Abstract

About the relation of indeterminacy temporal data in temporal database, Snodgrass brought forward probability method to solve the problem by defining the “Before” relation of indeterminacy instant. Based on which, the paper extends its method by adding two new temporal definitions of indeterminacy instant as well as indeterminacy intervals: “BeforeI” and “simultaneity”. By introducing an argument called “Fuzziness” to describe the degree of indeterminacy, a temporal DBMS based on Computer-based Patient Records (CPR) is constructed to implement the mining of indeterminacy medical temporal data.
