  • Query examples:
    • Apologies for both of the problematic queries ("MWAPI searches in wikidata about people described as slave traders by citizenship" in Weekly Summary #419 and "Monuments named after/commemorating/depicting slave traders” in Weekly Summary #420). The "MWAPI searches in wikidata about people described as slave traders by citizenship” in #419 lists any people with the word "slave" in a label, description or alias, among them several people who are not slave traders. The "Monuments named after/commemorating/depicting slave traders” in #420 incorrectly linked this query for enslaved people instead of this query for slavetraders.

• Development
  • The last week was our quarterly prototyping week. We worked on the following projects. None of them are ready for prime-time yet but we'll continue with them.
    • Slices: We've had a lot of requests for accessing dumps of a smaller part of Wikidata's data since rarely anyone needs the complete data in Wikidata. The tricky part is figuring out which part is needed and if any of that can be generalized. We looked into for example how to make dump generation faster so we could potentially produce more smaller dumps that only cover a part of Wikidata's data, either thematically (e.g. humans) or by type of data (e.g. only statements and English labels and aliases but not sitelinks or descriptions).
    • REST API: As part of our effort to make it easier to access Wikidata's data for programmers we looked into a REST API. We tried to see if we could cover the existing action API modules in a REST API. We could. We'll take this as input for our ongoing API work now.
    • Improving quality ratings through ORES: ORES can judge the quality of an Item automatically. It is currently not very good at it however. We tried a few things to make it more accurate and found some easy wins we'll probably make happen in the next weeks.
    • Query manipulator: One of the ways we could potentially improve the load situation of the Wikidata Query Service is by automatically analyzing and then redirecting a bunch of queries to other systems that are more suitable for that particular type of query. The nice thing about that would be that the person/program sending the query wouldn't have to care about it but it'd be done automagically for them. We tried to build such a system and the results look very promising but more work/experimenting is needed, especially together with the WMF Search team.
