Embodiment Construction

[0018] In order to express the method of the present invention more clearly and intuitively, the present invention will be further described in detail below in conjunction with the accompanying drawings. The efficient distributed RDF data storage method of the present invention comprises the following steps:

[0019] 1) Data access, responsible for providing a unified data access interface to the outside world, and accessing data through the provided interface. It mainly includes interfaces such as data upload, data update, data query, predicate expansion and predicate information query.

[0020] 2) Data control, providing data control and processing functions mainly including data management, predicate management and data storage management.

[0021]Data management provides RDF data management functions, including RDF data upload, update and query control; RDF upload data control, including RDF data parser, RDF data segmentation module and unique ID generation. When data is...

Abstract

The invention discloses a high-efficiency distributed RDF data storage method. The method comprises the following steps that: 1) a user selects a named graph or sets a new named graph for each triple to be uploaded, and sets an effective predicate and a triple thereof for the triple according to service requirements; 2) a data control system analyzes each triple in the RDF uploaded by the user, extracts a predicate of the triple and the effective predicate of the named graph of the triple, and then splits the triple into two triples, namely the triple of a complete predicate of the same subject and the triple of the effective predicate of the same subject, with the same unique identifier according to the effective predicate, wherein the effective predicate is a part of predicate of the complete predicate; 3) the data control system respectively stores the triple data of the complete predicate of the same subject and the triple data of the effective predicate of the same subject to different database clusters. According to the high-efficiency distributed RDF data storage method, the high availability of data is improved.

Description

technical field [0001] The invention relates to the technical field of RDF data storage, in particular to an efficient distributed RDF data storage method, which belongs to the field of computer software. Background technique [0002] With the rapid development of Internet technology, the application scope of the Internet has become more and more extensive, and a huge knowledge network database has been formed, but it has also brought many challenges. In order to connect different forms of knowledge network databases, so that computers can understand The connection between data and data puts forward the concept of Semantic Web. The goal of the Semantic Web is to make the information resources on the network understandable by machines, so as to realize the automatic processing of network information resources and adapt to the rapid growth of network information resources. [0003] The Semantic Web defines a resource description framework, RDF, to describe information resourc...
