Data Characteristics
Hospital operational regulation data primarily originates from internal Hospital Information Systems (HIS), regulation management platforms, and quality management document libraries. This data updates infrequently, typically quarterly or annually, except in emergencies. Documents are mostly unstructured text, such as Word documents, PDF files, and scanned images. They contain numerous clauses, detailed rules, flowcharts, and examples. Common fields include regulation name, release date, revision history, scope, responsible department, and specific clause content. Units are primarily text descriptions, with some involving time periods (e.g., "quarterly," "annually") or quantities (e.g., "within 3 working days").
Constraints Imposed by "HTTP Interface and External Systems"
The low update frequency of hospital operational regulations means real-time data synchronization is unnecessary. Periodic fetching or manual uploads are more suitable, avoiding resource waste from frequent external interface calls. Unstructured documents are the primary data source, requiring HTTP interfaces to support uploading and parsing various file formats. Optical Character Recognition (OCR) capabilities are especially important for PDFs and scanned images. The extensive clauses and detailed rules in documents demand advanced text segmentation and embedding models to ensure complete semantic context. Fields like release date and revision history are useful for version management and retrieval filtering during external system integration. Interface design must account for their structured extraction. Text descriptions involving time periods and quantities may require Natural Language Processing (NLP) for semantic understanding and standardization when converted into queryable knowledge points.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 800–1200 characters | Ensures complete context for individual regulation clauses while balancing recall efficiency. |
Chunk size (Segment Length) | 300 characters | Balances semantic integrity and embedding model processing efficiency, preventing information dilution from overly long texts. |
Recall count (Recall Count) | Top 5 | Regulation queries require precise matching; a few high-quality recalls are better than many general results. |
Similarity threshold (Similarity Threshold) | 0.75 | Regulation queries demand high accuracy; a high threshold helps filter irrelevant results. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Allows sufficient time for parsing large PDF files or scanned images, which can be time-consuming. |
Rerank result count (Reranked Return Count) | Top 3 | Further optimizes top-ranked results to improve the precision of the final answer. |
Common Pitfalls
- Issue: The system cannot parse uploaded PDF hospital regulation documents. Reason: The HTTP interface's file parsing service lacks proper OCR configuration and cannot recognize text content in image-based PDFs.
- Issue: After an external system calls the FastGPT interface, the returned answer differs from the original regulation text or omits critical information. Reason: The text segmentation strategy is too aggressive, splitting important regulation clauses into multiple discontinuous segments, leading to a loss of semantic context.
- Issue: OneAPI fails to start, reporting
failed to get gpt-3.5-turbo token encoder. Reason: Certain external resources or configurations that OneAPI depends on failed to load correctly. This might involve network proxies, missing model encoder files, or version incompatibility.
Verification Steps
- Upload a hospital operational regulation document in PDF format containing complex charts and text. Verify that it parses successfully and generates retrievable knowledge points.
- Ask questions about key clauses within the uploaded regulation document. Confirm that the returned answers accurately cite the original text and provide the source of the relevant regulation.
- After external system integration, simulate high-concurrency calls to the HTTP interface for regulation queries. Observe if the interface response time is within an acceptable range and check for any error logs.
