Constructing and Cleaning Identity Graphs in the LOD Cloud

This data set contains all the 49 million non-singleton equivalence classes resulting from the transitive closure of over 556 million owl:sameAs statements extracted from the LOD Cloud in the 2015 LOD Laundromat crawl. In addition to the closure of all owl:sameAs links, this data set contains an additional two transitive closures: closure_099 representing the closure of these owl:sameAs links after discarding around 1 million links with an error degree >0.99, and closure_04 after discarding around 150 million links with an error degree >0.4. This error degree and our choice for the subsets are described in the paper "Constructing and Cleaning Identity Graphs in the LOD Cloud" published in the Data Intelligence journal.
