What the data for this category looks like
Specialized equipment data comes from four sources: original equipment manufacturer (OEM) technical specifications, internal financial institution usage guidelines, regulatory compliance filing documents, and equipment operation and maintenance update logs. Update frequency adjusts based on business and regulatory needs. OEM firmware updates trigger on demand. Compliance documents update alongside regulatory policy changes. Internal usage guidelines adjust with business process updates. Organize documents by equipment model. Each document includes technical parameters with clear units, applicable business scenarios, compliance operation procedures, and troubleshooting steps. Fields include equipment ID, rated load, applicable financial product types, maintenance cycles, and additional relevant details.
What constraints do these characteristics impose on knowledge base retrieval and recall?
Distinguish between compliance and technical content in multi-source documents to avoid recalling outdated compliance information. Long technical parameters and clear unit fields demand precise parameter association during retrieval, without breaking context. Trigger full index updates regularly to ensure recalled content aligns with the latest regulatory and business requirements, given the non-fixed update rhythm. Match multiple equipment model documents precisely by model to prevent generic recall that produces irrelevant results.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Specialized equipment documents often contain long technical parameters. Too short a chunk length breaks the association between parameters and units. Too long a chunk length exceeds the model context window. |
| Number of Recalled Entries | Top 6–8 entries | Specialized equipment parameters are highly segmented and there are many equipment models. Too few entries miss precisely matched model documents. Too many entries increase the model's processing burden. |
| Similarity Threshold | 0.75–0.85 | Precise matching of parameters, units, and model information is required. A threshold that is too low recalls irrelevant equipment documents. A threshold that is too high misses compliance content with similar parameters. |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Specialized equipment documents may contain multiple parameter charts. The default timeout duration is insufficient to complete full parsing. |
| Number of Reranked Returned Entries | Top 3–4 entries | Prioritize returning the most matching equipment models and core parameters for user queries, avoiding redundant information that interferes with model understanding. |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Analyze specific issues on a case-by-case basis, and conduct testing on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: After configuring a model with internet access, retrieval results only come from the knowledge base, with no external supplementary information. Cause: Mixed recall configuration is not enabled, and only knowledge base retrieval mode is activated.
- Phenomenon: After uploading equipment technical documents, retrieval results cannot match precise units or model parameters. Cause: Structured field parsing function is not enabled, so parameters and units are treated as plain text.
- Phenomenon: When parsing large equipment documents, the task times out and fails, returning status code 504. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the default timeout duration is insufficient to parse documents with multiple charts.
How to Confirm the Configuration Is Correct
- Upload an equipment document with clear model and parameters. Initiate a query that includes that model and parameters. Verify the recalled results include the corresponding document fragments.
- Enter the knowledge base management interface. Review parsing task logs to confirm no timeout or parsing failure records exist.
- Enter the application configuration page. Check that the similarity threshold and number of recalled entries match the preset configuration.
- Enable the application debug mode. Review the intermediate retrieval and recall results to confirm matched fields and units meet expectations.
