Data Characteristics for This Category
Attenuated inactivated vaccine registration documents involve extensive and diverse data sources. Core data includes: strain origin and passage records, media components, inactivation process parameters (e.g., formaldehyde concentration, reaction time, temperature), adjuvant type and dosage, purification methods, formulation, stability study data, batch production records, preclinical animal study data, and clinical trial protocols and reports. This data exists in both structured (e.g., numerical values in batch test reports, clinical trial databases) and unstructured forms (e.g., research reports, SOP documents, meeting minutes). During the R&D phase, data updates frequently. During the registration phase, data tends to stabilize but may undergo localized revisions due to regulatory requirements or supplementary studies. Document formats vary, including PDF, Word, Excel, and image files. Some data may reside in LIMS or EDC systems. Fields and units are highly specialized, for example, "Tissue Culture Infectious Dose 50 (TCID50)," "Antigen Content (μg/mL)," "Residual DNA (ng/dose)," and must strictly adhere to pharmacopoeia standards and ICH guidelines.
Constraints Imposed by These Characteristics on Workflow Orchestration
The data characteristics of attenuated inactivated vaccine registration documents impose specific requirements on workflow orchestration. Data source heterogeneity dictates that workflows must support multi-source data ingestion. This includes API integration for LIMS system data or file parsing modules for PDF/Word documents. Varying update frequencies necessitate a version control mechanism. This ensures processing of the latest or specified data version and enables historical change traceability. Diverse document formats require robust file parsing capabilities to accurately extract key information from different formats. The strictness of specialized fields and units demands data standardization and validation after extraction. This can involve unit conversion and numerical range checks using predefined regular expressions or dictionaries. Furthermore, due to the rigorous nature of submission documents, every data processing step must be traceable and support manual review to meet regulatory compliance requirements.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Allows sufficient time for OCR and text extraction from large PDF reports and scanned documents. |
maxContext | 8192 token | Covers the full context of a single key document (e.g., clinical study summary report), reducing information loss. |
Chunk size | 800 characters | Balances semantic completeness and segment recall efficiency, preventing key information dilution in long paragraphs. |
Recall count | Top 5 entries | Reduces unnecessary computation while maintaining relevance, focusing on core information. |
Similarity threshold | 0.75 | Ensures recalled document segments are highly relevant to the query, filtering out low-quality fuzzy matches. |
API_CALL_RETRY_TIMES | 3 times | Addresses occasional network fluctuations or transient failures in external LIMS or EDC systems. |
Three Common Mistakes
- Workflow external API calls fail due to authentication issues or empty data. This typically occurs when authentication parameters like
tokenare incorrect or expired, or the external interface returns an unexpected structure. - Uploaded Excel file content cannot be correctly read or parsed by the workflow. This may be due to file encoding or format issues, or the workflow lacks a configured parser to recognize Excel cell data.
- The workflow gets stuck at the first dialogue stage after interacting with a specific node and fails to proceed to subsequent nodes. This often results from improperly configured conditional judgment nodes that fail to correctly capture the output of the previous node or match predefined trigger conditions.
How to Verify Configuration
- Upload attenuated inactivated vaccine documents in various formats (PDF, Word, Excel). Verify the workflow successfully parses and extracts key fields. Check the completeness and accuracy of the extracted results.
- Simulate queries containing specific strain information and inactivation process parameters. Confirm the workflow recalls relevant research reports and batch production records from the knowledge base. Check the number of recalled items against expectations in the logs.
- Execute workflows that include external API calls. Verify normal data interaction with LIMS or EDC systems by checking API return status codes and data content. Ensure data format meets subsequent processing requirements.
- Design complex queries with conditional judgments, for example, querying reports for a specific clinical trial phase. Verify the workflow's logical branches execute as expected and produce correct results.
