What Data for This Category Looks Like
Financial report data for the construction and decoration industry comes primarily from public annual and quarterly reports of listed companies, plus monthly operating data released by industry associations. Public financial report documents include consolidated balance sheets, income statements, cash flow statements, sections on main business composition, details of major project contracts, and more. Core fields include current period revenue, single project contract amount, operating cost, gross margin, ending accounts receivable balance, all denominated in RMB ten thousand yuan. Monthly industry data covers dimensions such as regional decoration activity and building material price indexes. Update cadence: annual reports are disclosed once per year, quarterly reports once per quarter, and industry data is updated monthly.
How These Characteristics Impose Constraints on Multi-turn Dialogue and Prompt Engineering
The multi-period data structure of construction and decoration financial reports requires multi-turn dialogue to support users switching between annual, quarterly, or monthly dimensions for follow-up questions, avoiding repeated input of period parameters. Decentralized storage of single project contract details requires prompts to explicitly specify filtering conditions such as project name and report period to accurately retrieve corresponding content. The unified RMB ten thousand yuan unit requires prompts to default to this unit to avoid mismatched amount units. The long document structure requires the multi-turn dialogue context window to adapt to the text length of a single financial report, preventing key information from being truncated. Additionally, differences in update cadences across data sources require clear marking of the data’s disclosure period in responses to ensure answer timeliness.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | The text length of a single quarterly financial report in the construction and decoration industry typically ranges from 5000 to 10000 characters, reserving sufficient space to retain multi-turn dialogue history |
UPLOAD_FILE_MAX_SIZE | 200 MB | Annual reports in the construction and decoration industry may include multi-page PDFs and attached tables, with individual file sizes exceeding 150 MB |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Multi-page text splitting and field extraction for long documents require extended processing time to avoid parsing timeout interruptions |
Recall count | Top 6 entries | Core information from construction and decoration financial reports is scattered across multiple sections such as revenue, costs, and project details; recalling 6 entries can cover key modules |
Similarity threshold | 0.75–0.85 | Financial report field descriptions are standardized. An overly high threshold will miss relevant content, while an overly low threshold will introduce irrelevant industry-wide data |
Chunk size | 1000–1500 characters | The content length of individual sections in construction and decoration financial reports is moderate, and segmentation can improve retrieval accuracy |
The parameter values provided on this page are general recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Issue: A 503 error appears when uploading a construction and decoration financial report PDF, but uploading knowledge base files proceeds normally. Cause:
UPLOAD_FILE_MAX_SIZEis not configured to adapt to large files, or the temporary storage quota for dialogue sessions is insufficient, triggering backend rate limits during file upload. - Issue: When using a strict question-answering template, image address links from the knowledge base are retrieved, and the prompt indicates no answer was found. Cause: The strict question-answering template only matches text content, and the parsing switch for image content is not enabled, so embedded financial report data in images cannot be extracted.
- Issue: A prompt reading "No permission to operate this dialogue record" displays when operating dialogue history. Cause: Dialogue permission range parameters are not configured, or the correct permission group is not bound, resulting in interception of cross-session access.
How to Confirm Proper Configuration
- Upload a PDF file of standard size for construction and decoration industry financial reports, verify that parsing and dialogue processes function normally, and confirm that file upload configurations adapt to the target file size.
- Input a query that includes a specified project name and report period, check that retrieved content matches the filtering conditions, and confirm that recall-related configurations adapt to the field matching logic of financial reports.
- Send two dialogue requests with a very short interval between them, verify that they can be processed in parallel, and confirm that concurrent session parameters are correctly configured.
- Upload a financial report attachment containing embedded images, check that image content is effectively extracted and used for question answering, and confirm that image parsing-related configurations are enabled.
