G-tridiagonal majorization on
For , it is said that is g-tridiagonal majorized by (and it is denoted by ) if there exists a tridiagonal g-doubly stochastic matrix such that . In this paper, the linear preservers and strong linear preservers of are characterized on .
Guided Local Search for query reformulation using weight propagation
A new technique for query reformulation that assesses the relevance of retrieved documents using weight propagation is proposed. The technique uses a Guided Local Search (GLS) in conjunction with the latent semantic indexing model (to semantically cluster documents together) and Lexical Matching (LM). The GLS algorithm is used to construct a minimum spanning tree that is later employed in the reformulation process. The computations done for Singular Value Decomposition (SVD), LM and the minimum...
