query.wikidata.org and wikibase:Statement ?
by Egon Willighagen 08 Jan '16

08 Jan '16

Hi all, after a tweet from Magnus [0] we talked a bit about entries without statements (about 2.5M) and on the question if SPARQL could list all entries in Wikidata that do not have statements. I played a bit with combinations of OPTIONAL and FILTER-BOUND and FILTER NOT EXIST... something like: PREFIX wikibase: <http://wikiba.se/ontology#> SELECT DISTINCT ?entry ?label ?statement WHERE { ?entry rdfs:label ?label . FILTER (lang(?label) = "en") FILTER NOT EXISTS { ?statement ?prop ?entry ; wikibase:rank ?rank . } } LIMIT 5 These queries tend to fail. Now, I'm not at all a SPARQL wizard and maybe there is a simple way to not run into the time outs that I do now. But there was something else I noted... statements are not typed... that would probably kick in some index, rather than the above query, and the documentation actually speaks about wikibase:Statement [1] but if I search for anything rdf:type-d as such, then it finds nothing in the SPARQL end point: https://query.wikidata.org/#PREFIX%20wikibase%3A%20%3Chttp%3A%2F%2Fwikiba.s… Did this typing get lost at some point or is the documentation outdated?

Music data, Wikidata and FRBR
by Federico Leva (Nemo) 03 Jan '16

03 Jan '16

At BEIC, to test the Wikidata ontology and the feasibility of collaborations on music data, I was assigned a seemingly simple test: add in Wikidata all the data contained in https://en.wikipedia.org/wiki/Brown_Sugar_(The_Rolling_Stones_song) . Turns out things are not so simple: * the Wikipedia articles, from an FRBR (https://en.wikipedia.org/wiki/FRBR ) perspective, often mix multiple levels or even all of them (song, recording, album, single, edition of the single) which on Wikidata need to be separate items, but the split is not obvious: https://www.wikidata.org/wiki/Special:WhatLinksHere/Q21887964 ; * I was unable to properly add information on per-country hit list position. Please give a look to the items I linked, to my https://www.wikidata.org/wiki/Wikidata:WikiProject_Music updates and to the open questions I added in https://www.wikidata.org/wiki/Wikidata_talk:WikiProject_Music . In particular, I think librarians will be interested in this proposal for a "performance of" property, which (like the existing "edition of" property) could benefit from being framed in a FRBR perspective by someone more versed in FRBR. https://www.wikidata.org/?diff=287456096 Nemo-BEIC

Teaching machines to make your life easier – quality work on Wikidata
by Amir Ladsgroup 02 Jan '16

02 Jan '16

Hey, New blog post <http://blog.wikimedia.de/2016/01/02/teaching-machines-to-make-your-life-eas…> and some analysis is out. It turns out if we use ORES properly it can reduce the workload of reviewing human edits by 99%. If you help and label edits in Edit labels <https://www.wikidata.org/wiki/Wikidata:Edit_labels>, We can both efficiently revert vandalism and route good-faith newcomers to support and training.

