When Chinese reconnaissance balloons flew over the United States and Canada last year, tens of thousands of bots competed to shape the discussion on Twitter, according to an analysis of social media posts.
Kathleen Curley and Lynette Hui Xiang Ng A research team from Carnegie Mellon University in Pennsylvania tracked approximately 1.2 million tweets posted by more than 120,000 users on Twitter (later renamed to X) between January 31, 2023 and February 22, 2023. did. All tweets included the hashtags #chineseballoon and #weatherballoon and discussed the controversial airborne. The US claimed that China used it for espionage.
Tweets were then located using Twitter's location feature and checked with an algorithm called . bot hunterlook for signs that the account is not managed by a human.
“There are many things going on. [identifying a bot] Examples are whether messages are being sent so fast that a human could literally not type them that fast, or if someone is geotagged for one minute in London, but in New Zealand a person can physically type For example, if it is not possible. Please do that,” says Carly.
Researchers found that about 35 percent of geotagged users in the U.S. exhibited bot-like behavior, while 65 percent appeared to be human. In China, the proportions were reversed, with 64 percent bots and 36 percent humans.
Of the accounts claiming to be from neither country, 42 percent were bots and 58 percent were human. Although reliable numbers are difficult to come by, previous research suggests that 10-20% of Twitter users are bots. The bot autonomously performs tasks such as sending her Twitter messages to users on the platform and “liking” other posts.often used to try influence public opinion.
“We're seeing more bot activity in tweets that appear to be coming from Chinese communities than we are seeing coming from American communities,” Curley said. The overall rate of bot accounts was also higher during the Chinese spy balloon debate than at other events, researchers said.
As an example, a bot based in China posted: “#USA #China #February 14th” […] Some may speculate that the US is using the #China spyballoon “excuse” to escalate tensions with #Beijing. Remember, US airspace is highly controlled and we have more accurate satellite technology for spying. ”
Neither Carley nor Ng would speculate on who might be behind the bot. stephen buckley Researchers at City University of London said: “There is likely to be a mix of state and individual actors seeking to sway and manipulate public opinion regarding breaking news.”
As for whether bot activity has made a difference, Curley said: “The fact that bots speak a little differently to humans means what people were reading will look a little different and future conversations will look different.” Buckley says it's important to be “very wary” of content you post and assume it wasn't posted by a human.
