Abstract(in English) In the temporal interval algebra, we classify the time intervals into real and null ones. We define composite intervals which consists of real and null ones. In this paper, we introduce the definition of the binary temporal relations between composite intervals in order to extend the algebra and show its algebraic features. The extention can handle the constraint, relationship between not, only real intervals, but also null ones. Accordingly, we can lucidly describe complex constraints in the real world. Under constraints, invalid inquiries can be rejected at the stage of its preprocessings, and the operations of the temporal interval algebra call be efficiently executed.
