Data Characteristics for This Category
Financial report data for the IT services industry comes from periodic reports and temporary announcements publicly disclosed by domestic and overseas stock exchanges. These include annual reports, quarterly reports, and major business contract announcements, among others. Data update timelines follow regulatory requirements. Periodic reports are updated on a fixed quarterly and annual basis. Temporary announcements are released irregularly as company business developments occur. Individual documents are lengthy. They contain structured financial statements, business operation analysis, R&D investment details, risk warnings, and other sections. Core fields include security code, disclosure date, total revenue, segmented business revenue, attributable net profit, and more. Most units use ten thousand yuan or hundred million yuan as the measurement standard.
Constraints for Knowledge Base Retrieval and Recall
The mixed structured and unstructured format of IT services financial reports requires retrieval systems to support both full-text semantic matching and precise structured field recall. This prevents field matching bias caused by relying only on full-text retrieval. The coexistence of fixed update cycles and irregular temporary announcements requires the knowledge base to use a combined update mechanism: scheduled full synchronization plus incremental updates. This ensures complete historical data while enabling timely addition of the latest announcements. The complex structure of long documents and multiple tables requires text splitting rules to preserve table integrity and paragraph coherence. This avoids semantic fragmentation from excessive splitting, which reduces retrieval accuracy. The specialized nature of segmented business fields requires retrieval to prioritize matching industry-specific terms, such as cloud service revenue or operation gross margin. Recall weights for professional terminology must be configured.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | IT services financial reports contain long paragraphs of business analysis and multi-row/column financial tables. This range preserves complete rows of a single table or a coherent section of discussion, avoiding splitting-induced fragmentation |
recall_top_k | Top 8–12 results | Financial report analysis requires coverage of multiple dimensions such as revenue, R&D, and segmented business. This value balances recall accuracy and information redundancy |
similarity_threshold | 0.75–0.85 | Financial report terminology is highly specialized. This threshold filters low-relevance matching results while retaining accurate recall of domain-specific professional terminology |
sync_schedule | Trigger incremental sync at 2:00 AM daily | Temporary announcements from IT services companies are mostly released outside trading hours. Daily incremental synchronization ensures the timeliness of knowledge base data and avoids repeated imports of historical data |
structured_field_mapping | Map security code, disclosure date, total revenue, R&D investment | These fields are core retrieval dimensions for IT services financial report analysis, enabling precise structured recall and narrowing retrieval scope |
parse_table_enable | Enabled | IT services financial reports contain a large number of standardized financial tables. Enabling table parsing preserves retrieval accuracy for structured data and avoids loss of table information from plain text splitting |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Common Misconfigurations
- Issue: A
429 Too Many Requestserror is returned when calling the knowledge base. Cause:max_context_windowis not configured, or its set value is smaller than the total token count of single-round retrieval recall results. This exceeds the interface quota limit. - Issue: Knowledge base search response time exceeds 10 seconds. Cause: Structured field indexing is not enabled, and only full-text retrieval is performed on all long documents. This causes excessive system resource usage and reduced retrieval efficiency.
- Issue: Retrieval results include non-target company financial reports or unrelated industry news. Cause:
structured_field_mappingis not configured for field filtering, and only full-text retrieval is used to match irrelevant content. Precise targeting of target financial report data is not possible.
How to Verify Correct Configuration
- Upload a quarterly financial report PDF for an IT services company. Check if the parsed results retain the complete row and column structure of financial tables to confirm the
parse_table_enableconfiguration is correct. - Enter a structured retrieval query such as "2023 cloud service revenue". Check if retrieval results only return relevant segments from the corresponding financial report to confirm
structured_field_mappingis active. - Manually trigger an incremental synchronization task. Check if the knowledge base only adds financial report announcements released on the current day, with no duplicate imports of historical data, to confirm the
sync_scheduleand incremental synchronization logic are correct. - Adjust
similarity_thresholdto 0.8. Retrieve professional terminology such as "custom development gross margin". Check if the relevance of returned results meets business requirements to confirm the threshold configuration is reasonable.
