In recent years, artificial intelligence has gradually affected all walks of life. The University of Hong Kong has developed "artificial intelligence lawyers", which combines knowledge in the legal field and machine learning technology, and uses artificial intelligence technology to assist in estimating the sentencing of drug trafficking crimes.

The program only needs to answer four simple questions to estimate the term of imprisonment.

According to the team, the program has studied more than 3,000 judgments and found an accuracy rate of at least 91% through computer model testing; the second phase will consider extending it to personal injury estimation.

The team hopes that the program can help professionals including lawyers, social workers and teachers.

The representative of the Hong Kong Federation of Youth Groups pointed out that in the past, to assist people involved in crimes, social workers had to read newspapers to estimate the sentence. Now it can be used as an additional reference tool. It can also be used for educational purposes.

Program to study more than 3,000 verdicts to learn from judges’ sentencing guidelines

The research team of the Law and Technology Research Center of the University of Hong Kong has developed the first-stage model of the "Artificial Intelligence Lawyer of the University of Hong Kong" within one and a half years to estimate the relevant information in Article 4(1)(a) of the Dangerous Drugs Ordinance, Chapter 134 of Hong Kong Law Sentencing for the crime of trafficking in dangerous drugs.

Gao Zhiming, co-director of the Research Center and a professor of the Department of Computer Science at the University of Hong Kong, said that the program studies more than 3,000 judgments as of 2019 and learns the legal principles and sentencing guidelines followed by judges in general judgments.

The program is divided into web and mobile versions. Users only need to answer the type and weight of drugs involved; and additional or commutation factors, such as whether they are involved in cross-border drug trafficking, whether they have assisted the police in arrest operations, whether they have been guilty, etc., to display the estimated sentence .

The program can also provide links to court cases most closely related to the user's case for the reference of lawyers and others.

Zhang Shanyu, co-director of the research center and a professor at the Hong Kong University School of Law, said that he is now applying for funding for the second-stage model, hoping to cover the estimation of personal injuries.

Chen Wenhao, deputy director-general of the Hong Kong Federation of Youth Groups, pointed out that in the past, to assist people involved in related cases, they had to rely on social workers to read newspapers and check past case estimates. They would also seek the advice of volunteer lawyers. However, "Parents of young arrested persons will be worried and want to know Punishment for Baa."

After the program is in place, an additional tool can be provided to provide more information to the arrested person.

In addition, Chen believes that the program can also be used in educational work, including anti-drug seminars and workshops, so that young people can understand the legal consequences of committing drug trafficking crimes.

I was asked why the program does not provide an estimate of the range of the sentence, but an accurate figure?

Zhang Daming, the chief lecturer of the Law School of the University of Hong Kong, responded that the two "have their own advantages." Even if the range of sentencing is estimated, it is difficult to ensure that the final judgment does not exceed the estimated range.

He emphasized that the relevant procedures cannot replace legal opinions of lawyers and judgments of judges.
