Counter Turing Test ($CT^2$): Investigating AI-Generated Text Detection for Hindi -- Ranking LLMs based on Hindi AI Detectability Index ($ADI_{hi}$)

TL;DR

This paper investigates the detection of AI-generated Hindi text by evaluating multiple LLMs, introducing a new dataset, assessing detection techniques, and proposing a Hindi AI Detectability Index to measure text eloquence.

Contribution

It introduces a Hindi-specific AI detectability index and evaluates multiple detection methods on a new Hindi AI-generated text dataset, advancing multilingual AI detection research.

Findings

26 LLMs evaluated for Hindi text generation proficiency

Five detection techniques tested for Hindi AI text detection

Proposed Hindi AI Detectability Index ($ADI_{hi}$) to measure AI text eloquence

Abstract

The widespread adoption of Large Language Models (LLMs) and awareness around multilingual LLMs have raised concerns regarding the potential risks and repercussions linked to the misapplication of AI-generated text, necessitating increased vigilance. While these models are primarily trained for English, their extensive training on vast datasets covering almost the entire web, equips them with capabilities to perform well in numerous other languages. AI-Generated Text Detection (AGTD) has emerged as a topic that has already received immediate attention in research, with some initial methods having been proposed, soon followed by the emergence of techniques to bypass detection. In this paper, we report our investigation on AGTD for an indic language Hindi. Our major contributions are in four folds: i) examined 26 LLMs to evaluate their proficiency in generating Hindi text, ii) introducing the AI-generated news article in Hindi ($AG_{hi}$) dataset, iii) evaluated the effectiveness of five recently proposed AGTD techniques: ConDA, J-Guard, RADAR, RAIDAR and Intrinsic Dimension Estimation for detecting AI-generated Hindi text, iv) proposed Hindi AI Detectability Index ($ADI_{hi}$) which shows a spectrum to understand the evolving landscape of eloquence of AI-generated text in Hindi.
