Weighted fuzzy queries in relational databases
Pages 430 - 441
Abstract
In most of fuzzy querying systems, items in query conditions are assumed to carry equal importance, although it might not actually to be the case. Issues for expressing users' preferences to query conditions are presented here. Relative importance between query items is introduced. Standard SQL is extended to express weighted fuzzy queries, such as sub-queries, multi-table queries; set-oriented queries etc. which make the existing relational database systems more flexible and more intelligent to users.
