What the data for this category looks like
The data for specialized equipment intelligent due diligence reports in the financial sector primarily comes from equipment factory qualification certificates, operation and maintenance logs, quarterly quality inspection reports, and industry regulatory filing documents. Data follows two update cycles: Factory documents are updated once upon equipment delivery. Operation and maintenance logs are synchronized monthly. Batch quality inspection reports are updated with each production batch. Each individual document has a fixed structure, including fields such as equipment model, unique serial number, rated power, cumulative operating hours, maintenance cycle, and compliance certificate number. Units use standard industrial measurement units including kW, hours, and pieces. No nested complex sub-documents are present.
What constraints these characteristics impose on the vector models and indexing workflow
Structured fields such as equipment model and serial number are mixed with unstructured content such as operation logs and compliance descriptions. This requires distinguishing field types during vector encoding to avoid diluting structured metadata with semantic vectors. Data update cycles vary widely across sources. An incremental index update mechanism must be configured to avoid resource consumption from full index rebuilding. Individual document lengths vary greatly: some are short operation alerts with tens of characters, while others are thousands of characters long compliance reports. Dynamic segmentation parameters must be supported to adapt to text blocks of different lengths. Most institutions use standard measurement units. Index metadata must retain unit fields to support subsequent association and verification.
How to set the configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Adapts to the average length of specialized equipment documents, covering the main content blocks of operation logs and compliance reports |
chunk_overlap | 100–150 characters | Retains contextual association between segments, preventing key cross-segment information such as equipment operating hours and maintenance cycles from being broken |
top_k | Top 6–8 results | The associated information density of specialized equipment due diligence reports is high. Too many recall results will introduce irrelevant content, while too few will fail to cover key compliance items |
score_threshold | 0.72–0.78 | Filters low-relevance equipment model matching results, retaining content that meets the semantic matching threshold for due diligence questions |
structured_metadata_enable | Enabled | Retains structured fields such as equipment serial number and rated power for subsequent precise metadata filtering |
index_refresh_mode | Incremental synchronization | Adapts to the differentiated update cycles of multi-source data, reducing resource usage for index construction |
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 mistakes
- Symptom: Index status shows "Not Ready", and knowledge base search cannot be triggered. Cause: The trigger condition for incremental synchronization is not configured, or newly added bulk equipment documents have not completed vector encoding.
- Symptom: Search returns equipment model content unrelated to the query, and the number of recalled results exceeds expectations. Cause: The
score_thresholdis set too low, or structured metadata filtering is not enabled, resulting in low-relevance content being recalled. - Symptom: After importing the full equipment database table, search results include content from fields unrelated to due diligence. Cause: The
structured_field_includeparameter is not configured to specify fields to be included in the index, resulting in irrelevant metadata being encoded into vectors.
How to confirm the configuration is correct
- Upload a single equipment compliance report, check the segment preview results, and confirm that the segment length and overlap parameters match the configured expectations.
- Input a test question containing an equipment model, check the number of recall results and similarity scores, and confirm they fall within the configured parameter range.
- Add a new operation log document, check the index update log, and confirm that incremental synchronization was triggered and full index rebuilding was not initiated.
- View the metadata panel, confirm that structured field retention is enabled, and the specified fields are displayed normally.
