在对已知案件和犯罪嫌疑人建模的基础上,结合社会网络方法对犯罪组织进行建模,并根据犯罪组织密度来判断该组织活动的频繁性,以及根据犯罪嫌疑人的危害程度、犯罪组织中心度等指标来建立犯罪组织层次树,推断犯罪组织的重要人员以及组织成员间的层次关系。实验结果显示,基于社会网络的犯罪组织层次树模型具有较好的实用性。 Based on the modeling of known cases and suspects, the criminal organization is modeled in combination with the social network method. The frequency of the organization’s activity is judged according to the density of the criminal organization, and the crime is committed according to the degree of harm of the criminal suspect The center of organization and other indicators to establish a hierarchy of criminal organizations, inference of criminal organizations, key personnel and organizational members of the hierarchical relationship. Experimental results show that the social network-based criminal organization level tree model has good practicality.
