What the data for this category looks like
Data for fertilizer and pesticide declaration and case review comes primarily from the Ministry of Agriculture and Rural Affairs’ pesticide and fertilizer registration and filing database, official application materials submitted by enterprises, third-party quality inspection reports, and field trial archives. Data updates align with the annual approval cycle for newly registered products, and are also updated quarterly alongside industry standard revisions. Most documents are fixed-format Word or PDF files, containing standard fields such as registration certificate number, active ingredient content, manufacturer name, and approval document number. Units mostly use agricultural and chemical-specific measurement methods including g/L, kg/ha, and mass percentage.
Constraints These Characteristics Impose on Knowledge Base Retrieval and Recall
Fixed standard fields and specialized measurement units require retrieval to match both field names and unit information. This prevents recall results where active ingredient content does not correspond to its listed unit. Most structured documents are in Word or PDF format. After parsing, section titles must be retained as contextual association information. Without this, it is impossible to accurately locate the registration clauses for a specific product. The mixed annual and quarterly update rhythm requires configuring incremental sync tasks. This ensures the latest versions of the filing database and enterprise application materials are included in the knowledge base. A large number of similar declaration materials for similar products requires filtering redundant results during recall. This avoids duplicate content interfering with review judgments.
How to Configure the Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Matches the precision requirements for fertilizer and pesticide registration fields. Prevents irrelevant material recalls if set too low, and misses valid compliant content if set too high |
limit | Top 8 entries | Single-batch recall results cover core review points for most declaration materials, while controlling context length |
searchMode | vector + keyword | Balances semantic matching and field keyword matching, adapting to retrieval needs for fixed fields and structured documents |
usingReRank | Enabled | Re-sorts recall results by relevance, resolving sorting confusion caused by high similarity between declaration materials of similar products |
datasetSearchUsingExtensionQuery | Enabled | Automatically expands synonymous terms related to review. For example, associates "active ingredient" with "active component", adapting to differences in industry-specific terminology |
collectionIds | Specify pesticide/fertilizer registration library collection ID | Limits retrieval scope to only declaration and case data related to fertilizers and pesticides, avoiding interference from cross-category content |
Three Common Mistakes
- Phenomenon: Retrieval results include reference links to knowledge base files, which cannot be directly used by review personnel. Cause: The metadata output switch for retrieval results is not turned off. The default setting includes file source links.
- Phenomenon: After uploading doc/docx files, retrieval results do not include section titles, making it impossible to locate specific approval clauses. Cause: The section title extraction configuration during document parsing is not enabled. Only plain text content is extracted.
- Phenomenon: AI responses exceed the scope of the knowledge base, introducing unfiled product information. Cause: Strict knowledge base content restriction rules are not configured, allowing the model to call external knowledge to generate responses.
How to Confirm the Configuration Is Correct
- Upload a standard fertilizer and pesticide registration application document. After performing a retrieval, check whether the returned results include the corresponding section title information.
- Initiate a retrieval request. Verify that the returned results do not include file source links, confirming that the reference switch has been turned off.
- Input an industry term outside the knowledge base. Check whether the AI cannot generate a corresponding response, confirming that the content restriction rules are in effect.
- Submit search terms with different units, such as "active ingredient content" and "g/L". Confirm that retrieval results only match registration data with the corresponding unit.
