Abstract

We present a Retrieval Information system for XML documents using a Machine Learning Ranking approach. We then propose a way to annotate and build a training set for our learning to rank algorithm OWPC [1]. Finally, we apply our algorithm to the INEX'09 collection and present the results we obtained.
