Data Characteristics for This Category
Process validation data primarily originates from laboratory instrument output, Process Control System (PCS) records, Batch Production Records (BPR), and Quality Control (QC) reports. This data exists in both structured (e.g., database records, CSV files) and unstructured (e.g., PDF experimental reports, images, videos) formats. Update frequency is closely tied to validation batch progress, with bulk updates typically occurring after each critical validation stage. Document structures vary; for instance, experimental reports may include sections like objectives, methods, results, and conclusions, with the results section often containing charts, graphs, and extensive numerical data. Fields and units are highly specialized, such as "main component content (mg/mL)", "impurity profile (%)", "pH value", and "solubility (µg/mL)". Units must match precisely and often involve specific industry standard abbreviations.
Constraints Imposed by These Characteristics on "Deployment and Upgrade"
The diversity and specialized nature of process validation data pose specific requirements for FastGPT's deployment and upgrade. Charts, graphs, and specialized terminology in unstructured documents demand stronger multimodal understanding and domain-specific vocabulary recognition from the model, influencing model selection and embedding model update strategies. Frequent bulk data updates necessitate an efficient incremental update mechanism for the knowledge base index to avoid repetitive full re-indexing. Precise matching of specific fields and units requires strict preprocessing and validation during data ingestion to ensure data quality, potentially requiring customized extraction rules. Furthermore, due to data sensitivity, private deployment and data isolation are fundamental requirements, involving localized storage and operation of models and knowledge bases. This sets clear minimum requirements for hardware resources and network bandwidth to ensure stable operation and data security in offline environments.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Process validation reports often contain high-resolution charts and graphs, leading to large file sizes. |
maxContext | 4000 characters | Ensures capture of critical information within a single experimental report, preventing truncation. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large files and complex document structures require longer parsing times; this prevents timeouts. |
Chunk size | 800–1200 characters | Balances context completeness with recall efficiency, adapting to dense specialized terminology. |
Recall count | Top 10 entries | Guarantees relevance across multiple validation batches, improving coverage of related information. |
Similarity threshold | 0.75 | High similarity in domain-specific terminology requires a higher threshold to distinguish subtle differences. |
Three Common Mistakes
- Local private deployment model calls to external services result in connection errors, with logs showing
Connection refusedorTimeout. This is often due to network configuration or firewall settings in the local deployment environment not opening the corresponding ports. - After a knowledge base index update, image content is not recognized or updated. Query results lack image-related information. This occurs when the current version or configuration does not enable multimodal processing capabilities, or images are not correctly embedded in the document.
- Key numerical fields in query results are empty or have incorrect units. Returned results lack specific quantitative information. This is typically because specific field extraction rules were not configured during data ingestion, or unit standardization was handled improperly.
How to Confirm Correct Configuration
- Upload a process validation report containing complex charts, graphs, and specialized terminology. Use the knowledge base management interface to check document parsing status and segment previews, confirming that key information and chart descriptions are correctly extracted.
- Perform an incremental update operation on the knowledge base for a specific batch of process validation data. Observe the update time and index changes to verify that the incremental update mechanism works as expected.
- Construct queries containing specific dosages, concentrations, or batch numbers. Check if the returned results include the correct numerical values, units, and corresponding batch information to assess the accuracy of data extraction and recall.
