Embodiment 1

[0058] This embodiment provides a data acquisition method of an ontology database.

[0059] figure 1 A flow chart of a data acquisition method for an ontology library provided in this embodiment, such as figure 1 As shown, the method mainly includes the following steps S102 to S104.

[0060] In step S102, based on ontology configuration information, import ontology-related data from at least one external data source into a column-stored distributed database to obtain ontology data of one or more ontology instances; wherein, in the distributed database In , ontology data of the same ontology instance from different external data sources are associated based on ontology instance identification.

[0061] In an optional implementation of this embodiment, the ontology configuration information includes, but is not limited to: identification information of at least one external data source, mapping relationship between preset data fields in the external data source and attribute f...

Embodiment 2

[0121] Based on the same idea as that in Embodiment 1, the present application also provides a device for writing ontology database data, which can be used to implement the method for writing ontology database data provided in Embodiment 1.

[0122] Figure 16 It is a schematic structural diagram of a data writing device for an ontology library provided by this application, such as Figure 16 As shown, the device mainly includes: an import module 1610 and a write module 1620 . The following mainly describes the functions of the functional modules of the data writing device of the ontology library provided by this embodiment. For other related matters, please refer to the description of Embodiment 1, which will not be repeated here.

[0123] In this embodiment, the import module 1610 is configured to import ontology-related data from at least one external data source into a column-stored distributed database based on ontology configuration information, and obtain ontology dat...

Abstract

The invention discloses a data writing method and device for an ontology library. The method comprises the following steps: importing ontology related data in at least one external data source into adistributed database stored in a column mode based on ontology configuration information, and obtaining ontology data of one or more ontology examples; wherein in the distributed database, ontology data of the same ontology instance from different external data sources is associated based on an ontology instance identifier; and aggregating the ontology data of the same ontology instance stored inthe distributed database based on the ontology instance identifier, and writing the ontology data into an ontology library.

Description

technical field [0001] This application relates to the field of computer technology, in particular to a method and device for writing data into an ontology database. Background technique [0002] At present, with the development of the Internet, a large amount of information floods into people's sight, how to store these massive data so that people can find the information they need is a problem that needs to be solved. [0003] In related technologies, a solution to the above problems is to store data in a relational database. The relational database can store structured data well and store relationships between entities, while supporting structured queries. However, for complex relationships, using relational databases for storage is more difficult in designing data tables, and it is easy to cause data redundancy. [0004] Ontology is a concept derived from philosophy, which is borrowed by knowledge engineering scholars to acquire domain knowledge when developing knowledg...
