## 6.1 INEX Results 

The INEX XML Mining track is a collaborative evalu- ation forum where research teams improve approaches in supervised and unsupervised machine learning with XML documents. Participants make submissions and the evaluation results are later released. 

The RI K-tree in configuration E performs on aver- age at a comparable level to the best results submitted to the INEX 2008 XML Mining track. The top two results from the track had a micro purity of 0.49 and 0.50. These are not average scores for the approaches but the best results participants found. The RI K-tree in configuration E had a maximum micro entropy of 0.55. This is 10% greater than the INEX submissions.
