In this paper, we report on the experiments we conducted whilst participating in the TREC 2013 Web track. We use data fusion to test how to improve the results from different information retrieval systems. Linear combination is used for fusion and multiple linear regression is used to obtain suitable weights for all the component systems involved. In our(More)
