The key to obtaining case justice lies in value judgment

and value judgment relates to the subject's emotion and experience

thus becoming a common field of intuition and prejudice. On the one hand

big data analysis technology provides sufficient information and "data experience" for judges depending on analysis of the correlation between massive data on the Internet

so that judges can have a more objective and accurate understanding of the case

thus helping to reduce the influence of intuition and prejudice on value judgment; On the other hand

the judicial aid systems provide a test and reflection tool for judges' decision-making

making the judge's self-decision arguments an argument for the other

which also helps to exclude the judge's intuition and prejudice. However

due to the contextualized bottleneck of representation

the lack of authenticity and integrity of the data and the black box of the algorithm

artificial intelligence has also been limited in its ability to obtain the above-mentioned functions of case justice.
