Efficient Tabular LR Parsing [PDF]

open access: yes, 1996
We give a new treatment of tabular LR parsing, which is an alternative to Tomita's generalized LR algorithm. The advantage is twofold. Firstly, our treatment is conceptually more attractive because it uses simpler concepts, such as grammar ...

Practical LR Parser Generation

open access: yesCoRR, 2022
Parsing is a fundamental building block in modern compilers, and for industrial programming languages, it is a surprisingly involved task. There are known approaches to generate parsers automatically, but the prevailing consensus is that automatic parser generation is not practical for real programming languages: LR/LALR parsers are considered to be ...

Optimization of LR(k) parsers

open access: yesJournal of Computer and System Sciences, 1972
Certain techniques for modifying LR(k) parsing tables to decrease their size have been developed by Korenjak [2] and DeRemer [3, 4]. We show that the techniques of the latter can be characterized by two transformations on sets of tables. We then show that the “simple” LR(1) method of DeRemer [4] can be considered a special case of Korenjak's method [2].

LR parsers for natural languages [PDF]

open access: yesProceedings of the 22nd annual meeting on Association for Computational Linguistics -, 1984
MLR, an extended LR parser, is introduced, and its application to natural language parsing is discussed. An LR parser is a shift-reduce parser which is deterministically guided by a parsing table. A parsing table can be obtained automatically from a context-free phrase structure grammar.

Cover results and normal forms [PDF]

open access: yes, 1977
The purpose of this paper was to sketch an area of problems for the concept of cover. We showed that in spite of some remarks in the literature the problem of covering (unambiguous and -free) cfg's with cfg's in GNF is open.

Incremental Parser Generation for Tree Adjoining Grammars

open access: yes, 1998
This paper describes the incremental generation of parse tables for the LR-type parsing of Tree Adjoining Languages (TALs). The algorithm presented handles modifications to the input grammar by updating the parser generated so far.

Research on Architectures for Integrated Speech/Language Systems in Verbmobil [PDF]

open access: yes, 1996
The German joint research project Verbmobil (VM) aims at the development of a speech to speech translation system. This paper reports on research done in our group which belongs to Verbmobil's subproject on system architectures (TP15).

GLR-Parsing of Word Lattices Using a Beam Search Method [PDF]

open access: yes, 1995
This paper presents an approach that allows the efficient integration of speech recognition and language understanding using Tomita's generalized LR-parsing algorithm. For this purpose the GLRP-algorithm is revised so that an agenda mechanism can be used

On the Relation between Context-Free Grammars and Parsing Expression Grammars [PDF]

open access: yes, 2014
Context-Free Grammars (CFGs) and Parsing Expression Grammars (PEGs) have several similarities and a few differences in both their syntax and semantics, but they are usually presented through formalisms that hinder a proper comparison.

Towards Efficient, Typed LR Parsers

open access: yesElectronic Notes in Theoretical Computer Science, 2006
AbstractThe LR parser generators that are bundled with many functional programming language implementations produce code that is untyped, needlessly inefficient, or both. We show that, using generalized algebraic data types, it is possible to produce parsers that are well-typed (so they cannot unexpectedly crash or fail) and nevertheless efficient ...
