A Stack Implementation of A Shift-Reduce Parser There are four possible actions of a shift-parser action: Shift : The next input symbol is shifted onto the top of the stack. Reduce: Replace the handle on the top
In this paper, we present a probabilistic shift-reduce parsing model which can overcome low context-sensitivity of previous LR parsing models. Since previous models are restricted by LR parsing framework, they can utilize only a lookahead and a LR state (stack). The proposed model is not ...
