What data looks like for this category
Data sources for cultural and entertainment supplies include compliance guidelines released by industry associations, product filing documents from manufacturers, product detail pages on e-commerce platforms, and authorization certificates from copyright registration authorities. Updates happen in real time when new products launch. Industry compliance requirements update every quarter. Copyright authorization information adjusts according to cooperation cycles. Document structures include product SKU information, material composition test reports, copyright numbers, and dealer qualification documents. Fields include "cultural and entertainment product category code", "authorization validity period", "material proportion", and "suggested retail price". Units include millimeters, pieces, yuan, and years, among others.
What constraints do these characteristics impose on the knowledge base retrieval and recall link
Multi-source heterogeneous data sources require the knowledge base to support mixed parsing of structured parameters and unstructured text. This avoids retrieval failure caused by differences in data source formats. Frequently updated content requires configuration of incremental recall and regular full synchronization rules. This ensures the information used in due diligence reports uses the latest version. Complex nested document structures require associative field matching during retrieval. This prevents information loss caused by broken parameter matching. Special field units require unified format calibration before recall. This avoids inaccurate retrieval results caused by unit differences.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Cultural and entertainment supplies documents often include long-text material test reports and copyright statements, which require longer parsing time |
chunk_size | 800–1200 characters | Cultural and entertainment supplies documents contain many linked product parameters and copyright numbers. Segments that are too long lose semantic connections. Segments that are too short damage information integrity |
similarity_threshold | 0.72–0.80 | Similar products in the cultural and entertainment supplies category have relatively high parameter similarity. A threshold that is too low introduces irrelevant documents. A threshold that is too high misses valid recall results |
recall_top_k | Top 8 results | Intelligent due diligence reports need to cover multi-dimensional content including product qualifications, compliance information, and market parameters. Too few recall results miss critical information |
rerank_top_n | Top 3 results | Due diligence reports need to focus on core compliance and qualification information. Reranking retains the most relevant retrieval results |
UPLOAD_FILE_MAX_SIZE | 500 MB | Test reports for cultural and entertainment supplies often include high-definition image attachments, leading to large single-file sizes |
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 specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Misconfigurations
- Phenomenon: A large number of abnormal documents appear after knowledge base training. Training status shows failure. The interface returns
413 Request Entity Too Large. Cause: TheUPLOAD_FILE_MAX_SIZEparameter is not adjusted. Large-volume product test reports fail to upload, interrupting the training process. - Phenomenon: Only 50,000 records are returned when exporting the knowledge base. Full documents cannot be obtained. Cause: The
EXPORT_BATCH_SIZEparameter is not configured. The default batch export threshold is set to 50,000. - Phenomenon: The chat box cannot upload files in an intranet deployment environment. The interface shows connection timeout. Cause: The
client_max_body_sizeparameter is not adjusted in the nginx reverse proxy configuration. This limits the maximum file upload size.
How to Confirm Proper Configuration
- Upload a single cultural and entertainment supplies test report with a volume exceeding 300 MB. Check whether the upload status is normal. Confirm that the
UPLOAD_FILE_MAX_SIZEparameter adapts to file volume requirements. - Select all abnormal documents to trigger one-click retraining. Check the processing results of abnormal documents in the training log. Confirm that the retraining process takes effect.
- Export all knowledge base documents. Check whether the total number of export records covers all uploaded files. Confirm that the batch export parameter configuration is reasonable.
- Upload files through the reverse proxy address in the intranet environment. Check whether the upload progress and results are normal. Confirm that the nginx proxy configuration adapts to file transmission requirements.
