What data for this category looks like
Financial report data for investment platforms primarily comes from public exchange disclosure documents, official announcements of listed companies, and original financial report documents parsed by the platform in compliance with regulations. Updates follow quarterly and annual regular disclosure schedules, with real-time updates for temporary performance announcements and major event announcements. Document structures include structured financial report tables, explanatory notes, and unstructured management discussion and analysis content. Core fields cover financial report periods, operating revenue, attributable net profit, earnings per share, and similar items. Units primarily use yuan, ten thousand yuan, and hundred million yuan. Some cross-currency financial reports include exchange rate conversion annotations.
Constraints on vector models and indexing
The mixed structured and unstructured nature of financial report data requires vector models to support semantic encoding for both pure text paragraphs and table cells, preventing loss of association relationships after structured indicators are split. High-frequency regular and temporary updates require indexes to support incremental refreshes, reducing computing resource consumption and ensuring data timeliness. Precise retrieval needs across multiple fields require vector index recall logic to associate specific financial report fields; relying solely on global semantic matching may not meet analysis accuracy requirements. Additionally, single financial report documents have considerable length, so reasonable segmentation granularity must be controlled to retain complete contextual information for core indicators.
Configuration Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
embedding_model | Doubao-embedding-v2 or a locally deployed general embedding model | Financial reports include structured tables and long text paragraphs; this type of model can adapt to semantic encoding of multi-format text |
chunk_size | 800-1200 characters | Financial report paragraphs are mostly long sentences. Too short segmentation will destroy the contextual association of core indicators such as revenue and net profit. Too long segmentation will exceed the model input length limit |
chunk_overlap | 100-200 characters | Financial reports have strong indicator linkage across paragraphs. Overlapping segmentation can retain semantic association between adjacent paragraphs and improve recall accuracy |
index_refresh_interval | Hourly | Temporary announcements have irregular update frequencies. Hourly incremental refresh balances timeliness and computing resource usage |
top_k | Top 8-12 results | Investment analysis needs to cover multi-dimensional financial report data. Too many recall results will introduce irrelevant fragments. Too few results will fail to cover complete analysis dimensions |
PARSE_TABLE_ENABLE | Enabled | Financial reports contain a large amount of structured table data. Enabling table parsing allows cell content to be encoded as vectors separately, improving the accuracy of indicator retrieval |
The parameter values provided on this page are common recommended starting points 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
- Symptom: Index progress stalls after switching vector models, and switching back to the original model is not possible. Cause: Old index metadata cache was not cleared first. Switching models directly causes index configuration conflicts.
- Symptom: A
404 page not founderror is returned after configuringDoubao-embedding. Cause: The API request address was not configured correctly, or the call permission for the corresponding model was not activated, resulting in model call failure. - Symptom: Vector indexes are not updated synchronously after financial report images in the knowledge base are updated. Cause: The
IMAGE_EMBEDDING_ENABLEconfiguration was not enabled, or the incremental index update process was not triggered.
How to Confirm Configurations Are Correct
- Navigate to the settings page of the target knowledge base, and verify that core configuration items including
embedding_modelandchunk_sizematch preset values. - Upload a single standard financial report sample, trigger manual index construction, and confirm that the interface progress bar advances normally to completion.
- Input core financial report keywords such as quarterly revenue, and check that recall results include associated field content from the corresponding reporting period.
- Upload a temporary announcement file, wait for the configured refresh interval, then initiate a search to confirm that new content is covered by the index.
