Hands-On Graph Analytics with Neo4j

By: Estelle Scifo

Overview of this book

Neo4j is a graph database that includes plugins to run complex graph algorithms. The book starts with an introduction to the basics of graph analytics, the Cypher query language, and graph architecture components, and helps you to understand why enterprises have started to adopt graph analytics within their organizations. You’ll find out how to implement Neo4j algorithms and techniques and explore various graph analytics methods to reveal complex relationships in your data. You’ll be able to implement graph analytics catering to different domains such as fraud detection, graph-based search, recommendation systems, social networking, and data management. You’ll also learn how to store data in graph databases and extract valuable insights from it. As you become well-versed with the techniques, you’ll discover graph machine learning in order to address simple to complex challenges using Neo4j. You will also understand how to use graph data in a machine learning model in order to make predictions based on your data. Finally, you’ll get to grips with structuring a web application for production using Neo4j. By the end of this book, you’ll not only be able to harness the power of graphs to handle a broad range of problem areas, but you’ll also have learned how to use Neo4j efficiently to identify complex relationships in your data.

Importing data from CSV or JSON

Even if you start your business with Neo4j as a core database, it is very likely you will have to import some static data into your graph. We will also need to perform that kind of operation within this book. In this section, we detail several ways of bulk-feeding Neo4j with different tools and different input data formats.

Data import from Cypher

Cypher itself contains utilities to import data in CSV format from a local or remote file.

File location

Whether importing CSV, JSON, or another file format, this file can be located in the following places:

  • Online and reachable through a public URL: 'http://example.com/data.csv'
  • On your local disk: 'files:///data.csv'

Local file: the import folder

In the latter case, with default Neo4j configuration, the file has to be in the /imports folder. Finding this folder is straightforward with Neo4j Desktop:

  1. Click on the Manage button on the graph you are interested in.
  2. Identify the Open folder...
