Ranking Data Sources in a Data Processing System

摘要

A computer-implemented method for provision of data according to a ranking is provided. The method includes establishing an analytical representation of an arrangement of data entities, data sources and network relationships in a computer network; establishing a rule schema for ranking a data entity, a data source and a network relationship according to ranking criteria; storing the rule schema in association with the analytical representation; receiving a request for data, from a data consumer, specifying requested ranking metadata; receiving at least a segment of a data stream; executing a rules engine to apply the stored rule schema to the segment to classify the segment by linking associated ranking metadata with the segment; responsive to the associated ranking metadata matching the requested ranking metadata, populating an output data structure from data in the segment; and transmitting the populated output data structure to the data consumer.
