Data Characteristics for Product Usage
Biomedical product usage data originates from product manuals, operating instructions, FAQs, online help documentation, and internal training materials. This data typically exists as unstructured text, PDFs, HTML pages, or structured database records. Data update frequency varies from monthly to several times a year, depending on product iterations, regulatory changes, or user feedback. Manuals usually include standard sections like indications, dosage, precautions, and contraindications. Operating instructions focus on specific steps, diagrams, and troubleshooting. Common fields and units include drug dosage units (mg, μg, mL), usage frequency (once daily, hourly), device parameters (temperature ℃, pressure kPa), and specific operation durations (minutes, hours).
Constraints Imposed by These Characteristics on Workflow Orchestration
The unstructured nature of product usage data requires robust document parsing capabilities during data ingestion. This ensures accurate extraction of key information from various file formats. The uncertain update frequency necessitates support for incremental updates and version management within the workflow. This guarantees the knowledge base always reflects the latest product information and avoids providing outdated guidance. The hierarchical structure of manuals, such as chapters and sub-sections, demands sophisticated retrieval strategies within the workflow. This enables multi-granularity information matching.
Furthermore, the biomedical field requires extreme accuracy and rigor. Any information regarding dosage or safety must be precise. This is critical during response generation and safety validation within the workflow, requiring the avoidance of vague or ambiguous expressions. The presence of specific fields and units also requires the workflow to correctly identify and process these specialized terms, such as distinguishing between mg and g, when understanding and generating responses.
Configuration Guidelines
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
Chunk Size | 500-800 characters | Ensures individual chunks contain sufficient context while avoiding information overload, facilitating model comprehension. |
Recall Count | Top 5-8 | Balances retrieval efficiency and coverage, covering multiple potentially relevant knowledge points. |
Similarity Threshold | 0.7-0.8 | Ensures strong relevance of recalled content, reduces interference from irrelevant information, and guarantees response accuracy. |
Reranked Return Count | Top 3 | Focuses on the most relevant pieces of information, reduces the model's processing burden, and improves response speed. |
Max Token Count | 2048-4096 | Accommodates longer product descriptions and operating procedures, supporting answers to complex questions. |
Safety Validation Keywords | Calibrated by actual measurement | Sets strict trigger words for sensitive information like contraindications and adverse reactions to mitigate risks. |
Common Pitfalls
- Customer service responses display "Key is error" or similar technical error messages. This occurs when the workflow fails to correctly process user input special characters or when API key configuration is incorrect.
- User feedback questions receive inaccurate answers or overly generic responses. This happens when knowledge base chunking granularity is too large or retrieval strategies are inappropriate, failing to precisely match specific product usage instructions.
- Workflow execution time is excessively long, and user waiting time exceeds expectations. This results from too many chained calls to external services or unreasonable model inference parameter settings, leading to low processing efficiency.
Validation Steps
- Submit simulated product usage questions. Verify if customer service responses accurately cite specific steps and parameters from product manuals or operating instructions.
- Test questions containing specialized terms and units. Check if responses correctly identify and use these terms and units.
- Simulate various question formats, such as interrogative sentences, declarative sentences, and multi-turn conversations. Validate that the workflow provides consistent and professional answers in different contexts.
- Review workflow logs. Confirm that preset safety validation mechanisms are triggered when handling sensitive questions (e.g., dosage, adverse reactions).
