What This Category of Data Looks Like
Data related to yield rates in the engineering consulting field comes from project financial calculation drafts, cost consulting databases, and cost indicator libraries released by industry authorities. Updates are triggered in stages as the project progresses, and are synchronized when project costs are adjusted or capital plans change. Single-project data is stored as structured tables, including fields such as project ID, project name, calculation cycle, fixed investment amount, variable cost amount, annual cash flow sequence, and return calculation value. Amounts are denominated in RMB yuan. Cycles are measured in natural months or natural years. Calculation values are dimensionless numbers.
What Constraints Do These Characteristics Impose on Multi-turn Dialogue and Prompting
Decentralized data sources mean full valid information cannot be obtained in a single step. Multi-turn dialogue must gradually guide users to supplement corresponding document fragments. Update rhythms are not fixed, so dialogue must support users to supplement latest cost and cash flow data and adjust calculation parameters at any time. Structured document formats require prompts to clearly specify field formats, to avoid messy user input. Complete cash flow sequences rely on multi-round supplements, so dialogue must identify missing fields step by step and proactively ask questions. At the same time, multi-turn dialogue must retain historical context to ensure user-supplied parameters are linked to previously submitted content, and avoid repeating questions about already provided information.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Financial calculation documents for engineering consulting projects usually contain multiple segments of cash flow and cost data. A sufficient context window retains complete multi-turn dialogue and historical calculation parameters |
recallTopK | Top 6–8 entries | Engineering consulting data has many fields. Too many recalled entries introduce irrelevant information, while too few fail to cover complete calculation logic |
similarityThreshold | 0.72–0.78 | Distinguishes exclusive calculation data for engineering consulting projects from general industry documents, and avoids confusing parameters of different projects |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Financial calculation documents for engineering consulting usually contain multi-page tables, so parsing takes a long time and the timeout period must be extended |
UPLOAD_FILE_MAX_SIZE | 50 MB | Drafts for engineering consulting projects usually contain multiple drawings and table attachments, so larger file uploads are allowed |
systemPrompt | Sort the engineering consulting yield rate data provided by users in the format of project ID, calculation cycle, cost category, and cash flow sequence. Clearly ask for any missing fields | Matches the structured characteristics of engineering consulting data, and guides users to provide content in standardized formats |
The parameter values provided on this page are conventional recommendations used as starting points for configuration. 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 Mistakes
- A 413 Request Entity Too Large error is returned when calling the dialogue interface to upload engineering consulting drafts. Cause: The
UPLOAD_FILE_MAX_SIZEconfiguration is not adjusted to match the size of project drafts, and the default parameter limits file upload capacity. - Repeatedly asking for already provided fixed or variable cost data during multi-turn dialogue. Cause: The
maxContextparameter is not configured correctly, and the context window is too small, resulting in lost historical dialogue content and failure to recognize information already submitted by the user. - Calculation results are mixed with general question-and-answer logic because the prompt does not distinguish roles. Cause: The
systemPromptis not used to clearly define rules for the engineering consulting scenario, and human input is not bound to project-specific parameters, confusing general and scenario-based question-and-answer logic.
How to Confirm Proper Configuration
- Upload a financial draft for an engineering consulting project, check that file parsing completes within the time set by
PARSE_FILE_TIMEOUT_SECONDS, and there are no parsing failure errors. - Initiate a multi-turn dialogue: first provide fixed cost data, then supplement variable cost data, and confirm that the system retains historically entered information and does not repeatedly ask about already submitted content.
- Adjust the
similarityThresholdparameter, test recall results under different thresholds, and confirm that only relevant data for the current engineering consulting project is matched. - Call the dialogue interface to upload a test file, confirm that the returned response status code is
200 OK, and there are no errors related to upload restrictions.
