How to know if an online discussion is going to get nasty

Researchers have created a model to predict which civil online conversations might take a turn and derail.

After analyzing hundreds of exchanges between Wikipedia editors, the researchers developed a computer program that scans for warning signs in participants’ language at the start of a conversation—such as repeated, direct questioning or use of the word “you”—to predict which initially civil conversations would go awry.

Early exchanges that included greetings, expressions of gratitude, hedges such as “it seems,” and the words “I” and “we” were more likely to remain civil, the study found.

“There are millions of such discussions taking place every day, and you can’t possibly monitor all of them live. A system based on this finding might help human moderators better direct their attention,” says Cristian Danescu-Niculescu-Mizil, assistant professor of information science at Cornell University and coauthor of the paper.

“We, as humans, have an intuition of whether a conversation is about to go awry, but it’s often just a suspicion. We can’t do it 100 percent of the time. We wonder if we can build systems to replicate or even go beyond this intuition,” Danescu-Niculescu-Mizil says.

The computer model, which also considered Google’s Perspective, a machine-learning tool for evaluating “toxicity,” was correct around 65 percent of the time. Humans guessed correctly 72 percent of the time.

People can test their own ability to guess which conversations will derail at an online quiz.

The study analyzed 1,270 conversations that began civilly but degenerated into personal attacks, culled from 50 million conversations across 16 million Wikipedia “talk” pages, where editors discuss articles or other issues. They examined exchanges in pairs, comparing each conversation that ended badly with one that succeeded on the same topic, so the results weren’t skewed by sensitive subject matter such as politics.

To stop racist comments, call them out

The researchers hope this model can be used to rescue at-risk conversations and improve online dialogue, rather than for banning specific users or censoring certain topics. Some online posters, such as nonnative English speakers, may not realize they could be perceived as aggressive, and nudges from such a system could help them self-adjust.

“If I have tools that find personal attacks, it’s already too late, because the attack has already happened and people have already seen it,” says coauthor Jonathan P. Chang, a PhD student at Cornell. “But if you understand this conversation is going in a bad direction and take action then, that might make the place a little more welcoming.”

The paper, co-written with additional collaborators at Jigsaw and the Wikimedia Foundation, will be part of the Association for Computational Linguistics’ annual meeting next week in Melbourne, Australia.
