What the data for this category looks like
Shipping and port research report data mainly comes from public financial reports of global port operating institutions, public bulletins of the Ministry of Transport Water Transport Bureau, industry reports from the Baltic Exchange, and monthly operation announcements of port groups. Updates follow a monthly regular rhythm, with real-time supplementary releases for major events such as route adjustments and berth expansions. Document structures typically include core operation data, route updates, policy analysis, and market forecast modules. Fields include container throughput (unit TEU), number of berthing vessels (unit vessel trips), loading and unloading efficiency (unit containers/hour), and some reports have attachments such as high-definition berth floor plans and route freight rate curves, with a wide range of single-document word counts.
What constraints do these characteristics impose on workflow orchestration
First, there are two types of data update rhythms: regular and real-time. Workflows must support scheduled pulling and event-triggered incremental synchronization to avoid missing sudden port operation changes. Second, fields have specific units and business meanings. Information extraction nodes in workflows need unit validation rules to prevent unit confusion for throughput, loading and unloading efficiency data across different ports. Third, some reports include visual attachments. Workflows must integrate image parsing nodes, and cannot only handle plain text content. Fourth, single-document length varies widely. Flexible segment lengths must be configured to adapt to reports of different sizes. When batch processing reports for multiple ports, concurrency control must be set to avoid triggering rate limits of external data interfaces.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Shipping and port research reports often contain large numbers of charts and long text. Regular parsing duration exceeds basic configurations, and 300 seconds covers parsing for most long documents |
RECALL_TOP_K | 10-15 | Core business data fields of port research reports are concentrated. Excessive recall will introduce irrelevant content, and 10-15 entries cover core information |
UPLOAD_FILE_MAX_SIZE | 500 MB | Some reports include high-definition berth floor plans and route heat maps, and single-document size can reach hundreds of megabytes |
maxContext | 8000-12000 characters | The core argument section of a single port research report is lengthy, and sufficient context must be retained to support accurate question answering by the large model |
WORKFLOW_CONCURRENCY_LIMIT | 5 | Most port public data interfaces have call frequency limits. Excessive concurrency will trigger rate limit errors |
NODE_CONTEXT_SCOPE | Current node context | Retrieval of port research reports requires precise matching of specific port operation data, and global context interference is not needed |
The parameter values provided on this page are common recommendations used to set starting points for configurations. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common errors
- Symptom: Image content such as berth floor plans is missing after the workflow parses the report. Cause: The
PARSE_IMAGE_CONTENTconfiguration is not enabled, or the trigger conditions for image parsing are not set correctly. - Symptom: The large model node returns
500 Gateway forwarding error because service is disconnected. Cause: The external port data interface called in the workflow has no timeout retry mechanism configured, or the concurrency exceeds the interface limit, causing service disconnection. - Symptom: Workflow returns research report question answering results mixed with operation data from other ports. Cause:
NODE_CONTEXT_SCOPEis not set to current node context, and global context causes information interference.
How to confirm correct configuration
- Upload the longest single port research report, check whether the parsing node completes within the preset duration and image content is extracted normally.
- Initiate a single research report retrieval request, verify that the number of recall results matches the preset range and only includes relevant data for the target port.
- Submit batch tasks for more than 5 reports, check whether node execution status meets concurrency limit requirements and there are no abnormal errors.
- View workflow logs, confirm that the large model node does not have gateway forwarding errors, and the context only associates input content from the current node.
