I have a graph database of personnel, and a separate CSV file containing a list of VIPs. The reason why the list of VIPs is in a standalone CSV file is because this list changes frequently, and will be updated by users not trained in Cypher. I have t...

How do I do multiple aggregations in Neo4j without repeating my MATCH query? Let's say I have a database consisting of customers, the restaurants they go to, and the record of the bills for each customer/restaurant for a particular year. Note that a ...

I'm trying to run the Louvain method of community detection on my database to group some of my nodes into clusters. However, I kept getting different results even just by trying to sort my results. This is the result I get when I run the Louvain algo...

Hi there! Thanks a lot for your help! Perhaps I should have been clearer. My problem was that the communities itself does change when I ran it in a different manner. From domain knowledge, I know that the 4 particular nodes that I'm looking at are ac...

Another possible solution without using the APOC plug-in MATCH (s:Student)-[:READ]->(b:Book) WITH s, COUNT(b) AS no_of_books ORDER BY no_of_books DESC WITH COLLECT ({Student_Name: s.Name, No_of_Books: no_of_books}) AS books_per_stu WITH books_per_stu...
