What This Category of Data Looks Like
Minor metal financial report data is primarily sourced from listed companies’ periodic reports, exchange public announcements, and industry association survey data. Core update cycles follow quarterly and annual schedules, with random updates triggered by temporary production capacity or price change announcements. Document structures include core financial indicator tables, detailed production and inventory records, raw material procurement costs, and product price fluctuation entries. Fields include metal grade proportion, physical tonnage, unit gross profit, and year-over-year change values. Common units are tons, yuan per kilogram, and yuan per ton.
Constraints on Vector Models and Indexing
The professional fields and update characteristics of minor metal financial reports create multiple constraints for vector models and indexing workflows. High-frequency, random temporary announcement updates require indexes to support incremental synchronization instead of full reconstruction. This avoids wasted computing resources from repeated calculations. Documents contain both structured tables and unstructured analysis text. Chunking rules must be configured to distinguish the two content types, preventing vector encoding from confusing professional terminology and general expressions. Professional fields such as metal grade and physical tonnage require vector models to adapt to non-ferrous metals sector terminology. Without this adaptation, retrieval accuracy will be insufficient. A single financial report has numerous structured data fields. Vector indexes must support multi-field associated retrieval to improve matching accuracy.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Minor metal financial reports include structured tables and unstructured analysis. This range balances the completeness of professional terminology and vector encoding density |
recall_top_k | Top 6–8 results | Minor metal financial reports have dense professional fields, so a sufficient number of segments must be retrieved to cover core indicators |
similarity_threshold | 0.72–0.78 | Adapts to semantic matching accuracy for professional terminology, and avoids retrieving irrelevant segments |
index_refresh_interval | 15–30 minutes | Matches the random update rhythm of temporary announcements, and balances index load and real-time performance |
enable_structured_parse | Enabled | Extracts fields such as metal production volume and cost tables from financial reports, and optimizes structured association for vector indexes |
UPLOAD_FILE_MAX_SIZE | 500 MB | Covers complete attachment content for a single annual financial report, and prevents upload truncation |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: In a locally deployed v4.9.0 knowledge base, document parsing and index enhancement options are not displayed. Cause: The open-source version does not enable commercial-exclusive parsing enhancement plugins by default. The corresponding feature switch must be enabled via the configuration file.
- Issue: Errors occur when calling the Embedding model via OneAPI, with 400 or 502 status codes returned. Cause: The model address configured in OneAPI does not adapt to professional terminology vector encoding requirements for the minor metal sector, or the interface timeout threshold is set too low.
- Issue: The number of knowledge base retrieval results is less than the configured
recall_top_kvalue. Cause: Structured parsing is not enabled, causing the semantic matching threshold for unstructured text to be incorrectly set too high, filtering out valid segments.
How to Verify Correct Configuration
- Upload a quarterly financial report PDF for a minor metal company, and check if structured fields such as metal production volume and unit cost are extracted after parsing.
- Initiate a financial report analysis query, and verify that the number of retrieved segments falls within the configured
recall_top_krange. - Submit a temporary announcement document, and check if the index completes updates within the set
index_refresh_intervaltime. - View OneAPI interface logs, and confirm that there are no timeout or format errors in Embedding model call requests.
