Data Characteristics for This Category
Phase I clinical study Standard Operating Procedure (SOP) data originates from regulatory documents, internal pharmaceutical company policies, research protocols, and ethics committee approvals. These documents are typically in PDF, Word, or internal knowledge base page formats. Update frequency is relatively stable: regulatory documents update annually or with major policy changes, while internal SOPs revise during process optimization or regulatory updates. Document structures are rigorous, containing numerous clauses, definitions, flowcharts, and approval records. They often use numbered paragraphs, cross-references, and attachments. Fields include investigational drugs, subject screening criteria, dosing regimens, safety assessment indicators, data collection points, and adverse event handling procedures. Units strictly adhere to medical and pharmaceutical norms, such as mg/kg, mmol/L, ℃, h.
Constraints Imposed by These Characteristics on Model Integration and Configuration
Phase I clinical SOP data has a high degree of structure and specialized content, demanding extreme accuracy in model comprehension and retrieval. Extensive cross-references and nested clauses in documents require the model to handle complex contexts, preventing erroneous answers due to decontextualization. Although update frequency is not high, each update can involve core processes or critical safety indicators, necessitating an efficient incremental update mechanism. Strict unit and field specifications mean the model must precisely identify and retain this information during parsing and answer generation, preventing serious deviations from unit confusion or misinterpretation of values. Furthermore, diverse document formats require stable file parsing capabilities to ensure all text content is correctly extracted and vectorized, with particular attention to table and diagram text recognition.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Chunk Size) | 500–800 characters | Ensures each chunk contains a complete clause or logical unit, minimizing semantic loss across chunks. |
Chunk Overlap Length (Overlap Size) | 100–150 characters | Covers the relevance between adjacent clauses, handling cross-references and contextual continuity. |
Recall count (Retrieval Count) | 8–12 items | Given the complexity and multi-level information in regulatory documents, increasing retrieval quantity improves coverage. |
Similarity threshold (Similarity Threshold) | 0.78–0.85 | Balances retrieval precision and recall rate, avoiding interference from irrelevant clauses and ensuring answer relevance. |
Rerank result count (Rerank Count) | 3–5 items | Re-sorts initial retrieval results, placing the most relevant core clauses at the forefront. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses the parsing needs of large PDF or Word documents, preventing file processing failures due to timeouts. |
Common Pitfalls
- The model fails to display within the workflow dialogue, but backend logs show a response. This may occur if FastGPT's internal workflow configuration does not match the model's expected output format, leading to data transfer interruption.
- Numerical errors or unit confusion appear in answers, such as misinterpreting "milligrams" as "micrograms." This happens when unit information in the text is not adequately preserved during vectorization or when the model fails to accurately identify it during generation.
- When processing large or complex regulatory documents, some content is not indexed, leading to incomplete answers. This may result from the file parser's insufficient ability to recognize specific charts, nested tables, or text in scanned documents.
Configuration Validation
- Select a Phase I clinical SOP document with complex clauses, values, and units. Ask questions about key processes and indicators. Verify the model's answers for accuracy, especially regarding numbers and units.
- Query clauses with cross-references in the document. Confirm the model correctly understands and integrates relevant information, generating coherent and complete answers.
- Upload a new or revised policy document. Verify the model accurately responds to the new content after an incremental update.
- Simulate high-concurrency querying scenarios. Observe the model's response speed and stability to ensure performance meets expectations in actual use.
