What the Data for This Category Looks Like
Financial report data for power grid equipment comes from publicly disclosed periodic reports and temporary announcements from domestic and overseas stock exchanges, plus industry operation data released by industry associations. Updates follow fixed quarterly, semi-annual, and annual schedules, with immediate updates for major business changes. Document structures include structured financial tables, category-specific business breakdown explanations, and attachments for production capacity and order data. Fields cover numerical values such as equipment model, rated capacity, unit cost per unit, and delivery cycle. Units include kilowatts, yuan, days, and others.
Constraints Imposed on Knowledge Base Retrieval and Recall
The high proportion of structured content, wide variation in document span, and clear update schedules for power grid equipment financial reports create multiple constraints for retrieval and recall. Structured financial tables and segmented business fields require precise matching, so metadata retrieval capabilities must be enabled. Individual annual reports have long length, so they need to be split while retaining context associations for business segments, to avoid truncation of critical data. Fixed-period periodic reports and real-time updated temporary announcements require distinct full and incremental update rules, to avoid re-scanning old data or missing newly disclosed winning bid notices and production capacity change information. Category-specific fields such as rated capacity and unit cost per unit need retrieval weights set higher than general text, to improve accurate recall rates.
Configuration Settings
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1024 MB | The typical size of a single power grid equipment financial report document (including multi-page attachments) does not exceed 1024 MB, which meets the import needs of most disclosure files |
maxContext | 800–1200 characters | Business segment paragraphs in power grid equipment financial reports are typically 800–1200 characters long. Splitting documents this way retains complete revenue structure explanations and avoids context breaks |
recall_top_k | 6–10 entries | Segmented business data for power grid equipment financial reports is scattered across multiple sections. Recalling 6–10 entries covers relevant information for most business segments and avoids redundancy |
similarity_threshold | 0.75–0.85 | Precise fields such as power grid equipment model and rated capacity require a high similarity threshold to avoid recalling irrelevant general power equipment data |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large annual report documents takes significant time. 600 seconds covers parsing needs for most complex formats |
enable_structured_parse | Enabled | Power grid equipment financial reports contain large amounts of structured financial tables and business data. Enabling this option extracts metadata fields for precise retrieval |
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. Each scenario requires individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- An error "File size limit exceeded" appears when uploading power grid equipment financial reports, and documents larger than 1024 MB cannot be imported. The cause is failure to adjust the
UPLOAD_FILE_MAX_SIZEparameter, which uses a too-low default value. - When searching for data related to "rated capacity" for power grid equipment, recall results are empty or contain large amounts of irrelevant civil power equipment content. The cause is failure to enable structured parsing, failure to set the
similarity_thresholdthreshold, or failure to configure retrieval weights for category-specific fields. - In a private deployment environment, the number of recall results returned by the retrieval API call is fixed at 6 entries, and the quantity cannot be adjusted via parameters. The cause is failure to modify the
recall_top_kparameter in the private deployment configuration file, which has a default limit of 6 entries.
How to Verify Correct Configuration
- Upload a sample power grid equipment financial report document, verify that the upload and parsing process works normally, and confirm that the file size limit configuration matches the actual size of the current document.
- Enter category-specific search keywords, check the relevance of recall results, and adjust similarity and recall count parameters to a range that meets business needs.
- Trigger an incremental update task, verify that newly disclosed announcements are synchronized to the knowledge base, and confirm that the update rule configurations are correct.
- Call the retrieval API, pass test keywords, and confirm that the number of returned results matches the configured parameters.
