AI Prosecutor Gets Better at Handling Crime

  A robot judge may sound like a character from a science fiction novel, but it has in fact become a reality. A research team in China recently developed an Artificial Intelligent prosecutor (AIP) that can judge whether a person is guilty with more than 97 percent accuracy.

  The Shanghai Pudong People's Procuratorate tested the AIP, which can only pass judgment that is based on a verbal description of the case. Theoretically, it can reduce human workload and costs, while allowing prosecutors to focus on more complex tasks.

  "The AIP system can replace prosecutors in the decision -making process to a certain extent," Shi Yong, the research team leader, wrote in an article.

  This is not the first time that AI has been used in law enforcement. As early as 2016, China's procurators began to use AI. Nowadays, many of them still use a kind of AI tool named System 206, which can assess the strength of proof, the conditions for arrest and the danger of suspects to the public.

  The AIP can run on a computer. It can make a judgment based on 1,000 features retrieved from human case descriptions for each suspect. Most of these features are too small or not detailed enough, requiring System 206 to evaluate evidence.

  It is reported that from 2015 to 2020, the machine has been tested on more than 17,000 cases, and so far, it has been able to identify and prosecute the eight most common crimes, such as credit card fraud and gambling in Shanghai.

  Shi explained that the AIP would soon become more effective through upgrades, and in the future, it will be able to identify less common crimes and bring multiple charges against a single suspect.

  However, no matter how good it is, there is always the possibility of error. AIP cannot foresee how the public will react to cases in a changing social environment. "AI may help spot mistakes, but it cannot replace human decision-making," said Shi.
