Design and Application of Criminal Investigation DSS Based on Case Reasoning

Expert knowledge in the criminal investigation area is mostly empirical and tacit, which brings great difficulties to construct criminal investigation decision support system (CIDSS). Case-based reasoning (CBR) is a kind of incremental learning method that records successful-solved cases with their experiences to effectively overcome the bottleneck of knowledge acquisition and be helpful to solve similar crime problems. From the actual demands of police force, author designs a framework of CIDSS based on case reasoning, and discusses its function, process, and technical points, so as to provide a feasible tool for criminal investigation, crisis intervention and early warning.
