Data Characteristics in This Category
Site Management Organization (SMO) registration and submission document preparation involves diverse data types. These include clinical trial protocols, investigator brochures, informed consent forms, ethics approvals, case report forms (CRFs), data management plans, statistical analysis reports, pharmacovigilance reports, and various regulatory documents and guidelines. Data sources are extensive, originating from sponsors, medical institutions, and third-party laboratories. Update frequencies vary. Regulatory documents and guidelines typically update annually or with policy changes. Clinical trial documents generate and revise in real-time as trials progress. Document structures are primarily structured and semi-structured, such as PDF reports, Word document protocol revisions, and Excel subject data lists. Field and unit specificities include medical terminology, measurement units (e.g., mg/kg, ng/mL), specific coding systems (e.g., ICD-10, MedDRA), and timestamp formats (e.g., ISO 8601).
Constraints Imposed by These Characteristics on "Source and Traceability"
SMO registration and submission data characteristics impose specific constraints on source and traceability. First, multi-source heterogeneous data requires robust document parsing capabilities for knowledge base construction. Accurate extraction of charts and tables from PDFs and Word documents is crucial. Second, frequently updated clinical trial data demands incremental update capabilities for the knowledge base indexing mechanism, ensuring real-time content referencing. The authoritative nature of regulatory documents and guidelines dictates precise citation down to clauses and version numbers. Any deviation can lead to compliance risks. The presence of medical terminology and specific coding systems requires the model to accurately understand context, avoiding incorrect citations due to semantic ambiguity. Additionally, due to the rigor of submission documents, the model must provide clear citation paths in its answers, including file names, page numbers, and even paragraph numbers, to support rapid manual verification and traceability.
Configuration Settings
| Configuration Item | Recommended Value | Rationale for this Value |
|---|---|---|
chunkOverlap | 100 characters | Ensures completeness of medical terminology and short sentence context across paragraphs. |
top_k | 5 | Balances recall rate with model processing load, covering main relevant information. |
similarity_threshold | 0.75 | Filters low-relevance content, improving citation accuracy and reducing noise. |
maxContext | 3000 Tokens | Accommodates the lengthy nature of submission documents, ensuring the model gets sufficient context. |
PARSER_MODE | SEMANTIC_SPLITTER | Improves knowledge block quality for complex document structures using semantic splitting. |
output_source_info | {"file_name": true, "page_number": true} | Meets strict traceability requirements for submission documents, displaying file name and page number. |
Three Common Mistakes
- The model's answer cites outdated regulatory or guideline versions. This occurs because the knowledge base index is not updated promptly or the version management mechanism is inadequate.
- The generated answer fails to provide specific citation files and page numbers, only giving the knowledge base name. This occurs because the
output_source_infoparameter is insufficiently configured, failing to enable detailed traceability information. - The model cites clinical data semantically related to the question but not fully content-matched. This occurs because
similarity_thresholdis set too low, failing to effectively filter highly relevant knowledge blocks.
How to Confirm Proper Configuration
- Randomly select 10 typical questions. Check if the regulatory document versions cited in the model's answers are the latest and verify specific clauses in the documents.
- Verify whether the generated answers accurately provide the original document's file name and page number. Manually locate the original text to confirm content consistency.
- For questions involving medical terminology and specific coding, check if the knowledge blocks cited by the model accurately explain the meaning and application scenarios of these terms. Assess if their semantic relevance to the original text meets the expected threshold.
