Welcome to this week in Neo4j where we round up what’s been happening in the world of graph databases in the last 7 days.
Featured Community Member: Samuel Yang
This week’s featured community member is Samuel Yang, a.k.a @cyphersam, Senior Software Engineer at Comcast.
Samuel Yang – This Week’s Featured Community Member
Sam has answered more than 1,000 questions, showing people how to solve problems with the Cypher query language, optimise queries, and configure their Neo4j servers.
On behalf of newcomers to graphs and Neo4j everywhere, thanks Sam for all your efforts!
Release all the things
There were release galore this week so there’s lots of new stuff to get your hands on.
Neo4j itself released versions 3.0.11, 3.1.6, 3.2.3, and 3.3.0-alpha05. There is now IPv6 support for clusters and improved support for really large imports in versions 3.1, 3.2, and 3.3. Check the release notes of the individual versions for more details.
This week also saw the first public release of the Neo4j graph algorithms library. The library contains all your favourite graph algorithms for page rank, betweenness centrality, minimum weight spanning trees, and more. Give it a try and let us know how you get on.
A Graph of Thrones
Game of Thrones Season 7 is in full flow and there have been more articles analysing the data as well.
Enter our Game of Thrones competition
Joakim Skoog has created an API of ice and fire, which contains data from all the books and TV episodes. The API was even featured in an article in the Washington Street Journal. If you want to do your own analysis this is the best place to start.
Tomaž Bratanič makes immediate use of the new graph algorithms library to try and figure out what’s going on in our favourite imaginary world. Tomaž shows how to use various algorithms to analyse the strength of each House.
Michael Hunger has also been busy playing with the dataset and shows how to make the GoT dataset available through a GraphQL endpoint.
And if you’re as much of a Game of Thrones enthusiast as us don’t forget to register for our Graph of Thrones online meetup on Thursday, August 17, 2017 at 16:00 UTC.
Online Meetup: Neo4j Bolt Drivers Roundtable
In this week’s online meetup we hosted a Neo4j Bolt Drivers roundtable where Christophe Willemsen, Adam Cowley, and Jasper Blues joined Nigel Small and me to talk about their experiences building a driver or framework for Neo4j.
If there isn’t a driver for your language of choice and you wish there was, there’s some good advice on how to get started.
Our next online meetup is on Thursday, August 10, 2017 at 16:00 UTC. Marco Falcier and Alberto D’Este will present Neo4j Versioner Core – Versioning your Neo4j graph through entity-state model.
Fake News, GraphQL command line tools, GrapheneDB
- My colleague Nir Avrahamov wrote the first part of his series on Machine Learning, Graphs and the Fake News Epidemic. In this post Nir outlines the problem of fake news around the US election and how a combination of machine learning along with a ‘news graph’ might be able to help combat it.
- In the theme of using Neo4j for security engineering, a post that David Vassallo wrote a few years ago – Getting started with Neo4J and security data analysis – resurfaced this week. In the post David shows how to create a graph based on the firewall logs from a server to see who’s trying to attack it and whether there are any vulnerabilities that need addressing.
- Adam Cowley shows how to turn a user story into a Cypher query using the compromise NLP library
- Ricky Brown created the graphenedb project which provides a thin Ruby layer around the GrapheneDB API.
- Earlier in the week Graphcool released graphql-cli – The Swiss Army Knife for your GraphQL Project, and Michael gave it a try with his Game of Thrones GraphQL backend.
- Ali Habib shared his dissertation – AutoReco: A Graph Database Driven Car Marketing and Recommendation System – in which he builds and evaluates an online car marketing system. Ali uses Christophe Willemsen’s graph4php library as part of the project.
Graph databases vs Relational databases
There were a couple of articles comparing and contrasting graph databases and relational databases this week.
Anupama Natarajan focused more on the use cases where each database excels, while Joe Swanson and Gian Luis Delgado compare the two with a product catalog example in Graph Databases: Connecting the Dots.
If you have a background in relational databases and want to get into graphs, I’ll be presenting a webinar RDBMS to graphs on Thursday, August 10th at 10.00 BST.
Tweet of the Week
My favourite tweet this week was by Songlink:
Don’t forget to RT if you liked it too.
That’s all for this week. Have a great weekend!
