At Meta, I have been involved in writing up about research sprints, translating documents and messages. See also my WikiCV.

Alternative accountsEdit

Here is a list of accounts I have used.

My research sprints and software toolsEdit


  • WikiHadoop - a Hadoop module to easily split and distribute compressed MediaWiki dump XMLs to a number of computing nodes.
  • RevDiffSearch - a full-text search system to enable efficiently finding revisions containing a given text fragment.
  • WikiSentiment - a sentiment analysis system to classify talk page messages by learning from coded messages.


Wikidoop Barnstar

I award you the Wikidoop Barnstar for your tireless work on getting Hadoop and the Wikimedia XML files to live peacefully together. Drdee 13:46, 21 July 2011 (UTC)
