Center hyperedge (induced by source paper "on the computational models for the analysis of illicit activities"):
  Abstract: This paper presents a study on the advancement of computational models for the analysis of illicit activities. Computational models are being adapted to address a number of social problems since the development of computers. Computational model are divided into three categories and discussed that how computational models can help in analyzing the illicit activities. The present study sheds a new light on the area of research that will aid to researchers in the field as well as the law and enforcement agencies.
