I have two CSV files.
1. all_entities.csv: The list of all node entities and their attributes, e.g., name, type
2. relations.csv: Three columns that have EntityA, relation, EntityB
I created nodes using
LOAD CSV WITH HEADERS from "file:///all_...
Hi folks,
I am attempting to get a subgraph and graph data(as '.txt 'or other formats) from a big graph
Approach 1:
Randomly sample all nodes types from the large graph
MATCH (source: Node)-[r*..]-(target: Node)
WHERE source.name<>target.nam...
Hi, great minds! I am new to neo4j and currently exploring an existing graph to extract data for downstream tasks.I would like to get all pairs of nodes and their relationship from the graph. MATCH (n)-[r]-(n1) WHERE n<>n1 AND n1>n RETURN * This wil...
Hi Ramoscava,
I have a similar issue, and all effort to get the triples into rdf or csv or txt file was abortive. Could you give a code snippet or point me in the direction of a sample?
I deeply appreciate your help, maybe a few more lines here could clarify my issues:
Say I have allsimplepaths(A, B, '', 3) that look like this:
[A –>relation1 –>B][A –>relation2 –>B][A –>relation2->C->relation 1–>B][A –>relation5->D->relation 3–>B][A...
Actually, the match is between 2 node types, not the whole db. MATCH p = (n:Node{type: 'typeA')-[*1..2]-(n1: Node(type: 'typeB') This is so helpful! I haven't explored SKIP and LIMIT use before RETURN. Thanks a bunch for that.
I noticed that the query gives only the first-order connection between 2 nodes; however, I will need at least the second-order relationship for my downstream application. I have tried:MATCH (n)-[r*1..2]-(n1)
WHERE n<>n1 AND id(n)<id(n1)
WITH n.name...
