Hello, I want to write a user-defined function that would take a list of lists as an input, with each 'inner' list containing 2 integers - start date and end date, for example: Input: [[1,3],[2,6],[8,10],[15,18]] and would return the list of lists wi...
Our graph is a tree. I'm trying to build a query that given a node returns that node and optionally its ancestors and optionally its descendants. In other words I want to parameterize the query with parameters includeAncestors and includeDescendants....
I am running eigenvector centrality in stream mode and all null values are returned. What causes eigenvector centrality to return null score values.
Hi, don't know if here or on Github is the place for this, however we've come across an issue while using the official neo4j docker that I'm not entirely certain how to place. Here's the setup: Neo4j Version: We run neo4j:latest containerLanguage: Py...
Hi everyone! I've made some calculations on my network (eigenvector, degree, etc.) and for some nodes i got the result 0 and null (and by null i mean i got nothing - blank record). What is the difference between those two outcomes?
Hello, I'm trying to use rwr on a large scale graph database (Neo4j 4.4.5) and when I use the gds (2.0.3) in my Neo4j Desktop (1.4.15), as per https://neo4j.com/docs/graph-data-science/current/management-ops/projections/rwr/ I get the following mess...
Hi, I am using Neo4j to import and export RDF data, where I use the following prefix for "schema.org". @prefix schema: <http://schema.org/> . I am importing my RDF data using "SHORTEN" for "handleVocabUris", so I follow this guide to define custom pr...
In networkx community API — Community detection for NetworkX 2 documentation the resolution parameter allows specifying the size of the communities. This parameter does not seem to be available in GDS. Am I overlooking it? If not, where/how is it cal...
Hi all, I am experimenting with Neo4j and SHACL for validation purposes. I was able to load some RDF data (I used the "SHORTEN" value for handleVocabUris), load a schema (which defined the classes and shapes) and then ran the validation. This works. ...
The name of each node is very long, therefore, I cannot see all the texts while using Bloom. I enlarged the circle sizes, but the font sizes enlarged hand in hand. Is there any method to show all the texts of a nodes, or just enlarge the node size...
Hi all, I have a list of Products and Persons. A Product can have relationships to different Persons, such as "hasProductOwner", "hasDeveloper", "hasTechnicalWriter", etc. (these are effectively roles that a person can have for a Product). A Person c...
Hi I just can't get the following. I'm using Google co-lab. The commented out line works as expected but after trying various options from threads I still can't get it. I'm just trying to pass the entity_type variable in after declaring it. Also onc...
I have text data that I would like to allow both upper and lower case letters. But want to ignore case when doing merge operations. For example, how do I apply toLower to o.name before it is compared to $name? MERGE (u)-[:ACCESS]-(o:Object {name: toL...
MATCH (m:Sports)-[r:hasPlayer]-(n:Sports) RETURN properties(n) as properties1, properties(m) as properties2 limit 100000 This takes quite a while to complete given around 50000 Sports node. I hope it can be finished under one 1 second, since it's...
