چکیده

We describe a series of experiments conducted in our participation in the Relevance Feedback Track. We evaluate two traditional weighting models (BM25 and DFR) for the phase 1 task, which are widely used in text retrieval domain. We also evaluate a statistics-based feedback model and our proposed feedback model for the phase 2 task. Currently, we are waiting for the overview paper to facilitate further analyses.

RMIT University at TREC 2008: Relevance Feedback Track

This report outlines TREC-2008 Relevance Feedback Track experiments done at RMIT University. Relevance feedback in text retrieval systems is a process where a user gives explicit feedback on an initial set of retrieval results returned by a search system. For example, the user might mark some of the items as being relevant, or not relevant, to their current information need. This feedback can b...