Duplicates in Wikidata
by Proffitt,Merrilee 01 Jan '16

01 Jan '16

Hello colleagues, During the most recent VIAF harvest we encountered a number of duplicate records in Wikidata. Forwarding on in case this is of interest (there is an attached file – not sure if that will go through on this list or not). Some discussion from OCLC colleagues is included below. Merrilee Proffitt, Senior Program Officer OCLC Research From: Toves,Jenny Sent: Tuesday, December 22, 2015 6:02 AM To: Proffitt,Merrilee Subject: FW: 201551 vs 201552 Good morning Merrilee, You probably know that we harvest wikidata monthly for ingest into VIAF. This month we found 315 pairs of records that appear to be duplicates. That was a jump from previous months. I am not sure who would be interested in this but Thom & I thought you might be. The attached report has 630 lines showing what viaf saw as duplicates. So this pair of lines: WKP|Q21518392 =998 $aCharles du Bois Larbalestier$2WKP|Q21341290$3duplicate WKP|Q21341290 =998 $aCharles du Bois Larbalestier$2WKP|Q21518392$3duplicate Shows that those two wikidata numbers are linked to one another by viaf. I don’t think we expect you to do anything with this unless you find it interesting. I suspect there are bots to clean this stuff up but maybe not. --Jenny. From: Hickey,Thom Sent: Monday, December 21, 2015 9:47 PM To: Toves,Jenny Subject: RE: 201551 vs 201552 She probably would be interested. --Th From: Toves,Jenny<mailto:[email protected]> Sent: Monday, December 21, 2015 9:35 PM To: Hickey,Thom<mailto:[email protected]> Subject: RE: 201551 vs 201552 Exact same name + dates. Do you a list of them? Do you think Merrilee or anyone would be interested? From: Hickey,Thom Sent: Monday, December 21, 2015 8:04 PM To: Toves,Jenny Subject: FW: 201551 vs 201552 Noticed WKP duplicates went way up --Th From: Jenny Toves<mailto:[email protected]> Sent: Monday, December 21, 2015 5:12 PM To: Hickey,Thom<mailto:[email protected]>; Toves,Jenny<mailto:[email protected]> Subject: 201551 vs 201552 REPORT for records Changed 13.51%: geographic 3369217.0 -> 3824513.0 Change in % of 8: NLR at_least_one_match 16% -> 24% Changed 19.83%: NLR all_matches 181437.0 -> 217423.0 Change in % of 88: NLR with_bibs 0% -> 88% Changed 17.99%: WKP geographic 2529990.0 -> 2985194.0 Changed -19.95%: WKP corporate 369224.0 -> 295579.0 REPORT for matches Changed 12.70%: exact corporate name 1021239.0 -> 1150899.0 Changed 14.29%: XR viafid 7.0 -> 8.0 Changed -10.42%: XR expression title to sibling 48.0 -> 43.0 Changed -16.16%: PTBNP forced 229.0 -> 192.0 Changed -37.50%: NSZL forced 8.0 -> 5.0 Changed 38.46%: NLP suggested 13.0 -> 18.0 No longer zero: NLR standard number 0.0 -> 21479.0 No longer zero: NLR exact title 0.0 -> 5166.0 No longer zero: NLR partial date and partial title 0.0 -> 618.0 No longer zero: NLR name as subject 0.0 -> 62.0 No longer zero: NLR partial title and publisher 0.0 -> 88.0 No longer zero: NLR title 0.0 -> 5093.0 Changed -47.66%: NLR forced single date 37125.0 -> 19430.0 Changed 14.29%: NLR viafid 14.0 -> 16.0 No longer zero: NLR partial date and publisher 0.0 -> 15894.0 No longer zero: NLR joint author 0.0 -> 5228.0 Changed -14.49%: LC suggested 7594.0 -> 6494.0 Changed 33.33%: CYT viafid 12.0 -> 16.0 Changed -21.08%: NLA forced 223.0 -> 176.0 Changed 233.33%: LNL forced 3.0 -> 10.0 Changed 12.50%: NLB viafid 8.0 -> 9.0 Changed 16.67%: NLB ngram corporate name 6.0 -> 7.0 Changed 25.71%: VLACC forced 35.0 -> 44.0 Changed 19.13%: DNB exact corporate name 315872.0 -> 376304.0 Changed 14.29%: DNB expression title to sibling 7.0 -> 8.0 Changed 16.67%: BNF expression title to sibling 6.0 -> 7.0 Changed 15.91%: ICCU forced 44.0 -> 51.0 Changed 25.54%: NTA forced 9699.0 -> 12176.0 Changed 28.62%: WKP exact corporate name 224787.0 -> 289112.0 Changed 23.73%: WKP longer corporate name 76057.0 -> 94106.0 Changed 584.78%: WKP duplicate record 92.0 -> 630.0 Changed -18.92%: EGAXA forced 37.0 -> 30.0 REPORT for tags Changed 11.56%: NSZL work links (993) 225.0 -> 251.0 No longer zero: NLR wrote about (955) 0.0 -> 106.0 No longer zero: NLR bibs (999) 0.0 -> 108202.0 No longer zero: NLR was a subject (960) 0.0 -> 16423.0 No longer zero: NLR relator code (941) 0.0 -> 103950.0 No longer zero: NLR language of work (940) 0.0 -> 108193.0 No longer zero: NLR issn (902) 0.0 -> 34.0 No longer zero: NLR bib title (910) 0.0 -> 107895.0 No longer zero: NLR joint corporate author (951) 0.0 -> 24235.0 Changed 146.67%: NLR compared (996) 27448.0 -> 67705.0 No longer zero: NLR rectype + biblvl (944) 0.0 -> 108194.0 No longer zero: NLR country of publication (922) 0.0 -> 108169.0 No longer zero: NLR publisher (921) 0.0 -> 93904.0 No longer zero: NLR isbn (901) 0.0 -> 78978.0 No longer zero: NLR publisher id (920) 0.0 -> 78978.0 Changed 50.05%: NLR matched (998) 19864.0 -> 29806.0 No longer zero: NLR name from statement of responsibility (930) 0.0 -> 72478.0 No longer zero: NLR noise title (912) 0.0 -> 3543.0 No longer zero: NLR lc class number (942) 0.0 -> 1.0 No longer zero: NLR joint author (950) 0.0 -> 69048.0 No longer zero: NLR was a subject (969) 0.0 -> 115.0 Changed -14.29%: XA work links (993) 7.0 -> 6.0 No longer zero: SRP work links (993) 0.0 -> 1.0 Changed 22.50%: BNL work links (993) 551.0 -> 675.0 Changed 11.16%: WKP auth title (919) 45779.0 -> 50890.0 Changed 12.56%: WKP noise title (912) 8249.0 -> 9285.0
