Dynamic ontology storage system, storage method and data query method

Abstract

The invention provides a dynamic ontology storage system, a storage method and a data query method. The ontology system comprises a source data storage layer, a configuration layer and an ontology storage layer. Source data configuration information, a dynamic ontology configuration rule and a dynamic ontology storage rule for configuring a target industry dynamic ontology can be dynamically generated according to user requirements and industry characteristics, and source data is acquired from a source data storage layer according to the source data configuration information. A dynamic ontology is generated by utilizing the obtained source data according to the dynamic ontology configuration rule, so that the configuration of ontology is more intelligent and flexible, meanwhile, a hybrid storage technology is adopted, a structured storage system is used as a main database for ontology storage, the safety and reliability of the ontology are effectively ensured, and the object relationship of the ontology is stored by a graph data storage system; the multi-level relationship of the objects in the ontology can be stored, the summary information of the ontology is stored by a full-textindex storage system, and more efficient query service can be provided for users.

Description

technical field [0001] The present application relates to the technical field of ontology storage, and in particular to a dynamic ontology storage system, a storage method, and a data query method. Background technique [0002] Ontology is a set of concepts or terms used to describe or express knowledge in a certain field and the relationship between these concepts or terms. It can be used to organize the knowledge abstraction at a higher level of the knowledge base, and can also be used to describe knowledge in a specific field . Ontologies are described by objects, object attributes, and object relationships. Among them, the object refers to any thing that can be modeled, the object attribute refers to some characteristic qualities of the object, and the object relationship refers to various relationships between objects. As a tool that can provide knowledge sharing and reuse at the knowledge level, ontology is currently widely used in the fields of semantic Web, informa...

Problems solved by technology

[0006] The first is that the storage of the ontology is not flexible enough. Generally, the schema of the ontology needs to be determined in advance before storing the ontology. Immobilized

The solidified ontology is based on fixed business requirements. Once the schema of the ontology is determined and then adjusted according to the business, the storage information of the entire set of ontology needs to be adjusted, which lacks sufficient scalability and flexibility.

[0007] In addition, using ElasticSearch for ontology storage, ES, as an in-memory search engine, has a memory bottleneck in large-scale data storage, and the lack of access control of data makes the stored ontology unsafe and reliable
