SYSTEM AND METHOD FOR DATA BASE RETRIEVAL, DATA BASE REGISTERING DEVICE, DATA BASE RETRIEVING DEVICE, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To accurately grasp an occurring event not through an operator and to perform proper work, operation, or prediction corresponding to it. ;SOLUTION: A data input means 1 which inputs waveform data changing with time, a registering means 4 which registers data inputted in arbitrary timing among respective feature quantity data extracted from respective inputted waveform data in the form of a data base 5 while giving comments etc., and a retrieving means 6 which performs retrieval from the data base 5 by using feature quantity data as a key are provided and retrieved feature data is presented to an operator together with the comment as past access given thereto. Consequently, anybody can obtain the same result through retrieval based upon feature quantity data objectively representing the state of a retrieval object and also obtain necessary information from the comment etc.;COPYRIGHT: (C)1999,JPO
