Abstract
Relevance Feedback (RF) algorithms were studied in the context of traditional IR systems where the returned unit is an entire document. In this paper we describe a component ranking algorithm for XML retrieval and show how to apply known RF algorithms from traditional IR on top of it to achieve Relevance Feedback for XML. We then give two examples of known RF algorithms and show results of applying them to our XML retrieval system in the INEX'04 RF Track. © Springer-Verlag Berlin Heidelberg 2005.
