What This Category's Data Looks Like
Shipping port financing daily report data is primarily sourced from national major port operation platforms, public shipping exchange data, and financial institution shipping financing ledgers. Full data for the previous day is updated each early morning. Each document includes fields such as daily port container throughput, trunk line shipping capacity changes, individual shipping financing credit lines, actual loan amounts, and ship rental unit prices. Unified field units apply: throughput is measured in ten thousand tons, financing-related amounts in ten thousand RMB, and rental costs in yuan per natural day.
Constraints Imposed on Multi-turn Dialogue and Prompt Engineering
The daily full data update requirement means conversation context must support date-based data filtering. This prevents the return of expired historical information. The structure with multiple fields and clear units requires prompts to enforce field matching rules. This avoids unit confusion or field misalignment. The need to correlate data across operation and financing sources means multi-turn dialogue must support first retrieving port operation data, then linking to query corresponding financing ledgers. This prevents the direct return of uncorrelated scattered data.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Single shipping port financing daily report attachments typically do not exceed 300 MB, with reasonable buffer space reserved |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Long documents require sufficient time to split and parse fields, avoiding mid-process interruptions |
maxContext | 8000–10000 characters | Retain recent port operation and financing data context to support cross-data-source linked queries |
Recall Count | Top 6 entries | The core fields of daily reports are limited; precise recall avoids interference from redundant data |
Similarity Threshold | 0.75–0.85 | Distinguish similar port names and financing projects, reducing false matching probability |
S3_PRESIGNED_URL_EXPIRE | 300 seconds | Adapt to time consumption requirements of large file chunked uploads, preventing pre-signed URLs from expiring early |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Scenario: After upgrading to version 4.14.3, an error
fail to create post presigned urlappears when uploading financing daily report attachments. The cause is incorrect cross-origin rule configuration for S3 storage or an overly short pre-signed URL expiration time. - Scenario: The financing data returned by multi-turn dialogue has mixed units. The cause is that the prompt fails to enforce field unit matching rules, causing the model to mix values with different units.
- Scenario: Recalled port data does not match the day's financing ledger. The cause is an overly large recall count, introducing non-current historical data entries.
How to Verify Proper Configuration
- Upload a standard-format shipping port financing daily report attachment, check that the specified core fields can be successfully parsed and extracted.
- Initiate a multi-turn dialogue: first query the day's port throughput data, then link to query the corresponding financing amount, verifying that the context-linked logic works.
- Check the system upload logs, confirm that pre-signed URL generation has no errors, and that template import and regular file uploads complete normally.
- Adjust the similarity threshold, test recall results for similar port names, verifying that matching rules perform as expected.
