Depending on your desired LM deployment, you will choose from one of the
following `Docker Compose` files:
-`docker-compose-azure.yaml`: AzureAI endpoint. Set `AZURE_TOKEN` to the secret token and
`AZURE_ENDPOINT` to the URL endpoint address for the deployed model.
-`docker-compose-claude.yaml`: Anthropic's API. Set `CLAUDE_KEY` to your API key.
-`docker-compose-ollama.yaml`: Local LM (currently using [Gemma2](https://ollama.com/library/gemma2) deployed through Ollama. Set `OLLAMA_HOST` to the machine running Ollama (e.g. `localhost` for Ollama running locally on your machine)
-`docker-compose-vertexai.yaml`: VertexAI API. Requires a `private.json` authentication file to authenticate with your GCP project. Filed should stored be at path `vertexai/private.json`.
**NOTE**: All tokens, paths, and authentication files must be set **PRIOR** to launching a `Docker Compose` file.
docker-compose -f docker-compose-claude.yaml up -d
```
#### Ollama Hosted Model Deployment
```
export OLLAMA_HOST=localhost # Set to hostname of Ollama host
docker-compose -f docker-compose-ollama.yaml up -d
```
#### VertexAI through GCP
```
mkdir -p vertexai
cp {whatever} vertexai/private.json
docker-compose -f docker-compose-vertexai.yaml up -d
```
If you're running `SELinux` on Linux you may need to set the permissions on the
VertexAI directory so that the key file can be mounted on a Docker container using
the following command:
```
chcon -Rt svirt_sandbox_file_t vertexai/
```
### Verify Docker Containers
On first running a `Docker Compose` file, it may take a while (depending on your network connection) to pull all the necessary components. Once all of the components have been pulled, check that the TrustGraph containers are running:
```
docker ps
```
Any containers that have exited unexpectedly can be found by checking the `STATUS` field
using the following:
```
docker ps -a
```
### Warm-Up
Before proceeding, allow the system to enter a stable a working state. In general
`30 seconds` should be enough time for Pulsar to stablize.
The system uses Cassandra for a Graph store. Cassandra can take `60-70 seconds`
to achieve a working state.
### Load a Text Corpus
Create a sources directory and get a test PDF file. To demonstrate the power of TrustGraph, we're using a PDF of the public [Roger's Commision Report](https://sma.nasa.gov/SignificantIncidents/assets/rogers_commission_report.pdf) from the NASA Challenger disaster. This PDF includes complex formatting, unique terms, complex concepts, unique concepts, and information not commonly found in public knowledge sources.
Output should be an array of JSON objects with keys `entity` and `definition`:
```
Indexing 1f7b7055-p11-c1...
[
{
"entity": "Orbiter",
"definition": "A spacecraft designed for spaceflight."
},
{
"entity": "flight deck",
"definition": "The top level of the crew compartment, typically where flight controls are located."
},
{
"entity": "middeck",
"definition": "The lower level of the crew compartment, used for sleeping, working, and storing equipment."
}
]
Done.
```
`Knowledge Graph Relationshps`:
```
docker logs trustgraph-kg-extract-relationships-1
```
Output should be an array of JSON objects with keys `subject`, `predicate`, `object`, and `object-entity`:
```
Indexing 1f7b7055-p11-c3...
[
{
"subject": "Space Shuttle",
"predicate": "carry",
"object": "16 tons of cargo",
"object-entity": false
},
{
"subject": "friction",
"predicate": "generated by",
"object": "atmosphere",
"object-entity": true
}
]
Done.
```
### Graph Parsing
To check that the knowledge graph is successfully parsing data:
```
scripts/graph-show
```
The output should be a set of semantic triples in [N-Triples](https://www.w3.org/TR/rdf12-n-triples/) format.
```
http://trustgraph.ai/e/enterprise http://trustgraph.ai/e/was-carried to altitude and released for a gliding approach and landing at the Mojave Desert test center.
http://trustgraph.ai/e/enterprise http://www.w3.org/2004/02/skos/core#definition A prototype space shuttle orbiter used for atmospheric flight testing.
```
### Number of Graph Edges
N-Triples format is not particularly human readable. It's more useful to know how many graph edges have successfully been extracted from the text corpus:
```
scripts/graph-show | wc -l
```
The Challenger report has a long introduction with quite a bit of adminstrative text commonly found in official reports. The first few hundred graph edges mostly capture this document formatting knowledge. To fully test the ability to extract complex knowledge, wait until at least `1000` graph edges have been extracted. The full extraction for this PDF will extract many thousand graph edges.
### RAG Test Script
```
tests/test-graph-rag
```
This script forms a LM prompt asking for 20 facts regarding the Challenger disaster. Depending on how many graph edges have been extracted, the response will be similar to:
```

For any errors with the `RAG` proces, check the following log:
```
docker logs -f trustgraph-graph-rag-1
```
### More RAG Test Queries
If you want to try different RAG queries, modify the `query` in the [test script](https://github.com/trustgraph-ai/trustgraph/blob/master/tests/test-graph-rag).
### Shutting Down
When shutting down the pipeline, it's best to shut down all Docker containers and volumes. Run the `docker compose down` command that corresponds to your model deployment:
