What this category’s data looks like
Commercial vehicle financial report data primarily comes from quarterly and annual financial report announcements publicly disclosed by listed commercial vehicle enterprises, as well as public statistical materials from industry regulatory authorities and national commercial vehicle industry associations. Data update cycles follow these rules: quarterly financial reports are updated every 3 months, annual financial reports are updated once per year, and supporting industry data is updated monthly. A single financial report document includes modules such as core operating indicators, production and sales data for segmented vehicle models, revenue and cost breakdowns, and cash flow status. Field units are mostly "units" (for sales or production capacity), "ten thousand yuan" (for revenue or cost), and "units/year" (for production capacity). Segmented vehicle model fields distinguish categories such as heavy-duty trucks, light-duty trucks, and special operation vehicles.
Constraints imposed by these characteristics on citation sources and traceability
The multi-source and heterogeneous nature of commercial vehicle financial reports requires the traceability link to clarify priority and identification rules for different data sources. This prevents confusion between enterprise financial reports and industry statistical data during recall. The complex field structure with many segmented vehicle models requires traceability to bind specific vehicle categories and corresponding data sources. This prevents cross-category data misuse. Data sources with different update cycles must carry accurate timestamp markers during traceability. This ensures the timeliness of recalled data matches the time range of user queries. The lengthy structure of financial report documents requires traceability to accurately locate specific content paragraphs. This prevents mismatches between traceability information and output content. The strong correlation between segmented fields in commercial vehicle financial reports requires accurate matching of associated indicators and vehicle models during traceability. This prevents traceability errors such as mismatched production and sales data and revenue breakdowns.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_top_k | Top 8-12 entries | Commercial vehicle financial reports have many segmented fields. A sufficient number of recalled fragments is needed to cover different vehicle models and indicators |
source_tag_field | data_source | Commercial vehicle financial reports have multiple data sources. This field marks source types such as enterprise financial reports or industry associations |
chunk_size | 800-1200 characters | A single segment of commercial vehicle financial report content contains multiple sets of associated indicators. This length preserves complete context for fields and segmented vehicle models |
similarity_threshold | 0.75-0.85 | This range adapts to semantic differences in segmented fields of commercial vehicle financial reports, preventing recall of irrelevant data |
timestamp_field | publish_date | Different data sources have different update cycles. This field filters valid data that matches the query time range |
enable_source_verify | Enabled | Commercial vehicle financial reports have high data accuracy requirements. Enabling this setting ensures traceability verification confirms cited sources are authentic |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration errors
- Residual "Citation: [1]" text appears in output content. This happens when the automatic rendering switch for traceability markers is not disabled, and original markers are directly included in the final output.
- Logs cannot distinguish commercial vehicle financial report data from different sources. This happens when the
source_tag_fieldparameter is not configured, and no dedicated identifiers are added for enterprise financial reports or industry association data. - Generated citation IDs are forged and invalid. This happens when the
enable_source_verifyparameter is not enabled, and no authenticity verification is performed on recalled data sources. IDs are directly generated without linking to actual documents.
How to verify correct configuration
- Access the knowledge base configuration interface, confirm that
source_tag_fieldandtimestamp_fieldare mapped to the corresponding business fields of commercial vehicle financial report data. - Initiate a query that includes a specific commercial vehicle segmented category, check that traceability information in the output only links to matching data sources, with no cross-category data mixed in.
- Review system operation logs, confirm that each traceability record carries clear source type and release time markers, with no missing or confused information.
- Test query text of different lengths, confirm that recalled fragment lengths meet configuration requirements, with no truncation or overflow.
