Abstract:This paper has the goals (1) of unifying top-down parsing with shift-reduce parsing to yield a single simple and consistent framework, and (2) of producing provably correct parsing methods, deterministic as well as tabular ones, for extended context-free grammars (EBNF ) represented as state-transition networks. Departing from the traditional way of presenting as independent algorithms the deterministic bottom-up LR (1), the top-down LL (1) and the general tabular (Earley) parsers, we unify them in a coherent … Show more
