The  .vectors.get  algorithm

The .vectors.get algorithm retrieves the embedding for a node.

.vectors.get  syntax

MATCH( n {`~id`: "the ID of the node"} )
CALL neptune.algo.vectors.get(n)
YIELD embedding
RETURN n, embedding

.vectors.get  input

• a source node or nodes   (required)   –   type: Node[] or NodeId[];   default: none.

  The result of a MATCH statement that produces the node(s) for which you want to retrieve the embedding.

Warning

Be careful to limit MATCH(n) so that it doesn't return a large number of nodes. Keep in mind that every source node in the n result invokes .vectors.get once. Too many inputs can therefore result in very long runtimes. Use LIMIT or put conditions on the MATCH clause to restrict its output appropriately.

.vectors.get  outputs

For each source node provided:

• node   –   The source node.

• embedding   –   The embedding of that source node.

.vectors.get  query example

MATCH ( n {`~id`: "0"} )
CALL neptune.algo.vectors.get(n)
YIELD embedding
RETURN n, embedding

Sample  .vectors.get  output

Here is an example of the output returned by .vectors.get when run against the sample Wikipedia dataset using the following query:

aws neptune-graph execute-query \
  --graph-identifier ${graphIdentifier} \
  --query-string "MATCH ( n {`~id`: '0'} )
                       CALL neptune.algo.vectors.get(n)
                       YIELD embedding
                       RETURN n, embedding" \
  --language open_cypher \

In some parts of the world\\, it is called railway time. Also\\, the international standard notation of time (ISO 8601) is based on this format."
