Comparing Extracted and dblp Editors

• editor by volume comparison
  • 2233 volume the extracted editors match the dblp editors
  • 807 volumes are missing in dblp (editors extracted)
  • 27 volumes more editors were extracted than in dblp
  • 387 volumes dblp has more editors than we could extract
• 9321 out of 11764 editor records can be reconciled
  • 79.23%

Wikidata Reconciliation

Using the ids queried from dblp to find the corresponding wikidata entry.

Current strategy:

Input

List of different identifiers that are known about a editor

Output

SPARQL query

Example:

• Input:
  • homepage: http://www.stefandecker.org
  • gnd id: 173443443
  • dblp author id: d/StefanDecker
• Output:

PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT DISTINCT ?person ?personLabel
WHERE
{
  {OPTIONAL{ ?person wdt:P856 <http://www.stefandecker.org>.} }
  UNION
  {OPTIONAL{ ?person wdt:P227 "173443443".} } # gnd
  UNION
  {OPTIONAL{ ?person wdt:P2456 "d/StefanDecker".} } # dblp
  ?person rdfs:label ?personLabel. FILTER(lang(?personLabel)="en")
}

Depending on the available identifiers the query is adjusted accordingly by adding the corresponding OPTIONAL clauses.

Running these queries for all 4942 editors known by dblp we get:

• 1467 editors were found in wikidata
• 62 editor records in dblp have a conflict with wikidata
• 3413 dblp editor records were not found in wikidata

The figure below shows the distribution of the available identifiers depending of the three categories identified, conflict, unkown

dblp in-sync with wikidata?

Using all ids we get from dblp to look up wikidata ids yields 1467 Qids (+62 with conflicts). Comparing this to the wikidata ids that are already available in dblp (with the query below):

PREFIX datacite: <http://purl.org/spar/datacite/>
PREFIX dblp: <https://dblp.org/rdf/schema#>
PREFIX litre: <http://purl.org/spar/literal/>
SELECT DISTINCT 
	(group_concat(DISTINCT ?nameVar;separator='|') as ?name) 
	(group_concat(DISTINCT ?wikidataVar;separator='|') as ?wikidata)
WHERE{
	?proceeding dblp:publishedIn "CEUR Workshop Proceedings";
		dblp:publishedInSeriesVolume ?volume;
		dblp:editedBy ?editor.
	?editor dblp:primaryCreatorName ?nameVar.
	?editor datacite:hasIdentifier ?wikidata_blank.
	?wikidata_blank datacite:usesIdentifierScheme datacite:wikidata;
					litre:hasLiteralValue ?wikidataVar.
}
GROUP BY ?editor

The query yields 1390 (1446 with conflicts) editors with wikidata ids. Thus, with the wikidata queries we were only able to get 77 additional Qids indicating that dblp synchronizes their editor records with the additional ids that are available at wikidata.
