Data Characteristics for This Product Category
Culture media and consumables product data typically originates from supplier product catalogs, Technical Data Sheets (TDS), Safety Data Sheets (SDS), and internal inventory management systems. Data update frequency is relatively stable, with version iterations usually occurring quarterly or semi-annually. Information such as product batches and expiration dates may update daily. Document structures are primarily PDF, Excel, or XML formats. Fields include product name, catalog number, specifications, packaging, main ingredients, storage conditions, application areas, batch number, production date, and expiration date. Units involve volume (mL, L), weight (g, kg), concentration (mM, %), pH value, and temperature (°C). Different suppliers may use non-standardized unit abbreviations.
Constraints Imposed by These Characteristics on "Workflow Orchestration"
Diverse data sources and inconsistent formats require the workflow to have robust multi-format parsing capabilities during data ingestion, especially for text extraction and table recognition from unstructured PDF documents. Varying update frequencies necessitate a workflow designed for periodic triggering and incremental updates, capable of identifying and merging new and old data versions to avoid duplication and conflicts. The extensive use of specialized terminology and abbreviations in product documentation requires the language model within the workflow to accurately understand the biomedical domain context. The diversity of fields and units demands higher requirements for entity recognition and information extraction modules, requiring configuration of specific unit conversion rules (e.g., unifying "Milliliter" from different suppliers to "mL") to ensure consistent query results. Additionally, time-sensitive information like batch and expiration dates requires integration of real-time data interfaces during queries, ensuring their priority over static product catalogs.
Configuration Guidelines
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
fileParserStrategy | StructuredAndUnstructured | Accommodates both tabular data and text descriptions in PDF technical specifications. |
maxChunkSize | 800 characters | Adapts to paragraph lengths in technical documents, preventing individual chunks from being too long and losing context, while retaining sufficient information. |
chunkOverlap | 100 characters | Ensures context continuity, especially at the junctions of content like ingredient lists and application descriptions. |
retrievalTopK | 7 items | Balances precision and recall, covering multiple product attributes a user might be interested in. |
similarityThreshold | 0.75 | Filters out irrelevant or weakly related product information, improving answer quality. |
temperature | 0.3 | Prioritizes factual accuracy in product inquiry scenarios, reducing the risk of model hallucination. |
Three Common Pitfalls
- When a user queries a product, the answer lacks batch or expiration date information because the workflow relies solely on static product catalogs and does not integrate real-time inventory or batch management systems.
- The model's response to product specifications shows unit confusion, such as misidentifying "milliliters" as "grams." This occurs because the entity recognition module in the workflow lacks standardized conversion rules for biomedical units.
- Uploading a large technical document results in a
400 Bad Requesterror. This is due to theUPLOAD_FILE_MAX_SIZEparameter being set too low, causing the file size to exceed the limit.
How to Verify Configuration
- Select typical user queries covering various product specifications, batches, and application scenarios. Verify the workflow's output for accuracy and completeness.
- Upload technical documents in different formats (PDF, Excel) and sizes (e.g.,
10 MB,50 MB). Check if the workflow can parse and ingest them correctly without errors. - For queries containing ambiguous units (e.g., "ml", "mL") or abbreviations (e.g., "PBS"), verify if the model can correctly understand and provide answers with unified units.
