Data Characteristics in this Category
Quality documents in the neurodegenerative disease field, such as SOPs, batch production records, and analytical method validation reports for drug R&D and manufacturing (e.g., for Alzheimer's or Parkinson's disease), primarily source data from internal Quality Management Systems (QMS), Laboratory Information Management Systems (LIMS), and external regulatory guidelines (e.g., FDA, EMA). Document update frequency depends on R&D progress, regulatory revisions, and production process optimization. Reviews are typically quarterly or annually, but critical changes may trigger immediate updates. Document structures are rigorous, often using sections, appendices, and revision histories. Fields include batch numbers, test results, analytical methods, instrument calibration information, operators, and date/time stamps. Units strictly follow pharmacopoeia or industry standards, such as mg/mL for concentration, min for time, and ℃ for temperature.
Constraints on "Citing Sources and Traceability" Imposed by These Characteristics
The rigorous nature of neurodegenerative disease quality documents requires source citations to be precise down to specific versions, page numbers, or sections to ensure accurate and compliant traceability. The periodic and immediate nature of document updates demands real-time synchronization capabilities for the knowledge base, preventing citations of outdated or superseded versions. Diverse document structures and fields require the knowledge base to effectively parse various formats like PDF and Word, and identify key information such as batch numbers or experimental data. Specific unit systems and specialized terminology require the system to have strong semantic understanding, accurately matching queries with document content, and avoiding citation errors due to imprecise technical vocabulary, especially in multilingual environments.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
Chunk size (Chunk Size) | 500–800 characters | Ensures each knowledge chunk contains sufficient context while avoiding information redundancy, facilitating RAG model understanding. |
Recall count (Recall Count) | 8–12 items | Increases coverage while maintaining recall relevance, addressing potentially scattered key information within documents. |
Similarity threshold (Similarity Threshold) | 0.75–0.85 | Balances precision and recall, reducing irrelevant content citations while not missing potentially critical information. |
Rerank result count (Reranked Return Count) | 4–6 items | Selects the most relevant citation snippets, reducing the processing burden on the subsequent LLM and improving final answer quality. |
maxContext | 32000 tokens | Accommodates complex queries and multi-document citation scenarios, ensuring the LLM has enough context to generate complete answers. |
AUTO_UPDATE_INTERVAL_HOURS | 24 hours | Balances document update frequency with system resource consumption, ensuring relatively fresh knowledge base content. |
Three Common Mistakes
- Symptom: AI answers cite batch numbers or experimental data that do not match the actual document. Reason: Document parsing failed to accurately identify and extract specific fields, or the knowledge base did not timely synchronize the latest revised document versions.
- Symptom: When asked about the stability data of a compound, the AI fails to cite relevant SOPs or validation reports. Reason: The
Similarity threshold(Similarity Threshold) was set too high, causing the recall stage to filter out potentially relevant but semantically slightly less similar document snippets. - Symptom: When calling an API workflow, the knowledge base search results are empty after passing the
knowledgeBaseIdvariable. Reason: The [Knowledge Base Search] node in the workflow configuration did not correctly reference the externally passed variable, or the variable types did not match.
How to Confirm Proper Configuration
- Select recently revised quality documents. Ask questions about the revised content and verify if the sources cited in the AI's answer are the latest versions, and if the cited page numbers or sections are precise.
- Use queries containing specialized terms like specific batch numbers or test methods. Check if the AI's answer can accurately cite document snippets containing this information and confirm that the extracted field values match the original text.
- Simulate complex problems that might occur in production or R&D processes, such as issues involving multiple SOPs working together. Observe if the AI can provide multi-source citations and evaluate the logical coherence of these citations.
- Regularly check knowledge base synchronization logs to confirm that document update tasks are executing as expected, and look for any parsing failure or version conflict warning messages.
