EXTENDED METHOD FOR CONSTRUCTING INTELLIGENT SYSTEM PROCESSING UNCERTAIN CAUSAL RELATIONSHIP TYPE INFORMATION

摘要

A computer readable storage medium. A computer program is stored on the storage medium; when the computer program is executed, a method for an intelligent system processing uncertain causal relationship type information can be executed. Regarding the method, the following technical content is added on the basis of existing dynamic uncertain causality graph technology: expressing, by using a new logic gate and new action variables, an effect of evidences and a combination thereof on the probability of occurrence of a root cause event; expressing, by using an inverse logic gate, a logic relationship between a cause event and a combination of more than one result event, and performing reasoning; expressing, by using a specific event, a corresponding relationship between the specific event and a root cause event, and directly determining a cause when the specific event is observed; expressing, by using a degree of attention of a result event, a degree of decrease of a probability that a reasoning result is true due to that the result event cannot be explained by the reasoning result, and involving said degree of attention in probability calculation; and expressing, by using a degree of risk of the root cause event, a degree of damage to a system caused by the root cause event, and involving said degree of risk in reasoning calculation.
