Inferring participation when using orgs as participants #8

Open nickdrummond opened 2 years ago

nickdrummond commented 2 years ago

How do we infer that specific people were participants in Evacuation_of_Garel - we're using Spectres a lot?

Should we say that all members of an organisation or crew were at that event? What about Battles - Rebel Alliance vs Empire?

Not all members of a group are a member at that time.

How do we say "all members of Spectres" - can't without cardinality (which cannot be used on transitive memberOf?

Can we say: participant some ((memberOf value Spectres) and (not{Kanan_Jarrus}))

not{Kanan_Jarrus} takes an eternity in DLQuery

nickdrummond commented 2 years ago

But "at least one" member will not give us the inference we want

nickdrummond commented 2 years ago

Adding more nominals and qualified cardinality restrictions is just going to cause problems with pellet. Best to simply enumerate the individuals we are interested in.

Replace Spectres in all these http://localhost:8080/dlquery/?expression=included+some+%28participant+value+Spectres%29&minus=&syntax=man&order=&query=instances

Still leaves us with issues when using "Crew"s:

Defecting_pilots is not included in the query participant value Ezra_Bridger

nickdrummond commented 1 year ago

Another way:

New property participantsFrom range = Organisation

Property chain participantsFrom o hadMember -> participant

Would need versions for all participation properties - eg of = Escape ofAllMembersOf Spectres ? And a prop chain for each or at least a mirror property hierarchy.

THis also works for the Crew problem.

Not clear what the classification and query overhead is yet
