Model Access and Configuration for Pharmacovigilance in

Data Characteristics for This Category

Process validation pharmacovigilance data originates from clinical trial reports, production batch records, quality control reports, and regulatory compliance documents. Data updates are infrequent, typically summarized after validation batch production or revised when regulations or processes change. Document structures are complex, containing detailed experimental data, analysis results, batch information, and adverse event reports. Fields are diverse, covering patient characteristics, drug dosage, production parameters, adverse reaction types, severity, occurrence time, and treatment measures. Units include measurements, time, and percentages.

Constraints from These Characteristics on "Model Access and Configuration"

The complexity and diversity of process validation data require robust heterogeneous data parsing capabilities for model access to accurately extract key information. Complex document structures necessitate significant effort in data preprocessing to convert unstructured text into analyzable fields. Infrequent updates mean model training and knowledge base updates do not need to be frequent, but each update must ensure comprehensiveness and accuracy. The unique nature of fields and units requires the model to identify and correctly convert different units when processing numerical data, preventing misinterpretation due to unit inconsistencies. For example, drug dosages might be expressed in milligrams (mg) or grams (g) and require standardized handling.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`maxContext`	`2048 token`	Process validation documents are detailed; a longer context is needed to understand relationships.
`Chunk size` (Segment Length)	`500–800 characters` (characters)	Ensures each text segment contains sufficient information while avoiding redundancy from excessive length.
`Recall count` (Recall Count)	`Top 8 entries` (top 8)	Pharmacovigilance events have many associated factors; increasing recall improves relevant information coverage.
`Similarity threshold` (Similarity Threshold)	`0.75`	Ensures recalled results are highly relevant to the query intent, reducing unnecessary noise.
`Rerank result count` (Rerank Return Count)	`Top 3 entries` (top 3)	After reranking, focus on the most relevant core information to improve answer precision.
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Process validation reports can contain numerous charts and detailed data, leading to large file sizes.

Three Common Errors

Missing critical drug dosage or time units in model output. This occurs when unit information in text is not correctly identified or standardized during data preprocessing.
Failure to link specific adverse events to production batches when processing batch-related queries. This happens when the association between batch information and adverse events is not sufficiently extracted and indexed during knowledge base construction.
Excessive response time or timeouts when the model answers user queries about "adverse reaction and production process parameter correlation." This occurs due to an overly large maxContext configuration or an unreasonable Chunk size (segment length) setting, leading to an excessive retrieval and inference burden.

How to Confirm Correct Configuration

Submit queries containing drug dosages with different units (e.g., milligrams, grams, milliliters). Verify that units in the model's output are consistent and correct.
Upload a process validation report containing multiple batch details and adverse events. Query for adverse events related to a specific batch. Check if the model can accurately associate and provide relevant information.
For complex multi-conditional queries (e.g., the occurrence of a certain adverse reaction under specific production parameters), observe the model's response time and result completeness. Ensure accurate information is provided within an acceptable delay.
