8.1.7 Computing Similar Vertices for a Vertex Batch

You can fetch the k most similar vertices for a list of input vertices as described in the following code:

• JShell
• Java
• Python

opg4j> var vertices = new ArrayList()
opg4j> vertices.add("Machine_learning")
opg4j> vertices.add("Albert_Einstein")
opg4j> batchedSimilars = model.computeSimilars(vertices, 10)
opg4j> batchedSimilars.print()

List vertices = Arrays.asList("Machine_learning","Albert_Einstein");
PgxFrame batchedSimilars = model.computeSimilars(vertices,10);
batchedSimilars.print();

vertices = ["Machine_learning","Albert_Einstein"]
batched_similars = model.compute_similars(vertices,10)
batched_similars.print()

The following describes the output result:
