Data Profile for This Category
Data sources for feed research reports include public monitoring data from the Ministry of Agriculture and Rural Affairs’ Feed Industry Office, monthly monitoring reports from the National Animal Husbandry Station, regular operating announcements from leading listed feed enterprises, and special research documents from third-party agricultural consulting institutions. Monthly monitoring data is updated in late each month. Quarterly operating reports are released within 25 working days after the quarter ends. Annual industry white papers are updated by February of the following year. Each document typically includes raw material spot prices, formula cost calculations, compliant additive usage standards, regional production capacity proportions, and similar content. Corresponding units include yuan/ton, mg/kg, and ten thousand yuan.
Constraints for Knowledge Base Retrieval and Recall
High-frequency retrieval fields such as raw material prices and formula costs have clear binding relationships between values and units. Recalled segments must fully retain the association between fields, values and units to avoid ambiguity caused by splitting. Individual research reports have lengthy content. Context semantics must be preserved during segment processing to prevent separation of fields and values. Frequently updated monthly and quarterly data require the knowledge base to support incremental synchronization to avoid content lag. Multiple units exist in some fields, so retrieval must match unit dimensions. Otherwise, recalled results cannot support accurate responses.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
segment length | 800–1200 characters | Adapts to the field association density of single segments in feed research reports, avoiding splitting the binding relationship between raw material prices and their corresponding units |
recall count | top 8–12 results | Covers multi-field information from single research reports while controlling the total context length |
similarity threshold | 0.75–0.85 | Filters low-match irrelevant research report segments, retaining content strongly related to feed raw materials and formulas |
incremental sync cycle | 1 time per day | Matches the update schedule of monthly monitoring data to synchronize latest industry information promptly |
maxContext | 6000–8000 characters | Adapts to context splicing after long document recall, avoiding exceeding the processing limit of large models |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing duration of single lengthy research reports, preventing parsing tasks from being interrupted by timeouts |
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 case-by-case analysis, and it is recommended to test against your own samples before finalizing.
Three Common Misconfigurations
- Phenomenon: Knowledge base query returns scattered content that cannot associate raw material prices with their corresponding units. Cause: Segment length is set too small, splitting the binding relationship between fields and units.
- Phenomenon: After offline deployment upgrade, knowledge base recall results are output directly without sorting. Cause: The
RESPONSE_SUMMARYconfiguration switch is not enabled, causing original recalled segments to be spliced and returned directly. - Phenomenon: Unable to upload research report files, with an upload failure prompt on the interface. Cause: The
UPLOAD_FILE_MAX_SIZEparameter is not adjusted, as single feed research report file sizes often exceed the default limit.
How to Verify Proper Configuration
- Upload a test feed research report, check the parsed segmented content to confirm that fields and units are not split.
- Initiate a retrieval request including "soybean meal price", check whether the number of recalled results and similarity matching meet preset requirements.
- View the knowledge base synchronization logs to confirm that incremental synchronization tasks execute according to the preset cycle.
- Trigger a parsing task for a single lengthy research report, confirm that no timeout errors occur during the parsing process.
