What this category's data looks like
Data for biologics financing daily reports is sourced from public financing disclosure platforms, corporate research and development and industrial and commercial announcements, and third-party industry aggregation channels. The update frequency is once per day. Each document contains details of a single financing event, including fields such as enterprise name, financing round, financing amount, investor list, disclosure date, and core pipeline category. Financing amount is denominated in RMB ten thousand or hundred million yuan. Disclosure dates use standard date formats. No redundant nested fields are present.
What constraints these characteristics impose on vector models and indexing
The daily update rhythm requires indexes to support incremental writing and partial updates, to avoid resource consumption from full reindexing. Structured multi-field characteristics require vector models to adapt to both text descriptions and numerical information vectorization. Public channel data has minor format differences, requiring the index preprocessing link to support non-standard field formats. The length of single core text is concentrated between 200 and 500 characters, requiring matching appropriate segmentation and vectorization parameters.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
embedding_model | text-embedding-3-small or text-embedding-ada-002 | Adapts to the semantic density of biologics financing text, balances call costs and recall accuracy |
chunk_size | 800–1200 characters | Adapts to the length range of core text for single financing events, avoids segmenting and breaking core semantics |
index_type | HNSW | Adapts to daily incremental update retrieval speed requirements, balances recall accuracy and memory usage |
incremental_index_enable | true | Matches the daily update rhythm of daily reports, reduces resource consumption from full index rebuilding |
numeric_field_embedding | Financing Amount, Disclosure Date | Includes structured numerical fields in the vector index, improves accuracy of cross-field combined retrieval |
recall_top_k | Calibrated per business scenario | Adapts to the retrieval volume requirements of financing daily reports, avoids excessive redundant results |
The parameter values provided on this page are common recommended 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 on your own samples before finalizing settings.
Three common errors
- Slow index retrieval speed when calling the knowledge base interface to create an index, and the number of returned results does not meet expectations. The cause is that incremental index configuration is not enabled, and full vector matching is triggered for each retrieval.
- Some structured fields have no corresponding vector values after index generation, for example, the financing amount field is empty. The cause is that the
numeric_field_embeddingparameter is not configured, and structured numerical fields are not included in the vectorization scope. - The index model generated by calling the interface on the same day changes, which is inconsistent with the model version used previously. The cause is that the
embedding_modelfield is not specified in the interface parameters, and the platform's default dynamically updated model is used.
How to confirm the configuration is correct
- Check the
embedding_modelparameter on the index configuration page, confirm that the model version matches business requirements. - Run a vector retrieval test for a single financing event, verify that the returned results include preset structured field vectors.
- Submit newly added financing data for the day, verify that the index only updates incremental entries and does not perform full rebuilding.
- Check retrieval logs, confirm that retrieval latency meets business scenario requirements.
