I am trying to run the weighted Jaccard algorithm on my graph (following the Neo4j documentation as reference) The code: CALL gds.nodeSimilarity.stream('test', { relationshipWeightProperty: 'strength', similarityCutoff: 0.1 }) YIELD node1, node2, sim...
Hi, I am using the collapsePath functionality to create specialised subgraphs. There is a case when many paths map to a single mutateRelationshipType. For example I would like to do something like: CALL gds.alpha.collapsePath.mutate( 'jscgocw...
I need to implement a custom propagation algorithm that starts from a given node and visits its neighbors and update their properties accordingly based on the previous node properties. Example use case is, a quality flag that changed in a given node ...
I am a newbie. I am a faculty and NWU and we have a StreamingAnalytics course where we walk students through a couple lessons on Neo4J. We have a retail example that we use to walk students through links, relationships. One of the exercises uses gds....
Hi, Is there any method for inspecting the output of GDS projections (within the community edition where querying projection graphs isn't possible)? So I am attempting to use gds.graph.list(). The underlying metadata regarding the graph seems very in...
So I have a graph of nodes -- "Papers" and relationships -- "Citations". Nodes have properties: "x", a list with 0/1 entries corresponding to whether a word is present in the paper or not, and "y" an integer label (one of the classes from 0-6). I wan...
Hello! I just started my journey with neo4j. In one of my tasks I was supposed to run the eigenvector centrality algorithm however that process failed. There seems to be a problem with the size of the number, i.e. the amount of decimals (screenshot o...
Hi @mark.needham, I'm having problems getting NEuler to work. Neuler hang on "selecting database" step with "Refreshing" stage Please can you help?
Hello! I am wondering if there is a way to export algorithm's scores to csv from the cypher shell. I know there is a way to do it via neo4j Desktop but I am working with huge data and I need to run the algorithm on the cypher shell since it is faster...
I am running the random walk algorithm on my graph with just 4 nodes and 8 edges as a test. When I don't specify the sourceNodes parameter, everything is fine and I get walks from all the nodes. Here is my code: CALL gds.beta.randomWalk.stream( 'exam...
Hi, I have the following graph visualization and I don't understand why the scores are not the same. Let's assume that all 3 nodes (A, B, C) have an outgoing HAS relationship with american and casual ONLY. It makes sense to me that nodes A and B woul...
Hello, I am trying to calculate some metrics (pagerank.....) In a very big graph database that can not be projected in memory. So i think using Neo4j GDS - Graph Data Science is out of question? Can i use GDS without saving all db in memory? Is ther...
How do I get all possible combination of pairs nodeSimilarity? In my graph I have 4893 persons and I am computing nodeSimilarity using a weighted graph. All possible, distinct pairs, from my list should yield about 11968278 pairs of nodes + a score f...
Hello, I would like to check if a graph projection exists and if yes, drop it. Here is the code tried without success: </>CALL gds.graph.list() YIELD graphName WITH graphName AS graph CALL gds.graph.drop(graph) YIELD graphName RETURN graphName</> Neo...
MacOS 10.15.5 neo4J Desktop v 1.4.5 I created a neo4j database (v 4.2.4) to test graph embeddings. Using the PlugIns tab I loaded APOC 4.2.0.4 loaded fine. However, GDS Library did not load as i received this message. No compatible version found. Th...
