POLE with Neo4j
13
First - Express things the way they are:
● Add new concepts as they come up
● Don't generalize … for example what does linked to a crime
mean? That may serve as a stand-in, as soon as you know
better, express it that way!
Second - Leverage the relationships, the connections. That is where
the power of both the POLE mode and a graph database lies!
Lets bring the original (!) meaning of good enough for
government work back, shall we?

Demo - Location, location, location ...
16
● That is Cam Peak, Cotswolds, Dursley GL11 5HH, UK, latitude
51.690680, longitude -2.337421, MGRS 30U WC 45799 26843
● That is a public place
● That is a landmark
● An event took place there on May 29th, 2020 ...

Demo - The data
17
● The location is real
● The event and the story are real
● What I'm going to show is not real in the sense that it's not
literally being done like that … yet
● Names and addresses have been anomyzed

Takeaways
19
● A lot of governments have jumped on the exchange data bike,
on the making data publicly available bus, …
That is - without sarcasm - great
● Too few governments are on the high speed getting insights
from the data train, on the complex querying plane, on the
reacting in real time rocketship.
● The Neo4j database can help you do that!

This document discusses using Neo4j and graph algorithms for police investigations (POLE) based on a real-world crime dataset from Greater Manchester. It introduces the POLE data model and use cases, demonstrates Neo4j's advantages over other NoSQL databases for relationship queries, and shows sample visualizations of the crime graph data in Tableau and a custom web app. The presentation concludes by discussing ways to extend the demo dataset and tools to support a full-fledged investigative analysis platform.

Neo4j graphs in government

Neo4j

1) Governments can use graph databases to make their countries more secure, provide better services, and make government functions more efficient by leveraging connections in data. 2) Graph databases allow for analysis of connected data and detection of complex patterns across different domains like money laundering, law enforcement investigations, fraud detection, and national security. 3) Examples of how graph databases can be used include modeling money laundering networks, synchronizing law enforcement data, detecting fraud rings, and extracting insights from security and intelligence data involving people, locations, and events from multiple sources.

Ontology for Knowledge and Data Strategies.pptx

Mike Bennett

Ontology suffers from an adoption problem. If we are to describe the benefits of ontologies and knowledge graphs, we need to demonstrate how these can contribute to the business. That means addressing the knowledge and data management strategies of the organization. A knowledge management strategy addresses a range of concerns, including terminology, business semantics, data provenance and quality, information availability and a rigorous treatment of context. Ontology is just one tool among many in the overall strategy for managing knowledge assets and their use. In this seminar we will unpack the components of an organizational knowledge strategy and show in terms that both business and IT can understand, how different types of ontology fit in to the firm’s wider data management and knowledge strategies, alongside a range of other tools and techniques. Attendees do not need any prior knowledge of ontology, knowledge graphs or semantic technology, but should ideally have an appreciation of data and knowledge management issues. Mike Bennett's presentation on Ontology for Knowledge and Data Strategies, as presented at University of Westminster in December 2022. This covers how ontologies may be used as part of a broader business strategy for knowledge and data management, including how different styles of ontology are needed or different parts of such a strategy.

Improving Machine Learning using Graph Algorithms

Neo4j

Graph enhancements to AI and ML are changing the landscape of intelligent applications. In this session, we’ll focus on how using connected features can help improve the accuracy, precision, and recall of machine learning models. You’ll learn how graph algorithms can provide more predictive features as well as aid in feature selection to reduce overfitting. We’ll look at a link prediction example to predict collaboration with measurable improvement when including graph-based features.

The document discusses Neo4j's graph data platform and graph data science capabilities. It provides an overview of Neo4j's tools for data scientists, machine learning workflows, algorithms, and ecosystem integrations. Examples are given of improved customer outcomes including increased fraud detection and better predictive models. The document also outlines new capabilities in algorithms, embeddings, machine learning pipelines, and GNN support.

How Graph Algorithms Answer your Business Questions in Banking and Beyond

Neo4j

This document provides an agenda and overview for a presentation on using graph algorithms in banking. The presentation introduces graphs and the Neo4j graph database, demonstrates sample banking data modeled as a graph, and reviews several graph algorithms that could be used for applications like fraud detection, including PageRank, weakly connected components, node similarity, and Louvain modularity. The document concludes with a demo and Q&A section.

Data Modeling with Neo4j

Neo4j

Neo4j is a powerful and expressive tool for storing, querying and manipulating data. However modeling data as graphs is quite different from modeling data under a relational database. In this talk, Michael Hunger will cover modeling business domains using graphs and show how they can be persisted and queried in Neo4j. We'll contrast this approach with the relational model, and discuss the impact on complexity, flexibility and performance.

Introduction: Relational to Graphs

Neo4j

Relational databases were conceived to digitize paper forms and automate well-structured business processes, and still have their uses. But RDBMS cannot model or store data and its relationships without complexity, which means performance degrades with the increasing number and levels of data relationships and data size. Additionally, new types of data and data relationships require schema redesign that increases time to market. A graph database like Neo4j naturally stores, manages, analyzes, and uses data within the context of connections meaning Neo4j provides faster query performance and vastly improved flexibility in handling complex hierarchies than SQL. Join this webinar to learn why companies are shifting away from RDBMS towards graphs to unlock the business value in their data relationships. Ryan Boyd, Developer Relations at Neo4j Ryan is a SF-based software engineer focused on helping developers understand the power of graph databases. Previously he was a product manager for architectural software, built applications and web hosting environments for higher education, and worked in developer relations for twenty products during his 8 years at Google. He enjoys cycling, sailing, skydiving, and many other adventures when not in front of his computer.

OCTO Technology

Par Christophe Breheret-Girardin (Coach Craft & Formateur @OCTO Technology) Afin de pallier les problèmes des architectures N-tiers, plusieurs alternatives ont émergé après les années 2000, dont l’architecture Hexagonale et la Clean architecture. Seulement, elles ne sont pas toujours bien comprises : pour expliquer l'une, certains utilisent parfois les termes de l'autre ; d’autres se basent sur des croyances plutôt que sur les publications d'origine. Et si nous comparions ces deux architectures pour lever le doute une fois pour toutes ?
