What the Data for This Category Looks Like
Sources of renovation and decoration research reports mainly include industry trend reports released by the China Building Decoration Association, annual and quarterly operating reports of listed decoration enterprises, product specification manuals of building material manufacturers, and industry policy documents issued by housing and urban-rural development departments. Update rhythm is mostly quarterly, with policy documents updated irregularly. Document structures typically include four modules: project case analysis, material cost breakdown, construction technology standards, and policy interpretation. Some sub-reports also include regional market renovation cost data. Fields include material unit price (yuan/square meter), construction period (days), total project cost (ten thousand yuan), policy document number, and others. Common formats are PDF and Word, with a large number of embedded tables and chart data.
Constraints Imposed on Citation Source and Traceability by These Characteristics
Quantified fields in renovation and decoration research reports are numerous and have clear units. Traceability requires precise matching of fields and values, to avoid incorrect associations caused by generic text matching. Authorities vary significantly across different sources. Policy documents and reports from leading enterprises must be marked preferentially, so traceability needs to distinguish source types. Tables and charts account for a high proportion of document content. Traceability must locate specific cells or chart positions, not just match entire paragraphs of text. Additionally, some research reports have irregular update frequencies. Both document upload time and original release time must be recorded to ensure the timeliness of traceability information.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
recall_top_k | Top 8-12 results | Renovation and decoration research reports have many quantified fields, requiring sufficient recall volume to cover relevant segmented data |
similarity_threshold | 0.72-0.80 | Balance recall coverage and matching accuracy, avoid mixing in low-relevance content |
chunk_size | 800-1200 characters | Adapt to long paragraphs of tables and process descriptions in renovation and decoration research reports, reduce segmentation fragmentation |
table_parse_mode | Match by cell | Retain field associations for material unit prices and project costs, improve precise positioning capability for traceability |
enable_source_citation | Enabled | Force attachment of source information in responses, comply with compliance requirements for industry information disclosure |
rerank_top_k | Top 3-5 results | Filter redundant recall results, focus on high-relevance authoritative source content |
The parameter values provided on this page are common recommendations for starting point configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: Conversation responses do not include any source information, only displaying plain text answers. Cause: The
enable_source_citationconfiguration is not enabled, causing the system to not forcibly attach traceability identifiers. - Phenomenon: Traceability only displays the uploaded file name, and cannot locate the table paragraph or page number where specific data is located. Cause: The table cell matching parsing mode is not enabled, and recall matching is only performed based on entire paragraphs of text.
- Phenomenon: In non-tool call mode, responses do not reference knowledge base content, instead calling external search results. Cause: The
knowledge_base_priorityparameter is not adjusted, causing the system to prioritize external searches instead of matching local knowledge base content first.
How to Confirm Configuration Is Correct
- Upload a renovation and decoration industry research report in PDF format, submit a query about material unit prices or project costs, check whether the source file name, page number or paragraph position is displayed below the response.
- View the switch status of
enable_source_citationin conversation settings, confirm that the traceability display function is enabled. - Test associating multiple renovation and decoration knowledge bases, check whether the system allows configuration and normally recalls corresponding content.
- Import a research report with tables, submit a query about specific data in the table, check whether traceability locates the corresponding cell in the table.
