How to do plagiarism check?4 answersTo conduct a plagiarism check effectively, one can utilize various methods and technologies outlined in the provided research contexts. One approach involves using an integrated viewer system that allows users to easily identify plagiarism by comparing original and converted electronic documents on a single screen. Another method involves calculating partial similarities between documents based on free word order languages like Hangul or Japanese, and determining plagiarism levels by considering both preliminary and in-depth similarities. Additionally, blockchain technology can be employed to detect plagiarism in non-fungible token (NFT) images using deep learning models like EfficientNet-B0 with triplet semi-hard loss function, which outperforms other traditional models. These techniques offer efficient ways to detect plagiarism in various types of documents and digital assets.
What are the most common methods used to detect plagiarism in academic writing?4 answersThe most common methods used to detect plagiarism in academic writing include lexical, syntactical, and semantic text similarity analysis, as well as the incorporation of Natural Language Processing (NLP) techniques. These methods aim to identify copied, reworded, translated text, and even disguised forms of plagiarism like strong paraphrases and sense-for-sense translations. Plagiarism detection systems often rely on string-level comparisons between suspicious and authentic texts, utilizing NLP techniques to enhance accuracy in identifying plagiarism. Additionally, academic misconduct detection methods have evolved to consider scholars' submission behaviors alongside text content analysis, improving the detection of various types of misconduct. Furthermore, advancements in NLP have led to the development of novel approaches that generate multiple paraphrased versions of a given text, enhancing the accuracy of plagiarism detection in academic settings.
What are some tools to check for plagiarism in an essay for free?4 answersThere are several tools available for checking plagiarism in an essay for free. One method is to use Google's "exact word or phrase" search, where the user can copy a portion of text and search it on Google with the text in quotes. This allows Google to search for the exact words and phrases in the exact order. Another option is CrossCheck, which is widely used for texts in English. AMLC (Academic Manuscript Literature Checking) from CNKI is another tool that is mainly used for texts in Chinese. Ferret and Sherlock are two free/open source tools that can be used for detecting plagiarism. Turnitin is a commercial web-based software that can also be used for plagiarism detection. Additionally, there are online paraphrasing tools and language translation tools that can be used to test the outputs of these tools.
How natural language processing support plagiarism check?5 answersNatural language processing (NLP) techniques are used to support plagiarism check by improving the accuracy of plagiarism detection tools. These tools primarily rely on string-level comparisons between suspicious texts and potential original work. By incorporating NLP methods, the detection methods can analyze the structure, semantics, and linguistic variations of the texts, making them less susceptible to changes in grammar or word replacements. NLP techniques, such as syntactic-semantic based linguistic structures, part of speech tags, chunks, and semantic roles, are utilized to extract relevant information and compare the similarity between documents. The use of NLP in plagiarism detection has shown considerable improvement in identifying plagiarism, even in cases where traditional methods fail.
How effective are plagiarism checkers in detecting plagiarism?4 answersPlagiarism checkers have been used in various studies to detect plagiarism in academic papers. One study found that around 22.8% of submitted papers contained unreasonable levels of copying or self-plagiarism. Another study used Apache Lucene to detect plagiarism by comparing the plagiarized document with a set of previously saved documents using cosine similarity. A different approach involved calculating numerical values for each sentence in a document and comparing them to values determined for archive documents. However, it is important to note that software alone may not always catch recycled text, and careful reading by academics and editors is still necessary. To address the need for an effective and feasible approach, a text mining method using Term Frequency-Inverse Document Frequency (TFIDF) and Latent Semantic Indexing (LSI) was proposed to semantically find plagiarism in research papers.
How to check ai in research paper?5 answersTo check AI in research papers, various methods and techniques can be used. One approach is to analyze the AI technology keywords extracted from patent documents using text mining techniques and partial least square (PLS) regression model. Another method involves comparing human detection with AI detection to determine the accuracy in identifying fabricated research works. Additionally, scientometric and bibliometric analysis can be conducted to explore the importance of AI, machine learning, deep learning, and data mining in self-driving car research and development. Viewing an AI system as a model can also provide criteria for testing methodologies, including mathematical techniques and testing of individual system components. Furthermore, the benefits of AI in medicine can be analyzed, such as its assistance in diagnosing diseases, patient treatment, reducing errors, and virtual presence with patients.
