What This Category of Data Looks Like
Data for railway and highway financing daily reports comes from project financing disclosure platforms of transportation authorities, bank credit ledger systems, and internal financing ledgers of project contractors. The update schedule refreshes the previous day's financing transaction data every early morning. Each daily report document uses a single transportation project as its basic organizational unit. Each record contains 9 fields: project code, project name, affiliated line/section, financing subject, cooperating bank, financing amount, arrival date, fund usage, and approval document number. Financing amount is measured in ten thousand yuan. Date fields use the YYYY-MM-DD standard format, and project codes are 12-digit unified transportation project identifiers.
What Constraints These Characteristics Impose on the "Multi-turn Dialogue and Prompt Engineering" Link
The daily update feature of railway and highway financing daily reports requires that multi-turn dialogue context be limited to valid data within the past 24 hours to avoid introducing expired financing records. The fields include standardized identifiers such as project code and financing amount. Prompts must clearly specify field extraction rules to prevent confusion between project codes and approval document numbers. Financing amount is fixed in ten thousand yuan units, and prompts must explicitly require the use of original numerical values without additional unit conversion. Daily reports are organized by project dimension, and multi-turn dialogue must associate multiple financing records for the same project. Some railway and highway projects have financing split across sections, so prompts must guide the dialogue to identify different financing entries for the same project to avoid duplication or omission.
How to Configure the Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | A single record of a railway and highway financing daily report is approximately 100 characters. Multi-turn dialogue needs to retain the last 5 pieces of project financing-related history while accommodating the full context of the current query |
systemPrompt | Please organize information by project dimension based on the provided railway and highway financing daily report data. When extracting specified fields, use original numerical values and formats, and only respond to content related to financing on the current day or a specified date | Clarify field extraction rules and data scope to avoid interference from irrelevant information, and adapt to the project-based organization format of daily reports |
relevanceThreshold | 0.75–0.85 | Fields in railway and highway financing daily reports have strong relevance. An overly high threshold will filter valid project records, while an overly low threshold will introduce irrelevant data |
topK | Top 6–8 entries | Valid project records in a single railway and highway financing daily report typically range from 5 to 7. Too many recalled entries will increase context load, while too few will miss key projects |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Railway and highway financing daily reports usually contain a large number of project entries, and parsing takes longer than general documents. Sufficient processing time must be reserved |
enableMultiRoundMemory | Enabled | Multi-turn dialogue needs to associate multiple financing records for the same project. Enabling this feature retains context association information to avoid information breaks |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Misconfigurations
- Symptom: The prompt configuration does not take effect, and the returned results do not meet expectations. Cause: The
systemPromptis not bound to the dialogue workflow, or the prompt does not clearly specify the exclusive field rules for railway and highway financing daily reports. - Symptom: The front-end dialogue page displays financing data for multiple unrelated projects at the same time. Cause: The values of
topKandrelevanceThresholdare not adjusted based on the number of daily report projects, resulting in irrelevant project financing records being included in the context. - Symptom: The dialogue returns a
504 Gateway Timeouterror. Cause:PARSE_FILE_TIMEOUT_SECONDSis not configured to a duration that meets the daily report parsing requirements, resulting in document parsing timeout.
How to Confirm the Configuration Is Correctly Set
- Upload a real railway and highway financing daily report document, initiate the first query, and check whether the returned results include the specified fields and meet the required unit standards.
- Initiate two consecutive queries related to the same project, and check whether the dialogue context retains the project association information from the previous round.
- Adjust the values of
relevanceThresholdandtopK, and verify whether the number of recalled financing records matches the project count range of the current daily report. - Simulate a single query timeout scenario, and verify whether the
PARSE_FILE_TIMEOUT_SECONDSconfiguration can prevent parsing timeout errors.
