom

Secondary school classroom

Summary: Artificial intelligence is rapidly changing the classroom, and teachers are now grappling with the rise of AI-generated student work. Tools that detect AI-written content have emerged to help educators uphold academic integrity. These tools are often called AI checker tools or AI detectors. They can be invaluable allies when used wisely. This practical guide … Read more

Fuzzy swarm logic for plagiarism detection

Fuzzy swarm logic concept

Summary: Abstract Plagiarism detection is a critical challenge in the digital age, complicated by paraphrasing, cross-language translation, and source code plagiarism that evade simple string matching. Conventional detection methods often struggle with such nuanced cases. Fuzzy swarm logic – which combines fuzzy logic’s capacity to handle uncertainty with swarm intelligence’s optimisation abilities – offers a … Read more

Quantum computing for plagiarism detection: semantic similarity and QNLP approaches

Quantum laboratory

Summary: Plagiarism detection systems play a crucial role in academia and publishing, ensuring that written work is original and properly attributed. However, these systems often struggle to identify instances of paraphrasing or ‘idea plagiarism’. In such cases, plagiarists have rephrased the same content in different words. Conventional software can catch exact text copies but frequently … Read more

Embracing AI in higher education: university policies on generative AI

University campus

Summary: Artificial intelligence has quickly become a fixture in education. Tools like ChatGPT and Bard are raising both excitement and concern across campuses. Many universities initially feared that generative AI would fuel plagiarism or undermine learning. However, a growing number of institutions have realised that if you can’t beat them, join them. Rather than banning … Read more

Source code similarity checkers: current methods and challenges

Code on a computer screen

Summary: Plagpointer plagiarism checker effectively identifies AI-generated code, code plagiarism, modified code, and licensing alerts. With one robust solution, avoid potential infringement. Source code plagiarism – the unacknowledged reuse of someone else’s code – is a persistent issue in both education and the software industry. In academia, instructors face growing class sizes and increasingly diverse … Read more

AI clones and the plagiarism problem for actors and voice artists

AI clones - a plagiarism-like problem

Summary: The idea of performers being digitally resurrected or cloned is no longer science fiction. Fans today can watch ABBA perform live in concert even though the legendary pop group’s members are in their seventies and not physically on stage. This is possible because ABBA appears as lifelike digital avatars of their younger selves, singing … Read more
