Knowledge graphs in business
Give AI the connections behind the facts.
A knowledge graph is a connected map of what an organization knows: people, companies, products, contracts, events, documents and the relationships between them. It helps AI find not only a fact, but also its business context, supporting evidence and source.
Shared business meaningDefine what the business means with an ontology.
An ontology is an agreed description of the important concepts in a business domain—such as customer, supplier, contract, product and obligation—and the relationships and rules that connect them.
Ontology design is the work of deciding those names, definitions, categories, properties and valid relationships. This is crucial because different departments and systems may use the same word differently, or different words for the same thing. The ontology gives the knowledge graph and AI a shared language, so information extracted from many sources can be classified consistently and interpreted with the intended business meaning.
Searchable enterprise knowledgeBetter answers with GraphRAG.
A general-purpose large language model such as ChatGPT or Claude does not automatically have access to an organization’s private data. RAG—retrieval-augmented generation—is a way to make approved enterprise information searchable and give the most relevant results to the model when someone asks a question. Instead of responding only from its general training, the model can work with the organization’s own contracts, policies, reports and operational records. This allows people to search, compare, summarize, analyze and reason over enterprise information through a natural-language conversation.
A knowledge graph adds the relationships behind that information. Rather than returning only passages containing similar words, the system can follow how a supplier connects to contracts, products, plants and customers, then retrieve the relevant evidence. This connected approach is called GraphRAG. It can produce more complete, relevant and traceable answers because it retrieves both the information and the business context linking it together.
Memory & contextHelp AI agents understand the situation.
An AI agent is software that can plan and carry out a bounded, multi-step task using approved tools—for example, investigating a case, checking records and preparing a recommendation.
A knowledge graph can provide persistent memory and current context: what the agent already knows, how people and events are connected, which evidence supports a conclusion and which permissions apply. This helps an agent maintain continuity across steps instead of treating every action as an isolated prompt.
Cause, effect & interventionMake causal reasoning more explicit.
Causal AI goes beyond finding patterns that move together. It asks what may influence an outcome and what could happen if the organization changes a policy, process or intervention.
A knowledge graph can represent dependencies, events, assumptions and evidence in a form people can inspect. It does not prove causation by itself, but it gives causal analysis a clearer structure and makes the reasoning easier to examine and challenge.
Documents, archives & scaleTurn historical information into connected knowledge.
Contracts, reports, case files, correspondence and archives contain valuable knowledge that is difficult to search as a whole. AI-assisted extraction can identify entities—such as people, organizations, products and events—and the relationships between them, while retaining links to the original sources.
With appropriate identity resolution, modeling and indexing, the resulting graph can contain millions of entities and still support efficient access to the relevant connected information. Neo4j supports both sides of this process: building graphs from unstructured documents and using graph, full-text and vector indexes for retrieval.
Graph database & analytics platformStore, query and analyze connected data with Neo4j.
Neo4j is a graph database designed to represent entities as nodes and their connections as relationships. Instead of repeatedly joining separate tables, applications can follow connected paths directly—for example, from a supplier to its contracts, products, factories, shipments and affected customers.
Neo4j provides the Cypher graph query language, data constraints, relationship traversal, exact and full-text search, vector search for semantic similarity, graph algorithms and GraphRAG tooling. These capabilities support fast connected-data access, network analysis, explainable discovery, AI agents and enterprise applications operating across large graphs.
