Neo4j unwind exampleFor example, I plan on keeping id so we can use it as a unique index for each paper. After that, I want to get an individualized list of each author. Also, the authors_parsed column gives us a much cleaner listing of all authors. Definitely we will keep the title column as the main property for the paper.Example. This is the Cypher, Neo4j's query language. In many ways, Cypher is similar to SQL if you are familiar with it, except SQL refers to items stored in a table while Cypher refers to items stored in a graph. First, we should start out by learning how to create a graph and add relationships, since that is essentially what Neo4j is all about.by Andrea Santurbano.

The following features are supported: Marshalling from Neo4j Nodes to Groovy types and back again.Neo4j isn't without its share of idiosyncrasies. Nodes have labels. The way I was originally modeling the data, a label was a conceptual group - for example, Film or Manga. Labels are not the same as a table, since a node can have multiple labels. Neo4j nodes have properties, which don't need to be present in all nodes.Recently personalized pageRank was added to Neo4j graph algorithms library and I was looking for a cool example to demonstrate its applications.
