In search, for the query of “best game in the history”, documents about “most popular game”, “hardest game” and “strongest game” are promoted to higher positions, which enhances the relevance as well as the richness of search result. However, there are also some bad cases, mainly due to noises in the synonym dictionary. For example, in one experiment our mining algorithm identifies “google” and “baidu” as synonyms. Then for the query of “google map”, a document about “baidu map” is ranked higher than a document about “google earth”.

Consequently, all rows of Lx will converge to the eigenvector (with the largest eigenvalue) of the matrix (λ2 ρ2 )−1 CC T , and so will be all rows of Ly . Thus, the optimal parameters L∗x and L∗y are both matrices of rank one. This justifies the necessity of regularization on the matching matrix LTx Ly . 2 Incorporating Semantic Knowledge to Latent Matching Model A latent matching model trained with the method described in the previous section can perform well for head queries and documents, since it can capture the matching information from click-through data.

Other unnormalised measures such as Time-Biased Gain [13], U-measure [6] and those designed for diversified search may be handled similarly. Furthermore, we have demonstrated that discrete measures such as nG@1, which clearly violate the normality assumptions, can be “smoothed” to some extent by applying std-AB. Recall that topic set size design assumes The Effect of Score Standardisation on Topic Set Size Design 27 that the scores are indepent and identically distributed: that the scores for system i obey N (μi , σ 2 ).
