The difficulty of "subjective" identification and lack of evidence have plagued the judicial circle for a long time. It is the focus of finding out the truth, and it is also the difficulty in finding out the truth. Many difficult cases, unjust, false, and wrong cases were caused by their vagueness. For this reason, a method and means to solve the "subjective" problem is urgently needed. Situation appraisal, as a special kind of appraisal in Japan, focuses on the subjective elements of the parties and is an effective way to solve the "subjective" problem. However, this identification method has many problems in current practice and cannot be promoted. At the time when the socialist system with Chinese characteristics and artificial intelligence technology are booming, situation identification is expected to take root and sprout under the soil of China combined with artificial intelligence technology to better solve "subjective" identification, evidence issues and other issues.
