Re: [Neo4j] Question about labelling all connected components

The union find algorithm would be appropriate for labeling connected components as you build the graph. Andrew Baine On Thursday, July 22, 2010, Arijit Mukherjee ariji...@gmail.com wrote: Thanx to both of you. Yes, I can just check whether the label exists on the node or not. In my case

Re: [Neo4j] Performance problem inserting nodes with many short string properties

Great. Since you summarize the problem on that page and only mention small transactions, I'd think you might want to mention my problem too... that making a transaction *too large* also demolishes performance, because the transaction's on the heap. - Jeff Klann On Thu, Jul 22, 2010 at 5:19 PM,

[Neo4j] Subgraphs

All, We are considering leveraging the concept of subgraphs as an approach for interactively visualizing large quantities of data. The idea is that by aggregating collections of nodes that share some characteristic into a single node, we may be able to reduce a graph's complexity to the point

Re: [Neo4j] Subgraphs

Hi Paul My questions for the group are: 1) Are there any suggestions for how subgraphs might be algorithmically determined? Are there clustering algorithms that might be leveraged? What you describe brings to my mind the field of community detection techniques, i.e. methods that

Re: [Neo4j] how to self define node?

Ids (type long) are generated internally and cannot be supplied from outside. However, you can use another arbitrary property key to represent such a user-defined ID... For easy lookup also index that property for each created node and query the index to get the node for a specific ID. 2010/7/22

Re: [Neo4j] TimelineIndex usage

2010/7/23 Tim Jones bogol...@ymail.com Hi, I need to be able to retrieve nodes whose timestamps are greater than a particular time. I've been trying to use a TimelineIndex, but didn't realise that it was a persistent structure - I've written code that will create a new Timeline each time

Re: [Neo4j] TimelineIndex usage

I'm not worried that nodes will become related, I just wanted to make sure that because they aren't already related that this wasn't going to cause a problem before I implement the Timeline - I've already spent longer than I'd intended on this and don't want to reimplement it if it's not
