基于故事分析文法的故事理解法是本文作者在其博士论文中提出的一种面向故事深层含义的对语法、语义和语用综合进行理解的形式化方法，故事分析文法是一种高维的上下文有关文法，为了提高它的描述能力和表达范围，本文定义了一种特殊的产生式：无序产生式，并将它引入故事分析文法，讨论了由此带来的对故事分析文法的影响和无序产生式在故事分析文法中的性质，最后给出了含无序产生式的故事分析文法的一个子类文法的语法分析算法．

Story Parsing Grammar(abbr. SPG)based story understanding approach,proposed by the author, is a formal method orienting the deep level meaning of the story to understand the syntax, semantics and pragmatics of the story. SPG is highdimensional and context - sensitive. In order to strengthen SPG s descriptive ability and widen SPG s representative scope, a special kind of production, called unordered production, is defined and introduced into SPG. Concequentially, influences of unordered production on SPG are discussed.Moreover the charateristics of the unordered production in SPG are discussd.The syntactic parsing algorithm of a subclass of SPG with unordered productions is given at last.
