Overview of this book

Neo4j, along with its Graph Data Science (GDS) library, is a complete solution to store, query, and analyze graph data. As graph databases are getting more popular among developers, data scientists are likely to face such databases in their career, making it an indispensable skill to work with graph algorithms for extracting context information and improving the overall model prediction performance. Data scientists working with Python will be able to put their knowledge to work with this practical guide to Neo4j and the GDS library that offers step-by-step explanations of essential concepts and practical instructions for implementing data science techniques on graph data using the latest Neo4j version 5 and its associated libraries. You’ll start by querying Neo4j with Cypher and learn how to characterize graph datasets. As you get the hang of running graph algorithms on graph data stored into Neo4j, you’ll understand the new and advanced capabilities of the GDS library that enable you to make predictions and write data science pipelines. Using the newly released GDSL Python driver, you’ll be able to integrate graph algorithms into your ML pipeline. By the end of this book, you’ll be able to take advantage of the relationships in your dataset to improve your current model and make other types of elaborate predictions.

Part 3 – Making Predictions on a Graph

After building a graph and learning how to characterize and visualize it, it’s time to learn about techniques to make predictions from graph data. You will start by using a well-known Python library, namely scikit-learn, and extract data from Neo4j to build a model. Then, you will learn about node embedding algorithms that are built to automatically create node features based on the graph structure. You will then use these embeddings to build node classification and link prediction pipelines, without the need for a third-party library since everything will be managed by the Graph Data Science (GDS) library.

Finally, in the last chapter, you will build a GDS extension and write your own graph algorithm that behaves in the same way as all built-in GDS procedures.

This part includes the following chapters:

  • Chapter 6, Building a Machine Learning Model with Graph Features
  • Chapter 7, Automatically Extracting Features...
