Deployment and Upgrade for Stem Cell Therapy R&D Document

Data Characteristics

R&D documents in stem cell therapy originate from diverse sources, including clinical trial reports, patent literature, scientific papers, experimental records, and internal SOPs. These documents update frequently; clinical trial data, in particular, may update weekly. Document structures vary from rigorous ICH-GCP compliant reports to unstructured experimental notes. Fields and units are highly specialized, for example, cell line names, culture medium components, cell differentiation markers, dosage (e.g., 1x10^6 cells/kg), administration routes, follow-up periods (e.g., Day 28), and adverse event codes (e.g., CTCAE v5.0). Key metrics such as cell viability and purity are often expressed as percentages or specific counts. Experimental data may exist in multiple versions across different stages.

Constraints on Deployment and Upgrade

High update frequency requires the deployed system to support efficient data synchronization and incremental parsing, avoiding reprocessing historical data. Diverse document structures challenge the robustness of the parsing module; it must identify and process key information from various formats. Highly specialized fields and units necessitate deep integration of domain knowledge during model training and post-processing to ensure accurate entity recognition and relationship extraction. For example, the system must differentiate between various cell types and their specific markers, and correctly parse dosage expressions like 1x10^6 cells/kg. For multi-version documents, deployment must consider version control and historical data traceability to ensure the timeliness and accuracy of parsing results. Furthermore, processing large volumes of unstructured text imposes constraints on computational resources and storage capacity.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Stem cell therapy experimental reports and clinical trial documents often contain numerous charts and images, resulting in large file sizes.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Parsing complex structured documents is time-consuming and requires sufficient processing time.
`Chunk size`	`800–1200 characters`	Each segment must contain sufficient context, while avoiding excessive length that could lead to semantic drift, especially when processing experimental methods and results descriptions.
`Recall count`	`Top 10 entries`	Ensure the retrieval of enough relevant information, covering different dimensions of stem cell research data.
`Similarity threshold`	`0.75`	Given the prevalence of specialized terms and abbreviations, a higher threshold ensures retrieval precision and reduces interference from irrelevant information.
`Rerank result count`	`Top 5 entries`	Re-ranking further optimizes results from the initial retrieval, focusing on the most relevant core information, such as specific cell types or treatment protocols.

Common Pitfalls

Code execution nodes report Error: Timeout. This occurs when parsing complex documents or executing time-consuming scripts, and the default timeout setting is insufficient.
Key fields (e.g., 细胞株 or dosing amount) are empty in the parsing results. This usually indicates that parsing rules were not updated in time for changes in document structure, or the model failed to effectively recognize specific domain terminology.
After local deployment, accessing AIPROXY_API_ENDPOINT results in errors or connection failures. This may be due to incorrect AIPROXY_API_ENDPOINT or AIPROXY_API_TOKEN configuration, preventing proper pointing to or authentication with the AI proxy service.

Verification Steps

Upload a stem cell clinical trial report containing complex tables and specialized terminology. Verify that key data points (e.g., 主要终点, adverse event incidence rate) are correctly extracted in the parsing results.
Perform a retrieval query including cell line names and culture conditions. Verify that the recall and precision of the returned results meet expectations, and check that the Recall count matches the configuration.
Check system logs for PARSE_FILE_TIMEOUT_SECONDS related alerts or error messages to confirm that large document parsing does not time out.
