What Data for This Category Looks Like
Data sources for textile manufacturing intelligent due diligence reports include factory production ledgers, customs declarations, supply chain cooperation contracts, third-party quality inspection reports, and public industry capacity information. Data update frequency varies by type: production ledgers are updated daily, customs declarations and contracts are updated as needed, and quality inspection reports are updated per batch. Document structures include structured tables, unstructured PDF reports, and on-site photos. Core fields include yarn count, loom speed, grey fabric weight, with corresponding units of count, revolutions per minute, and grams per square meter.
Constraints Imposed on Vector Models and Indexes
The mixed structured and unstructured document structure requires vector models to support semantic embedding of structured fields and segmented embedding of non-long texts. Industry-specific terms and units require embedding models to adapt to the semantic features of the textile manufacturing niche, to avoid semantic misinterpretation of terms like yarn count and loom speed by general-purpose models. High-frequency updated production data requires indexes to support incremental refreshes, to avoid resource consumption from full index rebuilding. Demand for batch upload of multiple files requires index systems to support sharded storage and concurrent processing, to prevent overload of single-batch tasks.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk Length | 800–1200 characters | Textile manufacturing due diligence reports include long-form process descriptions and structured ledger snippets. Segments that are too long will lose field associations, while segments that are too short will damage the semantic integrity of industry terms. |
Chunk Overlap Rate | 10–15% | Cross-segment process parameter associations require retained context, and overlapping segments prevent semantic breaks. |
Recall Count | Top 10–15 results | Due diligence report searches mostly target precise matches for specific processes or supply chain nodes. Too many recall results will introduce irrelevant low-similarity data. |
Similarity Threshold | 0.72–0.80 | Semantic similarity of textile manufacturing industry terms is relatively high. A threshold that is too low will introduce similar data from non-target product categories. |
INDEX_REFRESH_INTERVAL | 3600 seconds | Core data such as production ledgers is updated daily. Scheduled index refreshes ensure the timeliness of retrieved data. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large textile quality inspection report PDFs takes significant time. A timeout will cause parsing failures. |
The parameter values provided on this page are common recommended 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 Misconfigurations
- Symptom: After upgrading FastGPT from version 4.9 to 4.10, the existing textile manufacturing knowledge base cannot trigger vector retrieval, and searches return no results. Cause: The vector dimensions of the new version's embedding model are incompatible with the vector format generated by the old version's index, and automatic index rebuilding is not performed.
- Symptom: After uploading a batch of textile production ledger files, the server crashes. After restarting, the knowledge base index status remains "not ready" and no automatic indexing actions occur. Cause: Batch upload concurrency limits and shard sizes are not configured. The number of files in a single batch exceeds the server's carrying capacity, and unfinished indexing tasks are not automatically restored after restarting.
- Symptom: When searching for textile process parameters, results mix similar terms from synthetic fiber and pure cotton categories, and matching accuracy is insufficient. Cause: The similarity threshold is not adjusted for the specialized terminology of the textile manufacturing industry, causing similar texts with low semantic relevance to be recalled.
How to Confirm Proper Configuration
- Upload a single textile quality inspection report document, and check if the parsed segmented content fully retains the semantic information of core fields such as yarn count and loom speed.
- Trigger a manual index refresh, wait for the task to complete, and check if the vector index status of the knowledge base shows "ready".
- Enter a search term containing a specific textile process term, and verify that the number and similarity of recall results match the preset configuration.
- Simulate batch upload of multiple production ledger files, confirm that server load does not exceed the threshold and indexing tasks start automatically.
