As there is no formal representation theory for qualifiers, any categorization
of them is unlikely to totally describe their potential usage. I tried to
come up with a categorization that reflects property descriptions and a small
sample of usage.
So I categorized stated as (P1932) as no information because I see it being
used only to provide surface syntax from the source use. The Wikidata value
of the statement then provides the totality of the Wikidata meaning of the
statement. It is certainly possible that the source provides more meaning
than is captured in Wikidata, but that's outside of Wikidata.
I see determination method (P459) as mostly providing information to Wikidata
as to how much to trust the Wikidata value, which to me makes it a certainty
qualifier.

Thanks, Peter,
I agree with You, I was wrong before. But also the stated as (P1932)
has certain info value
and both the stated as (P1932) and the determination method (P459) could
be additive ones.

Here is my breakdown of the top-10-by-usage qualifier predicates:
as of 13 July 2018
Label (ID) statements qualifiers
temporal qualifier point in time (P585) 336561 3147744
temporal qualifier start time (P580) 73298 1912311
temporal qualifier end time (P582) 54482 1236121
temporal qualifier valid in period (P1264) 67 656749
spatial qualifier chromosome (P1057) 128429 1397383
certainty qualifier? determination method (P459) 30 3407191
no information stated as (P1932) 3 667358
additive number of points scored (P1351) 1079 644273
additive number of matches played (P1350) 1507 628272
additive taxon author (P405) 0 463363

Hi Peter,
of the top ten qualifier properties by usage I find maybe just the stated as
(P1932) as contextual one.
Please, can You send examples of them of contextual and additive?

That does the trick, thanks.
I was trying to see how many uses of Wikidata qualifiers are contextual (i.e.,
give information about in which context the statement is valid) and which were
additive (i.e., do not limit where the statement is valid).
Of the top ten qualifier properties by usage, five are contextual, three are
additive, and one does not carry world information. The last can be
considered to be contextual, but also might be considered to not carry world
information.

I'm trying to get a good estimate of how
often which qualifier predicate is used.
The obvious query times out, as expected, so I was trying to find a list of
predicates that are used as qualifiers so that I can craft a query for each of
them. There is
https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.wiki…
but that can't be trusted as it doesn't include start time (P580) or end time
(P582) which I expect to be the most common qualifier predicates.
So, I'm stumped. Any suggestions?
