Abstract

The embodiment of the invention discloses a semantic data storage and retrieval method and device based on a maximum regional grid, relates to the technical field of databases, and can improve semantic-based query efficiency. The method comprises the steps of extracting semantic entities from semantic data to be processed, and performing data encoding on the semantic entities to obtain a semanticgraph; carrying out maximum grid search mining by utilizing the obtained semantic graph, obtaining a set of entity vertexes containing a maximum connected grid, and obtaining an index of the maximum connected grid according to the set; performing clustering processing on the entity vertexes in the maximum area grid, wherein the clustering result comprises an inter-cluster relation table, a clusterdescription table and a cluster center vertex table; and processing a retrieval request by utilizing the clustering result. The method and the device are suitable for semantic data query.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a method and device for storing and retrieving semantic data based on a maximum area grid. Background technique [0002] In traditional relational databases, there are many shortcomings in semantic data storage, such as many fields, high coupling, complex association, high redundancy, and responsible query and retrieval. The knowledge map is an efficient information relationship organization and management method. It has the advantages of focusing on semantic expression, machine comprehension, clear association, low redundancy, efficient query, and dynamic change of data patterns. Structured and semi-structured multi-source heterogeneous information is separated from islands and organically integrated, which not only improves the application performance to meet actual needs, but also obtains more value-added capabilities. Specifically, it includes semantic understanding, intel...
