Using Uncertain Time Intervals in Linked Data
Tatsuki Sekino · International Journal of Geoinformatics · 2019
Uncertain temporal data often included in a dataset are critical, especially in history and archeology. In this study, we proposed a method to represent uncertain time intervals in uncertain temporal data and examine the relationships between them using the Linked Data technology. We created uncertain time intervals by specifying the ranges for the beginning and the ending points, and its features were represented by possible and reliable time intervals. Moreover, we divided the states of relationships between the two uncertain time intervals as reliable, possible, and impossible relations for each Allen’s relation. Using a sample model, we demonstrated that procedures for creating uncertain time intervals and examining the relationships between them can be realized as RDFs in the Linked Data world.
