Data Characteristics
Surgical robot registration documents draw data from diverse sources. These include clinical trial reports, design documents, risk management reports, software validation reports, biocompatibility reports, and electrical safety reports. Data is typically stored in formats like PDF, DOCX, and XLSX. These documents contain extensive technical details, specification requirements, and regulatory clauses. Data update frequency depends on R&D progress and regulatory changes; updates are concentrated during new version iterations or regulatory revisions. Document structures are complex, often with numerous cross-references and attachments. Fields include Unique Device Identification (UDI), product model, software version, clinical indications, intended use, and contraindications. Units cover engineering and medical dimensions such as millimeters, grams, volts, amperes, hertz, and pascals.
Constraints on Multi-Turn Conversations and Prompts
The complexity of surgical robot documentation requires multi-turn conversation systems to have strong context understanding and precise knowledge retrieval. Extensive technical details and cross-references demand deep semantic parsing to accurately identify user intent and provide relevant information. Multi-format documents and complex structures make traditional keyword matching ineffective, necessitating advanced RAG strategies for unstructured data. Specialized terminology and industry acronyms challenge prompt robustness, requiring the model to handle term variations or synonyms. Regulatory rigor demands extremely high accuracy in responses; any deviation could lead to registration risks. This imposes strict requirements on prompt guidance and model output reliability. The uncertain update frequency means the knowledge base must support efficient incremental updates and version management, ensuring conversation content is always based on the latest registration standards.
Configuration Settings
| Configuration Item | Recommended Value | Rationale for Recommendation |
|---|---|---|
maxContext | 10 | Ensures multi-turn conversations can cover the derivation process of complex issues while balancing retrieval efficiency. |
Chunk size (Segment Length) | 800-1200 characters (characters) | Balances textual semantic integrity with retrieval granularity, adapting to long sentences and paragraphs in technical documents. |
Recall count (Retrieval Count) | 8-12 entries (items) | Increases coverage of relevant information to address scattered but highly related knowledge points in the documentation. |
Similarity threshold (Similarity Threshold) | 0.78-0.85 | Guarantees high relevance of retrieval results, reducing interference from irrelevant information, especially for regulatory clauses. |
Rerank result count (Reranked Return Count) | 5 entries (items) | Focuses on the most core and accurate information, improving the precision of the final answer and reducing model hallucinations. |
temperature | 0.1-0.3 | Controls the determinism of model output, ensuring the rigor of answers and compliance with regulations. |
Common Pitfalls
- Conversations include content unrelated to registration documents. This occurs when prompts do not explicitly limit the scope of answers, causing the model to diverge.
- Long response times or errors after user queries. This typically results from file parsing timeouts or incomplete knowledge base indexing, especially for large PDF documents.
- The model cites outdated regulatory versions in its answers. This happens when the knowledge base is not updated promptly, or the latest version is not specified during the query.
Verification of Configuration
- Conduct multi-turn conversation tests for key questions in typical registration processes. Check the accuracy and completeness of answers.
- Simulate user input containing specialized terminology and acronyms. Verify if the model correctly understands and provides relevant results.
- Review retrieved content in conversation details. Determine if retrieved items are highly relevant to user intent. Validate the similarity threshold.
- Randomly select documents from the knowledge base. Verify segmenting and indexing meet expectations. Ensure no parsing errors or content omissions.
