This is a little project to visualize owl:sameAs links in the Billion Triple
Challenge Dataset: http://challenge.semanticweb.org/
After downloading the BTC data into a directory called data you can generate
the json file that is used to display the graph with the following:
zgrep -h 'http://www.w3.org/2002/07/owl#sameAs' data/btc-2010-chunk-*.gz | \
scripts/quadtab.pl | \
scripts/sameas.py | \
sort | uniq -c | \
scripts/jsonify.py > docs/sameas.js
You'll need to have recent-ish versions of Perl, Python and pygraph installed.
