|
||
|
||
`semantica.explorer` provides a browser-based dashboard for exploring knowledge graphs, managing ontologies, and running visual analyses — no code required.
|
||
|
||

|
||
|
||
## Installation
|
||
|
||
```bash
|
||
pip install "semantica[explorer]"
|
||
```
|
||
|
||
Requires `uvicorn` and `fastapi`. Included automatically with `pip install semantica[all]`.

|
||
|
||
## Launch
|
||
|
||
<CodeGroup>
|
||
|
||
```bash CLI
|
||
# Start the explorer on a saved graph
|
||
semantica-explorer --graph my_graph.json
|
||
|
||
# Custom host and port
|
||
semantica-explorer --graph my_graph.json --host 0.0.0.0 --port 8080
|
||
|
||
# Don't auto-open browser
|
||
semantica-explorer --graph my_graph.json --no-browser
|
||
```
|
||
|
||
```python Python
|
||
from semantica.context import ContextGraph
|
||
from semantica.explorer import start_explorer
|
||
|
||
graph = ContextGraph(advanced_analytics=True)
|
||
# ... build or load your graph ...
|
||
graph.save("my_graph.json")
|
||
|
||
# Launch the dashboard
|
||
start_explorer(graph_path="my_graph.json", port=8000)
|
||
```
|
||
|
||
```python Module
|
||
# Run directly as a Python module
|
||
# python -m semantica.explorer --graph my_graph.json --port 8000
|
||
import subprocess
|
||
subprocess.run(["python", "-m", "semantica.explorer", "--graph", "my_graph.json"])
|
||
```

## Features
|
||
|
||
### Graph Explorer
|
||
|
||
The core dashboard for navigating knowledge graphs:
|
||
|
||
- **Indexed search** — find any node by label or type; 0.004ms on 118k-node graphs
|
||
- **Bidirectional path finding** — trace paths between any two nodes
|
||
- **Neighbor expansion** — click any node to expand its connections
|
||
- **Filter by entity type** — focus on specific node types (Person, Organization, Event, etc.)
|
||
- **Edge label display** — relationship types shown on all edges
|
||
- **Graph declutter** — workspace layout controls for dense graphs
|
||
|
||
### Ontology Hub (v0.5.0)
|
||
|
||
Full ontology lifecycle management in the browser:
|
||
|
||
- **Visual ontology editor** — drag-and-drop class and property authoring
|
||
- **SHACL Studio** — create, validate, and test SHACL shapes with live feedback
|
||
- **Alignment authoring** — author ontology alignments across schemas
|
||
- **Health dashboard** — graph quality metrics, validation status, coverage reports
|
||
- **Version control** — snapshot, diff, and restore ontology versions
|
||
|
||
### Distance Intelligence (v0.5.0)
|
||
|
||
Semantic neighborhood analysis:
|
||
|
||
- **N×N distance matrices** — pairwise semantic distances across node sets
|
||
- **Ego-mode visualization** — focus on a single node's semantic neighborhood
|
||
- **Distance band classification** — nodes grouped as `near` / `mid` / `far`
|
||
- **Embedding cache** — optimized embedding reuse for large graphs
|
||
|
||
### Knowledge Explorer API
|
||
|
||
Full FastAPI backend accessible at `http://localhost:8000/docs`:
|
||
|
||
- 12+ export formats (RDF, Parquet, AQL, JSON-LD, and more)
|
||
- WebSocket progress streaming for long operations
|
||
- Thread-safe sessions with rollback protection
|
||
- Audit trail for all operations
|
||
|

|
||
|
||
## API Endpoints
|
||
|
||
The FastAPI server exposes a REST API alongside the browser dashboard:
|
||
|
||
| Endpoint | Method | Description |
|
||
|----------|--------|-------------|
|
||
| `/api/graph/summary` | `GET` | Node count, edge count, entity types |
|
||
| `/api/graph/search` | `GET` | Full-text and type-filtered node search |
|
||
| `/api/graph/path` | `GET` | Bidirectional path between two nodes |
|
||
| `/api/graph/neighbors` | `GET` | Neighbors of a node with optional depth |
|
||
| `/api/ontology/validate` | `POST` | Run SHACL validation on the graph |
|
||
| `/api/export/{format}` | `GET` | Export graph in specified format |
|
||
| `/ws/progress` | `WS` | WebSocket stream for operation progress |
|
||
|
||
Full OpenAPI docs available at `http://localhost:8000/docs` when the server is running.
