Here is a video of an old version of my project. At the end when I apply the rule found in the "match subgraph" search (that I simply brute-force coded using "longest path matching first" and cypher, using django-neomodel library and classes), the ru...
I have a Neo4j Database with some graph created. I want to execute a set of cypher statements against this database from a java micro service. Two transactions are required to write data. If second transaction is failing, I want to revert the first t...
hi, i have a problem with this quary: match(n:Reato), (m:Reato) where n.Id > m.Id with toInteger(apoc.text.jaroWinklerDistance(n.totale, m.totale) * 100) as sim1,toInteger(apoc.text.distance(n.totale, m.totale) * 100) as sim2 where sim1 > 8...
I want to create a set of edges using LOAD CSV. I want their labels to be parameters from the file. I naively tried this: LOAD CSV WITH HEADERS FROM "file:///edges.csv" AS row MATCH(node1:row.tag1 {name:row.name1}),(node2:row.tag2 {name:row.name2}) C...
Hi, I have a graph containing neighbours, that is, structured in a star type schema in the language of DW modelling("Account" nodes having multiple "Fraud" nodes attached to them). I want to create a further relationship among Fruds nodes associated ...
I want to model a system as a graph. I'm starting small; I just want to model the power flow. So I created this graph: CREATE (n:World {name:"Power", provides:"power"}); CREATE (n:System {name:"Connector", carries:"power"}); CREATE (n:System {name:"...
I am looking at some recommender models and especially interested in the graph models like LightGCN. Except that Neo4j is natively stored as graph, I am wondering if GDS 1.7 can replicate similar G-DL models out there. Would be interested in an artic...
Good Morning Neos, Is there any chance to make the coding window in Neo4J-Desktop larger (let's say full screen)? I have to build a rather complicated query and the scrolling is a bit annoying.... Thank you, JJJ
Hi all, I don´t know where is the problem on the query, because the first part is too fast (a few ms) but the second has two when, which takes a long time to consult. (1min) The first part filters a lot of data, it doesn't seem like the amount of da...

I used to only create one database so I used the default database name 'neo4j-default'. Now I need to create one more database, and I want to explicitly give the db a name. How to do that? I thought I should change this line: my_driver = GraphDatabas...
Hi, I am not able to understand why the below query returns different results. MATCH (service:Service) WHERE coalesce(service.name = 'Service1Name', service.aliasValue = 'Service2Alias') RETURN service; Initially I have data as below CREATE (s:Servic...
Hi Everyone, I am facing a challenge calculating the sum of lower nodes in my graph. Consider the below scenario: Multiple such paths are present in the graph, and I want to calculate the sum of all the lowest nodes of Storage and store the value of...
