Predicting the performance of linearly combined IR systems

Christopher C. Vogt, Garrison W. Cottrell
1998 Proceedings of the 21st annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '98  
We achieve this by using a linear regression to accurately (T ' = 0.98) predict the performance of the combined system based on quantitative measurements of individual component systems taken from TREC5  ...  We introduce a new technique for analyzing combination models. The technique allows us to make qualitative conclusions about which IR systems should be combined.  ...  Thanks go to Matt Dailey and the rest of GURU for their useful comments.  ...
