Data Characteristics
Standard answer library data in biopharmaceutical medical information (MI) response scenarios primarily consists of structured and semi-structured documents. Data sources include drug inserts, clinical guidelines, internal review literature, and official Q&A sets published by pharmaceutical companies. Data update frequency is relatively stable, typically aligning with drug lifecycles or clinical guideline revision cycles, such as large-scale updates annually or semi-annually. A few urgent pieces of information may be added quickly. Document structures are standardized, commonly in PDF, Word, or exported from internal knowledge base systems, containing clear titles, paragraphs, charts, and references. Fields include drug name, indications, dosage and administration, adverse reactions, contraindications, drug interactions, and pharmacological mechanisms. These often come with dosage units (e.g., mg, ml), time units (e.g., days, hours), and frequency descriptions.
Constraints on Workflow Orchestration from these Characteristics
The standardization and stability of standard answer library data lead to high requirements for recall accuracy and information completeness in workflow orchestration. Controllable data update frequency supports periodic tasks for preprocessing and index building, ensuring the timeliness of retrieved content. Clear document structures allow for fine-grained segmentation during data processing, such as chunking by section or paragraph, which improves RAG (Retrieval Augmented Generation) contextual relevance. The standardization of fields and units requires the workflow to accurately identify and restate this key information when extracting and generating answers, avoiding medical risks due to unit confusion or omission. Additionally, if a user's query does not directly hit the standard answer library, the workflow needs a fallback mechanism, such as guiding the user to rephrase the question or escalating to human service, to ensure the rigor of MI responses.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Chunk Length) | 500-800 characters | Ensures individual paragraphs contain sufficient context while avoiding excessive length that could lead to information redundancy or noise. |
Chunk Overlap Length (Overlap Length) | 100 characters | Maintains contextual continuity, improving the accuracy of cross-paragraph information recall. |
Recall count (Recall Count) | 3-5 entries | Balances recall efficiency with the generation model's context processing capability, reducing interference from irrelevant information. |
Similarity threshold (Similarity Threshold) | 0.75-0.85 | Filters out low-relevance results, prioritizing highly matching standard answers. |
Rerank result count (Reranked Return Count) | 3 entries | Further refines to a few most relevant items, improving the precision of the final answer. |
Temperature | 0.1-0.3 | Reduces the randomness of the model's generated answers, ensuring rigor and consistency in responses. |
Three Common Mistakes
- Symptom: Model-generated answers have low relevance to the user's question, sometimes even providing "basketball-unrelated" responses. Reason: Variables in the prompt were not passed correctly, leading to incomplete context or semantic deviation for the model.
- Symptom:
OPENAI_BASE_URL-related connection errors occur during workflow debugging. Reason: TheOPENAI_BASE_URLenvironment variable is incorrectly configured, pointing to an inaccessible address or port. - Symptom: After user input, the text content extraction step fails to obtain the required information, directly triggering a "specified response" node. Reason: The regular expression or keyword configuration for text content extraction is too strict, failing to cover the diversity of user input expressions.
How to Confirm Correct Configuration
- Test with typical Q&A pairs to verify if the workflow can accurately recall relevant passages from the standard answer library and generate expected answers.
- Simulate various user input variations (including typos and colloquial expressions) to confirm the workflow's robustness in extracting key information.
- Check workflow logs to ensure fallback mechanisms (e.g., escalating to human or prompting the user to rephrase) trigger as expected when a user's query does not hit the standard answer library.
- Evaluate the professionalism and rigor of the generated answers, ensuring that medical information, such as dosages and units, is accurate.
