<h1>Grammatical Framework Quick Start</h1>
|
|
|
|
</center>
|
|
|
|
This Quick Start shows two examples of how GF can be used.
|
|
We assume that you have downloaded and installed GF, so that
|
|
the command <tt>gf</tt> works for you. See download and install
|
|
instructions <a href="../download/index.html">here</a>.
|
|
|
|
|
|
|
|
<h2>Translation and generation</h2>
|
|
|
|
When you have downloaded and installed GF:
|
|
<ol>
|
|
<li> Copy the files
|
|
<a href="../examples/tutorial/food/Food.gf"><tt>Food.gf</tt></a>,
|
|
<a href="../examples/tutorial/food/FoodEng.gf"><tt>FoodEng.gf</tt></a>, and
|
|
<a href="../examples/tutorial/food/FoodIta.gf"><tt>FoodIta.gf</tt></a>.
|
|
Or go to <tt>GF/examples/tutorial/food/</tt>, if you have downloaded the
|
|
GF sources.
|
|
|
|
<li> Start GF with the command
|
|
<pre>
|
|
gf FoodIta.gf FoodEng.gf
|
|
</pre>
|
|
|
|
<li> <b>Translation</b>. Try your first translation by giving the GF command
|
|
<pre>
|
|
parse "this cheese is very very Italian" | linearize -treebank
|
|
</pre>
|
|
|
|
<li> <b>Generation</b>. Random-generate sentences in two languages:
|
|
<pre>
|
|
generate_random | linearize
|
|
</pre>
|
|
|
|
<li> <b>Grammar development</b>. Add words to the <tt>Food</tt>
|
|
grammars and try the above commands again. For instance, add the following lines:
|
|
<pre>
|
|
Bread : Kind ; -- in Food.gf
|
|
Black = {s = "bread"} ; -- in FoodEng.gf
|
|
Black = {s = "pane"} ; -- in FoodIta.gf
|
|
</pre>
|
|
and start GF again with the same command. Now you can even translate
|
|
<i>this bread is very Italian</i>.
|
|
</ol>
|
|
To lear more on GF commands and
|
|
grammar development, go to the one of the tutorials:
|
|
<ul>
|
|
<li> <a href="tutorial/gf-tutorial.html">GF Tutorial</a>: older, more programmer-oriented
|
|
<li> <a href="gf-lrec-2010.pdf">GF Resource Tutorial</a>: newer, more linguist-oriented
|
|
</ul>
|
|
To learn about how GF is used for easily writing grammars for 16 languages, consult the
|
|
<ul>
|
|
<li> <a href="../lib/doc/synopsis.html">GF Resource Grammar Library</a>.
|
|
</ul>
|
|
|
|
|
|
|
|
<h2>Run-time grammars and web applications</h2>
|
|
|
|
GF has its own "machine language", PGF (Portable Grammar Format),
|
|
which is recommended for use in applications at run time. To produce a PGF file from
|
|
the two grammars above, do
|
|
<pre>
|
|
gf -make FoodIta.gf FoodEng.gf
|
|
wrote Food.pgf
|
|
</pre>
|
|
You can use this in Haskell and Java programs, and also on web services, as shown in
|
|
<a href="http://www.grammaticalframework.org:41296/minibar/minibar.html">here</a>.
|
|
To build your own web application, consult the
|
|
<a href="http://code.google.com/p/grammatical-framework/wiki/SideBar?tm=6">developer wiki</a>.
