Abstract: Target action information is an important component of intelligence data.A key criterion for the reliability of its action information is whether the target actions are spatio-temporally consistent.By formally defining a target action information repository as the detection object and a target action spatio-temporal knowledge base as the detection basis,a modeling method for the problem of spatio-temporal consistency detection of target actions is proposed.Based on this,the spatio-temporal consistency detection problem for target actions is defined,and a metric system for measuring spatio-temporal consistency is established.Finally,an algorithm for detecting the spatio-temporal consistency of target actions is designed using Answer Set Programming (ASP).The experimental results of quality detection for typical military target activity information indicate that the research findings have practical reference value.
