What Data for This Category Looks Like
Data sources for jewelry research reports include public research reports for segmented textile and apparel subcategories, supply chain documents disclosed by brands, and statistical materials from offline industry exhibitions. Update cycles adjust based on industry exhibition schedules and brand financial report release timelines. Most documents are multi-page PDFs or long docx files, containing structured tables (raw material quotes, SKU parameters), paragraph-form trend analysis, and fragmented industry news snippets. Fields include material type, per-gram cost, SKU number, and channel shipment volume. Units include gram, yuan per gram, piece, and batch number. Some documents include high-resolution product photos, which increases overall file size.
Constraints on Document Parsing and Chunking
Mixed document sources combine structured tables and unstructured paragraphs. Parsing must accurately distinguish boundaries between the two content types, to avoid splitting table cells across different chunks. Long documents often include cross-page supply chain data and trend analysis. Chunking must retain contextual connections, to prevent key parameters and their associated descriptions from being separated. High-value fields such as material type, per-gram cost, and SKU number must be bound to their parent paragraphs. Chunk granularity must match the information density of these fields. Some documents include high-resolution product photos, which increases computing power consumption during parsing. The system must adapt to processing pressure for large files, to avoid timeouts or resource exhaustion.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Jewelry research reports often include high-resolution images and multi-page tables. Parsing takes longer than generic documents, and 900 seconds covers processing for most large files |
maxChunkSize | 800–1200 characters | High-value fields and explanatory paragraphs in jewelry research reports are mostly within 800 characters. This range retains field associations and avoids excessive splitting |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single supply chain document files from some brands can reach 1500 MB. This threshold covers conventional large document upload requirements |
enable_table_parse | Enabled | Raw material quotes and SKU parameters in jewelry research reports are presented in table form. Enabling this retains the integrity of structured data |
chunk_overlap | 100–150 characters | Cross-page supply chain data requires leading and trailing overlap to ensure contextual association during retrieval |
marker_gpu_memory_threshold | 4 GB | Parsing high-resolution images in jewelry research reports requires at least 4 GB of video memory, to avoid video memory overflow errors |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: An error
timeout of 360000ms exceededappears in the interface when uploading PDF research reports larger than 10 MiB. Cause: ThePARSE_FILE_TIMEOUT_SECONDSvalue has not been adjusted to match jewelry research reports. The default timeout duration is insufficient for processing long documents with high-resolution images. - Phenomenon: Some docx-format brand analysis documents have no content or missing fields after parsing. Cause: The docx-compatible parsing engine has not been configured, or the table parsing switch has not been enabled, preventing structured content in the documents from being recognized.
- Phenomenon: Some cells in material quotation tables are split across different chunks after the knowledge base is uploaded. Cause: The
maxChunkSizevalue is too small, forcibly splitting table content that spans multiple cells and destroying the integrity of structured data.
How to Verify Proper Configuration
- Upload a single large jewelry research report PDF, and check if the parsing task completes within the preset timeout period.
- Upload a docx-format supply chain document, and confirm that all table cell content is fully retained in the parsing results.
- Randomly select a chunk containing material parameters, and verify that the chunk includes both the material type and corresponding cost data, without forced splitting.
- Check the parsing engine's running logs, and confirm that GPU video memory usage does not exceed the preset threshold, with no video memory overflow related errors.
