Data Characteristics in This Category
CMC (Chemistry, Manufacturing, and Control) research data originates from experimental records, batch production records, quality control reports, and stability study reports during drug development. This data updates infrequently, typically with advancements in drug development phases or changes in production batches. Document structures primarily consist of structured tabular data and unstructured text reports, such as process flow diagrams, analytical method validation reports, and raw material quality inspection reports. Fields include substance names, batch numbers, production dates, expiration dates, test indicators, result values, units (e.g., mg/mL, ppm, ng/mL, %, pH), and deviation descriptions. The data volume is large and contains extensive specialized terminology, including chemical formulas, CAS numbers, and professional instrumental analysis data.
Constraints Imposed by These Characteristics on Multiturn Conversations and Prompts
CMC research data is highly specialized. Multiturn conversations must handle a large volume of specialized terminology and complex data structures, demanding high semantic understanding from the model. The low data update frequency allows for a relatively relaxed knowledge base maintenance cycle, but each update requires ensuring data consistency and completeness. Diverse document structures necessitate building the knowledge base to accommodate both structured data extraction and unstructured text comprehension. For example, a user might ask about the impurity content of a specific drug batch, requiring the model to precisely retrieve numerical values from structured reports. Another query might involve potential adverse reactions from a certain manufacturing process, requiring inference from unstructured text. Accurate unit identification is crucial to prevent erroneous judgments caused by unit confusion. In multiturn conversations, users may progressively refine their questions, requiring the model to understand context and perform multi-step reasoning.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 6 | Maintains conversational coherence while balancing performance and cost. |
Chunk size (Segment Length) | 500–800 characters (characters) | Accommodates long descriptions and tabular content in CMC reports, improving recall accuracy. |
Recall count (Recall Count) | Top 8 entries (top 8) | Covers a wider range of potentially relevant knowledge points, addressing multi-step reasoning needs. |
Similarity threshold (Similarity Threshold) | 0.75 | Balances recall and precision, preventing interference from irrelevant information. |
Temperature | 0.3 | Reduces the randomness of model-generated content, ensuring rigor and accuracy. |
Prompt | Calibrated by actual testing | Must include instructions for unit conversion, molecular formula recognition, batch filtering, etc., to ensure precise responses. |
Three Common Pitfalls
- Conversation freezes or unresponsiveness: This can occur due to excessive knowledge base loading or prolonged model inference time, leading to interface timeouts.
- LaTeX format display anomalies: Inconsistencies between the LaTeX renderer supported in model output or debugging previews and the renderer used in the published application can cause formulas to display incorrectly.
- Unexpected intermediate process information in AI conversation results: Improper prompt or workflow configuration can cause intermediate AI conversation node results from the workflow to be erroneously included in the final output.
How to Confirm Proper Configuration
- Conduct multiturn conversation tests for typical CMC scenarios (e.g., specific batch impurity analysis, impact of process changes) and check the accuracy of responses.
- Verify the model's ability to recognize and convert different units (e.g.,
ng/mLtoppm) and correctly handle chemical formulas. - After knowledge base updates, check if the model can accurately answer questions about new data and cross-reference key values with original documents.
- Simulate user queries containing specialized terminology and abbreviations to confirm the model's correct understanding and provision of relevant information.
