What the Data for This Category Looks Like
Data sources for automated equipment financing daily reports include business systems of financial leasing institutions, dealer financing ledgers of equipment manufacturers, and public financing statistics from industry associations. Data updates run daily in the early morning, refreshing transaction records from the prior day. Most documents are in structured CSV or Excel formats. Each single record contains fields including unique device identifier, brand model, financing party information, financing amount (unit: RMB ten thousand yuan), financing term (unit: month), loan date, and repayment plan. Batch financing records for multiple devices are marked with a batch number.
Constraints Imposed on Knowledge Base Retrieval and Recall
Dispersed data sources lead to inconsistent field naming across different sources. For example, some records use "device model" while others use "model". Field mapping rules must be configured to resolve this. The daily update requirement means the knowledge base must support incremental indexing, to avoid the time cost of full reindexing. Structured fields include numeric values for amount and term. Numeric similarity matching logic must be configured to meet matching needs for numeric fields. Plain text matching alone cannot cover these scenarios. Single records have moderate text length. Appropriate segment length must be configured to adapt to retrieval context. Documents may include embedded device photos or contract scan copies. Image extraction parameters must be configured to ensure corresponding content is returned in retrieval results.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Structured files uploaded in a single batch for financing daily reports typically do not exceed 500 MB. This setting reserves reasonable redundancy. |
Recall count | 10-15 entries | Queries for financing daily reports usually require recent transaction records. Too many results exceed processing capacity for typical users. |
Similarity threshold | 0.78-0.82 | Balances the accuracy of structured field matching and filters irrelevant historical records. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large batches of structured files requires sufficient time to prevent timeout errors. |
enable_incremental_index | Enabled | Adapts to the daily update feature of financing daily reports, reducing indexing time. |
The parameter values provided on this page are general recommendations to serve as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: A
413 Request Entity Too Largeerror is triggered when uploading files. Cause:UPLOAD_FILE_MAX_SIZEis set too small, and does not match the actual size of financing daily report files. - Phenomenon: Embedded device photos or financing contract scan copies in documents are not returned in retrieval results. Cause: The
enable_attachment_extractconfiguration item is not enabled, and the image extraction function is not activated during parsing. - Phenomenon: The number of retrieval results is fixed at 30 when deployed locally, and cannot be adjusted. Cause: The default configuration parameter for
Recall countis not modified, and the system preset value of 30 is used.
How to Confirm Configuration is Complete
- Upload a test financing daily report file that includes device model, financing amount, and embedded images. Check that parsed fields are complete and units are unified.
- Initiate a query that includes a device model. Check that the number of returned results matches the configured
Recall count, and similarity scores fall within the set threshold range. - Initiate a query that includes image descriptions. Check that corresponding image content is returned in retrieval results.
- Wait for the next day's incremental update task to complete. Check whether new financing daily report data has been added to the knowledge base.
