This appears to be converging after a single iteration -- which suggests LPA isn't actually doing anything.
There are a couple of issues that stand out:
You're using seedLabel in the nodeQuery, but you're passing seedProperty: 'seed_label', so there's effectively no seed label being used. And,
Your node queries subsets your graph to only articles that have n.familyComponent=0 so I suspect you're generating a very disconnected subgraph (you can check by running WCC on the same cypher projection).
Try looking into those, and I suspect you'll get it sorted out pretty quickly
Thank you for your answer. I tried to correct it but the problem remains. The LPA is doing nothing. Even without seed labels the LPA doesn't work.
My data looks like this:
I have 530 articles and 842 keywords.
The article nodes have id property and title content property.
The keyword nodes have id property and keyword property.
The relationship APPEARS_IN has weights property. Weights are the number of time that the keyword appears in an article.
The data in Neo4j looks like this: I have a big network at the center and the other articles are not connected to others. That's why I ran wcc before applying LPA. I wanted to only keep the big network with the wcc (at the center of the image) and next apply LPA. I don't know if it is the good method.
Maybe my request is not okay, I tried to project a bipartite graph to a monopartite graph (I also tried firstly a similarity algorithm before applying LPA) because I have the following relationships:
