This Week in Neo4j: HealthECCO, Graph Algorithms in Rust, Nobel Prize, AWS Lambda, Python, IntelliJ, and More

Welcome to this year’s first newsletter! Here are some of this week’s highlights: In “Create Dynamic Serverless Applications with Neo4j Graph Database and AWS Lambda,” you’ll learn to populate front-end applications with connected data.

In the article “Extracting insights from HealthECCO Knowledge Graph,” you can read how data scientist Artem Ryasik uses Neo4j native Graph Data Science library to create an in-memory graph projection of data from Covidgraph, a biomedical graph by HealthECCO, and applies multiple algorithms for analysis and machine learning. In other articles of interest, learn to debug a Spring Data Neo4j app connection or create a knowledge graph of recent Nobel Prizes in Physics, Chemistry, Medicine, and Literature.

Since learning new things is on everyone’s list of New Year’s resolutions, try checking the NODES session recordings for fresh ideas on a great many topics.

P.S.: If you’re a developer building modern applications with GraphQL, don’t forget to take this short, two-minute survey. We want to hear from you!

Corey Lanum has worked with the largest defense, intelligence, security, and anti-fraud organizations in North America. He has a diverse background working on big data initiatives and implementing proven solutions that provide customers with key insights into their data. He is the author of the book “Visualizing Graph Data” from Manning Publications. You can follow him on LinkedIn.

In his NODES 2022 presentation, he demonstrates how to present graph analytics in a way that users can understand easily. Watch it now!

KNOWLEDGE GRAPH: Extracting insights with HealthECCO
In this blog, Artem Ryasik represents biomedical data as a graph to uncover meaningful relationships between genes and diseases. He applies different clustering algorithms to a subgraph to see if the clusters are stable, interprets their content, identifies which nodes are the most significant, and describes how these results can be used in practice.
In the latest episode of Discover AuraDB with Michael and Alexander, a dataset of the most recent Nobel prizes is imported and queried as a graph. Michael Hunger explains how they use this dataset to create a knowledge graph connected to papers, authors, publications, and research data.
NODES SESSION: Native Graph Algorithms in Rust

Martin Junghanns and Paul Horn present a Rust library called graph that includes an in-memory graph representation, APIs for building in-memory graphs from various data sources, and a small collection of high-performance graph algorithms. The library also contains an experimental Python API, which allows users to integrate graph in their Python applications and benefit from native performance.

CLOUD APP: Create Dynamic Serverless Applications With Neo4j Graph Database and AWS Lambda

In this article, Antony Prasad Thevaraj from AWS, and Jennifer Reif and Michael Hunger from Neo4j, explain how to use the AWS Cloud Development Kit to build an AWS Lambda function in Java that connects to Neo4j. The AWS CDK framework can be used to build dynamic serverless applications where the front-end scales based on system demand.

GRAPH DATABASE: Using Neo4j to Find the Most Powerful Package

In this post, Tom Nijhof, Back End Developer at CytoSMART, graphs a database of over 5000 Python packages to list the direct and indirect dependencies of each package. In doing so, he exposes vulnerabilities that presage further Left-pad type disasters.

TUTORIAL: Non-Suspending Breakpoints With IntelliJ

Michael Simmons explains how to debug an issue in Spring Data Neo4j with a breakpoint technique that allows, for example, flat map operator parallelism and lets you debug the connection.
