Hi Shailly,<br><br>There are non-projective approaches to dependency parsing, one of the more recent of which is McDonald's MSTParser. You can find information here:<br><br><a href="http://www.seas.upenn.edu/~strctlrn/MSTParser/MSTParser.html">
http://www.seas.upenn.edu/~strctlrn/MSTParser/MSTParser.html</a><br><br>The parser itself can be downloaded from:<br><br><a href="http://sourceforge.net/projects/mstparser">http://sourceforge.net/projects/mstparser</a><br>
<br>You might also look at Nivre's MaltParser, which is "pseudo-projective":<br><br><a href="http://w3.msi.vxu.se/~nivre/research/MaltParser.html">http://w3.msi.vxu.se/~nivre/research/MaltParser.html</a><br>

<div> </div>
<div>Although my doubt does not exactly suit in this mailing list, I would like to know why planarity (projectivity) is required for dependency parsing? Many sentences of languages such as German, Hindi are not planar. Does this mean that dependency based parsing is not suitable for these languages?
