Errata Mistakes happen. This is a list of some errata found in the published versions of the works listed above (works with errata have been marked above with the following symbol: ). The errata listed have been corrected in the pre-print versions linked above. In the published version "Modelling Dynamics in Semantic Web Knowledge Graphs with Formal Concept Analysis", we stated Mean Average Error (MAE), when we intended to say Mean Absolute Error (MAE). Also on line 20 of Algorithm 1, B_i should rather be B_j'. This is corrected in the version linked above. In a pre-print version of "Canonical Forms for Isomorphic and Equivalent RDF Graphs: Algorithms for Leaning and Labelling Blank Nodes", Definition 3.18 forgot to specify that G' be a subset of G. Thanks to Antoine Zimmermann for pointing out this issue, along with some other minor comments! (I'm hoping to correct for the published version.) Furthermore, in the published version, on P24, second paragraph, as well as in Example 4.15: [_:a,_:c] should read [_:a,_:b]; [_:c,_:a] should read [_:c,_:b]; [_:c,_:i] should read [_:c,_:f]; and [_:a,_:g] should read [_:a,_:d]. Also in Algorithm 3, the recursion of the distinguish function requires making a copy of the array. Thanks to Ivan Herman for these latter corrections! Finally, Manu Sporny has pointed out that his joint (and earlier) work with Dave Longley on producing canonical labels for blank nodes was not cited in this paper; we have added this missing reference and given due credit to this earlier work. These issues are resolved in the version linked above. In the published version of "Reifying RDF: What Works Well With Wikidata?", in Table 5 and Figure 3, the standard reification and n-ary relations columns were mixed up; also, the minimum y-value (100 ms) used for Figure 3 was higher than the runtime of two query executions for Virtuoso (Q7: NR SP), which thus did not appear in the figure. These errors are fixed in the version above. In the published version of "Everything you always wanted to know about blank nodes", there was a bug with how SPARQL SELECT queries were used to find non-lean graphs: we neglected to address automorphisms that would cause graphs to appear non-lean when they were actually lean. The discussion at the end of Section 4.2 and Algorithm 5 have been updated accordingly to fix the issue in the version linked here. (Here's some more details on the error I sent to my co-authors.) Also, in Theorem 3.5, it was stated that G entails H if and only if I(H) is contained in I(G); this should have stated if and only if I(G) is contained in I(H). Finally we removed a duplicate node in Figure 1 (thanks to Georg Lausen). These errors are fixed in the pre-print above. In the published version of the Hogan book chapter in Linked Data Management, in the first definition, I had stated "U B Lp Lt = " to indicate that the sets were pair-wise disjoint; however, this does not ensure that the sets are pair-wise disjoint, just that there is no element of all four sets. The erroneous notation has been removed from the pre-print linked above. (Thanks to Basil Ell for pointing this out!) In the published version of the Buil-Aranda et al. paper at ISWC 2013, the percentage of endpoints falling into the availability intervals discussed in Section 5.2 did not add up to 100% but rather to 97%. Most notably, in the 95 99% interval, the percentage should be 17.4%, not 14.4%. This has been corrected in the pre-print linked above. (Thanks to Ruben Verborgh for pointing this out!) If you found another error in one of the works listed above, please get in contact so I can list it here. It would be much appreciated!
