Hi Dimitris,
Thanks for your reply. I see that the Namespace.scala is indeed fixed in the
dump branch. Actually I'm a bit confused about all the branches that are
available at the site. Is there a place which details about all the branches in
the mercurial repository of the extraction_framework. Which one should I use? I
had checked out the default branch and did a hg update/pull sometime back. I'm
used to working with SVN which has a concept of a stable trunk . This mercurial
business seems to get confusing.
Regards
Amit

Subject: Re: [Dbpedia-discussion] Error in running the Dbpedia Extraction
Framework on Oct dump of Enwiki
Hi Amit,
you can look at the following thread for the error details.
http://sourceforge.net/mailarchive/message.php?msg_id=30145224
If you switch to dump branch things should work fine, however, If you need the
wiktionary branch we were planning to deploy Jona's patch to all branches
anyway so we might speed up th procedure :)
Best,
Dimitris

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 ?
