Australian Government Interactive Functions Thesaurus (AGIFT) as a Neo4j knowledge graph with embeddings and dual edge types

AGIFT Graph

Australian Government Interactive Functions Thesaurus (AGIFT) as a knowledge graph with embeddings and dual edge types.

What it does

Fetches the full AGIFT vocabulary from the TemaTres API, builds a graph with structural hierarchy edges, generates embeddings (free local or Isaacus API), then creates semantic similarity edges between related terms.

TemaTres API ──►  Graph ──► Embeddings ──► Semantic Edges
  (AGIFT)        (PARENT_OF)     (384/512/768d)  (SIMILAR_TO)

Graph model

Two edge types with different weights for query-time flexibility:

Edge	Type	Weight	Description
PARENT_OF	structural	1.0	AGIFT hierarchy (L1 → L2 → L3)
SIMILAR_TO	semantic	0.5	Cosine similarity above threshold

Nodes carry DCAT-AP theme mappings for interoperability with European open data standards.

Quick start

Path A — Docker (zero config)

pip install agift-graph[all]
docker compose up -d          # starts Neo4j on localhost:7687
agift                         # fetches AGIFT, builds graph, embeds

Path B — existing Neo4j

pip install agift-graph[all]
export NEO4J_URI=bolt://my-server:7687
export NEO4J_USER=neo4j
export NEO4J_PASSWORD=mypassword
agift

The CLI reads env vars with sensible defaults (bolt://localhost:7687, neo4j/changeme) that match the included docker-compose.yml.

Path C — CogDB (embedded, no server)

CogDB is a persistent embedded graph database written in pure Python. No server process, no Docker — data is stored to local files.

pip install agift-graph[cogdb]
agift --backend cogdb                # stores graph in ./agift_cogdb_data/
agift --backend cogdb --cogdb-dir /path/to/data

The pipeline runs identically to Neo4j — same fetch, embed, and semantic edge stages. CogDB terms, edges, and embeddings are stored as triples with JSON property blobs. Set COGDB_DATA_DIR as an environment variable or pass --cogdb-dir to control the storage location.

Install extras

Install	What you get	Size
pip install agift-graph	Neo4j driver + fetch + graph build	Lightweight
pip install agift-graph[cogdb]	+ CogDB embedded graph backend	Small
pip install agift-graph[embeddings]	+ sentence-transformers + torch	~2 GB
pip install agift-graph[isaacus]	+ Isaacus API client	Small
pip install agift-graph[all]	Everything (Neo4j + CogDB + embeddings + Isaacus)	~2 GB

Embedding providers

Provider	Cost	Dimensions	Setup
local (sentence-transformers)	Free	384, 768	Nothing — runs on CPU
isaacus (kanon-2-embedder)	Paid	256–1792	Set API key in dashboard

The local provider uses all-MiniLM-L6-v2 (384d) or all-mpnet-base-v2 (768d). Models are downloaded on first run and cached.

Programmatic usage

from agift import run_pipeline

# Run the full pipeline with Neo4j (default)
run_pipeline(provider="local", dimension=384)

# Explicit Neo4j connection
run_pipeline(
    neo4j_uri="bolt://localhost:7687",
    neo4j_user="neo4j",
    neo4j_password="changeme",
    skip_embed=True,
)

# Use CogDB instead of Neo4j
run_pipeline(backend_type="cogdb", provider="local", dimension=384)

Configuration

Variable	Default	Description
NEO4J_URI	bolt://localhost:7687	Neo4j connection URI
NEO4J_USER	neo4j	Neo4j username
NEO4J_PASSWORD	changeme	Neo4j password
COGDB_DATA_DIR	agift_cogdb_data	CogDB storage directory
ISAACUS_API_KEY	(empty)	Isaacus API key (optional)

All other settings (dimension, provider, similarity threshold, semantic edge weight) are configured via the dashboard UI and stored in the graph backend.

Full Docker stack

The included docker-compose.yml runs Neo4j, the dashboard, and a cron worker:

docker compose up -d --build

Then open the dashboard at http://localhost:5050 and click "Full Pipeline" or "Graph Only".

Service	Port	Description
Neo4j Browser	7474	Graph database UI
Neo4j Bolt	7687	Database protocol
Dashboard	5050	Config, run controls, logs
Worker	—	Cron-scheduled pipeline runs

CLI usage

# Full pipeline (fetch + graph + embed + semantic edges)
agift

# Use CogDB instead of Neo4j
agift --backend cogdb
agift --backend cogdb --cogdb-dir /path/to/data

# Graph only (no embeddings)
agift --skip-embed --skip-semantic

# Local embeddings, 384 dimensions
agift --provider local --dimension 384

# Force re-embed all terms
agift --force-embed

# Custom similarity threshold for semantic edges
agift --threshold 0.65

# Faster run: skip alt label fetching
agift --skip-alt

# Dry run (fetch from API, no writes)
agift --dry-run

Publishing

This project uses a tag-based release workflow:

1. Update CHANGELOG.md with a new version entry
2. Run ./release.sh 0.2.0 (replaces version in pyproject.toml, commits, tags)
3. Push: git push origin main --tags

The GitHub Actions workflow will:

• Build and publish to PyPI
• Build and push Docker images to Docker Hub (deepcivic/agift-dashboard, deepcivic/agift-worker)
• Create a GitHub Release with the changelog entry

Secrets required in GitHub repo settings:

• DOCKERHUB_USERNAME and DOCKERHUB_TOKEN (repo-level secrets)
• PyPI trusted publishing is configured via OIDC (no secret needed)

Changelog

See CHANGELOG.md for version history.
