What data for this category looks like
Data for electronic component financing daily reports comes from public industrial supply chain financing disclosure platforms, official financing announcement disclosures from component manufacturers, and daily summary files from third-party industry data service providers. Data updates release the previous natural day's financing records every early morning. Most documents use structured CSV or JSON formats. Each entry corresponds to one manufacturer's one-day financing details, and includes these fields: component category code, full manufacturer name, financing amount (unit: ten thousand RMB / ten thousand USD), financing completion date, fund provider, financing purpose, and associated industrial park.
Constraints on Knowledge Base Retrieval and Recall
First, the data includes financing amount fields with multiple units. Retrieval must match both the component category code and the amount unit, otherwise RMB and USD financing records will be mixed. Second, the daily high-frequency update requirement means the knowledge base must support incremental synchronization. Otherwise, recall results will have too high a proportion of old data, failing to meet real-time needs. Third, the core retrieval term is the component category code. Field-level indexing must be used instead of full-text indexing. Full-text indexing will match irrelevant manufacturer names or purpose fields, reducing retrieval accuracy. Fourth, each single data entry has clear fields but a large total count. The number of fields returned in recall must be limited. This avoids exceeding the large model's context window limit, and reduces interference from invalid information on retrieval results.
Configuration Settings
| Config Item | Recommended Value | Rationale |
|---|---|---|
Recall Count | Top 10-15 entries | Each entry in the electronic component financing daily report is brief. Precise retrieval terms can quickly locate target records. Too many results will increase business processing burden |
Similarity Threshold | 0.75-0.85 | The core retrieval term is the component category code, which is a precise matching field. A threshold that is too low will introduce a large number of irrelevant financing records |
Chunk Length | 800-1200 characters | Each single financing daily report entry is approximately 200 characters. Chunking and merging adjacent data from the same manufacturer can improve context coherence and adapt to large model understanding logic |
Incremental Update Trigger Cycle | 2:00 daily | The data source updates the previous day's data every early morning. Scheduled incremental synchronization ensures the real-time nature of knowledge base data |
UPLOAD_FILE_MAX_SIZE | 500 MB | Monthly aggregated electronic component financing data files usually do not exceed this size, preventing upload failures due to oversized files |
Reranked Return Count | Top 5 entries | The core business requirement is to obtain the latest accurate financing details of the day. A small number of results is sufficient for the usage scenario |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing the settings.
Three Common Mistakes
- Issue: Specifying two knowledge base IDs when calling the API returns empty results. Cause: Cross-knowledge base retrieval permission configuration is not enabled, and only single knowledge base calls are allowed.
- Issue: Garbled characters appear in fields after uploading a CSV file exported from WPS. Cause: The CSV file uses GBK encoding instead of UTF-8, and the corresponding encoding format was not specified during document parsing.
- Issue: Non-electronic component category financing records are included in retrieval results. Cause: The field-level retrieval switch is not enabled, and full-text retrieval is used instead, which matches irrelevant manufacturer names or purpose fields.
How to Verify Proper Configuration
- Enter preset electronic component model and financing date keywords, verify that returned result fields include matching category codes and amount units.
- View the knowledge base synchronization log to confirm that the daily early morning incremental update task executed successfully, with no parsing failures or timeout records.
- Call the API interface, pass the configured knowledge base ID parameter, and check that returned results include the file collection ID field.
- Adjust retrieval configuration items, compare recall results across different parameter sets, and confirm that matching accuracy meets business requirements.
