Differentiating Between Human-Written and AI-Generated Texts Using Automatically Extracted Linguistic Features

Understand

While extensive research has focused on ChatGPT in recent years, very few studies have systematically quantified and compared linguistic features between human-written and artificial intelligence (AI)-generated language.

• This exploratory study aims to investigate how various linguistic components are represented in both types of texts, assessing the ability of AI to emulate human writing.
• Using human-authored essays as a benchmark, we prompted ChatGPT to generate essays of equivalent length.
• These texts were analyzed using Open Brain AI, an online computational tool, to extract measures of phonological, morphological, syntactic, and lexical constituents.
