Embodiment Construction

[0024] The mode of an implementation of the present invention is described below:

[0025] Using 12 SPARQL queries, the content of the query and the attributes specified in the query are shown in Table 1, and the attributes in a bracket are attributes of the same object.

[0026] The 12 SPARQL queries used in Table 1

[0027]

[0028]

[0029] Table 2-1 The 14 attributes and their numbers accessed by the query used in Table 1

[0030]

[0031] Table 2-2 The 14 attributes and their numbers accessed by the query used in Table 1 (continued)

[0032]

[0033] Table 3-1 The attribute connection matrix generated according to the 12 queries in Table 1 (1 indicates that the connection operation set corresponding to the i-th row has accessed the attribute corresponding to the j-th column)

Abstract

Provided is a dynamic RDF data conversion storage and attribute selection method. According to queries submitted by users, attributes are selected dynamically, a list structure is determined, and the list structure is optimized according to information related with connecting operations in the queries; the method comprises the steps that (1), RDF data query sets are inputted to generate corresponding attribute connecting condition matrices; (2), based on the attribute connecting condition matrices, attribute correlation degree matrices are generated; (3), the attribute correlation degree matrices are subjected to clustering; (4), according to affinity degree thresholds designated by the users, the clustered attribute correlation degree matrices are analyzed to execute attribute selection, and one or one ultimate attribute tables are formed. The query sets are inputted, so that the attribute connecting condition matrices are generated.

Description

technical field [0001] The invention provides a dynamic RDF (Resource Description Framework, resource description framework) data transfer and attribute selection method, and relates to the technical field of semantic web data storage. The technology provided by the invention can be used for RDF data management, can adapt to the requirements of different applications, achieves the effect of flexibly customizing dump strategies and improving query efficiency. Background technique [0002] Existing technologies provide the basis and reference for RDF (Data Resource Description Framework Data) storage, but due to the diversification of the application scenarios of the Semantic Web, different applications have very different access modes to RDF data, and various storage methods are used in different The performance under different access modes has its own advantages and disadvantages, so to achieve efficient storage, it is often necessary to design different storage strategies a...
