Hi all,
I'm have been running dbpedia extraction framework on wikipedia dumps. It was
working fine but recently it has started giving error. I'm using the following
version of the code
--------------
changeset: 1610:59dda670016e
branch: wiktionary
tag: tip
parent: 1609:a71b7d4bf8d1

summary: merge default into wiktionary again
-------------------
You can find the error code below. From my understanding the problem lies in
the NameSpace file
http://dbpedia.hg.sourceforge.net/hgweb/dbpedia/extraction_framework/file/tip/core/src/main/scala/org/dbpedia/extraction/wikiparser/Namespace.scala
My guess is that wikipedia has added a new namespace recently which is still
not added to the above file and this is the reason for the exception. You can
check wikipedia at http://en.wikipedia.org/wiki/Wikipedia:Namespace
710 corresponds to
TimedText<http://en.wikipedia.org/wiki/Wikipedia:TimedText_namespace> Namespace
Please let me know if I'm correct and if anyone has seen/fixed the same issue ?
