What the data for this category looks like
Biologics financial report data primarily comes from public periodic reports of listed companies, exchange filing documents, and public industry statistical materials. Updates follow a fixed schedule: quarterly, semi-annual, and annual cycles, with synchronous updates for temporary operational disclosures. Document structures include core financial statements, business segment details, R&D investment explanations, and product-related notes. Fields cover biologics operating revenue, individual product gross margin, R&D investment amount, batch issuance quantity, and more. Units include currency, percentage, and product quantity units.
What constraints these characteristics impose on vector models and indexing
Fixed-cycle updated bulk data requires indexing to support incremental synchronization, avoiding resource consumption from full reindexing. Multi-dimensional segmented fields require retaining business association relationships during indexing, preventing loss of cross-field logic after splitting. Longer document structures require matching financial report chapter boundaries during segmentation, avoiding damage to business semantics. Random updates to temporary disclosure data require configurable triggerable incremental update tasks, ensuring data timeliness.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Longer content per chapter of biologics financial reports; matching chapter boundaries during segmentation requires sufficient semantic units to avoid splitting that disrupts business logic |
chunk_overlap | 100–150 characters | Ensures semantic coherence between adjacent segments, prevents cross-chapter information breaks |
embedding_model | Doubao-embedding or general professional text models of equivalent dimension | Adapts to financial report professional terminology, supports industry text semantic understanding, aligns with actual usage needs |
index_refresh_interval | 2:00 AM daily | Matches non-peak hours for financial report disclosures, avoids occupying business resources, ensures timeliness of incremental updates |
recall_top_k | Top 8–12 results | Queries related to biologics financial reports need to cover multi-dimensional business data; appropriate recall volume ensures information completeness |
similarity_threshold | 0.72–0.78 | Filters low-relevance results while retaining weakly relevant matches for financial report segmented fields, avoids missing valid information |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common errors
- Phenomenon: When calling knowledge base retrieval, entering questions unrelated to biologics financial reports still returns partial financial report fragments. Cause:
similarity_thresholdis not configured, or the threshold is set too low, resulting in low-similarity results being recalled. - Phenomenon: Attempting to import an entire business table from the database into the knowledge base without filtering valid fields leads to index redundancy. Cause: No field filtering rules are configured, introducing non-core financial report data and increasing retrieval noise.
- Phenomenon: The knowledge base index status remains unready for an extended period, and retrieval requests cannot be initiated. Cause:
index_refresh_intervalis not set, or the scheduled task executes abnormally, causing the index construction process to interrupt.
How to confirm the configuration is correct
- Verify the vector model configuration item, confirm that a model adapted to professional text has been selected, aligning with business scenario requirements.
- Check the index refresh rules, confirm that the trigger logic matches the fixed data update cycle and temporary update scenarios.
- Initiate a typical financial report-related retrieval, verify that the relevance and coverage dimensions of the recalled results meet expectations.
- Review the index construction logs, confirm there are no abnormal error or timeout records, and the status displays as normal.
