Data Characteristics for This Category
Surgical robot registration documents draw from diverse data sources. These include design verification reports, clinical trial data, risk management files, software validation reports, biocompatibility reports, and electrical safety reports. Documents are primarily in PDF format. Some reports contain numerous charts, tables, and appendices. Data update frequency is relatively low, mainly concentrated during product development and post-market change applications. Document structures are complex, with deep nesting, and contain extensive technical jargon and acronyms. Fields and units involve medical imaging units (e.g., millimeters, pixels), mechanical units (e.g., Newtons, Pascals), time units (e.g., milliseconds, seconds), and various medical-specific dimensions.
Constraints Imposed by These Characteristics on "Reference Sourcing and Traceability"
The complex document structure and specialized terminology of surgical robot registration data require high-precision semantic understanding from the knowledge base retrieval system. This ensures accurate extraction of key information from long texts. Charts and tables within PDFs mean traditional text segmentation methods might not capture complete context. Rich text content parsing strategies require consideration. The low data update frequency means real-time requirements for the knowledge base are not high. However, strong requirements exist for historical version management and change traceability. Diverse fields and units require the system to accurately identify and retain original data measurements during referencing. This prevents reference errors due to unit confusion, especially for performance parameters and safety indicators.
Configuration Settings
| Configuration Item | Suggested Value | Rationale for This Value |
|---|---|---|
Chunk size (Chunk Length) | 500–800 characters (characters) | Balances semantic completeness of long texts with retrieval granularity. Avoids information loss from overly large or small chunks. |
Chunk Overlap Length (Chunk Overlap Length) | 50–100 characters (characters) | Ensures contextual continuity. Reduces incomplete references caused by critical information being cut at chunk boundaries. |
Recall count (Recall Count) | 10–15 entries (items) | Considering the complexity and interconnectedness of registration documents, increasing recall helps cover a more comprehensive range of potential references. |
Similarity threshold (Similarity Threshold) | 0.75–0.85 | The medical device field demands high precision. A higher threshold ensures the relevance and accuracy of references. |
Rerank result count (Reranked Return Count) | 5 entries (items) | After reranking, selects the most relevant items as final references. Reduces interference from irrelevant information. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds (seconds) | Registration documents contain numerous large PDF files. A longer parsing time is needed to avoid timeouts. |
Three Common Mistakes
- During workflow testing, subsequent questions fail to reference the knowledge base. This can happen if the knowledge base retrieval node in the workflow does not correctly pass variables. As a result, subsequent nodes cannot obtain the
datasetid. - Reference content displays a red error message. This usually indicates the reference content contains special characters or formats the system cannot recognize. Alternatively, the knowledge base chunking process might have encountered a parsing error when handling specific tables or charts.
- The knowledge base retrieval node sets a global variable
datasetid, but the node cannot reference it. This might be due to incorrect variable scope configuration or a failure to correctly identify the global variable during node parameter binding.
How to Confirm Correct Configuration
- For typical registration document questions, test the workflow. Check if each generated answer includes an accurate reference source link and can navigate to the original text.
- Randomly select multiple surgical robot design verification reports or clinical trial reports. Upload them to the knowledge base. Then, ask questions about key parameters and conclusions in the reports. Verify the accuracy of the referenced content and consistency of units.
- Simulate complex queries from declaration materials, such as cross-document references involving multiple sections or documents. Check if the system provides comprehensive reference support and if parameters like
datasetidare correctly passed. - Check log outputs. Confirm that the file parsing process has no
Parse ErrororTimeouterrors, especially for large PDF files.
