Upcoming feature of SPMF 2.63: Taxonomy Viewer

Today, I want to share briefly a new feature of the upcoming SPMF version 2.63, which is the taxonomy viewer. This tools allow to visualize a taxonomy used by algorithms such as CLH-Miner and FEACP.

The user interface is for now quite simple and looks like this:

In this example, I display a file called transaction_CLHMiner.txt, which defines the taxonomy:

1,6
2,6
3,7
4,8
5,8
6,7
9,1
10,1

And a transaction database given names to these items in a file taxonomy_CLHMiner.txt:

@ITEM=1=apple
@ITEM=2=orange
@ITEM=3=milk
@ITEM=4=bread
@ITEM=5=bagel
@ITEM=6=orange
@ITEM=7=FreshProducts
@ITEM=8=BreadProducts
@ITEM=9=red_apple
@ITEM=10=green_apple
1 3:6:5 1
5:3:3
1 2 3 4 5:25:5 10 1 6 3
2 3 4 5:20:8 3 6 3
1 3 4:8:5 1 2
1 3 5:22:10 6 6
2 3 5:9:4 2 3

This is just to give you a preview of some new features of SPMF. The next version should be released in about 1 week!
