What This Type of Data Looks Like
Residential development financing daily report data primarily comes from public disclosure platforms of housing construction authorities, credit granting announcements from commercial banks, and interim disclosure documents of listed real estate enterprises. Updates are issued daily. Each daily report contains one or more financing project records. The document structure is fixed, with six core fields: project name, full name of the development entity, financing amount, financing method, disclosure date, and disclosure channel. Amount units are ten thousand yuan or hundred million yuan. Date format follows YYYY-MM-DD. Some disclosure files include original announcement links for subsequent traceability.
Constraints Imposed by Data Characteristics on Citation Sources and Traceability Workflows
The daily update requirement means the traceability workflow must precisely match disclosure dates, to avoid confusing financing information for the same project across different dates. The multi-source disclosure characteristic requires the recall step to cover relevant data from multiple channels including housing construction authorities, commercial banks, and real estate enterprises, preventing information omission. Differences in field specifications require the traceability workflow to strictly distinguish similar fields such as financing amount and credit limit, avoiding deviations in search results. The complete single-item data structure requires segmentation rules to use a single daily report as the unit, ensuring traceability information is not split and lost.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_count | 8-12 entries | Residential development financing daily reports have small per-item data volume. Multi-channel disclosure information for the same project financing usually does not exceed 10 entries. This value range covers all valid sources |
similarity_threshold | 0.72-0.80 | Project names and development entities in financing daily reports often have abbreviation differences. A threshold that is too high will miss valid data matched by abbreviations. A threshold that is too low will mix in financing information from unrelated industries |
source_data_field_mapping | Map according to project name → project name, financing amount → financing amount, disclosure date → publish time, disclosure link → source link | Match the field expressions commonly used in user searches, to ensure core information can be accurately displayed during citation traceability |
document_segmentation_rule | Segment using a single daily report as the unit | Single daily reports have complete structures. Segmenting by single daily reports preserves complete disclosure information and traceability links, avoiding loss of key content after segmentation |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapt to batch import of daily updated residential development financing daily report files, avoid timeout during single batch processing, and is compatible with batch import logic for versions 4.8.20 and above |
traceability_link_auto_extraction | Enabled | Daily reports often include original disclosure links. Automatic extraction directly displays jumpable traceable sources in citation results |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. Testing on local samples is recommended before finalizing settings.
Three Common Misconfigurations
- Phenomenon: When searching for residential development financing daily reports, the returned results only show 1 citation record. Cause: The
recall_countconfiguration value is set too low, failing to cover multi-channel disclosed financing information for the same project. - Phenomenon: After importing daily report files, knowledge base search results do not display disclosure source links. Cause: The
traceability_link_auto_extractionconfiguration is not enabled, or the disclosure link mapping rule is not configured duringsource_data_field_mapping. - Phenomenon: When batch importing the same day's daily report files, the interface displays a file parsing timeout error. Forced ignoring allows the application to run normally. Cause: The
PARSE_FILE_TIMEOUT_SECONDSconfiguration value is set too short, failing to reserve sufficient time for processing batch imported daily report files.
How to Verify Successful Configuration
- Import a single standard-format residential development financing daily report file, view the parsed field list in the knowledge base, and confirm it matches the preset
source_data_field_mappingrules. - Initiate a search request containing "XX project development loan", view the citation list in the returned results, and confirm it includes at least 2 matching records from different channels.
- Click the link of any citation source, confirm it jumps to the original disclosure page, verifying that the traceability link configuration is active.
- Batch import 3 days of residential development financing daily report files, check that the parsing progress completes within the
PARSE_FILE_TIMEOUT_SECONDStime range, with no timeout prompts.
