Multistage intelligent database search method |
摘要 |
An improved multistage intelligent database search method includes (1) a prefilter that uses a precomputed index to compute a list of most "promising" records that serves as input to the original multistage search method, resulting in dramatically faster response time; (2) a revised polygraph weighting scheme correcting an erroneous weighting scheme in the original method; (3) a method for providing visualization of character matching strength to users using the bipartite graphs computed by the multistage method; (4) a technique for complementing direct search of textual data with search of a phonetic version of the same data, in such a way that the results can be combined; and (5) several smaller improvements that further refine search quality, deal more effectively with multilingual data and Asian character sets, and make the multistage method a practical and more efficient technique for searching document repositories.
