Hi,

you might want to have a look at the JWPL Revision Toolkit

It should provide most information you are looking for, especially access to all the modifications and a parser to extract the plain text from Wikipedia.

The UIMA toolkit

http://code.google.com/p/dkpro-core-asl/

also contains a component that gets you all pairs of adjacent revisions from which makes it quite easy to spot the ones which are additions only.

Subject: [Wiki-research-l] Wikipedia Users database

Hi,

I am planning to study the difference in users edits style and their spelling errors in English Wikipedia as part of a research project I am involved in.

So I downloaded some of the wikipedia XML partial dump and convert them to SQL. My understanding that wikipedia stores every copy of the pages in the database.

I can not see the users table! Is the users table stored in a special partial dump?
Does the user table contain any properties related to the user country, preferred wikipeidas, or their skill in different languages ?
I am interested in the user modifications that contain addition to the articles and not modification or deletion. I am planning now to diff between revisions to get such data. Are you aware of any tool or effort that can help?
Are you aware of any tools that extract the text from wikipedia markup language.

Regards.
