Since the launch of ChatGPT in November 2022, the rapid development of large language models (LLMs) in artificial intelligence (AI) has made high-quality translation easy in academic research and writing. Students use AI translators like Google Translate and DeepL along with LLMs such as ChatGPT, Gemini, and Perplexity to help them produce academic papers. 

AI tools provide access to diverse learning resources, but they can affect academic integrity when misused. Students can translate source texts into different languages and retain their meaning by changing sentence structures. This makes plagiarism tougher to detect. 

To maintain academic integrity in increasingly multilingual platforms, educators need cross-language plagiarism checker sites like Plag to detect plagiarism (similar text) at the semantic level in multiple languages. 

With Plag’s AI and plagiarism checker, educators can evaluate translated work more fairly and allow the exchange of authentic, original information without penalising legitimate multilingual work.

What happens when text is translated before checking for plagiarism?

When you translate text by changing syntax, vocabulary, or idioms, a text’s sentence structure might change in a different language.  For example, “I play football” in English becomes “Lo gioco a calcio” (“I play at football”) in Italian.

When a sentence is directly translated, there are higher chances for you to detect plagiarism. However, when the translation includes semantic adaptation (different syntax, vocabulary, or idiom), basic anti-plagiarism tools might fail to detect it. 

Research by the Science and Information (SAI) Organization shows that traditional  text-matching plagiarism detectors may miss an estimated 15-45% of translated plagiarism cases. To minimise such cases, it’s increasingly vital for us to use advanced sites with semantic analysis across language features to check plagiarism like Plag.

How does Plag detect translated plagiarism more accurately?

Plag stands out as an anti-plagiarism site that detects translated plagiarism, a common blind spot for traditional plagiarism tools. Unlike basic text-matchers, it applies advanced AI to spot conceptual and contextual similarities in plagiarized texts. 

Plag is created to enhance the educators’ judgement rather than replace it. The tool highlights possible similarities in academic work so teachers and lecturers can make informed, fair decisions when assessing students’ submissions.

How does multilingual neural network detection work in Plag?

Plag uses deep learning to map conceptual similarities. The tool detects contextual equivalence between languages, where different words and sentence structures convey the same meaning when translated (not just the exact wording).

Our team of academic linguists and tech professionals has also trained Plag on different multilingual academic datasets to ensure accurate detection across 56 languages.​ The tool can understand ideas in Italian, English, and other languages simultaneously, making it ideal to verify plagiarism in different languages worldwide. 

What makes parallel data learning powerful for cross-language checks?

Parallel data comprises sentences in one language that are paired with their accurate translations in another.

Having trained on multilingual datasets from academic sources, Plag can check for plagiarism simultaneously in dozens of languages. This feature is valuable for thesis evaluation and postgraduate research, where translated sources are common and require detailed analyses.

Key benefits of a multilingual AI and plagiarism checker like Plag include:

  • Exposure to real-world translations from journals and theses
  • The ability to handle rare language pairs without accuracy drops
  • Continuous retraining on fresh data for evolving threats

Benefits of verifying if translated plagiarism exists in your thesis

By making sure your work and thesis are plagiarism-free, you get to uphold your academic integrity. As an educator, this safeguards your reputation as an academic professional with integrity. If you’re a student, turning in plagiarism-free assignments and theses provides the ideal stepping stone for you to graduate from university with honours. 

In an increasingly globalized world, plagiarism-free research, regardless of its original or translated language sources, can help students achieve success in their studies and careers.
