Data Characteristics
Attenuated inactivated vaccine R&D documents originate from lab reports, clinical trial data, manufacturing process specifications, and regulatory submission materials. These documents update frequently, especially during late-stage R&D and post-market surveillance. Document structures typically include experimental protocols, data records, analysis results, and batch records. Formats often include PDF, Word, and Excel. Data fields cover virus strain information, culture conditions, purification steps, potency testing, animal challenge results, and adverse event reports. Units include viral titers (TCID50/mL), protein content (µg/mL), antibody titers (IU/mL), and animal counts. Units are highly standardized, but terminology differences exist between laboratories.
Constraints on Knowledge Base Retrieval and Recall
High update frequency requires the knowledge base to have efficient document synchronization and index update mechanisms to ensure timely retrieval results. Diverse document formats demand robust file parsing capabilities, especially for extracting structured data from complex tables and figures. The presence of specialized terminology and standardized units necessitates stronger domain knowledge embedding for semantic matching, preventing recall bias due to synonyms or abbreviations. For example, TCID50 may have multiple expressions requiring unified handling. Due to the sensitivity of experimental data and clinical results, retrieval accuracy and traceability are critical. Inaccurate recall can impact R&D decisions.

Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Segment Length) | 500–800 characters | Balances context completeness and semantic granularity, avoids diluting topics in long paragraphs. |
Recall count (Recall Count) | 8–12 entries | Ensures coverage of relevant information while managing large model processing load. |
Similarity threshold (Similarity Threshold) | 0.75–0.85 | Improves relevance of recall results, reduces low-quality recalls. |
Rerank result count (Rerank Return Count) | 5 entries | Further optimizes ranking, placing the most relevant content first. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Accommodates parsing time for large experimental reports and clinical documents. |
maxContext | 4096 tokens | Provides sufficient context for attenuated inactivated vaccine terminology and experimental details. |
Common Pitfalls
- Observation: Retrieval results contain a large amount of irrelevant production batch information. Reason: The segmentation strategy is too coarse, failing to effectively distinguish experimental data from production records.
- Observation: Experimental data for specific virus strains are not recalled. Reason: Synonym expansion or domain dictionary embedding for specialized terminology is missing, leading to semantic matching failures.
- Observation: API calls return empty results or 404 errors. Reason: Knowledge base file paths are configured incorrectly, or the indexing service is not running
