A single bot generated and published millions of articles on the largest non-English version of Wikipedia. The results caused a rift among editors — and a glimpse of what the online encyclopedia might face from AI.

With nearly 7 million articles, the English-language edition of Wikipedia is by many measures the largest encyclopedia in the world.

The second-largest edition of Wikipedia boasts just over 6 million articles. It isn’t French, or Spanish, or Chinese Wikipedia.

It’s Cebuano: a language spoken mostly in the southern Philippines.

But Cebuano Wikipedia didn’t grow with the help of thousands of volunteer editors, as its English counterpart did. Most of the articles come from one person: Swedish linguist Sverker Johansson.

Dr Johansson designed a program, dubbed “lsjbot”, which generated millions of articles in several languages, but particularly Cebuano.

It also laid bare a debate which Wikipedia has been grappling with since its inception, and which artificial intelligence (AI) is making ever more pressing.
