The Foundation of Knowledge Graphs in AWS

Before diving into the intricacies of building a knowledge graph with AWS, it's crucial to grasp the fundamental principles of knowledge graphs and how AWS Neptune serves as the cornerstone for these sophisticated data structures. Knowledge graphs represent a revolutionary approach to managing and interpreting data, enabling a semantic understanding of diverse information sources through interconnected data points.

What is a Knowledge Graph?

At its core, a knowledge graph describes the connections between things much like our brains, taking facts and linking them in a meaningful way with related physical or logical concepts. In a knowledge graph, entities like people, places, objects, and concepts, are represented as nodes where each node stands for a unique entity. The connections or relationships between these entities are represented as edges.

AWS Neptune is a graph database that uses a graph-structured data model to store interconnected descriptions of entities—objects, events, or concepts—along with their interrelations. This graph structure facilitates a more nuanced and contextual understanding of data, allowing for intricate queries and analytics that traditional relational databases struggle to support efficiently.
