What This Category's Data Looks Like
Data sources for agrochemical product research reports include public reports from industry associations, chemical industry research reports from securities firms, columns from professional agricultural materials media, and annual operating announcements from leading agrochemical enterprises. Update frequency adjusts based on core events. Regular industry supply and demand reports are updated monthly. Immediate supplementary reports are released when pesticide policy changes or large raw material price fluctuations occur. Most documents are in PDF format, with four fixed sections: core indicator panels, market supply and demand analysis, competitor dynamics, and policy interpretation. Professional fields include active ingredient content (unit: g/L or mass percentage), production capacity (unit: 10,000 tons/year), sales volume (unit: tons), publishing organization and publishing date, and other specialized information.
Constraints for Knowledge Base Retrieval and Reranking
The characteristics of this dataset create constraints for the knowledge base retrieval and reranking workflow. Dispersed multi-source data requires the knowledge base to support multi-channel data access, preventing incomplete information coverage from single data sources. Content with varying update frequencies needs differentiated incremental synchronization rules, to align sync frequency with policy-based immediate reports and regular monthly reports. Long document structures and dense professional terms require retaining sufficient contextual association during retrieval, avoiding semantic coherence breaks caused by paragraph splitting. Diverse fields and units require preprocessing normalization, to ensure consistent retrieval and matching of equivalent data from different sources.
Configuration Settings
| Configuration Key | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Single agrochemical research report PDFs are typically 10-50 pages, with file sizes usually under 500 MB |
maxContext | 8000–12000 characters | Agrochemical research reports contain professional terms and long sentence structures, requiring sufficient context to maintain semantic coherence |
Recall Count | Top 8–12 results | Professional data in agrochemical research reports is scattered across paragraphs, requiring sufficient recall volume to cover relevant information |
Similarity Threshold | 0.75–0.85 | High matching requirements for professional terms, to avoid recalling irrelevant general chemical documents |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Text extraction and structure recognition for long PDF documents require extended processing time |
Reranked Return Count | Top 5–8 results | Filter the most relevant research report content after reranking, to avoid information overload that reduces retrieval efficiency |
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 individual analysis. It is recommended to test with your own samples before finalizing settings.
Three Common Configuration Mistakes
- A 401 Unauthorized error is returned when calling the knowledge base API. The cause is failure to disable the default configuration that automatically adds a Bearer prefix to API requests, resulting in damaged secret key format and failed authentication.
- A large number of non-agrochemical general chemical research reports are included in retrieval results. The cause is an overly low similarity threshold, without precise filtering for professional term matching.
- Text truncation occurs after parsing long PDF research reports. The cause is failure to adjust the
PARSE_FILE_TIMEOUT_SECONDSparameter, with parsing timeout leading to incomplete text extraction.
How to Verify Proper Configuration
- Upload a single agrochemical research report file, and confirm the parsing task status is completed with no parsing failure log entries.
- Submit a retrieval request containing agrochemical professional terms, and verify that recall results include relevant content fragments from reports of the target category.
- Call the knowledge base API interface, manually configure the Authorization field in the request header, and confirm no extra Bearer prefix is automatically added.
- View the knowledge base update records, and confirm research reports are synchronized at the set frequency.
