Data Characteristics for this Category
siRNA nucleic acid drug registration data involves various types. Key data includes preclinical study data (in vitro, in vivo pharmacodynamics, pharmacokinetics, toxicology reports), clinical trial data (Phase I, II, III clinical study protocols, ethics approvals, informed consent forms, CRF tables, statistical analysis reports), and manufacturing process and quality control documents (CMC files, such as batch records, quality standards, stability study reports). Data sources are extensive, including internal research institution reports, CRO company submissions, and regulatory guidelines. Update frequency is relatively low, primarily at key development milestones and during regulatory policy adjustments. Document structure is complex, often unstructured text in PDF and Word formats, containing extensive specialized terminology, charts, and tabular data. Fields and units are highly specialized, such as pharmacokinetic parameters (Cmax, AUC, t1/2), toxicology indicators (LD50, NOAEL), and nucleic acid sequence information.
Constraints from these Characteristics on "Citing Sources and Traceability"
The specialized and diverse nature of siRNA nucleic acid drug data sources requires a citation and traceability mechanism that accurately identifies the origin of different document types. The unstructured nature of documents necessitates robust text parsing capabilities to extract key facts and data points from complex reports. Data update frequency is low, but updates often have a global impact. The system must ensure the timeliness of cited sources and trace back to specific versions. Extensive use of specialized fields and units demands higher semantic understanding from RAG retrieval to prevent traceability errors due to terminology ambiguity. Since large amounts of charts and tabular data are involved, pure text retrieval may be insufficient. Effective indexing and association of non-textual information are required. Finally, regulatory bodies demand strictness in submission documents, making the precision and verifiability of cited sources core constraints.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk Length | 500–800 characters | Ensures a single chunk contains a complete professional concept or experimental result description, while avoiding excessive length that leads to information redundancy. |
Recall Count | Top 8–12 | Given the professional density and relevance of siRNA data, increasing recall helps capture more relevant context. |
Similarity Threshold | 0.78–0.85 | For highly specialized texts, increase the threshold to ensure precise relevance of retrieval results. |
Rerank Return Count | Top 5 | After recall, reranking further improves the ranking of the most relevant information, focusing on core evidence. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Allows sufficient file parsing time when processing large clinical reports and CMC files. |
Knowledge Base ID Return | Enabled | Ensures each conversation explicitly returns the specific knowledge base ID for citation, facilitating traceability and verification. |
Three Common Mistakes
- Answers contain incorrect explanations of specialized terms or cited data that does not match the original text. This occurs due to overly large chunk granularity or insufficient semantic understanding, leading the model to misinterpret context during generation.
- Inability to locate a specific chart or tabular data within a report. This happens when non-textual information is not effectively extracted and indexed during file preprocessing, creating a RAG retrieval blind spot.
- Cited sources appear as "unknown" or point to irrelevant documents. This is due to outdated knowledge base indexing or overly lenient retrieval parameter settings, failing to precisely match the original source.
How to Confirm Correct Configuration
- For several key preclinical and clinical data points, verify that the model's generated content accurately cites specific sections or paragraphs of the original report.
- Randomly select complex charts or tables from submission documents and check if the model can identify and associate them with relevant text descriptions or data sources.
- Simulate queries for outdated regulations or guidelines to verify if the system can identify and prompt for updates to relevant information versions.
