The world’s most prolific Wikipedia contributor is Malmö University academic

He has published research on a wide range of subjects, but it is best known as the most prolific writer in Wikipedia’s history – with more articles than any other user.

I started writing for Wikipedia around 2007, mainly because it was fun and because knowledge should be shared freely.

Sverker Johansson

“Wikipedia is a way of making research and knowledge accessible to everyone, all over the world,” says Johansson.

The Swedish-language Wikipedia is now the fifth largest language version in the world. Using tools, he has developed himself, Johansson has been able to structure and streamline his writing:

”I started writing for Wikipedia around 2007, mainly because it was fun and because knowledge should be shared freely. A few years later, I came across machine-generated articles of poor quality and thought I could do better. Building my own bot became both a technical challenge and a way to gain more knowledge.”

Since then, Johansson’s bot has created a large number of articles on plant and animal species, as well as on geography – for example, towns, lakes, rivers, and mountains.

“I’m proud that today you can find basic facts about virtually any insect or village on Wikipedia. But I’m also proud that my AI doesn’t just list facts, but can provide more context, such as what the terrain around a place looks like,” he says.

However, Johansson argues that the rapid development of generative AI presents new challenges for Wikipedia, even though AI has long been used as a tool for the site.

“AI-generated answers often appear at the top of search results, which means fewer people click through to Wikipedia. The texts look credible but often contain subtle errors. And because they lack a clear source, they are difficult to verify.” He also points to more long-term consequences:

“As Wikipedia’s visitor numbers decline, it becomes harder to recruit new contributors; this risks leading to a narrower range of voices and perspectives.” Despite this, he does not envisage a future in which humans are replaced by machines. Quite the contrary.

“Human writers will continue to play a central role. Partly as authors of content that AI struggles to handle analyses, context, and controversial topics. And partly as editors who monitor, correct and guide Wikipedia’s growing AI workforce,” adds Johansson.
