Data Characteristics for this Category
Monoclonal antibody product data primarily originates from biomedical literature, clinical trial reports, patent databases, and pharmaceutical company internal R&D documents. This data typically exists as unstructured text, semi-structured tables, and structured database records. The update frequency is high due to the continuous discovery of new antibodies, clinical advancements, and expanded indications, with new literature and trial data published monthly. Document structures are complex, encompassing molecular structures, target information, mechanisms of action, pharmacokinetics, pharmacodynamics, safety data, manufacturing processes, and quality control standards. Fields and units involve specific biochemical and pharmacological metrics such as protein sequences (amino acids), molecular weight (Da), affinity (Kd or EC50, in M or nM), half-life (hours), dosage (mg/kg), and purity (%).
Deployment and Upgrade Constraints Imposed by These Characteristics
The complexity and diversity of monoclonal antibody data impose specific requirements on FastGPT's deployment and upgrade processes. The wide range of data sources necessitates robust multi-format file parsing capabilities, especially for PDF literature and reports. Continuous updates demand efficient incremental indexing and version management mechanisms to ensure knowledge base timeliness. Complex document structures and specialized fields, such as antibody sequences or affinity data, require meticulous text preprocessing and embedding strategies to accurately capture semantic information. Incorrect character set encoding or tokenizer configuration can lead to professional terminology recognition failures. Furthermore, private deployment scenarios heighten data security and compliance requirements, necessitating encrypted data transmission and storage, along with strict access control. File parsing defects in older versions or incompatibility of basic plugins with new data types can manifest as functional anomalies after an upgrade, such as chart generation failures or inability to import files.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Monoclonal antibody-related literature and reports are often large, requiring support for big file uploads. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing complex PDFs or large reports can be time-consuming. |
Segment Length | 800–1200 characters | Balances contextual completeness with embedding model processing capacity, preventing semantic loss. |
Recall Count | Top 8 | Ensures retrieval of sufficient relevant information, covering various aspects. |
Similarity Threshold | 0.75 | Balances recall precision with generalization ability, reducing interference from irrelevant content. |
Rerank Return Count | Top 3 | Optimizes the accuracy and conciseness of the final presentation, highlighting the most relevant results. |
Three Common Pitfalls
- Symptom: After a system upgrade, some existing monoclonal antibody product manuals fail to parse, showing "file parsing failed." Reason: The new version's file parser has changed compatibility with specific encodings or PDF structures, or lacks corresponding dependencies.
- Symptom: When querying about antibody affinity, the answer lacks key numerical information or outputs "none." Reason: Structured or semi-structured affinity data in the knowledge base was not correctly extracted and indexed, preventing specific numerical fields from being matched during retrieval.
- Symptom: In a local deployment environment, the file upload progress bar freezes or ultimately fails when uploading large clinical trial reports. Reason: The
UPLOAD_FILE_MAX_SIZEconfiguration is too small, or the server's temporary storage space is insufficient, preventing complete reception of large files.
How to Verify Proper Configuration
- Upload a PDF clinical trial report for monoclonal antibodies containing complex tables and charts. Confirm successful parsing and full-text retrieval.
- Query the knowledge base for key fields such as targets, mechanisms of action, and molecular weights of different antibodies. Verify that answers contain correct and specific numerical values or descriptions.
- Simulate a high-concurrency scenario by simultaneously uploading multiple large documents. Observe the response time of file upload and parsing services to ensure no timeouts or anomalies.
- Check FastGPT backend logs to confirm no critical errors related to encoding, format, or memory occurred during file parsing.
