SYSTEM, APPARATUS, PROGRAM AND METHOD FOR DATA AGGREGATIONE

摘要

Embodiments include a method, apparatus, program, and system for distributing data items among a plurality of data storage units, the data items being an aggregation of data from a plurality of data sources. The method comprises generating a semantic description of each of the plurality of data sources; calculating, for each pair of data sources from among the plurality of data sources, a degree of similarity between the semantic descriptions of the pair of data sources; and allocating data items to data storage units in dependence upon the calculated degree of similarity between the data source of a data item being allocated and the or each data source of data items already allocated to the data storage units.

1. A method for distributing data items among a plurality of data storage units, the data items being an aggregation of data from a plurality of data sources, the method comprising:
generating a semantic description of each of the plurality of data sources; calculating, for each pair of data sources from among the plurality of data sources, a degree of similarity between semantic descriptions of the pair of data sources; and allocating data items to data storage units in dependence upon the degree of similarity between the data source of a data item being allocated and one of the and each data source of data items already allocated to the data storage units.
