Burstiness
A metric that measures the degree of variation in sentence complexity within a text. Human writing typically exhibits pronounced burstiness, alternating between complex and simple sentences, while AI-generated text tends to be relatively uniform. It is often used in combination with perplexity for AI content detection.
Core Facts
Mainstream AI detection tools primarily rely on two statistical metrics—Perplexity and Burstiness—to distinguish human writing from AI-generated text.
AI detection tools such as Weipu, Gezida, GPTZero, and Turnitin AI Detection primarily detect content based on two metrics: text Perplexity and Burstiness.
Burstiness refers to the degree of fluctuation caused by alternating complex and simple sentences in text; human writing typically exhibits more pronounced burstiness, while AI-generated text is relatively smooth and uniform.
Timeline (last 90 days)
Burstiness describes the degree of fluctuation in sentence length and complexity; AI output tends to maintain uniform sentence lengths, resulting in low burstiness.
