Deployment and Upgrade for Academic Promotion Clinical Trial

Data Characteristics

Data for academic promotion in clinical trial pre-screening primarily originates from research literature, clinical trial registries (e.g., ClinicalTrials.gov), drug inserts, medical guidelines, expert consensus, and internal pharmaceutical company research reports. Data update frequencies vary. Literature and guidelines might update quarterly or annually, while clinical trial registration information can have minor changes weekly or even daily. Document structures are diverse, including PDF papers, HTML web pages, structured database exports (e.g., CSV, JSON), and Word documents for internal reports. Fields and units are highly specialized, covering disease classifications (ICD-10), drug dosages (mg/kg), biomarker expression levels (ng/mL), and gene mutation sites, often with complex medical terminology and abbreviations.

Constraints Imposed by Data Characteristics on Deployment and Upgrade

The diversity of academic promotion data sources requires FastGPT to support robust heterogeneous data access during deployment. This includes parsing multiple file formats and handling various data source update mechanisms. High-frequency data updates, especially for clinical trial registration information, challenge the knowledge base's real-time synchronization and incremental update capabilities. This necessitates optimizing index rebuilding strategies to reduce system load. Complex and specialized document structures mean the knowledge base needs more refined text segmentation and entity recognition during parsing to accurately extract key medical information, avoiding semantic loss due to improper segmentation. The presence of specialized fields and units requires standardization and normalization during data preprocessing to ensure accurate retrieval and question answering, reducing the risk of model misinterpretation.

Configuration Settings

Configuration Item	Suggested Value	Rationale
`PARSE_FILE_TIMEOUT_SECONDS`	`600` seconds	To process large PDF literature and detailed reports, preventing parsing timeouts.
`Chunk size` (Segment Length)	`800`–`1200` characters	Balances the completeness of medical terminology with information density per segment, avoiding cutting off key concepts.
`Recall count` (Recall Count)	`10`–`15` items	Covers more potentially relevant professional literature snippets, improving recall rate.
`Similarity threshold` (Similarity Threshold)	`0.75`	Filters highly relevant medical text, reducing interference from irrelevant information.
`UPLOAD_FILE_MAX_SIZE`	`1000` MB	Accommodates the upload requirements for large PDF literature and dataset files.
`maxContext`	`32000` tokens	Accommodates more contextual information, processing complex clinical trial protocol descriptions.

Common Pitfalls

After a knowledge base document update, Q&A results still reference old information. This occurs when the incremental update mechanism is incorrectly configured or index rebuilding fails.
When encountering PDF documents with numerous tables or images, the parser errors or extracts incomplete content. This happens when the PDF parsing service fails to effectively handle complex layouts.
When Q&A involves specific drug dosages or biomarkers, the AI platform cannot provide accurate values or units. This is because specialized fields were not effectively identified and standardized during the data preprocessing stage.

Verification Steps

Upload representative academic documents of various types. Check if their content is fully parsed, especially if tables and image captions are correctly identified.
Manually trigger incremental updates of the knowledge base via API or interface. Verify that new data synchronizes promptly and reflects in Q&A results.
Construct queries containing specialized medical terminology, disease codes, and dosage units. Evaluate the accuracy and consistency of relevant fields in the AI platform's responses.
Check system logs to confirm no 504 Gateway Timeout or 429 Too Many Requests error codes appear during high-concurrency queries.
