Monoclonal Antibody Quality Document Deployment and Upgrade

Data Characteristics

Monoclonal antibody quality documents include production batch records, inspection reports, stability study reports, process validation files, deviation records, change control documents, and annual product quality reviews. Data sources are typically structured or semi-structured files (PDF, Word, Excel) exported from Laboratory Information Management Systems (LIMS), Manufacturing Execution Systems (MES), and Quality Management Systems (QMS). Document update frequencies vary; batch records generate per batch, while stability reports may update quarterly or annually. Documents have strict structures, often containing fields such as batch number, production date, expiration date, test item, test method, test result, unit (e.g., mg/mL, IU/mL, %, pH value), acceptance criteria, and signatures.

Constraints on Deployment and Upgrade

Monoclonal antibody quality document characteristics impose specific requirements on FastGPT deployment and upgrades. First, the large volume of documents and specialized terminology demands text embedding models with strong domain understanding for accurate recall. Second, critical information like batch numbers and test results appears frequently in a fixed format. This requires a precise text segmentation strategy during knowledge base construction to avoid splitting key information. Third, document updates are not always synchronized. Some historical documents may need long-term retention alongside the latest revisions. This requires the system to handle multiple document versions smoothly during upgrades and support version rollback. Finally, diverse data sources (PDF, Word, Excel) require robust file parsers. These parsers must accurately extract text and table information from different formats, especially ensuring correct association of units with values in table data.

Configuration Guidelines

Configuration Item	Suggested Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	A single batch record or report can contain numerous charts and raw data, leading to large file sizes.
`maxContext`	`1500 characters`	Ensures complete understanding of long texts like monoclonal antibody production process descriptions and test methods, while avoiding redundancy from excessive length.
`Chunk size`	`300 characters`	Key information segments in batch records and inspection reports are typically of moderate length. Excessive length dilutes key points; insufficient length severs context.
`Recall count`	`Top 8 entries`	Given the complexity and cross-referencing in monoclonal antibody quality documents, increasing recall items helps cover more relevant context.
`Similarity threshold`	`0.75`	The domain is highly specialized, requiring a high similarity threshold to ensure recall results are highly relevant to the query intent.
`Rerank result count`	`Top 3 entries`	After reranking, selecting the few most relevant items improves the precision of the final answer.

Common Pitfalls

The application fails to respond or reports workflow error {"message":"Dangerous behavior"} after deployment. This may be due to FastGPT version incompatibility with custom workflow plugins, or incorrect model interface configurations in the workflow.
Knowledge base and application configurations are lost after a system restart. This typically occurs because the FastGPT container or service lacks persistent storage, leading to data loss when the container is destroyed.
After importing numerous Excel-formatted inspection reports into the knowledge base, some field values or units are incorrect. This happens because the default file parser has limited capability in handling complex table structures or merged cells, failing to correctly identify the correspondence between data columns and unit columns.

Validation Steps

Upload a monoclonal antibody inspection report PDF containing complex tables. Check if the text segmentation in the knowledge base is complete and if key fields like batch number, test result, and unit are correctly extracted.
For a stability study report, query the content or purity data for a specific batch at a particular time point. Observe if the model accurately recalls segments containing the corresponding values and units.
Simulate a deviation handling query, for example, "Reason" (reason) for abnormal purity in a certain batch. Check if FastGPT can extract and integrate information from relevant batch records, inspection reports, and deviation handling files.
After a FastGPT upgrade, run a predefined suite of integration test cases. These should include queries on different types of monoclonal antibody quality documents to ensure all functionalities and data integrity meet expectations.
