What the data for this category looks like
Personal care product data sources include public filing documents from brands, ingredient reports issued by third-party testing institutions, product packaging labeling information, and compliance announcements published by regulatory authorities. Data updates are triggered by new formula launches, compliance standard adjustments, or batch updates, with no fixed cycle. Most documents are in PDF format, containing ingredient details, compliance inspection items, usage guidelines, and batch traceability information. Fields include ingredient name, concentration proportion, production batch number, filing number, shelf life unit, and others.
What constraints these characteristics impose on the "knowledge base retrieval and recall" link
Multi-source and heterogeneous data sources require the retrieval pipeline to support cross-data-source field alignment, to avoid recall results where ingredient information does not match compliance information. No fixed update cycle requires the knowledge base to support on-demand incremental synchronization, to adapt to real-time synchronization needs for new formulas or compliance updates. Fields with units require retrieval configuration to support precise matching of numerical items with units, to avoid confusion between ingredient data using different measurement units. Structured detailed content in documents requires retaining the associative integrity of fields during segmented retrieval, to avoid losing the corresponding relationship between ingredients and concentrations after splitting.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | The maximum volume of a single personal care test report or compliance announcement usually does not exceed 500 MB. This setting avoids invalid resource usage |
chunk_size | 800–1200 characters | Most personal care documents contain short paragraphs such as ingredient details and inspection items. This segment length can retain the associative integrity of ingredients and concentrations |
recall_top_k | Top 6–8 results | Personal care due diligence reports need to cover multi-dimensional information including ingredients, compliance, and batches. An appropriate number of recall results balances comprehensiveness and relevance |
similarity_threshold | 0.75–0.85 | Matching between ingredient and compliance information requires high accuracy. This threshold filters low-relevance non-target content |
PARSE_IMAGE_ENABLE | Enabled | Personal care documents often contain visual information such as ingredient lists and packaging images. Enabling this setting allows hidden text to be extracted via OCR |
INCREMENTAL_SYNC_MODE | On-demand trigger | Personal care data updates have no fixed cycle. On-demand synchronization reduces unnecessary resource consumption |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: Personal care product packaging and ingredient list images added to the knowledge base do not display after retrieval. Cause: The
PARSE_IMAGE_ENABLEconfiguration is not enabled, or OCR functionality is not enabled during parsing, resulting in unextracted image text that the front end cannot render. - Phenomenon: Matching results that confuse "0.5% niacinamide" and "0.5mg niacinamide" appear in retrieval results. Cause: Field indexing with units is not enabled, or precise matching rules are not configured, resulting in separate matching of values and units.
- Phenomenon: A
504 Gateway Timeouterror is triggered when loading a personal care compliance summary document with more than 500 pages at one time. Cause: TheUPLOAD_FILE_MAX_SIZEorPARSE_FILE_TIMEOUT_SECONDSparameters are not adjusted, and the default configuration cannot adapt to the parsing and upload duration of long documents.
How to confirm the configuration is complete
- Upload a single personal care test report PDF under 500 MB, and check whether core text content such as ingredient lists and inspection items is extracted after parsing.
- Enter a search term combining the target ingredient and concentration, and verify that the recall results only match document fragments of the corresponding fields.
- Trigger an on-demand incremental synchronization, and check whether newly uploaded personal care compliance announcements are automatically updated to the knowledge base.
- View the number of returned retrieval results, and confirm that they fall within the preset recall count configuration range.
