What data in this category looks like
Financing daily report data for the professional services sector mainly comes from public regulatory disclosure documents, industry association research summaries, official corporate financing announcements, and third-party financial databases. The data updates daily. Each daily report document covers all industry financing events of the day. Documents are mostly structured tables, with fields including financing party name, financing amount, financing round, investor list, disclosure date, affiliated sub-sector. Amount units are uniformly ten thousand yuan or hundred million yuan. Date fields follow the YYYY-MM-DD format. Some supplementary fields include financing purpose and investor background introduction.
What constraints do these characteristics impose on the "knowledge base retrieval and recall" link
Structured daily report data requires retrieval to prioritize precise field matching, and avoid broad semantic association that recalls non-target financing events. The daily update feature requires the knowledge base incremental sync link to support daily scheduled triggers, to prevent data lag from affecting retrieval timeliness. High-dimensional features brought by multi-field structures require setting field weight differentiation during the recall phase, for example, taking financing amount and financing round as high-priority matching items. At the same time, unified unit and date formats require format standardization during the preprocessing phase, to avoid matching failure caused by inconsistent units or incorrect date formats.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall Count | Top 10 | The number of disclosed events on a single day for professional services financing daily reports is usually in the dozens. Too many recalled entries will increase the context processing load of the large model. The top 10 entries can cover core information |
Similarity Threshold | 0.75–0.85 | Structured data requires high matching accuracy. This interval can filter low-relevance entries and avoid irrelevant financing events from mixing into retrieval results |
Chunk Length | 800–1200 characters | The structured content length of a single financing event is moderate. This chunk interval can retain field relevance and avoid splitting that destroys information integrity |
Incremental Sync Cycle | Daily 02:00 | Financing daily report data is usually summarized in the early morning of the same day. Syncing in advance can ensure daytime retrieval timeliness and avoid data lag |
Field Weight Configuration | Financing amount:1.5, financing round:1.2, other fields:1.0 | Users in the professional services field focus on financing scale and rounds. Increasing the matching weight of corresponding fields can optimize recall accuracy |
Reranked Return Count | Top 3 | Reduce large model input redundancy, focus on the most matching core financing events for user queries, and improve response efficiency |
The parameter values provided on this page are conventional recommendations used to determine the 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 the settings.
Three common mistakes
- Phenomenon: AI conversation responses do not reference knowledge base content, only output general answers. The
rag_contextfield in logs is empty. Cause: The incremental sync configuration is not correctly associated with the financing daily report data source, so knowledge base entries updated on the day cannot be loaded during the conversation phase. - Phenomenon: Non-current-day historical financing events are mixed into retrieval results, and the
publish_datefield of the returned results does not match the query time range. Cause: No date filter condition is added during the retrieval link, or date format standardization is not completed during preprocessing. - Phenomenon: Uploaded financing daily report image format files cannot be parsed, and the interface shows a
parse_failederror. Cause: OCR parsing configuration is not enabled, or the structured table in the image is not correctly identified as retrievable fields.
How to confirm the configuration is complete
- Manually trigger an incremental sync, check the data source update log in the knowledge base management interface, confirm that the daily financing daily report file has been successfully parsed and indexed.
- Submit a test query that includes specific financing rounds and amount ranges, verify whether the field matching degree and time range of the retrieval results meet expectations.
- Check the citation source markers in the large model response, confirm that the returned content includes the financing daily report entries retrieved from the knowledge base.
- Check the preprocessed field data, confirm that date, amount and other formats have been standardized, with no unit or format ambiguities.
