What the Data for This Category Looks Like
Port and shipping policy and regulatory basis data is primarily sourced from official public announcements and normative documents issued by the Ministry of Transport, directly affiliated maritime administrations, and coastal and inland port administrations across regions. Data updates are synchronized immediately when new industry regulations are released. Revised versions of existing documents are synchronized weekly on a routine basis. Each policy document is treated as an independent unit, with fields including document number, issuing authority, effective date, applicable port area, clause entries, supporting attachments, and more. Field units follow standard official document formatting uniformly. Applicable port areas are identified by specific port names or administrative divisions.
What Constraints These Characteristics Impose on Workflow Orchestration
The effective date and applicable port area fields of policy documents require the workflow to include time verification and port matching nodes. These nodes filter policies that are not yet effective, have been repealed, or cross-regional content that does not fit the current operational scenario. Individual policy documents have a large number of clauses and a fixed structure. When processing content in chunks, clause number associations must be retained to avoid losing contextual logic after slicing. The fixed format of official documents requires the workflow parsing stage to match standard document number and issuing authority verification rules, ensuring the authority of retrieved content.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Single Retrieval Limit | Top 10 entries | Port and shipping policy documents have a large number of clauses per file. Excessive retrieval will exceed the context length limit and cause content redundancy |
| Context Window | 8000–12000 token | Policy documents contain multi-clause associated content. Sufficient context must be retained to ensure logical coherence and avoid taking content out of context |
variables Binding | Bind port area name, current operational scenario | Match applicable port areas and operational scenarios of policies, filter invalid retrieved content, and improve accuracy |
| Node Timeout | 600 seconds | Policy document parsing and retrieval require reading multi-source official data. Reserve sufficient time for requests and processing |
| Reranking Switch | Enabled | Policy clause priority must be sorted by effective time and relevance to help quickly access core content |
Three Common Misconfigurations
- Workflow stops after reaching a tool call node, and the interface shows no valid return results. Cause: No port area parameter is bound via
variables, so the retrieval stage fails to match applicable policies, and no eligible content is returned. - Unable to open the online preview link of the original file from retrieval results. Cause: The workflow does not configure an original file path association node, only sliced text fragments are retrieved, and the storage identification information of the original document is not retained.
- Channel testing passes normally but tool calls in the workflow fail, returning a timeout error. Cause: The node timeout setting is too short. Batch read requests for official policy documents do not complete within the preset duration.
How to Confirm Proper Configuration
- Input a test question that includes a specific port area name and operational scenario, and check whether the retrieved results only include policy content applicable to that port area.
- View workflow node logs to confirm that the return duration of tool calls does not exceed the preset timeout threshold.
- Check whether the retrieved results include the storage path identifier of the original file, verifying that the original file preview link generation logic works correctly.
- Adjust the keywords of the test question to confirm that the workflow automatically matches the contextual content of corresponding policy clauses.
