TL;DR. The process of automatically building structured representations of information as a graph, connecting entities and their relationships.

Technical Definition

The process of automatically building structured representations of information as a graph, connecting entities and their relationships.

How it works

Knowledge graph construction is vital for enhancing AI's ability to reason and retrieve information. It involves extracting entities, relationships, and attributes from unstructured text, then organizing them into a coherent graph structure. This structured knowledge can significantly improve LLMs by providing a grounded and factual context, reducing hallucinations, and enabling complex queries.

Related Concepts

• Knowledge Representation — How facts and relationships are encoded so a system can reason over them.
• Reasoning engine — A component of a software system that infers conclusions from existing knowledge using logical methods.
• Information Extraction (IE) — Automatically identifying and extracting structured information from unstructured or semi-structured text.
