Our main finding is that redundancy-based ideas in combination with naively learned stream weights conditioned on question type work best, and improve significantly over a number of baselines.

Our evaluation shows that precision in the top ranks of this technique is higher than for the existing resource selection methods for long queries and lower for short queries; on average the combined approach outperforms CORI and the other DTF variants.

Experimental results show that the high-degree biased bigrams should be eliminated from the feature set, and the .-BR1 scheme is quite effective for further dimensionality reduction in Chinese text categorization, after a feature selection process with a .???. score function.

S. A. Müller-Lissner,L. M. A. Akkermansly useful for cross language retrieval where problems during translation can result in a poor initial ranked list with few relevant in the top .. We find that the number of feedback documents and the influence of the initial query on the feedback model most affect retrieval performance.
