SYSTEM OF ENTITY-RELATIONSHIP MODEL REFORMULATION OF SPARQL QUERY RESULTS ON RDF DATA AND THE METHOD

摘要

The present invention relates to a kind of system and method for the object relationship pressure SPARQL query results for RDF data,Particularly,One object uses the ontology scheme information SPARQL query results for having directive SPARQL query results -- by the result of the effectively SPARQL inquiries of the map object to a relational model concept element in upper RDF data that can will be tensed by the relational system between range estimation strain and coming be used for it is corresponding from the query condition of XML/RDF Database Systems in SPARQL inquiries with variable according to one query graph of relationship and query result of the objective system SPARQL query results of RDF data of the invention,It is used to manage data as RDF ontologys shape format and to the query result extraction module of extract; Type electricity generation module generates certain query result and the framework using query graph, and the query result extracted by extraction module, query resu Quantification, parent-child heredity corresponding with the relationship of type generated by electricity generation module type, by being executed on entity type between object-relational model and saengseongneun heredity modules and relationship; In the hereditary number of modules from corresponding relational model 1, object create: a kind of relationship and model reduction module of merged entity type and have a predetermined relationship; Query result in that is comprising: which a visualization module has its feature for estimating the concept pressing map element and sorting out.
