> 中文摘要: 本文提出了使用选择函数的亚蕴涵询问求值方法以及依据此方法建立的询问求值算法IVAL.这种方法比Bossu和Siegal的算法VAL简便,效率高.IVAL和VAL同时在SUN-4上用C-Prolog语言实现.本文给出了IVAL的理论依据,并把两种算法的执行效果作了比较.

Abstract:A method for query evaluation for sub implication using selection function is presented. An algorithm IVAL is developed based on the method. IVAL is more simple and efficient than the algorithm VAL presented by Bossu and Siegel. Both VAL and IVAL are implemented on SUN 4 in C Prolog, and the efficiency of the two algorithms is compared.
