Hi Andreas, Chris, and everybody, Yesterday at the Consuming Linked Data Workshop I was asked about making public the set of class-level mappings produced from the BTC2009 data, which I mentioned in my presentation. I have put a dump to http://people.kmi.open.ac.uk/andriy/mappings-btc.nt for now, Chris, I can put those to R2R if it's ok. In short, this is a set of class subsumption mappings (about 50000) produced from the overlapping instance sets in the Billion Triple Challenge 2009 dataset using a light-weight machine-learning method. As i said, there is some noise in the set because (a) machine learning was not 100% accurate (precision around 90% measured using cross-validation on a training set) and (b) some info became obsolete since last year. Best regards, Andriy Nikolov -- The Open University is incorporated by Royal Charter (RC 000391), an exempt charity in England & Wales and a charity registered in Scotland (SC 038302).
