Report on the TREC 2003 Experiments Using Web Topic-Centric Link Analysis

In TREC 2003, our experiments have been concentrated only on the topic distillation task. We first simply apply the term-based technique to the .GOV web collection, and then re-rank the retrieval results using a link analysis algorithm in order to boost the retrieval precision. Our link analysis has been inspired from the original PageRank, but focused on the web topic during the iterative score propagation. We hybridize the term-based retrieval scores with our link analysis approach. From the experiments, the results show that the combination of those scores still provides inadequate precision improvement.
