Discussion

Vaccine Ontology

[09:16] Tiago Lubiana: Now the scraper has run, here is the auto mappings and suggestions for the Vaccine Ontology: https://mix-n-match.toolforge.org/#/catalog/5849

[09:19] Asiyah Yu Lin - NIAID: Tiago, we could work with you on VO and Wikidata. I will connect you with Oliver He.

[09:20] Tiago Lubiana: Thanks Asiyah! I set up the mapping infrastructure, but I cannot actually work on that for the moment. Hopefully in the future!

[09:21] Asiyah Yu Lin - NIAID: I believe that's the same for Oliver. A lot on plate now. I will circle back to you.

Wikidata Disambiguation

[09:33] Vincent Vialard: having worked on entity disambiguation using addresses, i can testify that places are NOT well defined in wikidata. it checks most of the issues listed by gary...

[09:36] Tiago Lubiana: There is some discussion on schemas on subdomains here: https://www.wikidata.org/wiki/Wikidata:WikiProject_Schemas

Detecting Misinformation

[09:38] Tiago Lubiana: yep, that is a good point. It is relatively simple to go back and fix once bullshit is spotted, though

[09:39] James Overton: I accept Vincent's point that stuff like ChatGPT generates BS that can be harder to my BS detector to detect.

[09:40] Tiago Lubiana: one thing that Wikidata has that is kind of unique is the open "Discussion" forums on each entry on Wikidata, where people can agree and disagree on an entity-by-entity basis

[09:44] Tiago Lubiana: @Vincent this article discusses just that: classes, metaclasses and ontological disarray on Wikidata: https://nemo.inf.ufes.br/wp-content/papercite-data/pdf/type_or_individual_evidence_of_large_scale_conceptual_disarray_in_wikidata_2021.pdf

[09:45] Tiago Lubiana: Also, people are working on subsetting Wikidata to extract subdomains that might be more structured using ShEx: https://www.semantic-web-journal.net/content/wikidata-subsetting-approaches-tools-and-evaluation

[09:46] Tiago Lubiana: It is searchable in SPARQL, so it can be converted in RDF

Literals

[09:50] Tiago Lubiana: I don't know if I understood it completely the question, James, sorry!

Here are the Wikidata dumps: https://www.wikidata.org/wiki/Wikidata:Database_download

Wikibase has some different datatypes that might play the role of Literals: https://www.wikidata.org/wiki/Help:Data_type

[09:51] James Overton: No worries. Your answer was good! Thanks

Wikidata Channel

[09:51] Tiago Lubiana: (I do have to leave now, unfortunately, thank you for opening this space! We have a Wikidata channel in the OBO slack by the way, if anyone has other questions: https://obo-communitygroup.slack.com/archives/C0440CBHYA3)

KGSQL

[09:52] Vincent Vialard: https://ken.baclawski.com/pub/2021/47/public.pdf

DBPedia

[09:56] James Overton: This page discusss DBPedia and Wikidata, but I'm still a bit confused: https://meta.wikimedia.org/wiki/Wikidata/Notes/DBpedia_and_Wikidata
