Hoi,
A category or a list includes entries that fulfill certain criteria. For
instance,many awards are given to humans, so we can define on the list "is
a list of" "human"with a qualifier "award received" "Award
name". Over 1400
categories have such definitions [1]. When you choose any of them, there is
an icon for the "Reasonator". It shows up to 500 items that fit the
definition independent if they are on one, all or no categories.
The Reasonator will show up to 500 people on the award. It will show the
award on the person and, it will show the first 500 items that fit the
query defitinition and all others may be shown in.
I am actively harvesting categories in this way and, I do this based on the
content of categories on many Wikipedias. As a result at least half a
million statements have been made as a result, probably a lot more.
What will be of real interest to you is that for all those 1400 categories
the entries will show in the Reasonator. When there are more than 500,
there is an option to see all of them in a differrent screen.
Thanks,
GerardM

Hello,
[think this come up before, but can't find a recent thread that directly
relates to this]
Are there any plans directly relate entities in Wikidata with categories
in Wikidata – and avoid the duplication between all the different page
languages?
For example this book:
http://www.wikidata.org/wiki/Q3235393
<https://www.wikidata.org/wiki/Q3235393>
http://en.wikipedia.org/wiki/Half_of_a_Yellow_Sun
<https://en.wikipedia.org/wiki/Half_of_a_Yellow_Sun>
And the English Wikipedia page is a member of this category:
http://en.wikipedia.org/wiki/Category:War_novels
<https://en.wikipedia.org/wiki/Category:War_novels>
Which has this Wikidata ID associated with it:
http://www.wikidata.org/wiki/Q8170055
<https://www.wikidata.org/wiki/Q8170055>
Currently we could resolve it using the following, slightly convoluted
workflow:
1. Get Wikidata ID and resolve to 1 (or more) Wikipedia language pages
2. For each Wikipedia page, lookup a list of categories and gather
together
3. From each category lookup a Wikidata ID for that category page
4. Remove duplicate Wikidata IDs
5. Lookup each of the Wikidata IDs in Wikidata to get title/description
Going from a Wikidata Category to a list of Wikidata entities could be
done in a similar way.
Is there a better way of doing this now or the near future?
