The Temporal Querying of Uncertain Semantics via Substructural Logic

TENG Shaohua;TU Hongjun;LIU Dongning;School of Computer Science and Technology,Guangdong University of Technology;  
Temporal querying of uncertainty semantics is an important and open problem. Its optimization in computing resource allocation is critical with respect to temporal data processing. A temporal calculating system via substructural logic has been put forward. It can deal with uncertain semantics thoroughly. Based on these,a querying middleware prototype has been constructed. It maps time attributes to types directly. Therefore,operations of time attributes can be divorced from syntax calculation,but still ensure knowledge represented. That is lead to the querying concisely and efficiently. Experimental results show that the method and middleware prototype are feasible and valid. And it contributes to provide system method to support temporal database,especially to temporal querying of uncertain semantics.
