Enterprise Knowledge Graph Data for LLM Grounding and Training
Quick answer
Enterprise knowledge graph data for LLMs is a set of typed entities, relations and an ontology derived from real business systems (CRM, ERP, ticketing, product catalogs), with provenance recorded for every fact. Buyers use it to ground assistants in facts a model cannot guess, to train and evaluate KG-completion and entity-linking models, and to test ontology learning. Public graphs such as Freebase or DBpedia derivatives are encyclopedic, so they rarely reflect how a company actually links customers, contracts, parts and incidents.

Why public knowledge graph benchmarks do not cover enterprise use
Public KG benchmarks measure encyclopedic knowledge, not the schema-heavy, sparse and time-bound graphs inside a business. KG-completion papers still report results on graphs such as FB15k-237-IMG and DB15K [3], which hold people, places and films with dense, well-curated links. An enterprise graph looks different: few relation types repeated millions of times (customer placed order, order contains SKU, SKU supplied_by vendor), long-tail entities that appear once, and facts that expire when a contract ends.
Researchers describe the combination of LLMs and enterprise KGs as a way to improve language understanding, with tasks that include entity linking and enriching or completing the graph [1]. Work on large ontology models goes further and treats constructing, aligning and reasoning over enterprise ontologies as a learning problem in its own right [2]. Both lines of work need real enterprise schemas and instance data to be credible, which is why buyers look beyond public dumps. The Tabular, Time-Series and Transactional Data buyer's guide covers the wider structured-data landscape that these graphs are built from.
What an enterprise knowledge graph dataset should contain
A usable enterprise KG dataset has four layers: an ontology, entity records, relation triples and per-triple provenance. Missing any one of them limits what you can train or evaluate.
- Ontology (TBox). Classes, relation types, domain and range constraints and cardinalities, ideally in OWL or as a documented property graph schema, plus a SHACL shapes file or equivalent so you can validate instances.
- Entities (ABox nodes). Stable surrogate IDs, class, canonical label, aliases and source-system keys mapped to tokens. Aliases matter for entity linking.
- Triples or edges. Subject, predicate, object, with valid-from and valid-to dates so the graph supports temporal questions ("who was the account owner in Q2?").
- Provenance. For each triple, the source system, table or document, extraction method (system join, rule, NLP extraction, human curation) and a confidence value. W3C PROV-O gives a standard vocabulary for this, including
prov:wasDerivedFromandprov:wasGeneratedBy[4].
Ask for the graph in a format your stack reads natively: N-Triples or Turtle for RDF stores, CSV node and edge files for Neo4j or similar property graph imports, or Parquet edge lists for training pipelines. Ask also for the data dictionaries behind the source tables; the guide to data dictionaries and schema documentation as grounding data explains why those descriptions often carry more meaning than the column names.
How business systems become triples
The most reliable enterprise graphs are derived from system keys, not extracted from prose. A foreign key from order.customer_id to customer.id is an explicit relation with near-perfect precision. Text extraction from tickets or contracts adds coverage but also noise, so you need to know which edges came from which method.
Typical derivations a supplier can describe:
- CRM: account has_contact, opportunity for_account, opportunity includes_product.
- ERP: purchase order issued_to vendor, invoice settles purchase order, material component_of bill of materials.
- Service desk: ticket about_asset, ticket duplicate_of ticket, incident caused_by change request.
- Engineering records: service depends_on service, commit fixes issue.
Cross-system edges are the hard part. Linking a CRM account to an ERP customer requires entity resolution, and those match decisions should arrive as labeled edges with their own provenance. See entity resolution training data from real master data and packaging linked records from multiple business systems for how to specify the join keys and match labels.
Matching the graph to your training or grounding task
Different KG tasks need different slices of the same graph, so specify the task before you specify volume. The table below maps common uses to what you should request.
Illustrative example: invented to show structure; it does not describe an available dataset.
| Task | What to request | Split and evaluation notes | Common failure mode |
|---|---|---|---|
| KG-grounded RAG for an assistant | Ontology, entity labels and aliases, triples with validity dates, linked source documents | Question set whose answers require multi-hop traversal; gold paths recorded | Stale facts served because valid_to was dropped |
| KG completion (link prediction) | Triples with provenance; known-negative edges where the business confirms absence | Split by time or by entity, not random triples, to avoid inverse-relation leakage | Inflated scores from test triples whose inverse sits in train |
| Entity linking | Alias tables, mention text from tickets or notes, gold entity IDs | Hold out whole entities to test unseen-entity linking | Tokenized names make string-matching baselines look artificially strong or weak |
| Ontology learning and alignment | Two or more source schemas plus the curated target ontology and mapping file | Score mappings against curated alignments | Ontology given without instance data, so constraints cannot be tested |
| Text-to-graph-query (SPARQL or Cypher) | Natural-language questions, gold queries, expected result sets | Separate schema versions for evaluation | Gold queries that only run on the supplier's private endpoint |
For graph-query generation, the same discipline applies as in text-to-SQL training data from real enterprise schemas: execution-checked gold answers matter more than raw question counts.
