This paper treats the problem of fuzzy query translation using the concept of database skeleton. An imprecise, or fuzzy, query is represented by a query graph, which can be analyzed for translatability with respect to a given database skeleton. The fuzzy query translation problem is formulated as a problem of converting a partially specified query graph into a completely specified query graph. This graph is then translated into a sequence of data manipulation commands, such as commands in relational algebra. Approaches to optimal fuzzy query translation are also described.
