What the data for this category looks like
Glass industry research report data primarily comes from public statistics released by industry associations, securities firm industry analysis documents, and monthly operational reports from manufacturing enterprises. Update frequency adjusts based on industry trends. Updates become more frequent during peak seasons or when new policies are released. Under normal conditions, updates occur 1 to 2 times per month, with in-depth analysis documents published quarterly. Document structures typically include segmented product descriptions, market pricing, inventory data, production capacity information, policy impact analysis, and other modules. Fields include float glass ex-factory prices, inventory turnover days, monthly shipment volumes, and more. Field naming varies slightly across different documents. Some documents use both weight boxes and square meters as area units.
What Constraints These Characteristics Impose on Knowledge Base Retrieval and Recall
Glass industry research report data sources are scattered, covering multiple channels such as industry associations, securities firms, and manufacturing enterprises. Differences in document formats and field naming across sources require the retrieval and recall process to support unified mapping and classification filtering for multi-source data. There are many segmented product categories and inconsistent field units. Precise matching rules must be set for categories such as float glass and tempered glass to avoid invalid cross-category recall. Update frequency fluctuates significantly. Bulk updates may generate large numbers of new documents. The knowledge base must support efficient incremental synchronization and parallel parsing to prevent task blocking. Some in-depth research reports have long lengths. Sufficient contextual association must be retained during segmented retrieval to avoid information fragmentation.
How to Set Configurations
| Config Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Single glass research report PDF or DOCX files typically do not exceed 100 MB. This setting reserves reasonable redundancy for bulk uploads |
PARSE_SEGMENT_LENGTH | 800–1200 characters | Glass research reports include long paragraphs of pricing analysis and production capacity data. Excessively long segments will lose contextual association |
RECALL_TOP_K | Top 8 entries | There are many segmented product categories for glass research reports. Sufficient segmented dimensions are needed to match retrieval requirements |
SIMILARITY_THRESHOLD | 0.72–0.78 | Balances precision and recall coverage to avoid missing relevant research reports for segmented product categories |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing large, in-depth research reports takes significant time. This setting prevents parsing tasks from timing out and being interrupted |
RERANK_TOP_N | Top 4 entries | Re-ranks recall results to focus on high-value content related to core product categories |
UPLOAD_PARALLEL_NUM | 6 | Adapts to concurrent requirements for bulk uploads, preventing task queue blocking from single-threaded execution |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific scenarios require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: Manually inserted knowledge base indexes disappear automatically after several hours. Cause: Persistent storage configuration for the knowledge base is not enabled. Temporary indexes are only stored in memory cache and not written to a persistent database.
- Symptom: Upload queues become blocked and task execution delays are high when bulk uploading DOCX or PDF research reports. Cause: The
UPLOAD_PARALLEL_NUMparameter has not been adjusted to a value suitable for bulk tasks. The number of concurrent upload threads is insufficient. - Symptom: Retrieval results include non-glass category construction materials research reports, and accurate matching to target categories is not possible. Cause: Product category metadata filtering rules are not enabled. Retrieval and recall do not bind field tags exclusive to the glass product category.
How to Confirm Configurations Are Correctly Set
- Upload a single glass research report, check the generated document metadata after parsing, and confirm that exclusive fields are extracted and match the original document content.
- Initiate a bulk upload test, check the parallel execution status in the task management interface, and confirm that the configured parallel thread count takes effect.
- Search for keywords for a specified glass segmented product category, and verify that the metadata tags of returned results match the preset filtering conditions.
- Check the knowledge base index status after 24 hours, confirm that no automatic disappearance occurs, and verify the effectiveness of the persistent storage configuration.
