What the Data for This Category Looks Like
Sources of jewelry investment research data include official brand product manuals, industry association process standard documents, raw material market briefings, and offline exhibition promotional materials. Data update schedules adjust with new product launches and raw material price fluctuations. No fixed update cycle exists, but most updates occur monthly or quarterly. Most documents use docx or pdf formats. Some product parameter tables are submitted as excel files. Document structures include structured parameter pages, image annotation pages, and process description paragraphs. Fields cover material purity, item weight, product dimensions, and process types. Common units include grams, millimeters, pieces, and similar measurements.
Constraints Imposed by These Data Characteristics on Parsing and Chunking
Jewelry data characteristics create multiple constraints for the document parsing and chunking workflow. First, documents contain large volumes of product photos and process diagrams. The parsing engine must support image OCR extraction and link extracted text to corresponding text blocks. This prevents disconnection between images and their associated text. Second, structured parameter groups and long process descriptions appear together. Chunking must preserve semantic unit integrity, and cannot forcibly separate parameters from their accompanying descriptions. Third, diverse unit fields must retain contextual links during chunking. This ensures parameters and their units remain paired during subsequent retrieval. Finally, frequently updated documents require the parsing workflow to support incremental chunking. This avoids full repeated processing of existing documents.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_IMAGE_ENABLE | Enabled | Jewelry documents often include product photos and process diagrams. Text within images must be extracted and linked to text blocks |
CHUNK_SIZE | 800–1200 characters | Jewelry documents contain long process descriptions and structured parameter groups. This length preserves semantic integrity and avoids separating parameters from their corresponding descriptions |
CHUNK_OVERLAP_RATIO | 15% | Cross-chunk process descriptions and raw material-related paragraphs require contextual continuity. A 15% overlap ensures semantic coherence |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Large jewelry product manuals include multiple pages of images and text. Sufficient time is needed to complete parsing and chunking |
MAX_CHUNK_PER_DOC | Set based on document page count | Prevents excessive indexing redundancy from too many chunks per document, and adapts to differences in jewelry document page counts |
TEXT_SPLITTER_MODE | Split by semantic paragraphs | Parameter groups and process descriptions in jewelry documents are independent semantic units. Splitting by paragraphs preserves business relevance |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Issue: After uploading a docx-format jewelry product manual, embedded product photos display the
Invalid image fileerror message. Cause: ThePARSE_IMAGE_ENABLEconfiguration is not enabled, or the image format is not universally supported. The parsing engine cannot extract text linked to these images. - Issue: When submitting multiple jewelry document parsing tasks, only one 3090 GPU is used. A second GPU does not join the task pool. Cause: The
PARSE_GPU_DEVICESparameter is not configured to specify available GPUs, or the multi-GPU parallel parsing switch is not activated. Resources are not fully utilized. - Issue: After uploading an excel file with product parameter tables, units such as weight and dimensions are missing from parsing results. Cause: The structured table parsing switch is not enabled, or cell context is not preserved during chunking. Units become separated from their associated parameters.
How to Confirm Proper Configuration
- Upload a docx-format jewelry product manual that includes embedded images. Check that parsing results include OCR text from images, and no
Invalid image fileerrors are present. - Review the chunk count for a single document. Confirm the chunk count aligns with the document page count and paragraph length, with no obvious missing process descriptions or parameter paragraphs.
- Export the parsed chunked text. Verify that units for fields such as material purity and item weight match the original document, with no separation of units and parameters.
- Submit multiple jewelry documents in pdf, excel, and docx formats. Confirm the parsing engine handles all formats correctly and completes chunking successfully.
