Graph Structured Stack

A general device for handling nondeterminism in stack operations is described. The device, called a Graph-structured Stack, can eliminate duplication of operations throughout the nondeterministic processes. This paper then applies …...

We apply the graph-structured stack (GSS) to shift-reduce parsing in a Combinatory Cate- gorial Grammar (CCG) parser. This allows the shift-reduce parser to explore all possible parses in polynomial time …...
