<p>PROBLEM TO BE SOLVED: To provide a database automatic generation device for making it possible to generate an accurate database while enabling increase in processing speed and improvement of accuracy in cluster analysis.SOLUTION: A database automatic generation device comprises: arithmetic processing means for calculating feature quantity data unique to a feature vector waveform; data sorting means for sorting the feature quantity data; dendrogram generation means for generating a dendrogram by analysing the feature quantity data sorted by the data sorting means, by using a hierarchical cluster analysis method; and determination means which returns feature quantity data of a feature vector waveform corresponding to a cluster whose internal dispersion is larger than a threshold of clusters generated on the basis of the dendrogram to the data sorting means, and registers data related to a feature vector waveform corresponding to a cluster whose internal dispersion is equal to or smaller than the threshold to a database.</p> |
