This Week in Neo4j: Graph Embeddings, OSS Vulnerabilities, Supply Chain Stack, Star Wars Graph, Chatbot MD, and More!

Feed: Neo4j Graph Data Platform. Author: Yolande Poirier. With graph data science, you can choose between several graph embedding algorithms, and generating low-dimensional vector spaces is easy. But how do you evaluate the embedding results in your machine learning application? Enter Emblaze, a Jupyter notebook widget for visually comparing embeddings developed by Carnegie Mellon University’s Data Interaction Group. In his tutorial, Nathan Smith shows you the power of the widget’s Python API to perform dimensionality reduction on multiple sets of embedding data and compare the embeddings using animated scatter plots.

10 Things You Can Do With Cypher That Are Hard With SQL

Feed: Neo4j Graph Data Platform. Author: Enzo. Editor’s note: This presentation was given by Michael Hunger in December 2021 at Neo4j Connections: Graphs for Cloud Developers. SQL has been around for a long time; it’s a powerful query language, but there are some things that just make more sense in Cypher. I’ll occasionally show SQL as a point of comparison, but in general, I will focus on the Cypher aspects because that is what we run here at Neo4j. Before I jump into my list of ten things that you can do better in Cypher, I will first provide a ... Read More

Clone an Instance in Aura to Optimize Your Development Cycles

Feed: Neo4j Graph Data Platform. Author: Angela Zimmerman. “Give me more manual toil and database management tasks in my daily development workflows,” said no developer ever. One of the key goals of every developer is to optimize development cycles on a daily basis so you can spend more time coding and adding value for your users, and less time managing environments. Team Aura has delivered a number of features to the platform that allows you to achieve that outcome. One of those is the ability to clone the data from your AuraDB instances to new and existing instances. I’ll briefly ... Read More
Cryptocurrency analysis: visualizing the WannaCry attack
Feed: Cambridge Intelligence. Author: Matt Latham. Remember the WannaCry ransomware attack? Launched in May 2017, it was one of the most devastating and extensive cyber attacks in history, affecting over 200,000 computers across 150 countries. And as the criminals behind the attack demanded payment in bitcoin, it also turned the spotlight on cryptocurrency analysis. In this post, we explore the role data visualization tools play in detangling the cryptocurrency transactions involved in ransomware attacks like WannaCry. We dig deeper into the bitcoin ransoms paid by some victims and investigate how attackers managed to exchange their cryptocurrency for cash. Timeline and ... Read More
This Week in Neo4j: Space Junk, SHACL, Neo4j Apps with Python, Under The Hood, Spring Data, and More
Feed: Neo4j Graph Data Platform. Author: Yolande Poirier. You’ve probably heard about space debris and the growing risk of collision to satellites and space stations. According to Moriba Jah, who created ASTRIAGraph at the University of Texas at Austin, there are 26,000 trackable objects in space (excluding the smallest), of which only around 4,000 are currently working. Moriba collects information on orbiting objects by aggregating information from different countries, companies, other scientific researchers, amateur telescope astronomers, and more. The resulting graph identifies individual objects and their distances from each other. Enjoy this fascinating read on tracking space garbage! ... Read More
Achieve Unrivaled Speed and Scalability With Neo4j

Feed: Neo4j Graph Data Platform. Author: Angela Zimmerman. As data volumes continue to grow, applications need to scale up and scale out to handle the increased load. Both approaches have their advantages and disadvantages, and the best approach varies on the specific requirements of the application. However, data integrity and performance must be maintained across all architectures – whether on-premises, hybrid, or cloud-based. With the right approach, data can be managed effectively at scale, providing the foundation for performant applications. There are challenges that every organization must overcome to attain seamless performance and scale for their applications.

Graphs for Cybersecurity: Introduction

Feed: Neo4j Graph Data Platform. Author: Enzo. Cyberattacks had been on the rise for years, with nation state threat actors and foreign hacking collectives joining in, devoting more time and resources to attacks. At the same time, the shortfall in talented staff available to fight these threats also increased. Then the COVID-19 pandemic struck, forcing many businesses to shut down their physical buildings, creating an unprecedented demand and pressure on digital platforms as businesses shifted to securing work from home at scale. Cyberattacks skyrocketed in 2020. The FBI saw a never before seen 300% increase in cybercrime reports in 2020 ... Read More
This Week in Neo4j: New Neo4j + Java Course, Interactive Dashboards, Intelligent Supply Chain Apps, and More Copy

Feed: Neo4j Graph Data Platform. Author: Yolande Poirier. A new course is available on GraphAcademy for Building Neo4j Applications with Java! Michael Hunger and I collaborated to create a hands-on course that starts with a project skeleton and guides users through writing code to build a completed IMDB-clone application with Neo4j and Java. In the app, we can store and query users, movies, genres, people, and user favorites.
The data that feeds the fully-fledged application includes the MovieLens recommendation dataset, augmented with themoviedb.org movie and cast data. Data results are presented to the user through a beautiful webpage supported ... Read More
