To import triple data in bulk to Neo4j, you can follow these steps:

  1. Prepare the data file: Save the triple data in a file, with each triple occupying one line and using commas, tabs, or spaces to separate the subject, relationship, and object. For example:
主体1,关系1,客体1
主体2,关系2,客体2
主体3,关系3,客体3
...
  1. Start the Neo4j database: Make sure that the Neo4j database is installed and running.
  2. Importing data using Cypher: open the Neo4j browser and use the following Cypher query to import data.
LOAD CSV WITH HEADERS FROM 'file:///path/to/datafile.csv' AS line
MERGE (subject:Label {name: line.subject})
MERGE (object:Label {name: line.object})
MERGE (subject)-[:RELATION {name: line.relation}]->(object)

Replace “/path/to/datafile.csv” in the above code with the actual path of the data file. You can also modify the labels and relationship names as needed.

  1. Execute the import statement: Click on the run button in the Neo4j browser to import data into the Neo4j database.

In this way, you can batch import triple data into the Neo4j database.
