What the Data for This Category Looks Like
The data sources for port and shipping policy and regulatory basis include official announcements from the Ministry of Transport Maritime Safety Administration, operation specifications released by direct port administrations, domestically translated documents of International Maritime Organization conventions, and internal management systems of port groups. There is no fixed cycle for data updates. Updates are synchronized immediately when new policies are released. Revoked policies are marked with their effective end dates. Documents follow standard official document formats, including document numbers, issuing units, release dates, applicable port scopes, core clauses, and attachment materials. Fields include policy number, effective start date, executing port area, charging standards (unit: yuan per standard container, yuan per ton), operation process requirements, and more.
What Constraints These Characteristics Impose on the Citation and Traceability Process
Policy documents contain clear document numbers and effective dates. The traceability process must accurately match these fields to avoid citing content without clear basis. The applicable scope of policies is limited to specific port areas. Port scope filtering conditions must be added during retrieval to prevent incorrect recall of cross-regional policies. There is no fixed cycle for policy updates. The knowledge base must be synchronized regularly, otherwise revoked policies may be cited. Some policies include attachment materials. The traceability process must support links to attachment content and clause positioning to ensure complete traceability information.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | Effective single-segment clauses of port policies are relatively long, so complete content must be retained for traceability display |
| Single search limit | Top 5–7 entries | The number of policies in the port sector is relatively concentrated. Too many entries will exceed the context window limit |
responseData | Include policy number, release date, applicable ports | The core traceability identifiers of port policies are document numbers and effective scopes. Corresponding fields must be explicitly returned |
detail | Enabled | Specific clause locations of the original policy must be returned. Only providing titles is insufficient for precise traceability |
| Knowledge base synchronization frequency | Triggered by policy release, maximum interval not exceeding 7 days | There is no fixed cycle for port policy updates. Synchronization must be performed timely to avoid citing invalid policies |
Three Common Mistakes
- Only displaying the policy citation list in responses without corresponding body content. Cause: The body return configuration corresponding to
responseDatais not enabled, and only policy titles and basic identifier fields are returned. - Being unable to select knowledge base citation-related variables in workflow nodes. Cause: The
responseDataswitch is not enabled in the knowledge base configuration, so the system does not generate callable citation variable fields. - Retrieval results not matching policy content for the current operating port. Cause: No port scope filtering rule is added to the retrieval conditions, leading to incorrect recall of cross-regional policies.
How to Confirm the Configuration Is Complete
- Initiate a test query related to port policies to verify whether the response includes traceability fields such as policy numbers and release dates.
- Enter the workflow variable configuration interface to confirm that callable fields related to knowledge base citations exist.
- Simulate adding a new port policy to verify whether the new policy is normally retrieved and recalled after knowledge base synchronization in FastGPT v4.17.0.
- Check the system logs to confirm that the number of returned retrieval entries matches the configured single search limit.
