Multi-Turn Conversations and Prompts for Laboratory Service

Data Characteristics for This Category

Laboratory service regulation data primarily comes from various quality management system documents, standard operating procedures (SOPs), instrument operation manuals, safety guidelines, and personnel training records. These documents are typically in PDF, Word, or scanned image formats, with a small portion as structured database records. The update frequency is relatively stable, usually following annual reviews or triggers from significant changes. Document structures are highly standardized, including chapters, clauses, and appendices, and often reference other regulatory documents. Fields involve operational steps, equipment models, reagent batch numbers, operator signatures, and calibration dates. Units include volume (mL), mass (g), temperature (℃), and time (min), with very high precision requirements.

Constraints These Characteristics Impose on Multi-Turn Conversations and Prompts

The standardized structure and cross-referencing of regulatory documents require multi-turn conversation systems to accurately identify context and track referenced clauses. For example, when a user asks about an operational step, the system must understand any specific instrument calibration regulations it might depend on. The heavy reliance on images and scanned documents presents challenges for document parsing, requiring accurate text extraction to avoid missing critical information. The strictness of fields and units means prompt design must precisely guide the model to extract these key values, preventing vague or incorrect quantitative information in model responses. A lower update frequency reduces the pressure for immediate data synchronization but requires high-quality processing of large volumes of historical documents during knowledge base construction and the provision of version management mechanisms.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`Chunk size` (Segment Length)	`800–1200 characters`	Regulatory documents have close contextual relationships; increasing segment length retains more contextual information.
`Recall count` (Recall Count)	`Top 5 entries`	Ensures enough relevant regulatory clauses are recalled to cover the potential scope of user queries.
`Similarity threshold` (Similarity Threshold)	`0.75`	Balances recall rate and precision, avoiding the retrieval of irrelevant regulatory content.
`Rerank result count` (Rerank Return Count)	`3 entries`	After reranking, focuses on the three most relevant pieces of information to improve answer quality.
`maxContext`	`3000 Tokens`	Regulatory Q&A requires a longer conversation history to understand multi-turn context and references.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Accommodates complex parsing tasks for large regulatory documents or scanned images, allowing sufficient processing time.

Three Common Mistakes

Conversation response times are excessively long, or even time out, with logs showing significant model invocation duration. This is due to improper document parsing parameter settings, such as PARSE_FILE_TIMEOUT_SECONDS being too short, leading to large documents not being fully processed.
When users inquire about regulatory details in multi-turn conversations, the model fails to correctly associate historical conversation content, providing disjointed answers. This is due to insufficient maxContext parameter configuration, preventing the model from effectively retaining and utilizing the complete conversation context.
When copying generated Markdown formatted content, line breaks are lost or formatting is corrupted. This is because the model does not strictly adhere to Markdown specifications during content generation, or the frontend rendering component has insufficient compatibility with specific Markdown syntax.

How to Confirm Proper Configuration

Select multiple regulatory questions with complex references and conduct multi-turn conversation tests to observe if the model can accurately track and answer relevant clauses.
Upload regulatory documents in different formats (PDF, Word, scanned images) and sizes, checking if the document parsing status is normal and ensuring no timeouts or parsing failures are recorded.
By simulating actual operational scenarios, ask questions involving specific fields and units to verify the accuracy of quantitative information in the model's answers, such as instrument calibration dates or reagent concentration values.
