Hi Amir, Aleksander
this could be fixed in the DBpedia mappings.
The Monty Python wikipedia articles is using the Infobox_comedian [1] which
is defined also for Comedy groups.
The problem is that the mapping [2] maps only to the Comedian class, while
it should use a ConditionalMapping, as done for the Infobox_musical_artist
[3]
In order to fix this I think we should:
1) Create a ComedyGroup class, which is a rdfs:subClassOf Organisation
2) Add a ConditionalMapping in [1] that maps to ComedyGroup in case
current_members or past_members is set
I am going to do this is a while.
Cheers
