What the data for this category looks like
Consumer building materials financing daily report data sources include public monitoring data from the National Building Materials Circulation Association, project financing information filed by local housing and urban-rural development departments, and transaction disclosure data from supply chain financial service platforms. Data is updated daily, released before 18:00 on the current day for the previous day’s financing information. Documents mostly use Excel or CSV formats, split into separate worksheets by region and building material subcategory. Each sheet contains six fields: financing subject name, financing amount, financing term, financing purpose, release date, and data source institution. Financing amount is measured in ten thousand yuan, and financing term is measured in months or calendar days.
What constraints these characteristics impose on the "citation sources and traceability" link
Multi-source data requires the traceability system to fully retain the source institution identifier for each data entry, to avoid mixing financing information from different channels. Daily incremental update rhythm requires the traceability module to support filtering and recalling content by release date, to prevent mixing historical redundant data. Tabular document structure requires parsing to split entries line by line, to avoid traceability confusion caused by cross-row references. Clear fields and units require full retention of field names and units during traceability, to prevent information loss that affects verification accuracy. Diversity of financing subjects requires the traceability module to match unique subject identifiers, to ensure accurate distinction between financing data of different subjects.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size | 800–1200 characters | A single financing entry for consumer building materials financing daily reports is approximately 200-300 characters. This segment length covers complete entries and avoids cross-entry splitting, preserving the contextual integrity of a single financing entry |
Recall count | Top 6–8 entries | Daily financing entries usually number in the tens. This value balances information density and output conciseness, avoiding redundancy or omission of core data |
Similarity threshold | 0.72–0.78 | Distinguishes similar names of different dealers and project subjects in the same category, avoiding recalling financing data from unrelated building material categories |
Enable Source Display | Configure visibility per entry | Consumer building materials financing data requires clear traceability to the publishing institution and date. Core entries must display sources, while auxiliary information can be hidden as needed |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Monthly summary consumer building materials financing daily report files have large volume. This duration prevents parsing timeout interruptions |
Rerank result count | Top 3–4 entries | Focuses on core financing entries, aligns with the concise reading habit of industry daily reports, avoiding output of excessive irrelevant information |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: Only the original user question is returned when called, with no corresponding financing daily report content. The interface displays "No valid knowledge base content recalled". Cause: The
Recall countsetting is too low, and theSimilarity thresholdsetting is too high, making it impossible to match relevant entries from consumer building materials financing daily reports. - Phenomenon: The output financing data does not include traceability fields such as publishing institution and publishing date. Cause: The
Enable Source Displayconfiguration is not separately set for core entries of consumer building materials financing daily reports. The global visibility is mistakenly set to hidden. - Phenomenon: When parsing financing daily report files, some entries do not generate question-and-answer pairs, and the original text is inserted directly. Cause: The
Chunk sizesetting is too short, splitting a single financing entry into multiple segments. This causes the parsing module to fail to recognize complete financing information units and generate corresponding question-and-answer pairs.
How to confirm the configuration is correct
- Upload a single consumer building materials financing daily report file, check the parsed segmented content, confirm that single financing entries are not split across segments.
- Initiate a test query, enter a financing question related to a region or building material category, check that the number of recalled entries matches the
Recall countsetting. - Check the output results, confirm that core financing entries all include traceability fields such as publishing institution and publishing date.
- Test the configuration to hide some sources, confirm that only specified auxiliary information does not display sources, while core financing entries normally display traceability information.
