Hi,
Why have I got title using Wikipedia Miner different from one using Wikimedia API ("Computer software" vs. "Software")? .
When I explored article by query (http://wikipedia-miner.cms.waikato.ac.nz/services/exploreArticle?title=software&labels=true),
it redirected to article with name "Computer software"
However, the title got from Wikimedia API is different (see: http://en.wikipedia.org/w/api.php?action=query&prop=revisions&titles=Computer%20software&rvprop=timestamp|content&rvstart=27%20Jul%202011%2002:14:27%20GMT&rvdir=older&rvlimit=1&format=xml&redirects)
It responded the same article with tile "Software". I queried the article with old version (before 27 Jul 2011, the version of Wikipedia used in Wikipedia Miner)

Thanh you for helps!
