What the data for this category looks like
Data sources for minor metals financing daily reports include publicly disclosed industry data from the China Nonferrous Metals Industry Association Minor Metals Branch, corporate financing announcements from local commodity exchanges, and compiled information from third-party industry news platforms. Updates run daily, covering publicly available financing information from the previous trading day. Document structure combines structured tables and brief industry commentary. Individual document word counts vary widely. It is recommended to calculate based on your own samples or conduct testing before finalizing configurations. Fields include report date, minor metal subcategory, financing amount (unit: RMB ten thousand yuan), financing subject, fund provider type, financing term, financing purpose, and a summary of the day’s market trend for the corresponding category.
What constraints these characteristics impose on the knowledge base retrieval and recall link
Multi-source and heterogeneous data sources require the retrieval system to support cross-data source field unified mapping, to avoid repeated recall of the same financing information. Daily update frequency requires that the knowledge base incremental synchronization task runs daily, and recall prioritizes the most recently published documents. The structured field system supports field-level precise retrieval, but differences in field naming across data sources require pre-configured unified mapping rules. The large number of subcategories requires adding a minor metal category filter condition during recall, to avoid mixing financing information from unrelated categories into results. The structured format of individual documents requires first matching core fields during retrieval, then using full-text content for supplementary recall.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall count | top 10 | Minor metals financing daily reports focus on a single category per entry. Excessive recall leads to redundant results. Core information is concentrated in the latest 3 to 5 entries, and 10 entries cover complete daily and nearly two days of financing updates |
similarity threshold | 0.75-0.85 | Minor metal category names have high recognizability. A threshold that is too low will recall financing information from unrelated categories, while a threshold that is too high may miss financing records for the same category but different subjects |
incremental synchronization cycle | daily at 02:00 | Financing daily reports typically complete daily data aggregation in the early morning. Daily synchronization ensures the timeliness of knowledge base data |
field recall weight | financing amount field weight is 2, financing subject field weight is 1.5 | When users search for minor metals financing daily reports, core needs are specific category financing amount and subject information. Increasing the weight of these fields improves retrieval accuracy |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Individual minor metals financing daily reports include structured tables and industry commentary, with moderate parsing duration. 300 seconds covers parsing requirements for most documents |
maxContext | 800-1200 characters | Core information of a single financing daily report is concentrated within 800 characters. Excessively long context introduces irrelevant content, affecting the relevance of retrieval results |
The parameter values provided on this page are all conventional recommendations used as 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 conduct testing on your own samples before finalizing.
Three common errors
- Phenomenon: A 401 status code is returned when calling the API to synchronize the knowledge base collection, prompting authentication failure. Cause: The correct
Authorizationfield is not included in the API request header, or the configured API key has insufficient permissions to access the target knowledge base collection. - Phenomenon: A general error pop-up appears on the interface after clicking to add a folder or create a new directory in the knowledge base. Cause: The knowledge base storage provider has not been configured in advance, or the configuration parameters for the storage provider are filled incorrectly, resulting in failed initialization verification during directory creation.
- Phenomenon: Financing information from other nonferrous metal categories is mixed into recall results when searching for minor metals financing daily reports. Cause: The filter rule for the
minor metal categoryfield is not configured, or the field recall weight is set too low, causing the system to fail to accurately distinguish financing data from different categories.
How to confirm the configuration is complete
- Perform a manual incremental synchronization once, check if the synchronization log shows "synchronization completed" with no error records, and verify that the number of documents after synchronization matches the daily update volume of the data source.
- Enter a search term that includes a specific minor metal category and financing amount, check if the recall results prioritize matching core fields in sorting, and filter out information from unrelated categories.
- View the knowledge base configuration page, confirm that the values of parameters such as
incremental synchronization cycleandsimilarity thresholdmatch the preset configuration. - Call the retrieval API, check if the returned results include correct fields such as
minor metal categoryandfinancing amount, and that the field format matches the preset mapping rules.
