【摘要】：为解决不确定性语义时态查询及其计算资源配置的优化问题,使用子结构逻辑对时态演算机制进行了完善并构建了查询中间件原型.基于构造性逻辑语义,构建了中间件演算流程,将时态属性映射为类型语义,使针对时间属性的运算从句法演算中剥离,在保证表达能力的前提下,仅进行语义计算,加速并优化了查询演算流程.实验结果表明:该方法与中间件原型可行、高效,具有共性,为时态信息处理提供理论与技术支撑.
[Abstract]:In order to solve the optimization problem of uncertain semantic temporal query and its computing resource allocation, the temporal calculus mechanism is improved by using substructure logic and a query middleware prototype is constructed. Based on the structural logic semantics, the middleware calculus flow is constructed, and the temporal attribute is mapped to type semantics, so that the operation of temporal attribute is separated from the syntactic calculus, and only the semantic calculation is carried out under the premise of ensuring the expression ability. The query calculus flow is accelerated and optimized. The experimental results show that the method is feasible, efficient and common with middleware prototype, and provides theoretical and technical support for temporal information processing.
