UnverifiedImplementation methods for robustness testing include synonym substitution, sentence structure paraphrasing, addition or deletion of details, and linguistic style transformation.76% similarUnverifiedThe tokenization strategy directly determines the granularity of vocabulary validation: too coarse a split will miss fabricated content, while too fine a split will misjudge fragments with no real meaning as semantic words and cause false positives; synonyms, morphological variations and cross-language mixing affect matching, and non-English scenarios require specially designed tokenization and morphological normalization schemes.73% similarUnverifiedPrompt perturbation refers to making minor paraphrases of the original question (such as adjusting wording, changing sentence structure, or substituting synonyms) while keeping the semantics essentially unchanged.70% similarUnverifiedSome wording changes are unrelated to facts, for example changing 'fabricated' to 'started' or 'the best ammunition against something' to 'standard reference'; no check can flag such problems, and a human must read them.69% similarUnverifiedApplying synonym substitution or sentence restructuring to text significantly alters the perplexity distribution, causing perplexity-based detection to fail.69% similar
