Topic on User talk:Swpb

Hi. Your message is not entirely clear to me - could you detailed explain " Errors with basic membership properties create false inferences." ? Maybe some examples. Thanks. ~~~~

There is an example right in my message: brewery (Q131734)subclass of (P279)action (Q4026292). Clearly, a brewery is not a kind of action ("brewing" is not the same as "brewery") - but that is what is implied by your edit. Another false inference is Giger Bar, Chur (Q16910525)instance of (P31)action (Q4026292). The property subclass of (P279) is a transitive Wikidata property (Q18647515). That means if A is a subclass (or instance) of B, and B is a subclass of C, then it can be inferred (assumed) that A is a subclass (or instance) of C, and lots of tools rely on that assumption being correct. This transitivity creates complicated chains of inference, like this one: . If one link in that chain is incorrect, everything above it will be incorrect as well. In fact, there are nearly 4000 items for types of businesses, and tens/hundreds of thousands of items for individual businesses, that all incorrectly become "actions" because of your edit. So I would suggest that if you don't entirely understand what the basic membership properties mean, you avoid using them.

Also, by the way, it's usually best to respond to messages where they are - meaning your talk page, not mine. If you'd replied there, I would have been notified.

Real problem is in definition of economic activity because it should not be defined as an action, but simpler is make undo of my changes, so i'll do it. Business is an economic activity from the science point of view. There is a lot of problems in base definitions in WikiData.

I already undid your change. economic activity (Q8187769), on the other hand, is properly a subclass of action activity; there is no problem there. You are confusing the activity of operating a business with the organization that is the business (Q4830453) itself, which is absolutely not an activity. It helps to read the descriptions of items before you use them in statements; the descriptions of business (Q4830453) make this clear. Swpb (talk) 14:51, 16 May 2024 (UTC)

It has no logic. It's not an action - it's an activity. It causes problems like this. Action it's a single event but activity is continuos.

While that's true, your edit only made the problem worse. intentional human activity (Q451967)subclass of (P279)action (Q4026292) was arguably wrong, and I've removed that statement. But that's not what made thousands of businesses into activities. Take my original comment and replace action (Q4026292) with intentional human activity (Q451967), and the problem stands.

It's not so simply ... right now we have problem with linked links to Wikipedia articles and some translations.

If translations are wrong, you can fix them; if Wikipedia articles are linked to the wrong item, you can move them. None of that justifies adding a false statement. It doesn't bother me when someone makes a mistake, but it does when they won't acknowledge it, since it suggests they'd make that mistake again.

I just informed you about problems. You can make some more changes or leave it ... i'm not interested in.
