The structure of each lecture will be the following:
|
|
</P>
|
|
<UL>
|
|
<LI>ca. 75min lecture, going through the book
|
|
<LI>ca. 15min work on computer, individually or in pairs
|
|
</UL>
|
|
|
|
<P>
|
|
In order for this to work out, it is important that enough many
|
|
have a working GF installation, including the directory
|
|
<A HREF="../examples/tutorial"><CODE>examples/tutorial</CODE></A>. This directory is
|
|
included in the Darcs version, as well as in the updated binary
|
|
packages from 12 September.

<H1>Purpose</H1>
|
|
<P>
|
|
<A HREF="http://www.cs.chalmers.se/~aarne/GF/">GF</A>
|
|
(Grammatical Framework) is a grammar formalism, i.e. a special-purpose
|
|
programming language for writing grammars. It is suitable for many
|
|
natural language processing tasks, in particular,
|
|
</P>
|
|
<UL>
|
|
<LI>multilingual applications
|
|
<LI>systems where grammar-based components are needed for e.g.
|
|
parsing, translation, or speech recognition
|
|
</UL>
|
|
|
|
<P>
|
|
The goal of the course is to develop an understanding of GF and
|
|
practical skills in using it.
|
|
</P>
|
|
<H1>Contents</H1>

|
The course consists of two modules. The first module is a one-week
|
|
intensive course (during the first intensive week of GSLT), which
|
|
is as such usable as a one-week intensive course for doctoral studies,
|
|
if completed with a small course project.
|
|
</P>
|
|
<P>
|
|
The second module is a larger programming project, written
|
|
by each student (possibly working in groups) during the Autumn term.
|
|
The projects are discussed during the second intensive week of GSLT
|
|
(see <A HREF="http://www.gslt.hum.gu.se/courses/schedule.html">schedule</A>),
|
|
and presented at a date that will be set later.
|
|
</P>
|
|
<P>
|
|
The first module goes through the basics of GF, including
|
|
</P>
|
|
<UL>
|
|
<LI>using the GF programming language
|
|
<LI>writing multilingual grammars
|
|
<LI>using the
|
|
<A HREF="http://www.cs.chalmers.se/~aarne/GF/lib/resource-1.0/doc/">GF resource grammar library</A>
|
|
<LI>generating speech recognition systems from GF grammars
|
|
<LI>using embedded grammars as components of software systems
|
|
</UL>
|
|
|
|
<P>
|
|
The lectures follow a draft of GF book. It contains a heavily updated
|
|
version os the
|
|
<A HREF="http://www.cs.chalmers.se/~aarne/GF/doc/tutorial/gf-tutorial2.html">GF Tutorial</A>;
|
|
thus the on-line tutorial is not adequate for this course. To get the course
|
|
book, join the course mailing list.
|
|
</P>
|
|
<P>
|
|
Those who just want to do the first module will write a simple application
|
|
as their course work during and after the first intensive week.
|
|
</P>
|
|
<P>
|
|
Those who continue with the second module will choose a more substantial
|
|
project. Possible topics are
|
|
</P>
|
|
<UL>
|
|
<LI>building a dialogue system by using GF
|
|
<LI>implementing a multilingual document generator
|
|
<LI>experimenting with synthetized multilingual tree banks
|
|
<LI>extending the GF resource grammar library
|
|
</UL>
|
|
|
|
<H1>Prerequisites</H1>
|
|
<P>
|
|
Experience in programming. No earlier natural language processing
|
|
or functional programming experience is necessary.
|
|
</P>
|
|
<P>
|
|
The course is thus suitable both for GSLT and NGSLT students,
|
|
and for graduate students in computer science.
|
|
</P>
|
|
<P>
|
|
We will in particular welcome students from the Baltic countries
|
|
who wish to build resources for their own language in GF.
