Reference and Traceability for Ophthalmology Regulations

Data Characteristics

Ophthalmology regulations and SOP documents are typically issued by healthcare institutions, industry associations, or regulatory bodies. Update frequencies vary. Regulatory documents may be revised annually or in response to specific events. Operational procedures update with technological advancements or clinical practice optimizations, usually every 1–3 years. Documents are primarily in PDF or Word formats, containing numerous charts, flowcharts, and specialized terminology. Key fields include document number, publication date, revision version, scope, operating steps, risk warnings, and cited standards. Units include clinical measurements (e.g., mmHg, diopters), drug dosages (milligrams, micrograms), and time units (seconds, minutes).

Constraints on "Reference and Traceability"

The update frequency of ophthalmology regulatory documents requires regular knowledge base updates and version management to ensure reference accuracy. Extensive specialized terminology and charts challenge text parsing and semantic understanding, potentially affecting the precise location of cited fragments. Document numbers and revision versions are crucial for traceability; the system must accurately identify and link this metadata. The presence of clinical measurement units necessitates a citation mechanism that distinguishes values from units to prevent citation errors due due to formatting differences. Furthermore, common flowcharts and complex tables in documents require stronger structured information extraction capabilities for the system to point to specific operational steps or conditions during citation.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`maxContext`	`800–1200 characters`	Captures complete regulatory clauses or operational steps while avoiding irrelevant information.
`similarity_threshold`	`0.78`	Balances recall and precision, reducing the risk of incorrect citations. Adjust based on empirical testing.
`rerank_top_n`	`3`	Focuses on the most relevant regulatory fragments, reduces model processing load, and improves response speed.
`quote_type`	`text_block`	Regulatory documents often consist of continuous text; this type is suitable for extracting complete paragraphs as citations.
`metadata_extraction_rules`	`{"Document Number": "reg_no", "publication date": "pub_date"}`	Accurately extracts document metadata for traceability and version management.
`embedding_model`	`text-embedding-ada-002`	Suitable for semantic understanding in specialized domains, effectively handles medical terminology.

Common Configuration Mistakes

Replies do not show specific page numbers or paragraphs of cited documents, preventing users from quickly verifying the original text. This occurs when page number or paragraph identifier fields are not correctly configured in metadata_extraction_rules, or if this information is not preserved during document parsing.
Cited content is irrelevant to the answer, resulting in "quote type error" or semantically incoherent cited fragments. This may be due to a similarity_threshold set too low, recalling irrelevant document blocks, or maxContext being too small, truncating meaningful context.
Replies cite outdated versions of regulations, inconsistent with the latest publications. This happens when the knowledge base is not updated promptly, or the document version management mechanism is not effective, leading to retrieval of older document versions.

Verification Steps

Select multiple typical questions with clear citation sources. Observe if the replies include citation information precise to the paragraph or page number.
Randomly select cited fragments from replies. Manually verify their location and semantics in the original document, ensuring consistency with the context.
Test questions about the latest revised regulations. Check if the system accurately cites the most recent version and if older versions are no longer cited.
Test questions containing specialized terminology or complex flowcharts. Verify that the cited content accurately points to relevant chart descriptions or step-by-step instructions.
