Thanks a lot! I added labels in P10540#61224 <https://phabricator.wikimedia.org/P10540#61224>. In combination with the total counts from T244341#5920206 <https://phabricator.wikimedia.org/T244341#5920206>, my interpretation of the top entries is: - Out of the 77859 “described by source: //unknown value//” statements, 77855 have a “named as” qualifier. **In “described by source”, //unknown value// virtually always means “some value, see ‘named as’”.** Other common qualifiers, such as “determination method” and various external identifiers, seem unrelated to the interpretation of the //unknown value// snak. - Out of the 57564 “publisher: //unknown value//” statements, 56081 have a “stated as” qualifier. **In “publisher”, //unknown value// overwhelmingly means “some value, see ‘stated as’”.** (I’m vaguely curious if the choice of “named as” vs. “stated as” has any significance, or if it’s just the result of two different people doing separate imports and happening to pick different but related properties.) - Out of the 13772 “date of death: //unknown value//” statements, 4143 have an “earliest date” qualifier, and 864 have a “latest date” qualifier. **In “date of death”, //unknown value// usually does mean “unknown”, though the qualifiers can sometimes constrain the possible range.** - Out of the 12792 “given name: //unknown value//” statements, almost none have any qualifier at all (top entry in P10540 <https://phabricator.wikimedia.org/P10540> is “applies to part”, 34 times). **In “given name”, //unknown value// means “unknown”.** I’m not sure in which case this would be used, by the way – even if the external source only recorded an initial, for example, we have items we can use for that (such as S. <https://www.wikidata.org/wiki/Q19803518>) instead of //unknown value//. - Out of the 10054 “date of birth: //unknown value//” statements, 690 have a “latest date” qualifier, and 384 have an “earliest date” qualifier. **In “date of birth”, like in “date of death”, //unknown value// usually means “unknown”, possibly constrained by qualifiers.** - Out of the 5398 “place of birth: //unknown value//” statements, almost none have any qualifier at all (top entry in P10540 <https://phabricator.wikimedia.org/P10540> is “country”, 42 times). **In “place of birth”, //unknown value// means “unknown”.** Those cases with a “country” qualifier should probably just enter the country directly into the statement? - Out of the 5397 “inception: //unknown value//” statements, 336 have a “latest date” qualifier, and 273 have an “earliest date” qualifier. **In “inception”, //unknown value// means “unknown”, as in “date of birth/death”.** - ...skipping some... - On the 1534 “editor: //unknown value//” statements, there are 2192 “stated as” qualifiers and 1630 “series ordinal” qualifiers. This doesn’t really match up (possibly due to the analyses having run at different times? could somebody have added that many other “editor” statements in between?), but it seems that **in “editor”, //unknown value// typically means “some value, see ‘stated as’”.** In conclusion: “unknown value” actually meaning “unknown value” is still common (especially for “time”-type properties); that said, the most common uses really mean “some known value that doesn’t have an item yet”.
