Created page with "==Countries on EN DBpedia== select count(*) { ?country a dbo:Country} returns 1694 countries. Obviously this won't do. Let's analyze the reasons for this pollution and try..."

New page

==Countries on EN DBpedia==
select count(*) {
?country a dbo:Country}
returns 1694 countries. Obviously this won't do.

Let's analyze the reasons for this pollution and try to fix it.

==Countries on EN Wikipedia==
There are [https://en.wikipedia.org/w/index.php?title=Special%3AWhatLinksHere&limit=5000&target=Template%3AInfobox+country&namespace=0 638 Infobox_country instances].
Most of them are international organizations (free trade zones, unions, etc).
On the other hand, [https://tools.wmflabs.org/templatecount/index.php?lang=en&name=Infobox_country&namespace=10#bottom transclusion count] says 1137.

[http://dispenser.homenet.org/~dispenser/cgi-bin/rdcheck.py?page=Template:Infobox_country The following templates redirect to Template:Infobox country]:
* Template:Infobox Countries
* Template:Infobox Country
* Template:Infobox Country or territory
* Template:Infobox Geopolitical organisation
* Template:Infobox Geopolitical organization
* Template:Infobox Micronation
* Template:Infobox geopolitical organisation
* Template:Infobox geopolitical organization
* Template:Infobox micronation
* Template:Infobox nation
DBpedia works only with the target template (Infobox_country), so these redirects are not a problem.

== Analysis Needed ==
* Why are there more dbo:Country in DBpedia than "Infobox country" in Wikipedia?
* Why "transclusion count" shows more than uses of "Infobox country"
* Many pages have a "type" that allows us to map to a better class (eg https://en.wikipedia.org/wiki/Eurasian_Economic_Space has Type "Single market"). Eg [https://github.com/dbpedia/extraction-framework/issues/296 #296] "Why Infobox_Geopolitical_organization (eg United_Nations) is mapped to Country" is resolved in this way.
* But many other instances remain, eg United_Nations_Transitional_Authority_in_Cambodia: analyze and see if there's some other discriminator than "type"
* How to filter out the sports organziations, eg Cricket_Samoa, IBA_Asia, Great_Britain_men%27s_national_basketball_team?
* How about country-related articles, eg Radio_in_the_United_States, Human_trafficking_in_the_United_States, History_of_the_Jews_in_20th-century_Poland?
* How about articles that are not even country-related, eg Comic_book_collecting, Record_collecting?
* How about admin locations (eg cities) that are not countries, eg Russian_Dalian?
* How about non-administrative locations, eg Reñaca_beach?

===Infobox national basketball team===
Great_Britain_men%27s_national_basketball_team uses template Infobox national basketball team that is not mapped in the wiki.
But why does it come out as dbo:Country?
