Medical reasoning by causal simulation
L.-M. Fu · 2003
A rule-based causal simulation system named CAUSIM is described. It offers two kinds of simulation: backward simulation and forward simulation. Backward simulation is used to infer the behavior of specific attributes, whereas forward simulation is taken to arrive at possible overall scenarios. In addition, CAUSIM invokes constraint rules that describe incompatible behavior and values among related variable before applying simulation rules in order to obviate the inconsistencies between the simulation result and existing facts. The advantage of CAUSIM over other approaches lies in the capability of performing both qualitative and quantitative causal simulation in an integrated framework that handles the temporal issue.>
