韓流 TRACKER

Based on neo4j:4.2.0

Quickstart

1. Build the image and start the neo4j container

   export TAG=`date +"%Y%m%d%H%M"`
   export PW= #insert password here
   export NEO4J_AUTH=neo4j/$PW
   docker build --no-cache --build-arg NEO4J_AUTH -t hanryu/tracker:$TAG .
   rm -R $(pwd)/data/{databases,dbms,transactions}
   docker run -p7474:7474 -p7687:7687 -v $(pwd)/import:/import -v $(pwd)/data:/data \
   -e NEO4J_AUTH=$NEO4J_AUTH --user=$(id -u):$(id -g) hanryu/tracker:$TAG &
   unset NEO4J_AUTH

   Run ctrl + C or docker stop $(docker ps | grep hanryu | cut -d" " -f1) to stop the container.

   If you've previously created the database i.e. in $(pwd)/data, remember to remove the subdirectories when changing passwords. The database will otherwise expect the password you used the first time you set it up.

Step-by-step

1. Start the neo4j container

   export PW= #insert password here
   docker run -p7474:7474 -p7687:7687 -v $(pwd)/data:/import -e NEO4J_AUTH=neo4j/$PW neo4j

   See How-To: Run Neo4j in Docker

2. Go to http://localhost:7474/browser/ on your favourite browser

3. Load data and display (see cypher script)

   LOAD CSV WITH HEADERS FROM 'file:///Cast.csv' AS row
   UNWIND split(row.Role, ' / ') AS name
   MERGE (role:Role {title: row.Title
   ,                 role:  name
   ,                 actor: row.Actor
   })
   WITH role, row
   MATCH (title:Title {title: row.Title})
   MATCH (actor:Actor {actor: row.Actor})
   // Create relationships between actors, roles and titles
   MERGE (actor)-[:AS]->(role)
   MERGE (role)-[:IN]->(title)
     ON CREATE SET role.Role = row.Role;
   
   // Display
   MATCH p = ()-[]-()-[]-()
   RETURN p
     LIMIT 750
   
   // up to 6 deg of separation
   match p=(:Actor {Actor: 'Park Hyung-sik'})-[*1..6]-(:Title) return p
