We propose a novel index structure, the A-tree (Approximation tree), for the similarity search of high-dimensional data. The basic idea of the A-tree is the introduction of Virtual Bounding Rectangles (VBRs) which contain and approximate MBRs or data objects. VBRs can be represented rather compactly, and thus affect the tree configuration both quantitatively and qualitatively. First, since tree nodes can contain a large number of VBR entries, fanout becomes large, which leads to fast search. More importantly, we have a free hand in arranging MBRs and VBRs in tree nodes. In the A-trees, a node contains an MBR and its children VBRs. Therefore, by fetching a node of an A-tree, we can obtain the information of the exact position of a parent MBR...
