Hi Arun,
DBpedia has two 'modes' the static one, served from http://dbpedia.org and
the live one served from http://live.dbpedia.org.
Static DBpedia is updated once or twice a year with the latest update using
data from May/June 2012 [1]
The article you are looking into is created last month [2] so it does not
exists at all in static dbpedia
You can use the live dbpedia for that (but there are some technical
problems right now so try later)
For improving the framework you can use our online mapping wiki
http://mappings.dbpedia.org
Best,
Dimitris
