This document describes the contents of the directory
|
|
[``GF/examples/mp3`` http://www.cs.chalmers.se/~aarne/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.
|
|
|
|
- how the resource API is used to define concrete syntax
|
|
|
|
- how to divide the grammar into modules
|
|
|
|
|
|
Thus it is not intended to be (even a part of) a really useful
|
|
system.
|
|
|
|
|
|
==Quick try==
|
|
|
|
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 the
|
|
[ATK http://mi.eng.cam.ac.uk/~sjy/software.htm] speech recognition library
|
|
and compiled
|
|
[GF version 14/12/2005 http://www.cs.chalmers.se/Cs/Research/Language-technology/darcs/GF/doc/darcs.html]
|
|
or later, with support for ATK enabled.
|
|
|
|
|
|
==Structure==
|
|
|
|
The directory consists of the following grammars:
|
|
|
|
- [``MP3.gf`` MP3.gf] the main abstract syntax
|
|
- [``MP3I.gf`` MP3I.gf] functor implementation of the main abstract
|
|
- [``MP3Eng.gf`` MP3Eng.gf] English instantiation of the functor
|
|
- [``MP3Fin.gf`` MP3Fin.gf] Finnish instantiation of the functor (buggy)
|
|
- [``MP3Fre.gf`` MP3Fre.gf] French instantiation of the functor
|
|
- [``MP3Ger.gf`` MP3Ger.gf] German instantiation of the functor
|
|
- [``MP3Swe.gf`` MP3Swe.gf] Swedish instantiation of the functor
|
|
- [``Lexicon.gf`` Lexicon.gf] the interface on which ``MP3I.gf`` depends
|
|
- [``LexiconEng.gf`` LexiconEng.gf] English instance of the interface
|
|
- [``LexiconFin.gf`` LexiconFin.gf] Finnish instance of the interface
|
|
- [``LexiconFre.gf`` LexiconFre.gf] French instance of the interface
|
|
- [``LexiconGer.gf`` LexiconGer.gf] German instance of the interface
|
|
- [``LexiconSwe.gf`` 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/
|
|
|
|
|
|
==Resource library version==
|
|
|
|
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.
