INFORMATION PROCESSING DEVICE
First Claim
1. An information processing device comprising:
- an index generating unit for generating index data that are distributedly stored into a plurality of servers, respectively, each of the index data being generated for each of data point information including metadata representing a characteristic of data to be searched, and each of the index data being associated with reference point information that are others of the data point information such that distances to the each data point information based on a previously set reference are within a previously set range; and
a communication cost storing unit for storing, for each of the servers storing the respective index data, communication cost information representing a previously set cost that costs in communication with the server,wherein the index generating unit is configured to select the reference point information to be associated with specific one of the data point information, based on the communication cost information of the server storing the index data corresponding to the reference point information.

Abstract
An information processing device of the present invention includes: an index generating means for generating index data distributedly stored into a plurality of servers, each index data being generated for each data point information including metadata representing a characteristic of data to be searched, and each index data being associated with reference point information that are other data point information such that distances to the each data point information based on a preset reference are within a preset range; and a communication cost storing means for storing, for each of the servers storing the index data, communication cost information representing a preset cost that costs in communication with the server. The index generating means selects the reference point information to be associated with specific one of the data point information, based on the communication cost information of the server storing the index data corresponding to the reference point information.

8. A non-transitory computer-readable medium storing a computer program comprising instructions for:
-
causing an information processing device to realize an index generating unit, wherein the information processing device includes a communication cost storing unit for storing, for each of servers storing respective index data, communication cost information representing a previously set cost that costs in communication with the server, and the index generating unit is a unit for generating index data that are distributedly stored into a plurality of servers, respectively, each of the index data being generated for each of data point information including metadata representing a characteristic of data to be searched, and each of the index data being associated with reference point information that are others of the data point information such that distances to the each of the data point information based on a previously set reference are within a previously set range; and causing the index generating unit to select the reference point information to be associated with specific one of the data point information, based on the communication cost information of the server storing the index data corresponding to the reference point information.

9. An information processing method in an information processing device including a communication cost storing unit for storing, for each of servers storing index data, communication cost information representing a previously set cost that costs in communication with the server, the information processing method comprising:
when generating index data that are distributedly stored into a plurality of servers, respectively, each of the index data being generated for each of data point information including metadata representing a characteristic of data to be searched, and each of the index data being associated with reference point information that are others of the data point information such that distances to the each of the data point information based on a previously set reference are within a previously set range, selecting the reference point information to be associated with specific one of the data point information, based on the communication cost information of the server storing the index data corresponding to the reference point information. - View Dependent Claims (10)
