What this category of data looks like
Construction and decoration investment research data comes from multiple sources: decoration quota standards released by the Ministry of Housing and Urban-Rural Development, official product parameter documents from building material manufacturers, cost guidance prices released by local housing and construction commissions, project case reports from industry associations, and bid winning announcements on bidding platforms.
Data update rhythms vary: quota standards are revised every 1-2 years, building material parameters are updated when new products launch, cost guidance prices are released quarterly, and bidding announcements are updated in real time as projects open bids.
Documents include structured quota tables, semi-structured product manuals, and unstructured project cases. Fields cover material specifications, construction techniques, cost units, applicable regions, and more. Units include square meters, cubic meters, yuan, and others.
What constraints do these characteristics impose on citation source and traceability workflows
The multi-source, heterogeneous nature of construction and decoration data requires precise matching of data type and source type during traceability.
Structured quota data must be marked with specific entry codes to avoid vague citations. Real-time updated bidding and building material data must include release times to clarify timeliness.
For long-form project case documents, traceability must target specific paragraphs instead of the entire document to avoid information redundancy. Unit differences across data sources must be displayed in traceability results to prevent confusion from professional terms.
In multi-round investment research follow-up scenarios, historical cited document contexts must be associated to ensure consistent traceability logic.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
recall_top_k | Top 8-12 entries | Construction and decoration has numerous specialized techniques and material parameters. Sufficient entries must be recalled to cover professional investment research scenarios |
similarity_threshold | 0.72-0.78 | When matching specialized technical terms, filter irrelevant general decoration content to improve recall accuracy |
parse_chunk_size | 800-1000 characters | Adapt to the paragraph length of decoration quotas and product manuals. Ensure single-paragraph information is complete and traceable |
source_display_mode | Display full path + release time | Construction and decoration data has large differences in timeliness. Clearly mark source release time and document location |
context_window_size | First 3 rounds of conversation context | Adapt to multi-round investment research follow-up logic. Retain context association of historical citations |
parse_file_timeout_seconds | 120 seconds | Avoid parsing timeout interruptions when processing large bidding PDFs and quota manuals |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Returning only citations without reply content: The phenomenon is that API calls return empty text but include source links. The cause is that the citation template for
llm_response_promptis not configured, or the template only retains the source placeholder without adding reply generation logic. - Citation function fails for password-free shared links: The phenomenon is that in version 4.9.6, the original text can still be viewed after disabling the citation viewing permission for password-free shared links. The cause is that the associated configuration of
share_link_permissionandsource_view_permissionwas not updated synchronously, or there is a permission check logic bug in the version. - Multi-round conversation context is not included in traceability: The phenomenon is that subsequent follow-up questions do not associate with historically cited documents. The cause is that the
enable_multi_round_recallparameter is not enabled, or the context window size is set too small to cover historical interactions.
How to Verify Correct Configuration
- Upload a construction and decoration building material product manual, trigger a professional question and answer, check if the sources attached to the reply include the full document path, release time and specific paragraph location.
- Test a password-free shared link, verify that after disabling the citation viewing permission, users cannot directly jump to the original text details page.
- Launch two consecutive investment research follow-up questions, check if the traceability information in the second reply is associated with the document content cited in the first round.
- Upload a large construction and decoration quota PDF file, verify that the parsing process does not have timeout errors, and the segmented recalled content fully covers technical parameter details.
