- Knowledge Graph Actions
Overview
The "Generate Research Questions" operation of the "AI Advice From Graph" resource in this node leverages the InfraNodus API to generate insightful research questions based on an existing knowledge graph. This graph represents interconnected ideas or data points, and the node uses AI to analyze content gaps and clusters within it to propose diverse and meaningful questions.
This node is beneficial for researchers, content creators, educators, or analysts who want to explore new angles, identify unexplored topics, or deepen their understanding of a subject represented by a graph. For example, a researcher could input a graph summarizing current literature on climate change and receive novel research questions highlighting underexplored areas.
Properties
| Name | Meaning |
|---|---|
| Graph Name | The name of the existing InfraNodus graph expert to use for generating questions. |
| Deep Thinking Mode | Whether to use more content gaps to generate diverse and deeper questions. Options: No, Yes |
| Request Mode | (Hidden) The type of AI request; preset to "question" for this operation. |
| AI Topics | (Hidden) Whether to generate AI topic names for graph clusters; default is true. |
| Discourse Optimization | (Hidden) Use parts of the graph that optimize discourse; default value is "develop". |
| Do Not Save Graph | (Hidden) Whether to save a new graph; default is true (do not save). |
| Add Graph Stats | (Hidden) Whether to add graph statistics to the response; default is true. |
| Include Graph | (Hidden) Whether to include the graph itself in the response; default is false. |
| Include Graph Summary | Whether to include the graph summary in the response. Options: No, Yes |
| Include Extended Graph Summary | Whether to include detailed information about gaps and keywords in the graph summary. Options: Yes, No |
| Model to Use | The AI model to use for generating questions. Options include Claude Opus 4.1, GPT-4o, GPT-5, Gemini variants, etc. |
Output
The node outputs JSON data containing the generated research questions derived from the specified InfraNodus graph. The output may also include:
- Graph statistics if enabled.
- The graph summary and extended summary detailing content gaps and keywords, depending on the selected options.
- Optionally, the graph data itself if requested.
No binary data output is indicated for this operation.
Dependencies
- Requires an active InfraNodus API key credential configured in n8n.
- Depends on the InfraNodus API endpoint at
https://infranodus.com/api/v1. - Uses specific AI models supported by InfraNodus for question generation.
Troubleshooting
Common Issues:
- Invalid or missing graph name: Ensure the graph name corresponds exactly to an existing InfraNodus graph.
- API authentication errors: Verify that the API key credential is correctly set up and has necessary permissions.
- Network or connectivity problems with the InfraNodus API endpoint.
- Unsupported or unavailable AI model selection.
Error Messages:
- Authentication failures typically indicate invalid or expired API credentials.
- "Graph not found" errors suggest the provided graph name does not exist or is inaccessible.
- Timeout or network errors require checking internet connection or InfraNodus service status.