Rights, permitted use and confidential relationships
Knowledge graph data concentrates commercially sensitive relationships, so rights review and use limits deserve more attention than for a flat table. A customer list or a supplier network can reveal a company's whole commercial position even after personal names are removed. Enterprise-ready datasets, in market practice, carry a documented source, permitted usage, licensing terms and restrictions [6].
Three questions decide whether a graph is usable:
- Grounding or training? Serving facts at inference time and training weights on them are different permissions. The comparison of a grounding license versus a training license sets out what each typically covers.
- Which relationships are confidential? Customer-to-product and supplier-to-part edges are often aggregated (counts per segment), tokenized (stable pseudonymous IDs) or suppressed below a threshold. Agree the treatment per relation type, not per file.
- Can policies travel with the data? The W3C ODRL model can express permissions, prohibitions and constraints in machine-readable form [5], which helps when graph edges carry different use restrictions.
Graphs also raise linkage risk that tables hide. A pseudonymized contact node connected to a job title, a small account and a single support ticket may be identifiable through its neighborhood. Regulator guidance stresses assessing identifiability against the means reasonably likely to be used, including linkage with other data [7]. Where the graph includes protected health information from a HIPAA covered entity or business associate, de-identification must meet Safe Harbor or Expert Determination under 45 CFR 164.514 [8].
Buyer checklist for an enterprise KG request
A precise request describes the data, the task and the controls, not a target company. Use this as a starting template.
Illustrative example: invented to show structure; it does not describe an available dataset.
kg_request:
task: kg_grounded_rag # or link_prediction, entity_linking, ontology_alignment
domain: B2B industrial distribution
source_systems: [CRM, ERP, service_desk]
ontology:
format: OWL (Turtle) + SHACL shapes
must_include_relations: [placed_order, contains_sku, supplied_by, about_asset]
instances:
format: N-Triples or CSV nodes/edges
temporal_fields: [valid_from, valid_to]
history_window: "multi-year preferred"
provenance:
vocabulary: PROV-O
per_triple: [source_system, source_table, method, confidence]
privacy:
person_nodes: tokenized_stable_ids
confidential_edges: aggregate_or_tokenize # customer lists, supplier networks
evaluation:
split: by_time_and_entity
gold_questions_with_paths: true
use: training_and_grounding # state both if both are needed
Before signing, check that every relation type in the ontology has instances, that referential integrity holds across node and edge files, and that the provenance field is populated rather than defaulted. The validation checks for structured dataset deliveries page lists schema, missingness and referential-integrity tests you can run on arrival. Teams comparing this with document corpora should note that a knowledge base of articles and a knowledge graph are different deliverables.
How SourceX approaches enterprise relationship data
SourceX sources operational datasets from US companies on request and manages the commercial process, including licensing agreements and ongoing purchases. Relevant source data can include support and sales histories, engineering records, documents and finance and legal workflows; categories are not inventory, and a request does not guarantee a match. Buyers describe the data they need, SourceX looks for US businesses that hold it, and every release is approved by the supplying company.
The process runs Find, Assess (data and licensing permissions), Agree (pricing and allowed uses in a license), Transact and Manage, and nothing is contracted until a supplier agrees. Every dataset is rights-reviewed for ownership and consents and delivered under a license that defines records, uses, term and delivery. Personal details such as names, emails, phones and account numbers are removed or replaced before delivery, the method is recorded and a sample is checked, though no method is perfect. You can start by describing your graph requirements on the SourceX buyers page.

Frequently asked questions
Is a knowledge graph better than plain RAG over documents?
They solve different problems. Document retrieval-augmented generation handles open questions over prose, while a graph answers multi-hop and aggregate questions about entities reliably. Many teams combine them, which is why the RAG evaluation datasets from real company documents page is a useful companion.
Should I buy the ontology without instance data?
Usually not for training. An ontology alone supports schema alignment research [2], but grounding and completion tasks need instances, provenance and validity dates.
How should I split a KG for link prediction?
Split by time or by entity rather than by random triple. Random splits can leak inverse and duplicate relations into the test set and inflate scores; public completion benchmarks such as FB15k-237-IMG are not built from enterprise graphs, so they will not reveal this for your data [3].
