2. 1. Expressivity and Complexity of the Grammatical Framework

   Author : Peter Ljunglöf; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grammatical Framework; generalized context-free grammar; multiple context-free grammar; context-free rewriting systems; type theory; expressive power; abstract syntax; linearization; parsing; context-free rewriting systems;

   Abstract : This thesis investigates the expressive power and parsing complexity of the Grammatical Framework (GF), a formalism originally designed for displaying formal propositions and proofs in natural language. This is done by relating GF with two more well-known grammar formalisms; Generalized Context-Free Grammar (GCFG), best seen as a framework for describing various grammar formalisms; and Parallel Multiple Context-Free Grammar (PMCFG), an instance of GCFG.

4. 2. Pure Functional Parsing - an advanced tutorial

   Author : Peter Ljunglöf; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; context-free grammars; parsing algorithms; parser combinators; functional programming;

   Abstract : Parsing is the problem of deciding whether a sequence of tokens is recognized by a given grammar, and in that case returning the grammatical structure of the sequence. This thesis investigates di erent aspects of the parsing problem from the viewpoint of a functional programmer. READ MORE
