An embedded pushdown automaton or EPDA is a computational model for parsing languages generated by tree-adjoining grammars (TAGs). It is similar to the context-free grammar-parsing pushdown automaton, except that instead of using a plain stack to store symbols, it has a stack of iterated stacks that store symbols, giving TAGs a generative capacity between context-free grammars and context-sensitive grammars, or a subset of the mildly context-sensitive grammars.

dbpedia-owl:abstract
  • An embedded pushdown automaton or EPDA is a computational model for parsing languages generated by tree-adjoining grammars (TAGs). It is similar to the context-free grammar-parsing pushdown automaton, except that instead of using a plain stack to store symbols, it has a stack of iterated stacks that store symbols, giving TAGs a generative capacity between context-free grammars and context-sensitive grammars, or a subset of the mildly context-sensitive grammars.
  • 嵌入下推自动机或 EPDA 是分析树-邻接文法(TAG)的计算模型。除了不再使用堆栈来存储符号之外,它类似于分析上下文无关文法的下推自动机。它有存储符号的重复堆栈组成的一个栈,这给予了 TAG 在上下文无关文法和上下文有关文法之间的复杂度,或者说是适度上下文有关文法的子集。
