Deployment and Upgrade for Laboratory Service R&D Document

Data Characteristics in this Category

Laboratory services generate highly specialized and diverse data within biomedical R&D. Data sources include experimental records, instrument reports, analysis results, and project reports. These typically exist in formats such as PDF, Word, Excel, and scanned images. Document update frequency depends on experiment cycles and project progress; updates can occur daily, weekly, or in batches. Document structures commonly feature titles, subtitles, tables, figures, formulas, and references. Tables frequently record experimental parameters, sample information, and detection data. Fields involve compound names, batch numbers, concentrations, temperatures, pH values, spectral data, cell line information, and detection indicators with units like nM, ℃, and ng/mL.

Constraints Imposed by these Characteristics on "Deployment and Upgrade"

Laboratory service document characteristics impose specific deployment and upgrade requirements. Inconsistent document update frequencies necessitate flexible incremental update mechanisms to avoid full re-parsing. Diverse document formats and complex internal structures, especially those with numerous tables and images, demand powerful multimodal processing capabilities and high-accuracy OCR technology from the parser. This ensures complete and accurate data extraction. The presence of specialized fields and units requires parsing models to identify and correctly extract these specific entities, and to handle unit conversion or normalization. This places higher demands on model fine-tuning and knowledge base construction. For deployment environments, data sensitivity typically requires on-premise deployment. This also demands computing resources, particularly GPUs, to support image processing and large model inference.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`200 MB`	Lab reports can be large, containing high-res images or extensive data
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Complex document parsing, especially OCR, takes time
`Chunk size` (Segment Length)	`800–1200 characters`	Balances semantic completeness of long texts and retrieval efficiency
`Recall count` (Recall Count)	`10 entries`	Ensures coverage of more relevant context for complex queries
`Similarity threshold` (Similarity Threshold)	`0.75`	Guarantees high relevance of recalled results to biomedical terminology
`Rerank result count` (Reranked Return Count)	`5 entries`	Refines final output, focusing on the most relevant information

Three Common Mistakes

Model response is slow, and logs show HTTP 504 Gateway Timeout. This occurs when configured GPU resources are insufficient to process complex document parsing and model inference requests in time, or the PARSE_FILE_TIMEOUT_SECONDS parameter is set too low.
Knowledge base query results show many missing or incorrect values for experimental data fields like concentration or batch number. This happens when OCR is not optimized for scanned documents or specific table structures, leading to inaccurate information extraction during structural parsing.
New accounts cannot be registered after on-premise deployment, and the interface displays Forbidden. This indicates AUTH_ENABLED or related registration parameters are not correctly configured in the docker-compose.yaml file, restricting user management functions.

How to Confirm Correct Configuration

Upload a PDF experiment report containing complex tables and figures. Check if key fields like compound name, detection indicator, and unit are complete and accurate in the structural parsing results.
Execute a knowledge base query with specialized terminology. Check if the response time is acceptable and evaluate if the relevance and accuracy of the returned results meet expected thresholds.
Attempt to create and log in with a new user account in the on-premise deployment environment. Confirm user management functions operate normally.
Check system logs to confirm no Timeout or Internal Server Error status codes appear during file upload and parsing.
