Re: [emf-dev] EMF Compare - Compare multiple Models for Pattern Mining purposes

Hey Cédric,

thanks for your quick reply. I think there are several (possible) strategies but with respect to the computation time only a few might be practicable.
Hopefully i can provide some results soon, especially as you mentioned your interest. Perhaps we could discuss some aspects in a skype session?
If you are interested just tell me so we can schedule the session.

Kind Regards,

Hi Tobias,

The  Compare component is able  to compute delta from 2 versions of a model +an optional common ancestor.

I'm not aware of any specific strategy used to compare "n" models with each others one strategy could be to determine first a  "reference model" and then compare all the others with this one, another could be to compare every combination of model and then compare their own diffs... It really is an open question especially if you want to do something which is sustainable from a computation complexity perspective.

That said I'm would be quite interested in the outcome of your reflexion, feel free to send me a note then ;)

my name is Tobi. I'm currently working on my Master Thesis. I would like to use EMF Compare to find frequent patterns in Ecore-based models. I know that EMF Compare provides cababilities to compare two models (left and right side) but in my case it is necessary to compare multiple models in order to find the frequent patterns in a certain scope. Therefore i'm wondering if there are known strategies to reach the described goal. Any ideas?

Thanks in advance.
