This paper describes the official measures of retrieval effectiveness that are employed for
the Ad Hoc Track at INEX 2007. Whereas in earlier years all, but only, XML elements could …

Since 2002, INEX has been working towards the goal of establishing an infrastructure, in the

We propose and evaluate a family of measures, the eXtended Cumulated Gain (XCG)
measures, for the evaluation of content-oriented XML retrieval approaches. Our aim is to …

Effectiveness is a primary concern in the information retrieval (IR) field. Various metrics for IR
effectiveness have been proposed in the past; we take into account all the 44 metrics we are …

In information retrieval research, comparing retrieval approaches requires test collections
