What the data for this category looks like
The data for this category comes from publicly compliant industry and capital market disclosure channels, with an update frequency of synchronizing public financing information from the previous calendar day daily. Documents are presented in structured field combinations, including core fields such as full enterprise name, traditional Chinese medicine business track classification, financing amount, financing round, investor entity, financing completion date, brief project description, disclosure traceability link, etc. The financing amount is denominated in RMB, and the field hierarchy is clear with no complex nested structures.
What constraints these characteristics impose on the vector models and indexing link
The public disclosure attribute leads to format differences in some fields, for example, the unit expression of financing amounts is inconsistent. Standardized mapping must be completed before vectorization to avoid feature confusion. The daily incremental update feature requires the indexing link to support incremental synchronization, avoiding computing resource consumption caused by full reconstruction. The document structure that coexists with structured fields and unstructured project descriptions requires adapting to both structured feature encoding and natural language vector generation, and a hybrid indexing strategy must be configured. In addition, the existence of the disclosure traceability field requires retaining metadata associations in the index to ensure that recall results can trace compliant sources.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
embedding_batch_size | 8-16 | The length of a single financing document is moderate, and a small batch configuration can reduce the risk of rate limit exceeded when calling the vector model |
index_incremental_mode | Enabled | Data is updated incrementally daily, and incremental indexing reduces repeated calculations and improves synchronization efficiency |
retrieve_top_k | Top 10-15 entries | Decision-making reference for financing information requires a small number of accurate projects in the same track, avoiding too many redundant results |
embedding_rate_limit | Calibrated according to third-party platform API quotas | Avoid exceeding the call limit of the third-party vector model and prevent task interruption |
chunk_size | 300-500 characters | Adapt to the semantic length of a single financing document, and segmenting can retain complete project description information |
metadata_index_enable | Enabled | Retain metadata such as disclosure traceability to ensure that recall results can trace compliant sources |
The parameter values given on this page are conventional recommendations used to determine the starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common configuration mistakes
- Phenomenon: Vectorization tasks return a 429 status code, or logs prompt embedding rate limit exceeded. Cause: A reasonable
embedding_batch_sizeandembedding_rate_limitare not configured, causing batch requests to exceed the call limit of the third-party vector model. - Phenomenon: Knowledge base retrieval response delay is significant, and recall result generation takes a long time. Cause: Incremental indexing mode is not enabled, and each retrieval triggers full vector database matching, consuming a large amount of computing resources.
- Phenomenon: The same financing project in the dataset generates multiple independent index entries. Cause: Deduplication rules are not configured based on unique identifiers (such as full enterprise name + financing completion date), resulting in repeated data import during incremental synchronization.
How to confirm the configuration is correct
- View the vector model call logs to confirm that the configured
embedding_batch_sizeandembedding_rate_limitdo not trigger errors related to call limits. - Perform a single incremental synchronization operation to verify that only newly added financing data is included in the index, with no duplicate index entries generated for historical data.
- Perform a retrieval test to confirm that the recall results include preset metadata fields such as disclosure traceability.
- Check the execution records of indexing tasks to confirm that incremental synchronization tasks can be completed normally and switch to a ready state.
