Hello Lorenz,

Thank you again for your answer. I wish you a happy new year. I am sorry 
to disturb you again with some new questions…

1. Is there a parameter to display more than the 10 first best 
solutions? For example, to display all the solutions with the same 
accuracy and f-measure as the first solution.


2. What is the criteria for the order of the answers (besides accuracy 
and f-measure)?
If there are several solutions with the same accuracy/f-measure, how do 
you choose what solution to put in the first position?
I think it is related to the readability, but could you explain a bit 
more please?

I am asking this because I am confused with 2 things:

- If I take the “hasCulture min 6 Thing” with the parameters you have 
added: the second solution is “hasCulture min 6 (not WaterBody)” and the 
next ones are all like “hasCulture min 6 (not Concept_Name)”. I don’t 
understand why “hasCulture min 6 Culture” is not at least in the second 
position. I mean, “Culture” is more readable than “(not Concept_name)”, 
isn’t it?

- Moreover, in this context, “hasCulture min 6 Culture” and “hasCulture 
min 6 Thing” are equivalent because Culture is the range of hasCulture. 
But in my opinion, it would be more adapted to get “hasCulture min 6 
Culture” before “hasCulture min 6 Thing”. I mean, I would rather say to 
an expert that a cultural destination is a destination which hasCulture 
at least “6 instances of Culture” rather than “6 instances of Thing”. Of 
course, this is only a matter of readability for an expert, since saying 
“Thing” or “Culture” does not change anything if the ontology is 
consistent.


3. Is there a way to avoid to get solutions with the same 
accuracy/f-measure as one solution but which are much more complex for 
no reason?

For example, if I disable the “not” and “only” with the “hasCulture min 
6 Thing” example, I get:
1: hasCulture min 6 Thing
2: Destination and hasCulture min 6 Thing
3: hasCulture min 6 Thing and (Destination or Weather)
4: hasCulture min 6 Thing and (Destination or Season)
Etc

All of these definitions are 100% correct.
But what is the point to get the “or Weather” / “or Season” part? If I 
say “hasCulture min 6 Thing and (Destination or ConceptA or ConceptB or 
…)”, of course I can add anything with “or”, it would not change the 
accuracy but I don’t see the point.


Thanks a lot,
Céline
