Dialogue system grammars using GF resource.
|
|
|
|
AR 16/5/2006
|
|
|
|
|
|
24/5 Added multimodality.
|
|
|
|
==Functionality and purpose==
|
|
|
|
Dialogue system abstract syntax + concrete syntaxes for
|
|
different languages. One of them is Prolog (with some resemblance to
|
|
dialogue moves in GoDiS).
|
|
|
|
The purpose is to show how new systems can be built for new domains just
|
|
by specifying just two things:
|
|
- a domain ontology in abstract syntax
|
|
- a domain terminologies in concrete syntaxes
|
|
|
|
|
|
This is based on two library elements
|
|
- base dialogue grammars
|
|
- resource grammar libraries
|
|
|
|
|
|
In general, the only kind of elements that need to be added are
|
|
constants (0-place fun's) of the following categories from Dialogue.gf.
|
|
```
|
|
Kind ; -- e.g. Room
|
|
Object Kind ; -- e.g. Kitchen
|
|
Oper0 ; -- e.g. Stop
|
|
Oper1 Kind ; -- e.g. Play
|
|
Oper2 Kind Kind ; -- e.g. Add
|
|
Move ; -- e.g. MorningMode
|
|
```
|
|
|
|
|
|
==Files in this directory==
|
|
|
|
Files (for X = Eng, Fin, Fre, Prolog, Swe):
|
|
|
|
Files provided as library to build on:
|
|
```
|
|
Dialogue.gf -- base dialogue grammar
|
|
DialogueX.gf -- implementation instance
|
|
DialogueI.gf -- implementation functor
|
|
|
|
ResProlog.gf -- help constructs for Prolog terms
|
|
|
|
Weekday.gf -- untility grammar with weekdays
|
|
WeekdayX.gf
|
|
|
|
AuxDialogue.gf-- interface of auxiliary resource-defined opers
|
|
AuxX.gf -- instances for different languages
|
|
```
|
|
Files implementing two examples.
|
|
```
|
|
Agenda.gf -- application grammar for agenda
|
|
AgendaX.gf
|
|
|
|
Lights.gf -- application grammar for lights
|
|
Lights.gf
|
|
```
|
|
|
|
==Files needed to build a new application==
|
|
|
|
To build a new application for domain Dom, you thus need
|
|
```
|
|
Dom.gf -- introduce fun's in Kind, Object, Oper0, Oper1, Oper2
|
|
DomX.gf -- concrete syntax of the new fun's for language X
|
|
```
|
|
|
|
==Some tests==
|
|
|
|
You first need to do, with the latest resource grammar version,
|
|
- ``make present`` in ``lib/resource-1.0``
|
|
|
|
To test an application in GF, do e.g.
|
|
- ``make lights`` to make a package with all the Lights grammars
|
|
- ``make engcorpus`` to generate an English corpus
|
|
- ``make swecorpus`` to generate a Swedish corpus
|
|
|
|
|
|
|
|
Here are some other commands:
|
|
- ``i LightsEng.gf`` in current dir, to load a grammar
|
|
- ``gr | l -all`` to random-generate
|
|
- ``gt -depth=4 | pt -transform=typecheck | l -all`` to generate a corpus
|
|
- ``p "switch off all lights in the kitchen"`` to parse
|
|
- ``i LightsProlog.gf`` to load the Prolog version
|
|
- ``pg -printer=gsl -startcat=Move`` to print a Nuance grammar
|
|
- ``p -lang=LightsEng "switch off all lights" | pt -transform=solve | l -lang=LightsProlog``
|
|
to translate from English to Prolog
|
|
- ``si -tr -lang=LightsEng | p -cat=Move -lang=LightsEng | pt -transform=solve | l -lang=LightsProlog``
|
|
to translate English speech into Prolog
|
|
|
|
|
|
The last one is the coolest - but you may need to enable the ``speech_input`` command by installing ATK
|
|
and recompiling GF.
