Method and apparatus for generating text corpus by using knowledge graph

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program, which when executed by a processor causes the processor to:

• read graph data and ontology information of a subgraph in the knowledge graph, wherein the graph data comprises several triplets comprising graph elements in the subgraph, and the ontology information comprises at least a type of each graph element in the subgraph;
• generate several sentences based on several pre-constructed sentence templates, the graph data, and the ontology information, wherein the several sentences are classified into a generated sentence set, and at least one of the several sentence templates is constructed based on the ontology information;
• and
• determine a text corpus corresponding to the subgraph based on the generated sentence set, wherein the text corpus is used to train a language model.

A computing device, comprising a memory and a processor, wherein the memory stores executable code, and when the processor executes the executable code, the computing device is caused to:

• read graph data and ontology information of a subgraph in the knowledge graph, wherein the graph data comprises several triplets comprising graph elements in the subgraph, and the ontology information comprises at least a type of each graph element in the subgraph;
• generate several sentences based on several pre-constructed sentence templates, the graph data, and the ontology information, wherein the several sentences are classified into a generated sentence set, and at least one of the several sentence templates is constructed based on the ontology information;
• and
• determine a text corpus corresponding to the subgraph based on the generated sentence set, wherein the text corpus is used to train a language model.
