TOKYO, June 14 — An artificial intelligence startup has developed a system that analyses academic papers to determine whether they were written by humans or generated by AI, with hopes of wider adoption by academic institutions, Kyodo News reported.

Developed by Valar Intelligence, an Osaka-based startup, the identification system, “Puddin AI”, requires users to write and submit their papers on its platform.

Kyushu University has been trialling the system in classes, while several dozen universities are considering adopting it, according to the company.

The system focuses on the writing process, recording when a user begins writing, their writing speed and the chronological order of revisions.

When the identification button is pressed, it assesses the “humanness” of a piece of writing using around 200 indicators, including common human spelling mistakes, pauses between writing sessions and the estimated amount of time typically required to produce the work.

Copying and pasting an AI-generated composition drastically shortens the writing process, allowing the system to determine that a particular piece was not written by a human.

The results are divided into three categories: AI, AI-supported and Human.

According to the developer, the system supports Japanese, English and four other languages, and can analyse university assignments, academic papers and corporate documents.

“I want students to take their time and write their work on their own. This system can verify originality, making fair evaluation possible,” said Andrew John Chapman, an associate professor of energy economics at Kyushu University. — Bernama-Kyodo
