Ah this discussion is interesting, I want to join and throw in sonme idea too.
If a user can visit a place for multiple times. And if there are 100 user visit
USA. So we should suggest top 10 only.
Would traversing the graph be more efficient than normal database query?

Hi,
This week I implemented basic insert and delete capability for Neo4j
Spatial type functions,
added ST_GeomFromText as a new spatial function and at the moment I
prepare everything to be able to commit it
to the main repository of Neo4j Spatial, this means testing,
documentation, etc...
Have you got any use case where this would be a necessary thing to have and
where the current model wouldn't suffice? Just curious.

I agree,a Node is something that has 2 (user managed) fields:
Relationship[]
Property[]
and a
Yes a more robust solution would be to cast to a Number:
return ((Number)relationship.getProperty( costpropertyName
)).doubleValue();
I'm assuming that's what you meant in the first place, no?

Hi Aman,
This is the classic friends-of-friends problem recast as friends-of-places. The
hard thing about places (as opposed to most normal friends) is that they tend
to be popular. While I might only reach hundreds of friends-of-friends (if I'm
lucky!), being recommended people that have
That's a great point.
In Neo4j you can add properties to your relationships so that:
Jim --VISITED (numberOfTimes: 20) -- Melbourne
Then you can use the numberOfTimes property to determine whether or not you'd
like to include the person/city in the recommendations you're making. In this
case

I am working on neo4j for past 2 months and found it everything which
I needed. But the problem coming is integrating it with php.I was looking
into php-java bridge and it looks a headache. Python binding of neo4j are
old and there is not much on net to work with it. My teammates dont
Hi Manav,
You may want to consider Groovy (http://groovy.codehaus.org/). Why?
1. It is an easy to learn scripting language with constructs nearly
analogous to Ruby.
2. It is a superset of Java so you can do Java programming if you wish.
3. You can use it as a REPL or
I am using only one relationship type in my index tree, and made traversal
decisions based on properties of the tree nodes, but have considered an
'optimization' based on embedding the index keys into the relationship
types, which I think is what you did. However, I am not convinced it will
work
Hi Manav,
Although the REST API isn't as flexible as the native JVM API, it's still
suitable for large projects. You just have to be even more careful about your
design.
This means it is suitable for PHP, and I've seen the a lot of PHP activity on
the neo4j twitter stream in the last few
I think I asked this before, but can the Neo team provide builds with the
appropriate source included in the distribution? Two main reasons:
1) Don't want/need to have Git stuff installed
2) Want to make sure the source associated with a specific Neo build is
the exact source used
Hi Rick,
I can see a bunch of source jars in the Neo maven repository:

Does that help?

Hi, Jim.
It would, if they were for the released and milestone builds. ;-)
I think those are snapshots from the automatic nightly builds.

Gah!
That Maven stuff gets everywhere. It's like treading in dog poop. Actually no,
it's worse than that.
OK, I'll add to our build backlog that we will emit binary and source + binary
editions per numbered build (the sensible way of publishing every green build

The cost per interaction is the network cost + transaction cost. You can make

Thanks for the valuable input... The use case I mentioned here (using
only visited places) was a simplistic version of the real one,
because, just as you said, I'd be getting large number of results in
that case... I'd check out pattern matching and Cypher to ease me in
my project... Neo4j
Jim,
I was going through Cypher and a question came into my mind regarding
pattern matching... How is pattern matching done in neo4j? I mean, how
are nodes and relationships matched in case of large data-sets?

You can get the sources from github as zip/tarballs. Just use:
