Re: Bison's semantic parsers

[Hans Aberg]

I made an Internet-search on "semantic parser", and I got the following:

-- Asks in 1992 what the semantic parser & guards feature of Bison is;
apparently no reply: http://compilers.iecc.com/comparch/article/92-09-202

-- A Spoken Natural Language Interface to the Intelligent Wheelchair:
http://www.cs.utexas.edu/users/speech/slides/index.htm
Apparently, semantic parsing here has something to do with extracting
semantic contextual information from the human spoken language.

-- |E| Semantic Parser: http://www.imagination-engines.com/text/semfs.htm
Also tries to extract semantic contextual information from the human spoken
language.

Perhaps the semantic parser in Bison has something to do with changing
parsing based on semantic contextual information. It would then perhaps be
an experiment with implementing attribute grammars, and other such context
dependent grammars. -- Just a wild guess. At least, this would explain why
it is "hairy". :-)
