What the data for this category looks like
The advanced chemical materials sector sources its policy and regulatory basis data primarily from industry specifications and industrial policy announcements issued by the Ministry of Industry and Information Technology and the National Development and Reform Commission, as well as group standards released by the China Chemical New Materials Industry Association. Data updates occur irregularly, aligned with the release schedule of official policies. Most single policy documents are structured text spanning thousands of characters, containing fields such as policy document number, issuing authority, effective date, applicable sub-categories, and core restrictive clauses. Clauses are divided by chapter numbering. Some supporting documents include quantitative indicators and unit specifications.
What constraints these characteristics impose on workflow orchestration
The long-text structure of advanced chemical materials policy documents requires retrieval nodes in the workflow to support precise recall based on fields such as document number and effective date. This prevents interference from irrelevant clauses. Policy data from multiple sources requires cross-knowledge base association logic to be configured during orchestration. This ensures coverage of compliance documents from different channels, including the Ministry of Industry and Information Technology and industry associations. The irregular update rhythm requires a scheduled synchronization trigger node to be embedded in the workflow. This stops expired policy content from being used. Additionally, some policies include quantitative unit requirements. The workflow must retain unit information from original fields to avoid unit confusion during retrieval.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Select Knowledge Base | Bind corresponding knowledge bases by classification: Ministry of Industry and Information Technology, industry associations | Sources of advanced chemical materials policies are scattered. Classified binding enables precise recall of compliance documents from target channels |
| Global Variable Configuration | Dynamically assign the knowledge base identifier in variables | Adapts to knowledge base switching needs for different policy Q&A scenarios, no repeated workflow modification required |
| Text Extraction Node | Extract fields by policy document number and effective date | Matches structured fields of advanced chemical materials policy documents, facilitating subsequent precise retrieval |
| Workflow Node Identifier | Bind nodeId to the corresponding workflow node | Ensures accurate invocation of each node in the workflow, avoids node confusion |
| Cyclic Trigger | Trigger at 0:00 daily | Adapts to the irregular update rhythm of policies, regularly synchronizes knowledge base content |
| Maximum Context | 8000–12000 characters | Covers the complete core content of a single policy document, avoids truncation of critical clauses |
Three common misconfigurations
- Symptom: The workflow runs with an empty knowledge base field in global variables, returning no matching results. Cause: The dynamic assignment logic for
variablesis not configured correctly. Only a single knowledge base identifier is hard-coded, which cannot support multi-channel policy retrieval needs. - Symptom: The workflow cannot complete cyclic verification of multiple policy clauses and terminates directly. Cause: Cyclic trigger configuration is not enabled, or the cyclic condition is not bound to the chapter field of policy clauses. This prevents traversal of complete document content.
- Symptom: Content returned by the text extraction node includes irrelevant paragraphs, and does not precisely match the policy document number. Cause: No extraction rule based on the policy document number field is configured. Only full-text retrieval is used, leading to recall of content from non-target policies.
How to verify successful configuration
- Manually trigger the workflow, select knowledge bases from different policy channels, and check if returned results correspond to policy content from the target channel.
- View the workflow's node logs to confirm that the knowledge base identifier in
variableshas been loaded correctly, with no null value errors. - Trigger the cyclic trigger node, check if knowledge base content is automatically synchronized according to the set cycle.
- Input a query containing a policy document number, confirm that the text extraction node can precisely recall the corresponding clause content.
