What this category of data looks like
Telecommunications engineering construction policies and regulatory references primarily come from official documents issued by the Ministry of Industry and Information Technology, Ministry of Housing and Urban-Rural Development, and provincial communications administrations. These documents include telecommunications engineering quality management measures, construction project approval specifications, construction safety regulations, and similar materials. Updates are issued immediately when new regulations are released, with no fixed cycle.
Each document follows a standardized structure with five fields: issuing document number, issuing authority, effective date, applicable scenario, and core clauses. The document number format is MIIT Notice [Year] XX No.. Effective dates use the YYYY-MM-DD standard format. Individual document lengths range from 1000 to 5000 characters.
What constraints these characteristics impose on the workflow orchestration link
Policy sources are scattered across multiple departments and regional levels. This requires the workflow to support dynamic matching of knowledge bases from different sources. Effective dates are strongly tied to project cycles. This requires the workflow to automatically filter valid policies that align with the project’s time range. Documents have relatively long content. This requires workflow nodes to have sufficient processing time and text parsing capabilities. Some policies contain region-specific clauses. This requires the workflow to dynamically adjust the retrieval scope using project location parameters passed externally.
Workflow orchestration must balance flexibility and accuracy to avoid invalid retrieval or return of expired policies.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale for This Setting |
|---|---|---|
| Knowledge Base Selection | Bind to the knowledge base ID passed via variables | Telecommunications engineering policies are scattered across documents from multiple departments and regions. Dynamic matching of knowledge bases for target scenarios via variables is required. |
| Single Search Limit | Top 6 entries | Individual telecommunications engineering policy documents have relatively long content. Six entries can cover the core regulatory requirements of a project, while avoiding redundant results. |
| Node Timeout Duration | 720 seconds | Policy documents generally have long lengths. Sufficient time is needed for retrieval and parsing, to avoid process interruptions due to timeout. |
variables Passed Parameters | Project location, project start date | Telecommunications engineering policies have differences across regions and time dimensions. External passed parameters are needed to accurately filter valid documents. |
| Result Filtering Rules | Only retain entries with effective dates later than the project start date | This ensures returned policies are valid regulatory references for the project execution cycle. |
Three common mistakes
- Symptom: Manually inserting HTML audio or video tags in a custom response node results in the interface still displaying plain text. Cause: FastGPT v4.17.0 disables rendering permissions for non-standard text tags by default. The policy Q&A scenario requires strict matching of official document formats, and the node’s HTML rendering configuration is not enabled.
- Symptom: Custom knowledge base parameters cannot be passed via the API when configuring a knowledge base search node. Cause: The
variablesexternal passing permission for the workflow is not enabled, and the knowledge base selection item is not bound to the passed variable. - Symptom: The document number and effective date fields returned by the text extraction node are empty. Cause: The dedicated field structure of telecommunications engineering policy documents is not matched, and extraction rules for the corresponding fields are not specified, leading to parsing failure.
How to confirm the configuration is complete
- Pass test project location parameters, check if the workflow automatically matches the telecommunications engineering policy knowledge base for the corresponding region.
- Trigger the workflow, then check if the returned results include policy clauses with effective dates that fit the project’s time range.
- Call the API to pass a custom project start date parameter, confirm that results dated earlier than this date are automatically filtered out.
- View the workflow node’s running logs, confirm there are no error messages such as timeouts or failed field extraction.
