Custom Page Rank

================

This is an unmanaged extension running a Custom Pagerank algorithm on Companies with a SIMILAR relationship score >= 0.80.

# Quick Start

1. Build it:

        mvn clean package

2. Copy target/pagerank-1.0.jar to the plugins/ directory of your Neo4j 2.3.0-M03 server.

        mv target/pagerank-1.0.jar neo4j/plugins/.

3. Configure Neo4j by adding a line to conf/neo4j-server.properties:

        org.neo4j.server.thirdparty_jaxrs_classes=com.maxdemarzi.pagerank=/v1

        

If you need to configure 2 extensions at the same time, use a comma between them:

        

        org.neo4j.server.thirdparty_jaxrs_classes=com.maxdemarzi.recruit=/v1,com.maxdemarzi.pagerank=/analytics

4. Start Neo4j server.

5. Create sample dataset:

        CREATE (a:Company {name:'a'})

        CREATE (b:Company {name:'b'})

        CREATE (c:Company {name:'c'})

        CREATE (d:Company {name:'d'})

        CREATE (e:Company {name:'e'})

        CREATE (f:Company {name:'f'})

        CREATE (g:Company {name:'g'})

        CREATE (h:Company {name:'h'})

        CREATE (i:Company {name:'i'})

        CREATE (j:Company {name:'j'})

        CREATE (k:Company {name:'k'})

        CREATE

          (b)-[:SIMILAR]->(c),

          (c)-[:SIMILAR]->(b),

          (d)-[:SIMILAR]->(a),

          (e)-[:SIMILAR]->(b),

          (e)-[:SIMILAR]->(d),

          (e)-[:SIMILAR]->(f),

          (f)-[:SIMILAR]->(b),

          (f)-[:SIMILAR]->(e),

          (g)-[:SIMILAR]->(b),

          (g)-[:SIMILAR]->(e),

          (h)-[:SIMILAR]->(b),

          (h)-[:SIMILAR]->(e),

          (i)-[:SIMILAR]->(b),

          (i)-[:SIMILAR]->(e),

          (j)-[:SIMILAR]->(e),

          (k)-[:SIMILAR]->(e);

6. Call the pagerank endpoint:

        :GET /v1/service/pagerank

        

You should see "PageRank for Company using SIMILAR relationship type Completed!"

7. Check the pageranks of some nodes:

        MATCH (n:Company) RETURN n.name, n.pagerank LIMIT 25;
