Abstract

The invention provides a R2RML standard-based mapping method, a device, equipment and a storage medium. The method comprises the following steps: determining a mapping task from a relational databasebased on the R2RML standard created by a user to a resource description framework, and connecting the relational database indicated by the mapping task; performing explicit structural feature, data feature and implicit semantic analysis on the relational database to obtain an association relationship table of the relational database; determining a target mapping mode selected by a user from at least one preset mapping mode; and performing RDF triad definition by utilizing the target mapping mode and the association relationship table, automatically generating an R2RML mapping document based onthe R2RML mapping rule, and further generating an RDF triad file according to the R2RML mapping document. According to the method, the R2RML mapping document can be automatically generated, and automatic generation of the RDF triple file is realized.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, relates to a mapping method, device, equipment and storage medium based on the R2RML standard. Background technique [0002] With the continuous development of science and technology, there are more and more mapping conversion tools for mapping relational databases to resource description frameworks, such as DB2Triple, Morph-RDB, R2RML Parser, Virtuoso Universal Server, XSPARQL, Ontop, SparqlMap, Sparqlify, GeoTriples, R2RML-kit. These mapping conversion tools mainly map relational databases to resource description frameworks by focusing on the parsing and mapping execution of R2RML mapping rules. [0003] However, in the actual use of mapping conversion tools, existing mapping conversion tools lack the functions of relational database schema analysis and implicit semantic discovery; they lack easy-to-understand and effective mapping definition methods, and exist...
