APPARATUS AND METHOD FOR CONSTRUCTING DATA AND APPARATUS AND METHOD FOR RETRIEVING DATA INCLUDING NON-SPATIAL INFORMATION

摘要

PURPOSE: An apparatus and a method for constructing data and an apparatus and a method for retrieving data including non-spatial information are provided to search documents quickly by generating an index tree and an index bucket including data bucket and address information of data bucket which includes position information and aspatial information of a data object. CONSTITUTION: A data bucket generating unit(110) creates data bucket including the aspatial information. An index tree generating unit(120) creates an index tree by hierarchically arranging a terminal node and a nonterminal node. An index bucket generating unit(130) creates the index bucket including the terminal node information and the index bucket including the nonterminal node information and the address information. A multiplexer(140) creates encoded data. A time information output unit(150) changes the address information of the index bucket and data bucket based on the transfer rate of the encoded data into the time information.
