HGR Knowledge Graph Triplet Dataset
Dataset Summary
The HGR Knowledge Graph Triplet Dataset is an instruction-tuning dataset for training language models to perform ontology-constrained knowledge graph extraction.
Given a passage of text, the task is to generate a structured set of triplets in the form:
source -> relation -> target
where:
sourcecontains an entity title and typerelationcontains a relation type and confidence weighttargetcontains an entity title and type
The dataset is designed for:
- Knowledge Graph Construction
- GraphRAG pipelines
- Relation Extraction
- Structured Information Extraction
- Entity Linking pipelines
- Document-to-Graph conversion

| Total Samples | 3,350 |
| Training Samples | 2,575 |
| Validation Samples | 75 |
| Test Samples | 700 |
| Relation Types | 20 |
| Hard Negatives | 392 |
| Schema Errors | 0 |

| Domain | Wikipedia + arXiv |
Motivation
Traditional instruction datasets for relation extraction often suffer from:
- inconsistent entity names
- unconstrained relation types
- missing confidence scores
- hallucinated relations
- outputs unsuitable for graph databases
This dataset was created specifically to train models that produce:
- ontology-constrained outputs
- normalized entity titles
- grounded triplets
- confidence calibrated relations
- graph-ingestable JSON
Corpus Sources
The corpus is collected from:
Wikipedia
General world knowledge including:
- People
- Concepts
- Organizations
- Scientific topics
- Historical events
arXiv
Scientific and technical literature including:
- Machine Learning
- Artificial Intelligence
- Computer Science
- Algorithms
- Research methods
Dataset Construction Pipeline
The dataset was built using a multi-stage pipeline.
1. Corpus Collection
Raw passages are collected from:
- Wikipedia
- arXiv
2. Quality Filtering
Passages undergo:
- Language filtering
- Length filtering
- Quality heuristics
Low-quality passages are discarded.
3. Deduplication
MinHash deduplication removes:
- Near duplicates
- Copy-pasted content
- Repeated paragraphs
4. Triplet Generation
Triplets are generated using:
DeepSeek V4-Flash
Each passage is converted into:
source -> relation -> target
triplets with:
- entity title
- entity type
- relation type
- confidence weight
5. Schema Validation
Generated outputs are validated against a fixed ontology.
Invalid:
{
"relation":"released"
}
Valid:
{
"relation":"used_for"
}
Only ontology-compliant triplets are retained.
6. Semantic Validation
Triplets are checked for:
- entity grounding
- relation consistency
- structural correctness
- semantic plausibility
7. Hard Negative Generation
The training split includes intentionally difficult negatives.
Examples:
- invalid entity pairs
- incorrect relations
- misleading but plausible connections
Hard negatives comprise:
392 examples (~15%)
and improve robustness against hallucination.
8. Curriculum Ordering
Training examples are ordered:
Easy → Medium → Hard
based on:
- triplet count
- entity complexity
- relation ambiguity
- semantic density
9. Train/Test Decontamination
Entity-level decontamination is performed before splitting.
This reduces:
- entity leakage
- memorization bias
- train-test contamination
Relation Ontology
The dataset contains exactly 20 relation types:
implements
trained_on
evaluates
part_of
introduces
extends
depends_on
contrasts_with
applied_to
measured_by
founded_by
developed_by
defined_as
consists_of
is_type_of
based_on
used_for
created_by
located_in
predecessor_of
Models trained on this dataset are expected to generate only these relations.
Data Format
The dataset follows a chat-style instruction tuning format.
Example:
Input
{
"messages":[
{
"role":"user",
"content":"Extract knowledge graph triplets from the following text..."
}
]
}
Output
[
{
"source":{
"title":"September",
"type":"entity"
},
"relation":{

"weight":0.92
},
"target":{
"title":"Gregorian calendar",

Intended Use
This dataset is intended for training models for:
- Knowledge Graph Extraction
- GraphRAG
- Relation Extraction
- Entity Linking
- Structured Information Extraction
- Ontology-Constrained Generation
Limitations
- English-only corpus.
- Fixed ontology of 20 relation types.
- Scientific and encyclopedic domains are overrepresented.
- Confidence scores are model-generated rather than human annotated.
- The dataset prioritizes schema correctness over exhaustive relation coverage.
