What the data for this category looks like
Document data for advanced chemical materials mainly comes from enterprise R&D ledgers, industry standard documents, third-party test reports, patent literature, and compliance approval documents. The data update frequency is adjusted based on the R&D stage: weekly updates during lab-scale and pilot production stages, and daily synchronization during mass production stages. Document structures include modules such as raw material ratios, performance parameters, compliance clauses, and approval processes. Most fields carry professional units such as MPa, g/mol, and wt%. The length of individual documents varies significantly, ranging from a few pages of test reports to dozens of pages of R&D feasibility reports.
Constraints imposed on workflow orchestration
The decentralized sources of advanced chemical materials data require workflows to connect multiple data source nodes, covering different types of content such as R&D databases and compliance databases. The high-frequency update feature requires configuring scheduled synchronization nodes to ensure the latest data is used for document drafting. Differences in document length and structure require chunking parameters in the workflow to adapt to professional content of varying lengths, avoiding truncation of professional terms. Fields with units require configuring variable extraction rules in the workflow to accurately match the association between professional units and numerical values. The approval process for compliance documents requires embedding approval nodes to improve the control links of the workflow.
Configuration settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapts to the varying lengths of advanced chemical materials documents, from short test reports to long R&D reports |
| Overlap Length | 100–150 characters | Prevents professional terms from being truncated during chunking, preserving contextual relevance |
variables | Pass fields such as raw material grades, test batches, and compliance document numbers | Meets the needs of variable replacement and professional information filling during document drafting |
| Timeout Duration | 600 seconds | Adapts to the time required for parameter calculation and content reading when parsing chemical documents |
nodeId | Correspond to the actual ID of the document parsing node | Ensures accurate data flow paths in the workflow and avoids node call errors |
| User-Manual Knowledge Base Selection | Calibrated based on actual testing | Supports dynamic switching between different knowledge bases such as R&D databases and compliance databases |
Three common misconfigurations
- A document parsing node is configured, but the model cannot read uploaded files. The workflow status shows "file parsing failed" with no output. The cause is that no file path mapping parameter is configured in
variables, causing the node to fail to locate the uploaded chemical documents. - Database connection tools throw errors when using variables. SQL execution works normally manually, but the console returns "parameter format mismatch" after variables are passed in. The cause is that professional chemical numerical values such as purity percentages are not converted to string format when passed to variables, leading to database parsing failures.
- Knowledge bases cannot be selected in real time during the conversation, and only a fixed knowledge base can be called when the workflow runs. The cause is that no trigger node for user-manual knowledge base selection is configured, or the knowledge base call node is not bound to an optional knowledge base list.
How to confirm proper configuration
- Upload a single advanced chemical materials test report, start the workflow, and check whether the parsing node output includes complete raw material parameters and compliance clauses.
- Trigger the manual selection operation in the workflow test interface, and confirm that you can switch to the R&D knowledge base or compliance knowledge base.
- Pass preset
variablesparameters, and check whether the generated document correctly replaces the corresponding field content. - Run a workflow with multiple nodes, and confirm that there are no errors in
nodeIdcalls between nodes.
