9 min read

Have you ever wondered how to make sense of the complex relationships in your data? How to solve a complex crime with multiple data sources, uncover complex financial fraud, or the optimal routes for delivery trucks? Graph analytics, a powerful technique, can help you uncover hidden patterns and insights from your data.

What is Graph Analytics?

Graph analytics, also known as graph algorithms, are analytic tools that can measure and explore the connections between objects in a graph. A graph is a data structure that consists of nodes (entities) and edges (relationships) between them. For example, a graph of a co-offending criminal network might have nodes representing people and edges representing phone numbers, accounts, or messages.

Graph analytics can reveal information that is not easily accessible from traditional analytics methods, such as:

  • Centrality analysis: the importance or influence of nodes in a network, based on the number and quality of their connections.
  • Similarity analysis: the similarity or relatedness of nodes in a network, based on their attributes or shared connections.
  • Community analysis: the community or group structure of a network, based on the density or modularity of the connections.
  • Link prediction: the probability of shared links between entities, based on the their attributes and mutual connections.


Graph analytics is a powerful and versatile technique that can help you analyze and understand the complex relationships in your data. By using graph analytics, you can uncover hidden patterns and insights that can inform your decisions and actions. Graph analytics can be applied to various domains and use cases, such as social network analysis, fraud detection, recommendation systems, supply chain optimization, and more.

Graph analytics requires specialized tools and algorithms that can handle the complexity and scale of graph data, such as graph databases, graph visualization, and graph algorithms. Graph analytics is an emerging and fast-growing field that offers many opportunities and challenges for businesses and researchers.

Why is Graph Analytics Important for Big Data?

Graph analytics is important because it can handle the complexity and scale of big data, which often involves large, diverse, and dynamic datasets that are interconnected and interdependent. Analysts have to search through many different systems, then try to integrate the data manually, every time. Consider that intelligence analysts going through a 32GB iPhone may have to dig through 7-8GBs of data. This is time consuming, error-prone, and may miss important connections.

Graph analytics can help:

  • Integrate and harmonize data from multiple sources and formats, such as structured, unstructured, or semi-structured data.
  • Analyze data in real time, enabling faster and more accurate decision making and action taking.
  • Incorporate artificial intelligence and machine learning techniques, such as natural language processing, computer vision, or deep learning, to enhance the analysis and generate new insights.
How do Graph Databases and Graph Analysis Work Together?

Graph databases are not new - they’ve been around since the 1960s, and have been used for applications such as social networks, recommendation engines, fraud detection, and knowledge graphs. But they have gained popularity in recent years, thanks to the rise of big data, artificial intelligence, and the internet of things. One of the main advantages of graph databases is that they can handle highly connected data, which is becoming more common and valuable in the digital age.

Graph databases began entering workflows in the mid-1980s, as an alternative to traditional databases, and are commonly referred to as a NoSQL – a direct response to the SQL relational databases that arose in the ‘70s. They use graph structures for semantic queries with nodes, edges, and properties to represent and store data. They allow users to create, query, and manipulate graphs using graph models, such as property graphs or RDF graphs. Graph databases offer several advantages over traditional relational databases, such as:

  • They can represent complex and heterogeneous data more naturally and intuitively, without requiring rigid schemas or tables.
  • They can perform faster and more efficient queries, especially for traversing or joining data across multiple relationships, without requiring costly joins or indexes.
  • They can scale horizontally and vertically, supporting large and distributed graphs, without compromising performance or consistency.

Graph databases provide the foundation for graph analytics, as they enable users to apply various graph algorithms and techniques to the graph data. Some of the common types of graph analytics algorithms are:

Centrality algorithms: These algorithms measure the importance or influence of nodes in a graph based on their connectivity and position within the graph. They can help find the key players in a criminal network, or the bottlenecks or bridges in a graph. Community detection algorithms: These algorithms find groups or clusters of nodes in a graph that have more connections among themselves than with other nodes. They can help identify communities or subgroups of people with similar behaviours, characteristics, or regions or areas with similar properties or features. Similarity algorithms: These algorithms compare nodes in a graph based on some measures of similarity or distance, such as the number of common contacts, the length of the shortest path, or the angle or correlation between the nodes. They can help find patterns or trends in the data, for example possible criminal connections. Link prediction algorithms: These algorithms estimate the probability or likelihood of a link or edge forming between two nodes in a graph. They can help predict future interactions or relationships between nodes, such as identifying possible cyber or real-world attacks.

Relational databases are still relevant in managing data, yet are best-suited to keeping data transactions secure and promoting a high level of data integrity. Unfortunately, the very constraints that allow these benefits are the very reason they tend to struggle to adapt to domains with complex connected data.

With the data we collect becoming increasingly interconnected, graph databases offer infinite possibilities due to their flexibility, which can be leveraged as project or organization’s requirements change on-the-fly.

How do Graph Data Analytics Help Intelligence Agencies and Police?

Graph data analytics is a vital tool for law enforcement and intelligence agencies, as it enables them to analyze vast amounts of data and uncover hidden connections that can aid in investigations. For example, graph data analytics can help them:

  • Analysts may know that all data items are connected, but can’t simply relate them, even when they come from the same source. Hume, for example, exploits knowledge graphs to naturally store implicit and explicit connections among items coming from the same or multiple data sources.
  • Criminal intelligence requires searching across multiple heterogenous data sources and finding matches to support evidence. The knowledge graph model acts as a uniform single source of intelligence overcoming the heterogeneity of the original data sources.
  • Considering the amount of data just a single each device (phone, tablet, pc, etc.) contain, and, in general, the amount of data accessible for each investigation (traffic videos and images, cellular towers, digital reports, etc.), it isn’t realistic to expect officers or police staff always to do it manually. Hume Orchestra provides the tools to read data from multiple sources and organise in a single or multiple graph, to solve cases from financial fraud to uncovering terrorist networks.
  • For a single case, analysts have to search across multiple Excel files and manually identify connections. This takes time and effort without assuring good and reliable results. Visualization allows analysts to find relevant information across all available data sources and bring them to the canvas where it is easy to spot relationships among entities. In this way, identifying potential suspects or persons of interest in high-volume crime, such as theft, burglary, or robbery, is made simpler by finding nodes that have similar or frequent relationships with the crime scenes or victims.

By using graph data analytics, law enforcement and intelligence agencies can enhance their capabilities and performance, solving complex and challenging cases faster and more effectively.
