What the Data for This Category Looks Like
Financial report data for the power grid equipment category comes primarily from public annual reports, quarterly reports and exchange temporary announcements issued by listed companies. Industry associations release industry operation data as supplementary sources. Data updates follow a fixed schedule: quarterly reports launch within one month after each quarter ends. Listed companies must disclose annual reports by the end of April of the following year. A single financial report includes standard financial statement chapters, plus power grid equipment-specific business sections. These sections cover fields such as UHV equipment production capacity, transmission and transformation component shipment volume and grid-connected project revenue. Common units include units, GW and ten thousand yuan, which are standard in this industry. Temporary announcements focus on events like major project bids and capacity expansion. They are short but highly targeted.
Constraints for Citation Sources and Traceability
Fixed update schedules require the traceability system to automatically match report release time ranges. This prevents the system from citing expired or not yet officially disclosed data. Exclusive business fields require the traceability system to accurately locate paragraphs related to power grid equipment. This lets the system distinguish this content from generic financial material. Long document lengths require the system to support locating citation fragments by business segment or chapter. This avoids scattered traceability information. Temporary announcement release schedules require the traceability system to support real-time crawling and association with corresponding report entities. This ensures citation timeliness and accuracy. Multiple supplementary data sources require the traceability system to clearly mark each data disclosure subject. This prevents confusion between information from different sources.
How to Configure
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 8-12 entries | Single power grid equipment financial reports have lengthy content after chunking. Too many recall results create redundant traceability information. Too few results fail to cover core business segment data |
Similarity threshold | 0.75-0.85 | Power grid equipment financial report fields have high professionality. A high threshold filters irrelevant matches and avoids returning unrelated generic financial content |
Chunk size | 1000-1500 characters | Power grid equipment financial report business segment paragraphs are lengthy. Too short segment length destroys business logic integrity. Too long segment length impairs accurate positioning |
Rerank result count | Top 3-5 entries | Prioritize displaying the most relevant power grid equipment-specific business paragraphs. This avoids non-core content interfering with traceability |
PARSE_FILE_TIMEOUT_SECONDS | 300-600 seconds | Single financial report documents have large volume. Parsing requires longer time to complete chunking and field extraction |
ENABLE_DOC_SOURCE_SHOW | Enabled | Mandatory display of citation source document name, release time and paragraph location must be enabled to meet traceability requirements |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: The system returns financial fragments related to UHV production capacity as citation sources, even when the query has no connection to the core business of power grid equipment financial reports. Cause: The
Similarity thresholdis set below 0.7. The system fails to filter matches with low semantic relevance, leading to irrelevant content being recalled. - Phenomenon: Chunked parsed documents lose exclusive field information such as grid-connected equipment production capacity and UHV project revenue. Cause: The
Chunk sizeis set too short. This splits complete business segment paragraphs into meaningless fragments, leading to broken field information. - Phenomenon: Citation sources only display the document name, without marking release time and paragraph location. Cause: The
ENABLE_DOC_SOURCE_SHOWconfiguration is not enabled. The traceability information display function remains inactive.
How to Verify Correct Configuration
- Upload a financial report document of a listed power grid equipment company. Check if the chunked parsed content includes exclusive fields such as grid-connected equipment production capacity and UHV revenue. Confirm that the chunking logic follows business segment division.
- Submit a query related to power grid equipment financial reports. Verify that the citation sources in the returned results mark the document name, release time and paragraph location. Confirm that traceability information is complete.
- Submit a query unrelated to power grid equipment financial reports. Verify that the system does not return financial report-related content. Confirm that the
Similarity thresholdconfiguration works as expected. - Check the document parsing log. Confirm that parsing time does not exceed the preset
PARSE_FILE_TIMEOUT_SECONDS, and no timeout errors occur.
