Abstract
The present invention provides an information processing apparatus for clustering a plurality of pieces of data in clusters corresponding respectively to nodes on layers in a tree structure by assigning each of the pieces of data to a leaf node of the tree structure. The information processing apparatus includes: metadata acquisition means for acquiring metadata of the pieces of data; and tree-structure processing means for finding a first distance and a second distance on the basis of the metadata and adding a new node to the tree structure on the basis of the first and second distances as a node having an attention node, which is assigned to attention data placed at an attention-receiving position in an array of the pieces of data arranged on the basis of the metadata of the pieces of data, as a child node.
