Data Characteristics
DTP (Direct To Patient) pharmacy regulations and SOP documents originate from drug administration regulations, pharmaceutical company product inserts, and internal pharmacy operating procedures and quality management system files. These data sources update at a relatively stable frequency. Regulatory documents typically update annually. Pharmaceutical product information may change with new drug approvals or revised inserts. Internal pharmacy SOPs adjust based on operations and external requirements, with quarterly or semi-annual update cycles. Document structures are primarily PDF, Word, or scanned images, often containing tables, diagrams, and legal terminology. Fields and units include drug names, batch numbers, expiration dates, storage conditions (e.g., temperature in Celsius ℃), operating steps, responsible personnel, and audit cycles, emphasizing precision and compliance.
Constraints for Deployment and Upgrade
The stable update cycle of DTP pharmacy regulation documents requires an efficient version management mechanism during deployment. This ensures the system identifies and indexes the latest document versions. The prevalence of PDFs and scanned images demands robust document parsing capabilities, including OCR and multi-format parsing, to extract unstructured information. Specialized terminology and legal clauses in documents make semantic understanding and answer accuracy critical. Configure appropriate retrieval and reranking strategies to handle highly specialized queries. Precise identification of specific fields like storage conditions requires high accuracy in the RAG process's information extraction phase. System upgrades must smoothly integrate new parsing models or retrieval algorithms while maintaining historical document compatibility and stable question-answering performance.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | DTP pharmacy regulation files can be large due to numerous images or scanned pages. |
Chunk size (Segment Length) | 800 characters (characters) | Regulation and SOP documents have tight logical structures; a moderate segment length helps maintain contextual integrity. |
Recall count (Retrieval Count) | 8 entries (items) | Ensures coverage of multiple relevant clauses or regulations for specialized queries, improving recall. |
Similarity threshold (Similarity Threshold) | 0.75 | Regulation Q&A demands high accuracy; a high threshold filters out low-relevance results, reducing incorrect answers. |
Rerank result count (Reranked Return Count) | 3 entries (items) | Selects the most relevant and authoritative few items from the retrieved set, improving final answer precision. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds (seconds) | OCR processing for large PDFs or scanned documents can be time-consuming; increased timeout prevents parsing interruptions. |
Common Mistakes
- After a user uploads a large PDF regulation file, the system becomes unresponsive or errors out. This occurs because
PARSE_FILE_TIMEOUT_SECONDSis set too low, causing file parsing to time out before completion. - Inaccurate answers to queries about specific parameters, such as drug storage conditions. This happens when
Similarity threshold(Similarity Threshold) is set too low, leading to the retrieval of semantically similar but non-compliant paragraphs. - Post-deployment, the system cannot answer questions about some scanned regulation content. This is due to OCR functionality not being enabled or configured, preventing the system from extracting text from images for indexing.
Verification
- Upload a batch of DTP pharmacy regulation documents containing text, tables, and scanned images. Confirm all documents parse successfully and their content is previewable in the knowledge base.
- Conduct precise question-answering tests for critical fields like drug batch numbers, expiration dates, and storage temperatures
℃. Verify the accuracy and consistency of the returned results. - Simulate user queries about specific regulatory clauses or SOP steps. Compare system answers with original document content to evaluate completeness and compliance, ensuring consistency with authoritative files.
