Data Characteristics
GMP compliance data originates from regulatory documents published by national and international drug administrations. It also includes internal quality management system documents, Standard Operating Procedures (SOPs), batch production records, inspection records, and validation reports. These documents are typically in PDF, Word, or scanned image formats. Content covers the entire process from raw material procurement, production processes, and quality control to product release, storage, and transportation.
Update cycles are relatively stable. National regulatory documents update annually or as needed. Internal SOPs revise periodically based on regulatory changes, process improvements, or audit requirements. Document structures are rigorous, often organized into chapters, clauses, and appendices. They contain extensive technical terms, abbreviations, charts, and flowcharts. Fields and units are highly standardized, such as batch numbers, expiration dates, production dates, and inspection results (e.g., mg/ml, kPa, pH values).
Constraints on Multi-Turn Conversations and Prompts
The rigorous structure and specialized terminology of GMP compliance documents require the Q&A system to precisely understand user intent during multi-turn conversations. This avoids misunderstandings due to semantic ambiguity. The periodic updates of documents necessitate regular knowledge base maintenance to ensure the timeliness and accuracy of recalled content.
Numerous charts and flowcharts challenge document parsing capabilities. Pure text RAG systems may not effectively extract key information from these visuals. The presence of standardized fields and units means the system must accurately cite or convert this data when generating responses. For example, when answering a specific inspection standard, the system should provide precise numerical ranges and units. Compliance requirements also demand traceability for conversation results, meaning the system must identify the specific clause or SOP that sourced the answer.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Segment Length) | 500–800 characters | Balances document paragraph completeness with recall efficiency, avoiding excessive truncation of critical information. |
Recall count (Recall Count) | Top 5–8 entries | GMP document clauses are highly interconnected. Increasing recall count helps cover more comprehensive context. |
Similarity threshold (Similarity Threshold) | 0.75–0.85 | Ensures precision of recalled content and reduces interference from irrelevant information. |
maxContext | 32k tokens | Accommodates complex questions and multi-turn follow-ups that may arise in GMP Q&A, providing sufficient context window. |
Rerank result count (Reranked Return Count) | Top 3 entries | Further refines recall results, improving the quality and relevance of the final answer. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses potentially long parsing times for large PDF or Word documents. |
Common Mistakes
- Conversation output lacks specific clause or source citations, preventing traceability during compliance audits. This occurs when the system is not configured or the model is not instructed to explicitly cite knowledge base sources in its answers.
- When users ask about specific batch production records or inspection reports, the system fails to provide accurate data or returns "no relevant information found." This happens when tabular data in original documents is not correctly parsed and indexed, leading to RAG recall failures.
- In multi-turn conversations, the system misinterprets user follow-up questions, causing answers to deviate from the topic. This is due to an undersized
maxContextparameter, which cannot retain enough historical conversation information, or insufficient utilization of context in the prompt.
Verification Steps
- Select typical compliance questions and conduct multi-turn conversation tests. Verify if the system accurately understands user intent and provides highly relevant initial answers.
- Randomly select 10 configured GMP documents. Ask questions about key clauses or process details. Check if the answers explicitly cite the corresponding document name, chapter, or clause number.
- Simulate user queries for specific batch production records. Check if the system can extract and display correct batch numbers, production dates, and expiration dates from structured or semi-structured data.
- Test multi-turn follow-up scenarios of varying complexity. Observe the system's performance in context understanding and information retention. Evaluate conversation coherence.
