What This Category of Data Looks Like
Beneficial owner KYC data mainly comes from enterprise industrial and commercial registration annual reports, equity penetration due diligence documents, and regulatory submission materials. Data update rhythm triggers when the subject’s equity changes, and is synchronized during fixed annual report cycles. Each document mostly consists of structured tables paired with supplementary explanatory text. Core fields include unified social credit code, natural person name/institution name, shareholding ratio, actual contributed capital, and position held. Shareholding ratio is measured in percentage. Actual contributed capital is measured in ten thousand yuan.
Constraints Imposed on Knowledge Base Retrieval and Recall
The coexistence of structured fields and supplementary text in beneficial owner data requires retrieval to cover both exact field matching and semantic association recall. Relying solely on a single retrieval method may cause information omission. The update rhythm of data has no fixed high-frequency trigger. The knowledge base must support incremental synchronous updates. Full refresh will cause delays and waste resources. Equity-related fields have strong associative properties. The recall link must retain the hierarchical relationship between subjects. Splitting data will lose equity link information, preventing restoration of the complete beneficial owner structure. Long supplementary text requires retaining the binding relationship between fields and their corresponding descriptions during segmented retrieval. Context breaks may lead to equity logic errors, which affects subsequent verification accuracy.
Configuration Settings
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
Recall Count | Top 10-15 entries | Beneficial owner data contains multi-level associated subjects. Sufficient associated documents are needed to restore the complete equity link |
Similarity Threshold | 0.75-0.85 | High precision is required for equity subject matching. Low-match irrelevant subject information must be filtered out |
Segment Length | 800-1200 characters | The binding relationship between equity hierarchy and corresponding descriptions must be retained to avoid context breaks |
Reranker Model | Calibrated based on actual testing | The semantic characteristics of beneficial owner data differ from general scenarios. Reranking logic needs adaptive adjustment |
Field Matching Weight | Structured field weight 0.6, semantic weight 0.4 | Prioritize accurate matching effects for structured fields such as equity subjects and shareholding ratios |
Incremental Update Trigger Rule | Triggered by subject equity changes | Match the update rhythm of beneficial owner data. Avoid invalid full refresh occupying resources |
The parameter values provided 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. It is recommended to test on your own samples before finalizing the configuration.
Three Common Mistakes
- Phenomenon: Reranker model fails to start, and the log returns the
model load failederror code. Reason: Beneficial owner data contains a large number of financial professional terms. General reranker models are not adapted to the semantic characteristics of this scenario, leading to loading or inference failure. - Phenomenon: The number of knowledge base retrieval results is insufficient to cover the complete equity link. Reason: The
Recall Countparameter value is not adjusted. The default number is too small to cover documents of multi-level associated subjects. - Phenomenon: The retrieved output content is not strictly limited to knowledge base matching content, and irrelevant generated text is mixed in. Reason: The mandatory reference binding configuration for retrieval results is not enabled, and the reply is not restricted to only use the recalled knowledge base document content.
How to Confirm Proper Configuration
- Upload a single beneficial owner document. Check if the parsed fields in the knowledge base completely match the core information of the original document. Confirm that the segment configuration does not cause field association breaks.
- Enter a query containing specific shareholding ratios or subject names. Verify the number and sorting logic of recalled results. Validate the configuration effects of the similarity threshold and field weights.
- Modify the equity information of a test subject. Trigger the incremental update rule, then check if the knowledge base automatically synchronizes and updates the document of this subject. Confirm that the update trigger logic is normal.
- Enable the reranker model and execute a query. Check if the rearranged results are sorted according to the closeness of equity association. Validate the adaptation effect of the model.
