How to query your graphs with CoPilot
CoPilot (InquiryAI) can answer your questions by calling installed GSQL queries or built-in functions. The following built-in functions are supported:
-
getEdgeCount
-
getEdgeCountFrom
-
getEdgeStats
-
getEdges
-
getVertexCount
-
getVertexStats
-
getVertices
-
getVerticesById
-
tg_bfs
-
tg_pagerank
-
tg_shortest_ss_no_wt
To make your own installed queries available to CoPilot, you need to “register” them with CoPilot. This can be done by using a REST API or pyTigerGraph.
Register Installed Queries
REST HTTP Endpoints
Register a query by sending information about the query to the /{graphname}/register_docs
endpoint. The body of the request should contain the following information:
[{
"function_header": "string",
"description": "string",
"docstring": "string",
"param_types": {},
"graphname": "all"
}]
-
function_header
: Name of the query. -
description
: Human readable description. Optional. -
docstring
: Detailed description of the query used by CoPilot (i.e., the LLM) to determine what this query does and what it requires, in order to select which query to invoke and to invoke it correctly, to answer a question. -
param_types
: Name and type of every parameter of the query
The docstring
field is especially important.
It should contain enough information for the LLM to understand the purpose of this query while being concise and distinctive from other queries’ descriptions.
You may need to tune this string if CoPilot is not selecting this query to answer a question when it seems that it should.
pyTierGraph
pyTigerGraph provides a convenient function registerCustomQuery
to register your GSQL queries.
Please see its documentation for details or this notebook as an example.
Query
Now, we can ask questions in natural language, and CoPilot will run the relevant query or function to answer them.
If you use the API method, you can send your question to InquiryAI directly. Send a REST request to the /{graphname}/query
endpoint, where a request body contaisn your question in the following format:
{
"query": "YOUR QUESTION",
}
For pyTigerGraph, you can submit the question to the function query().
If you are on the chat interface, once you submit your question, CoPilot will determine the best way to answer your question: running installed queries or searching the knowledge graph.
