Hi!
I know some of you are working on DSM-kind of matrix. Oscar has been working on a similarity matrix for Roassal. I just want to share a self-explanble screenshot with you guys.
On this example, the methods of the subclasses of Set are compared between themselves. Black dot is a couple (m1, m2) that are very similar

Cheers, Alexandre
Really nice. In fact it would be ****great**** if we can plug the comparison between the x and y cells (which can be different). Because like that we get a simple matrix based comparator similar to the one of early paper of prejinshight work.

This is the case actually.
Consider this rather simple and small example: SimilarityMatrix new on: #('hello world' 'welcome to our world' 'hello means bonjour' 'bye bye') by: [ :m1 : m2 | (m1 substrings intersection: m2 substrings) size / ((1 max: (m1 substrings union: m2 substrings) size) + 1) "NB penalty for small methods" ]; gridView
The output is
It visually says that ‘hello world’ is close to ‘welcome to out world’ and to ‘hello means bonjour’, because ‘hello’ and ‘world’ are in common.
Alexandre
then this is really cool
:)
