What data for this category looks like
Data related to coke financial reports primarily comes from three sources: publicly disclosed periodic reports of listed coal and coke enterprises, monthly operation briefs from industry associations, and data from coke and coal coke futures delivery warehouses. Update cycles vary by source:
- Futures data updates daily
- Industry briefs update monthly
- Listed company financial reports update quarterly, semi-annually, and annually
Document structure includes capacity planning, current output, cost composition, upstream-downstream linkage analysis, and other content. It contains both structured operational data tables and unstructured business analysis paragraphs. Field units include 10,000 tons/year, 10,000 tons, yuan/ton, 10,000 yuan, and similar units.
Constraints on knowledge base retrieval and recall
Large differences in update cycles across data sources require knowledge bases to use differentiated synchronization strategies per source. This prevents ineffective synchronization or data lag.
Target content in individual coke-related documents is scattered across multiple sections. When chunking long text, upstream-downstream associated semantics must be preserved to avoid semantic breaks that reduce recall accuracy.
Data formats vary significantly across sources, with both structured tables and unstructured paragraphs. Retrieval and recall must support content matching for mixed formats.
Coke business connections are strong. During recall, core business fields must be prioritized to avoid irrelevant content interfering with retrieval results.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk Length | 800–1200 characters | Coke financial report content is scattered and includes upstream-downstream connections. This length preserves semantic associations while avoiding excessive vector dimensionality |
Recall Count | Top 8–12 results | Coke business connections are strong. Too many recall results introduce irrelevant content, while too few fail to cover necessary information |
Vector Database Update Interval | Grouped by data source: 1 hour for futures data, 1 day for industry briefs, 7 days for financial report data | Large differences in update frequencies across data sources. Matches actual data release schedules |
Similarity Threshold | 0.72–0.78 | Coke business terminology has high distinctiveness. This threshold filters low-relevance results while retaining valid recall |
File Parsing Timeout | 600 seconds | Single coke industry brief or financial report files have large content volumes. This duration ensures complete parsing |
Maximum Single File Upload Size | 1000 MB | Meets upload requirements for multi-page coke financial reports or batch industry briefs |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific cases require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: Vector generation fails or recalled content has semantic breaks. Cause: Chunk length is not adjusted for the scattered content structure of coke financial reports. Using a generic fixed value destroys semantic integrity of upstream-downstream business associations.
- Symptom: Local content updates for single documents are not supported, only full file uploads are available. Cause: Incremental update strategies per data source are not configured. Only full synchronization mode is enabled, which fails to match local modification requirements of coke financial reports.
- Symptom: AI chat response time exceeds reasonable waiting thresholds. Cause: Recall count is set too high. The number of re-ranked returned results is not limited, leading to large amounts of redundant vector data participating in context splicing and increasing model inference load.
How to Verify Correct Configuration
- Upload a truncated single coke financial report document. Check parsed chunk results to confirm chunk boundaries do not break business-related paragraphs.
- Submit a retrieval request that includes coke prices and production capacity. Verify the number of recall results, and adjust configuration items to meet business coverage needs.
- Configure update tasks grouped by data source. Verify that synchronization cycles for futures data, industry briefs, and financial reports match actual release schedules.
- Review retrieval logs to confirm that recall result similarity falls within the preset range, with no low-relevance content included.
