Testing Methodology

Evaluation Process

The team used a simple and clear way to test each ai translation detector. They looked at both computer and human checks. The main things they checked were:

• BLEU: This shows how close the translation is to the right answer by matching small parts of text.

• ROUGE: This checks if important details are there by comparing summaries to what people wrote.

• BERTScore: This uses deep learning to see if the meaning is the same, not just the words.

• Precision and recall: These show how well the detector finds ai-made content without making too many mistakes.

• F1 score: This gives a fair result by balancing precision and recall.

• METEOR: This looks at word order and similar words to judge how good the translation is.

• Levenshtein distance: This counts how many changes are needed to make two texts match.

• Perplexity and coherence: These test if the model can guess words and keep the writing logical.

• Human review: Experts checked if the results were fair, true, and safe.

The team tested each detector with short and long texts. They used different languages and both easy and hard topics. They also checked how fast and simple each tool was to use.

Data Sources

The team used many types of data to make the test fair. They used:

• Public translation benchmarks like WMT and IWSLT datasets.

• Real documents from work, school, and publishing.

• Texts sent in by users in many languages.

• Fake texts made by popular ai models.

Being open about how the tests were done helps people trust the results. The team shared their data, how they tested, and any possible problems. This helps users see how the results were made and why they can believe them.

Clear explanations and open data help people see what each ai translation detector can and cannot do. This way follows the best rules and laws for fairness and trust.
