Hi guys, I'm running the 11 snapshot now. The phrase You just have to add
'Neo4jService' to the list of configured services is too cryptic for me.
Just too many places where I can configure stuff, including services on my
Mac. Any explication would be welcome.
Thanks

Hi,
I see this question is a bit out of date.
Has there been a change in Neo4j that might allow what you called the
common meaning of replication factor?
Thanks,
Alex.

as part of my master thesis I developed a new SPARQL plugin for Neo4j.
The current plugin https://github.com/neo4j-contrib/sparql-plugin is

Did you try to run it with -Dfile.encoding=UTF-8 ?
And perhaps an importer in Java/Groovy is more stable for reading the data?

If you have a library for http requests (libcurl?) and json parsing it is
pretty simple to get started.

Right now there are afaik only a few attempts with c / c++
One of which is neo4c https://github.com/wfreeman/neo4c

Hi Eric,
did you do:
create index on :Document(source_id);
Also your relationships are they bi-directional between the same two nodes?

Afaik there are no plans for providing expected results (esp, as those can
grow gigantic).

Hmm Neo4j graph search uses the Neo4j property graph metadata to do its
work and rendering to cypher for the execution.
Both of which I don't hink you get (easily) in Hadoop/Impala.
What do you actually want to do, perahps you can describe your use-case a
bit.
Cheers, Michael

I don't want to sound like I'm pimping another graph database, but it
sounds like you might be talking about Giraph, which is a graph database on
top of Hadoop.

Niclas,
this is amazing, thanks so much for creating it and also making it
available for the open source community.
Do you have any information about the model you use to store RDF
efficiently and any performance numbers? Esp. comparing it with cypher?
That would be really interesting.
Do you
As far as I know this is not exposed.
The closest that is there is to pass in a lucene query object into neo4j
when querying data (e.g. like sort or topk-documents)
You can have a look at the LuceneIndexImplementation.java class
For text categorization, Kenny wrote a Neo4j extension called
