What the data for this category looks like
Data for auto service financing daily reports comes from financing application ledgers of auto dealers, loan receipts from partner financial institutions, and industry financing summary documents from regional auto circulation associations. Full data for the previous day is updated every early morning. Each single document includes fields such as dealer entity information, corresponding vehicle batch, financing amount (unit: ten thousand yuan), loan date, application review status, and name of the partnered financial institution. Some documents also include associated fields for the dealer’s 30-day in-store maintenance records.
Constraints imposed by these characteristics on the citation and traceability link
The daily full update requirement means the traceability link must be configured with incremental deduplication rules to avoid repeated recall of the same financing record. Fields include financing amounts with units and clear loan date identifiers, so original units and date formats must be retained during traceability, with no unauthorized conversion. Associated maintenance record fields require cross-document association matching logic to ensure that financing applications and operational data for the same dealer can be traced. Some documents use mixed abbreviations and full names of financial institutions, so standardization mapping of institution names must be completed before traceability to avoid subject confusion in traceability results.
Configuration Recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxRecallNum | Top 8 entries | Auto service financing daily report single records include multiple associated fields. A sufficient number of recalled documents are needed to cover complete financing information and avoid missing key fields |
similarityThreshold | 0.72–0.78 | Daily report data has a high update frequency and relatively high field standardization. This interval can filter low-relevance historical redundant data while retaining associated records for the same subject |
rerankTopN | Top 4 entries | Prioritize financing records that match user queries closely, avoiding excessive non-core data interfering with traceability display |
chunkSize | 1200–1500 characters | Single financing daily report documents include multiple associated fields. Chunk length must cover complete single-record information to avoid traceability matching failures caused by field splitting |
enableSourceCite | Enabled | Clear display of source documents for financing records is required to meet users’ core needs for data traceability |
crossDocMatch | Enabled | Supports association with dealer maintenance record fields to enable cross-document traceability of data for the same subject |
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, and it is recommended to test on your own samples before finalizing.
Three Common Configuration Errors
- Symptom: Reference documents are displayed on the debug page, but no reference content appears on the official chat page. Cause: The
enableSourceCiteconfiguration item is not enabled, or the parameter is not synchronized in the deployment configuration of the official environment. - Symptom: The number of citations cannot be limited through configuration, only the similarity score threshold can be adjusted. Cause: The scope of action of
maxRecallNumandsimilarityThresholdis confused. The former controls the upper limit of the number of recalled entries, while the latter controls the similarity matching score. The corresponding parameters are not configured correctly. - Symptom: The unit of the financing amount is lost in the traceability result, only pure numbers are displayed. Cause: The
chunkSizeconfiguration is not set to cover the complete field content, resulting in the splitting of the amount field with units during chunking, making it impossible to completely match the original data.
How to Confirm Configuration Is Correct
- Upload a single auto service financing daily report test document, launch a targeted question-and-answer query, check the citation source module on the debug page, and confirm that the configuration takes effect.
- Adjust the
maxRecallNumparameter value, compare the number of recall results under different configurations, and confirm that the configuration can control the number of recalled entries. - Import associated documents containing dealer IDs and maintenance records, launch cross-subject queries, and confirm that the cross-document association matching function works properly.
- Export the original response data of the question-and-answer results, check whether complete document source fields and original unit information are included, and confirm that the chunking configuration does not lose key data.
