Multi-turn Conversations and Prompts for Culture Media and

Data Characteristics for This Category

Pharmacovigilance data for culture media and consumables primarily originates from registration documents submitted by manufacturers, post-market surveillance reports, user feedback, and relevant regulatory databases. This data typically exists as a mix of structured and unstructured formats. Structured data includes product batch information, production dates, expiration dates, ingredient lists, intended uses, and adverse event codes (e.g., MedDRA). The update frequency is influenced by batch production and regulatory requirements. Unstructured data consists of detailed user reports, laboratory analysis results, product manuals, and technical specification documents, ranging from a few pages to hundreds of pages in length. Field units are diverse, such as batch numbers, temperature units (℃), concentration units (mg/L), pH values, and expiration dates (year/month/day), sometimes including specific industry standard codes.

Constraints Imposed by These Characteristics on Multi-turn Conversations and Prompts

The granularity and rapid updates of batch information in culture media and consumables data require multi-turn dialogue systems to quickly index and identify the latest batch-related adverse event reports. The unstructured nature and diverse descriptions in user feedback challenge the generalization and semantic understanding capabilities of prompts, requiring accurate extraction of key information from vague descriptions. The extensive technical details, specialized terminology, and cross-references within documents necessitate stronger long-text processing capabilities and domain knowledge embedding for the dialogue system to understand context. For example, when a user mentions "abnormal pH in a certain batch of culture medium," the system must link to the production records and quality control reports for that batch and identify "pH" as a specific parameter and its normal range. This directly impacts the accuracy of entity recognition and relationship extraction in prompts. Diverse units and encoding systems also require prompts to effectively handle unit conversions and encoding mappings.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`maxContext`	`8000–12000 characters`	Ensures coverage of typical adverse event reports and related product manual content.
`Chunk size` (Segment Length)	`600–800 characters`	Balances semantic completeness with recall efficiency, adapting to the paragraph structure of technical documents.
`Recall count` (Recall Count)	`8–12 items`	Balances relevance with information coverage, avoiding omission of critical batch information.
`Similarity threshold` (Similarity Threshold)	Calibrated by actual measurements `0.75–0.85`	Differentiates adverse event characteristics of different batches or similar products.
`Rerank result count` (Reranked Return Count)	`Top 5 items`	Focuses on the most relevant product batches, adverse event descriptions, and handling suggestions.
`API_TIMEOUT_SECONDS`	`600 seconds`	Accommodates response times for parsing large technical documents and complex queries.

Three Common Mistakes

Dialogue logs show successful API calls but empty content. The reason is an excessively high Similarity threshold (Similarity Threshold) in the upstream knowledge base, leading to a failure to recall relevant adverse event data.
When a user asks about adverse reactions for a specific batch of culture medium, the system returns general information. This occurs because the Batch Number field is not recognized. The prompt template fails to effectively guide the model to extract and match precise batch information from unstructured text.
Document parsing takes too long, causing dialogue timeouts. This manifests as an API_TIMEOUT_SECONDS error. The reason is an overly large Chunk size (Segment Length) setting, where the amount of data processed in a single operation exceeds system capacity.

How to Confirm Proper Configuration

Simulate user inquiries about adverse reactions or quality issues for specific batches of culture media or consumables. Check if the returned results accurately link to reports for that batch.
Input vague descriptions containing specialized terms and units. Observe if the dialogue system can correctly identify and interpret this information, for example, whether "high pH value" can be linked to relevant quality standards.
Test the system's response speed and information extraction accuracy when processing lengthy user feedback reports. Verify if key fields such as Adverse Event Code are identified in the report.
