Experimenting with the benchmark

To try out new queries, it is recommended to use an interactive UI, such as Neo4j's web browser.

Experimenting using the Neo4j database

Download, unzip Neo4j, start and visit http://localhost:7474/.

To load models conveniently, use the APOC library. Get the latest JAR from the APOC releases and copy it to the neo4j/plugins directory.

Edit the neo4j/conf/neo4j.conf file and add the following lines:

apoc.import.file.enabled=true
apoc.export.file.enabled=true

dbms.security.procedures.white_list=apoc.coll.*,apoc.load.*

Use the apoc.import.graphml procedure to load it. For example, to load a small well-formed model (railway-batch-1.graphml), use this command:

CALL apoc.import.graphml('/absolute/path/for/file/railway-batch-1.graphml', {batchSize: 1000, storeNodeIds:true, readLabels:true, useTypes:true})
YIELD nodes, relationships
RETURN *

To get a sample of the model, simply issue:

MATCH (n)
RETURN n
LIMIT 25

It's possible to provide parameters on the Neo4j browser's web UI. To see how, type :help param.
