This Week in Neo4j – Pink Programming, Graph Visualization using Neovis.js, Analysing Debian Packages

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.

This week we have Graph Visualization using Neovis.js, a write up of the Pink Programming event, analysing Debian packages, and more.

This week’s featured community member is Norbert Preining, Research and Development Engineer at Accelia Inc.

Norbert has been using Neo4j to analyse the Ultimate Debian Database. In October 2017 he presented at our online meetup and showed how to write Cypher queries to explore dependencies between packages.

More recently Norbert has started a blog series where he goes into more detail:

    • Part 1 in which Norbert gives a short introduction to Debian and the life time and structure of Debian packages
    • Part 2 in which Norbert describes the Ultimate Debian Database UDD and shows how to map the information presented from the UDD into Neo4j.

You can also find Norbert’s code in the debian-graph GitHub repository.

On behalf of the Neo4j community, thanks for all your work Norbert!

Neo4j <3 Pink Programming

Last weekend my colleagues Louise Söderström and Maria Scharin hosted a Neo4j fundamentals workshop for the Pink Programming group.

Pink Programming at Neo4j

In the morning participants learned the basics of our query language Cypher and did some hands-on Cypher tutorials based on the Movies example database.

After lunch they got a sneak peek at the new date data type that will be introduced in Neo4j 3.4 and Louise explained all the weird corner cases when implementing support for dates, times and time zones.

On the podcast: Irene Iriarte Carretero

This week on the podcast Rik interviewed Irene Iriarte Carretero, Data Scientist at Gousto and our featured community member from 3rd March 2018.

Rik and Irene discuss the recipe-similarity problem and Irene explains all the different dimensions that go into building a hybrid recommendation model that combines collaborative and content based filtering.

Screencast: Graph Visualization With Neo4j Using Neovis.js

My colleague Will Lyon has created a screencast in which he shows how to use neovis.js, a visualization tool he built that combines Neo4j with the vis.js JavaScript library.

Will demonstrates how to find influential nodes and communities of users in the Russian Twitter Troll dataset by combining Graph Algorithms and Graph Visualization.
