What this category of data looks like
Data for power grid equipment financing daily reports is sourced from listed power grid equipment company announcements, power grid company bid winning announcements, industry association research materials, and official financing platform disclosures. Updates occur daily. Each daily report covers all fully disclosed financing events from the current day. Document structure includes these core fields: full and short names of financing subjects, financing amount (unit: ten thousand yuan or hundred million yuan), financing round, fund provider name, announcement release date, corresponding power grid project region, and equipment sub-categories. The length of individual financing entries and the total length of aggregated daily report documents vary significantly. It is recommended to confirm parameters based on sample statistics and actual testing of local datasets.
What constraints these characteristics impose on knowledge base retrieval and recall
The daily update requirement means retrieval systems must support incremental updates. This avoids resource waste from fully re-parsing historical documents. Multi-field structured data means retrieval must support filtering by specified fields. Examples include recalling only financing events for transmission tower sub-categories, or limiting query time ranges to the last seven days. Mixing of full and short names for financing subjects means retrieval must support synonym matching. Short individual entries but long aggregated documents means retrieval must accurately locate core field content. This avoids redundant recall of irrelevant paragraphs. Multiple channels reposting the same financing event means retrieval must support document deduplication. This prevents duplicate results from interfering with user judgment.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Incremental Update Switch | Enabled | Power grid equipment financing daily reports update daily. Incremental updates reduce parsing and storage time |
Recall Count | Top 8 entries | Individual financing entries are concise. 8 entries cover most daily financing events and avoid redundant results |
Similarity Threshold | 0.75–0.85 | Financing announcement texts have high similarity. A too-low threshold introduces irrelevant information. A too-high threshold misses similar announcements |
Reranked Return Count | Top 5 entries | Core financing information concentrates in the first 5 entries. Reranking prioritizes displaying highly relevant content |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | A single daily financing report aggregate document contains announcements from multiple enterprises. Parsing takes a long time |
Document Deduplication Threshold | 0.90 | The same financing announcement may be reposted across multiple channels. This threshold effectively filters duplicate documents |
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 issues require targeted analysis. It is recommended to perform actual testing on local datasets before finalizing settings.
Three common configuration mistakes
- Phenomenon: The number of knowledge base retrieval results is fixed and cannot be adjusted to the quantity required by the business. Cause: The
Recall Countparameter is not configured correctly, or the global reference upper limit is mistakenly set to a fixed value. - Phenomenon: The reranking model cannot be called during the large model dialogue process, but the independent knowledge base search test page runs normally. Cause: The reranking model switch is not enabled in the knowledge base configuration associated with the large model, and configuration was only completed in the independent test page.
- Phenomenon: Duplicate financing announcement entries appear in retrieval results and cannot be removed via interface settings. Cause: The document deduplication threshold is not configured, or the threshold is set too high, causing duplicate documents to not be filtered.
How to confirm correct configuration
- Upload a daily power grid equipment financing report document, trigger incremental update, and check whether the update time of the document in the knowledge base list matches the upload operation time.
- Enter a test query, such as "2024 Q3 power grid equipment financing events", and verify whether the number of returned results matches the configured
Recall Countvalue. - Enter the same query in the knowledge base search test page, compare the retrieval results returned during the large model dialogue process, and confirm that the sorted results have consistent ranking.
- View the source information of retrieval results, confirm that each result is associated with the original document’s file name and release date, and that sources can be traced normally.
