Geocoding Paradise Papers Addresses In Neo4j To Build Interactive Geographical Data Visualizations

Geocoding Paradise Papers Addresses In Neo4j To Build Interactive Geographical Data Visualizations

November 28, 2017 • 12 min read

This post explores how to build spatial data visualizations using address data from the Paradise Papers leak of offshore corporations and the people connected to them. First, we geocode all addresses in the leaked data, then build a heatmap and interactive map for exploring the data of offshore legal entities.

Applying NLP and Entity Extraction To The Russian Twitter Troll Tweets In Neo4j (and more Python!)

Applying NLP and Entity Extraction To The Russian Twitter Troll Tweets In Neo4j (and more Python!)

November 15, 2017 • 10 min read

Natural language processing (NLP) techniques like entity extraction can be used to help make sense of a large text corpus. In this post we apply named entity resolution to the scraped Russian Twitter Troll tweets to try to get a better understanding of how these trolls were spreading fake news.

Analyzing A Local Startup Ecosystem With Mattermark, GraphQL, Apollo Client, and Neo4j

Analyzing A Local Startup Ecosystem With Mattermark, GraphQL, Apollo Client, and Neo4j

April 27, 2017 • 13 min read

Many web services are converting their publicly facing APIs from REST to GraphQL. Companies like GitHub and Shopify have been leading this transition to GraphQL. In this post we take a look at how we can query the new Mattermark GraphQL API using Apollo Client, storing the results in Neo4j to then see what we can learn about a local startup ecosystem.

Combining The BuzzFeed Trumpworld Graph with Government Contracting Data in Neo4j

Combining The BuzzFeed Trumpworld Graph with Government Contracting Data in Neo4j

January 30, 2017 • 13 min read

One of the powers of working with graph databases is the ability to combine disparate datasets and query across them. Today we will look at how we can combine the BuzzFeed Trumpworld graph with data about federal government contracts from USASpending.gov, allowing us to examine any government contracts that were awarded to organizations that appear in Trumpworld.

Crawling APIs Using Neo4j - Building The Star Wars Graph

Crawling APIs Using Neo4j - Building The Star Wars Graph

December 14, 2015 • 2 min read

A common task when working with data from APIs is crawling the API and inserting the results in a database. In this example we will import data into Neo4j by crawling a public API, building a graph in Neo4j as we go along. We will use Neo4j as a queuing mechanism to store URLs for placeholder resources waiting to be fetched.

October 11, 2015 • 12 min read

This post shows how we can apply graph analytics to US Congressional data to find influential legislators in Congress. Using the Mazerunner open source graph analytics project we are able to use Apache Spark GraphX alongside Neo4j to run the PageRank algorithm on a collaboration graph of US Congress.

Introducing legis-graph - US Congressional Data With Govtrack and Neo4j

Introducing legis-graph - US Congressional Data With Govtrack and Neo4j

September 20, 2015 • 9 min read

Interactions among members of any large organization are naturally a graph, yet the tools we use to analyze data about these organizations often ignore the graphiness of the data and instead map the data into structures (such as relational databases) that make taking advantage of the relationships in the data much more difficult when it comes time to analyze the data. Collaboration networks are a perfect example. So we focus on one of the most powerful collaboration networks in the world, the US Congress.
