DATA BANK, METHOD OF DERIVING A DATA BANK, AND METHOD OF QUERYING A DATA BANK

摘要

A data bank in accordance with the invention can be queried by means of linguistically unclear terme. Since the meaning of linguistically unclear terms depends on the context in which they are used, each data set in the data bank contains associative values for the linguistically unclear terms, which indicate to what relative degree a respective linguistic value coincides with the corresponding data set as compared to the other data sets. The data bank is derived from the first data sets and contains for each first data set a corresponding second data set in which the associative values are stored. In addition a method of querying such a data bank is indicated, and a method of deriving such a data bank from the first data sets by using the rules of the fuzzy logic theory.
