MULTIDIMENSIONAL DATA OBJECT SEARCHING USING BIT VECTOR INDICES

摘要

Before the multidimensional feature space of search data object, each dimension in feature space is divided into several sections. It inquires if being removed, inquires the single section of overlapping, selected from each dimension. Then, selection only includes the data object of the section overlapping selected, and selects the set of data objects being cut in. Then, the set of the data object not instead of in feature space is whole, and the set of data objects being cut in using this determines the match to inquiry.
