This document describes the contents of the directory
GF/examples/mp3
.
This directory contains a small example of a dialogue system grammar built by using the GF resource grammar library. Its sole purpose is to demonstrate this usage, i.e.
Thus it is not intended to be (even a part of) a really useful system.
To try out the grammar, do for example
gf mk3.gfcm -- start GF > gr | l -multi -- random generate > p -tr "which song is played ?" | l -multi -- parse and translate > gt -tr | l -lang=MP3Swe -- generate Swedish "treebank" > si -tr | p | l -multi -- translate speech input [say:] I want to play Yesterday
The last command only works if you have installed ATK and compiled GF version 14/12/2005 or later.
The directory consists of the following grammars:
MP3.gf
the main abstract syntax
MP3I.gf
functor implementation of the main abstract
MP3Eng.gf
English instantiation of the functor
MP3Fin.gf
Finnish instantiation of the functor (buggy)
MP3Fre.gf
French instantiation of the functor
MP3Ger.gf
German instantiation of the functor
MP3Swe.gf
Swedish instantiation of the functor
Lexicon.gf
the interface on which MP3I.gf
depends
LexiconEng.gf
English instance of the interface
LexiconFin.gf
Finnish instance of the interface
LexiconFre.gf
French instance of the interface
LexiconGer.gf
German instance of the interface
LexiconSwe.gf
Swedish instance of the interface
The main linguistic content is in the functor MP3I
and the
instances of the Lexicon
interface.
The way in which the implementation is divided to a functor and an interface depending on it should work as a model for building resource grammar applications in general.
In order to compile the grammars from source, you must set the
environment variable GF_LIB_PATH
to point at the root
of your GF library, e.g. in the bash shell,
export GF_LIB_PATH=/usr/local/lib/GF/
The example builds on resource v. 0.6. The reason for not building on a later version is that German is not yet implemented for them. The example will probably be migrated to v. 1.0 soon. The new resource version will fix the bugs in the Finnish implementation.
