• What is parsing in program languages?

  Parsing in program languages is based on the theory ofcontext-free languages. Context-freelanguages were invented in an attempt to describe natural languages mathematically, and Copyrightcby David L. Dill, 1998{2015. All rights reserved.

• Can a formal notation be used to generate a parser?

  However,once a formal notation became available, the possibility of using it to generate a parserautomatically became irresistible. Parsing theory is one of the major triumphs of computer science. It draws on a deep andindependently interesting body of theory to solve important practical problems.

• How do LR parsing algorithms work?

  As with LL(1) parsing, all LR parsing algorithms require that the tableuniquelydeterminethe next parse action: there must be at most one action in each entry of the parse table,or the CFG cannot be handled by the parsing algorithm, in which case the CFG is said tobe \ ot SLR(1)" (or LR(1) or LALR(1)).

• What is a parse table in CFG?

  The parse table consistsof two two-dimensional arrays: anACTIONtable and aGOTOtable. Here is the SLR(1)parse table for the CFG above. The rows of both tables are indexed by the states of the LR(0) machine. The columns of theACTIONtable are indexed by terminal symbols and the end-of-le marker $.

  You can choose any name for the file, but we suggest adding a suffix to the name of the main file. For our example we use the file name document_chapter1.tex. First, copy template_chapter.tex to document_chapter1.tex and add the line \include{document_chapter1}

  We need to have C and C++ compilers! Questions for Today How do you go about parsing ambiguous grammars efficiently? How do you produce all possible parse trees? What else can we do with a general parser? The Earley Parser Motivation: The Limits of LR LR parsers use shift and reduce actions to reduce the input to the start symbol.

  Parsing is the process of identifying this kind of structure for a sentence. It is one of the best-understood areas of computational linguistics. Arguably the best. The literature is very large, and, at least if you are parsing news-paper articles, several good parsers are downloadable from the web.

  Parsing algorithm • An adaptation of the CYK chart parsing algorithm (A nice example of dynamic programming) • Rewrite the grammar so that all rules are binary (or unary) • Consider every span of tokens in input, bottom-up • Consider all ways of splitting span into two sub-spans • Consider all grammar rules whose RHSes match the sub-spans

  Parsing theory has been so successful that it is taken for granted. For practical purposes, the problem is (almost) completely solved. 2.1 Context-free grammars A context-free grammar (also called BNF for \Backus-Naur form") is a recursive de nition of the structure of a context-free language.
