RDF DATA DISTRIBUTED PARTITIONING METHOD AND SYSTEM USING CLUSTERING ALGORITHM

摘要

The RDF data distribution partitioning method of the present invention comprises the steps of: analyzing an RDF data set to form a property-type bitmap; generating type-properties by applying the property-type bitmap to an input query set; clustering the type-properties; and distributing and storing the RDF data set according to the clustering result. Here, the RDF data set includes meter data including a timestamp as data collected from a smart meter, master data including basic information about users and devices that are the subject of meter data, meter data and master data. Each unit data of statistical data representing the data-based online batch analysis result may be a set of three triples of a subject, a predicate, and an object.
