Document Type and Number:
Japanese Patent JP6183376
Kind Code:
B2
Abstract:
An index generating device (100) comprises: an index generating unit (101) which uses an interdata similarity degree which is computed by a similarity computation unit (105) to generate an index which includes a lower order node, and a higher order node which includes an entry having a link relation with the lower order node and indicating representative data having a similarity degree with data indicated by an entry in the lower order node greater than or equal to a similarity threshold value appended to the link relation; and a threshold setting unit (102) which sets the similarity threshold to a value which increases the further down the hierarchy.
