摘要
解题策略能表明应用题中的数量关系,策略分解和表示是小学算术应用题自动解题系统中十分关键的一步。共提炼197条解题策略,将其分为三个层次,且提出策略生长图表明其层次关系,选择框架知识表示方法表示策略,以构建解题策略知识库,供自动解题程序调用。
The de-composability and representation of Problem-solving strategy that can show the quantitative relationship of word problems is a key part in Auto-Solving system of primary school mathematic word problems. The paper is divided into three levels of the problem-solving strategies and put forward strategy growth map indicating their level of relationship. There are 197 strategies that can be used for automatic computer problem-solving. At last, the thesis chooses the framework for knowledge representation to represent each strategy, so as to construct knowledge base for being called by auto-solving programs.
