Abstract

With the growth of resources available to students and various machine translation tools and techniques, cross-language plagiarism has become a serious problem. The majority of the available plagiarism detection tools are developed for English Language and are not able to accurately detect paraphrasing and/or translation-based plagiarism in Indian regional languages like Hindi and Punjabi. Hindi and Punjabi are similar languages but written in different scripts (Devanagari vs. Gurmukhi), so existing text-making techniques are not effective to detect plagiarism in these languages. In this paper a hybrid cross-language plagiarism detection is proposed for Hindi and Punjabi that uses a cascade machine translation pipeline which consists of dictionary-based translation, Example-Based Machine Translation (EBMT), Neural Machine Translation, and then multilingual sentence embeddings and FAISS index is used to perform fast semantic similarity search. The proposed system accepts Hindi text or uploaded documents, generates sentence embeddings, and compares them with a Punjabi corpus using cosine similarity. The proposed system also translates the Hindi text into Punjabi and then searches the translated Punjabi text against internet sources using Google Search API. The complete system is implemented as a Flask-based web application with modules for document upload, corpus management, plagiarism history, and sentence-based search. Experimental evaluation shows that semantic similarity-based plagiarism detection is more effective than traditional string-matching approaches, as it captures the semantic meaning of translated and paraphrased text rather than relying solely on lexical overlap.

Full Article/Conclusion

This paper discussed a hybrid semantic cross language plagiarism detection system for Hindi and Punjabi language. The proposed framework combines dictionary-based translation, Example-Based Machine Translation (EBMT), Neural Machine Translation (NMT) and sentence-level semantic similarity in a single Web application. This system is capable of uploading documents, management of the document corpus, keeping the document plagiarism history, and search results with the semantic approach which is an effective solution to the detection of translated plagiarism in Indian languages. Experimental results show that using semantic sentence embeddings is better than traditional keyword-based approaches for the detection of translated and paraphrased content.
