Hi, I have the following problem. I developed a code on Spark/Python for k-medoids. Now I've managed to load the medoids that come from python directly into neo4j, meaning that spark communicates with neo4j. I also uploaded the data from a csv to neo...
Hello friends! So... about a half year ago we switched the platform used here on community.neo4j.com from Discourse to a vendor called Khoros. We were hopeful about Khoros as a platform that we could build upon to make a great website for the communi...
Hi Neo4j community, Following on from some previous advice (thank you @Rcolinp ) I was able to import the following ontology file (Thesaurus_22.06d.OWL (https://evs.nci.nih.gov/ftp1/NCI_Thesaurus/Thesaurus_22.06d.OWL.zip)) into a neo4j knowledge gra...
Hello everyone I need to write a cypher query for a below scenario. Given a list of strings, count the number nodes in graph where levenshtein similarity between node name property and strings from the list is more than certain thershold. I was able ...
Hi everyone! I'm trying to query the following pattern: (a)-[r1]->(b)-[r1|r2*]->(c)-[r1]->(d) and a, b, c, d might belong to different categories, and they all have the same label. The Cypher query I'm running is (cat means category): MATCH p=(a)-...
Hi, excited to join and hoping you guys can help make my first step. I would like to find out if it were possible with NEO4J to persist REST API response data in database? So I want to import data into my database (from REST API) to then query that. ...

Hi,So I'm following the instructions for "Importing CSV files with the Neo4j Data Importer" of the course "Importing CSV Data into Neo4j". Although the import is successful and I get the number of nodes and relations correctly, I get an error when cl...
Hi! I've been trying to import an ontology into my database. I've tried a few different file types (.ttl, .xml, .rdf), but I'm getting error messages each time. Most recently, the query: CALLn10s.onto.import.fetch("https://github.com/foodkg/foodkg....
Trying to get going with the new neo4j extension, and I'm having some trouble troubleshooting my troubles! I added a connection to a remote db that I work on, but I get prompted with if I try to run a .cypher file. On the other hand it does seem to...
I am in the section using the Neo4j Data Importer (https://graphacademy.neo4j.com/courses/importing-data/2-using-data-importer/2-c-importing-CSV/)and looks like the check database function is not working correctly. Even on an empty database its throw...
Hello, I am new to neo4j and have went through the documentation for applying a node classification on some data of mine, much like in the following tutorial . In my case, there will be an ongoing stream of new samples which will be represented as ne...

I'm trying to get the top x unique shortest node paths. If I use a simple projection: CALL gds.graph.project("graphSingleType", "*", {TYPE: {type: "*"}}) Yen's will return the same node path multiple times having taken different parallel edges betwee...
Hello! I have this relatively simple query, and it takes about 1+ second to run. I was wondering if I can make it a bit faster but I don't know where to optimize exactly. Any ideas? match (u:User {app_id: $app_id, external_id: $id})-[:PURCHASED|:ADDE...
