Title: | The optimal size of a signature | Authors: | Sung, S.Y. Hsu, W.J. |
Keywords: | Database Information retrieval Performance evaluation Signature file Superimposed coding |
Issue Date: | Feb-1995 | Citation: | Sung, S.Y.,Hsu, W.J. (1995-02). The optimal size of a signature. Mathematical and Computer Modelling 21 (4) : 67-75. ScholarBank@NUS Repository. | Abstract: | Signature file has been shown to be a fairly good filtering mechanism to reduce the amount of data that need to be retrieved for a query. Previous work in signature construction has emphasized on determining the optimal signature weight to minimize the false drop probability. In this paper, we present a method to determine the optimal signature size to a block according to its bit probability and the number of objects in that block. The scheme is optimal for both uniform and nonuniform block accessing frequencies. © 1995. | Source Title: | Mathematical and Computer Modelling | URI: | http://scholarbank.nus.edu.sg/handle/10635/99438 | ISSN: | 08957177 |
