<div>Dear collegues,</div>
<div>I would like to be able to show to my students how a
context-free grammar does work. I don't need an optimized parser for
context-free grammars, but I guess an applet with graphics or similar
simulator (best if opensource) would do the trick.</div>

You can check out FreeLing (<a class="moz-txt-link-freetext" href="http://www.lsi.upc.edu/~freeling">http://www.lsi.upc.edu/~freeling</a>)<br>
<br>
It's an open source language analysis suite which includes a chart
parser, which is run on the output of a PoS tagger.<br>
You can write your own grammar and provide it as a parameter to the
analyzer. <br>
Currently, PoS tagging for Spanish, English, Italian, Catalan and
Galician is available, so you can write grammars for any of these
languages.<br>
