rdfs:label (as per DBpedia documentation every entity has an rdfs:label reference).
One of the benefits of the cleaned up pagelink dataset is the faster computation of statistical graph measures (while not influencing the overall statistics, i.e. redirect pages usually don't have incoming links and theother removed resources (as e.g. images) don't have outgoing links). Based on this dataset we have computed PageRank, Hub and Authorities (HITS), PageInlink Counts and PageOutLink Counts. Please find the details of the datasets here on our research group's webpage .
For Computation of the DBpedia graph statistics we have used JUNG — the Java Universal Network/Graph Framework. Please find the source code for PageRank and HITS computation here via GitHub .
