What the data for this category looks like
Commercial vehicle financial report analysis data sources primarily include publicly available periodic reports of listed commercial vehicle enterprises, announcement documents disclosed by exchanges, and segmented production and sales public data released by industry institutions. Data updates follow regulatory disclosure rules and industry release rhythms. Periodic reports are updated on a fixed quarterly and annual basis, while monthly production and sales data is released monthly. Most documents are in PDF format, with structures containing financial statement main text, discussion and analysis of operating conditions, business segment reports and other sections. Commercial vehicle-related content is concentrated in chapters such as main business composition, segmented model production and sales, and cost composition. Fields include model classification, current period sales, current period revenue, per-vehicle cost, regional sales data, etc. The unit of sales is units, and the units of revenue and cost are ten thousand yuan.
What constraints do these characteristics impose on model access and configuration
The data characteristics of commercial vehicle financial reports impose clear constraints on model access and configuration. The presence of multiple model classifications and segmented business fields requires configuring context window parameters adapted to multi-entity extraction, to avoid breaks in the association between model and revenue data caused by long text truncation. The fixed document structure of PDF format allows configuration of chapter extraction rules for document parsing, to targetedly capture commercial vehicle-related sections and reduce interference from irrelevant content. The fixed-cycle update rhythm requires configuring timed synchronization parameters matching the disclosure cycle, to avoid conflicts between data pulling and update logic. The clear units of segmented sales and revenue require configuring unit verification rules for numerical extraction, to ensure unit consistency of extraction results.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–16000 characters | The segmented business section text of commercial vehicle financial reports is relatively long, requiring sufficient context to retain associations between model classification, revenue and sales data, and avoid information truncation |
PARSE_CHAPTER_RULE | Extract the "Main Business Composition", "Production and Sales Data", and "Cost Composition" chapters | Core analysis data of commercial vehicle financial reports is concentrated in the specified chapters, and targeted crawling reduces interference from irrelevant content |
UPLOAD_FILE_MAX_SIZE | 50 MB | The typical size of a single commercial vehicle annual or quarterly financial report PDF does not exceed this threshold, preventing upload failures |
ENTITY_EXTRACT_THRESHOLD | 0.75 | There are many commercial vehicle model classifications, requiring a relatively high threshold to filter non-target entities and ensure the accuracy of extracted model and revenue fields |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing long PDF documents requires sufficient time to avoid parsing interruptions caused by timeouts |
SCHEDULE_SYNC_INTERVAL | 90 days (quarterly financial reports), 365 days (annual financial reports) | Matches the fixed disclosure cycle of commercial vehicle financial reports, ensuring data synchronization frequency aligns with update rhythm |
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, and it is recommended to test on your own samples before finalizing settings.
Three common errors
- An error with the
software.amazon.awssdk.services.bedrockruntime.model.prefix appears when Claude series models deployed via Amazon Bedrock are called. This occurs because model access permission parameters are not configured correctly, preventing the SDK from normally calling the Bedrock interface. - The workflow text extraction component cannot extract model classification fields from commercial vehicle financial report PDFs. This occurs because entity extraction rules matching the structure of commercial vehicle financial reports are not configured, preventing the model from recognizing specific classification tags.
- When configuring the DeepSeek Chat model, the generated analysis content only includes text descriptions and cannot output visual content such as pie charts and bar charts. This occurs because the model's tool call configuration is not enabled, or trigger rules for visual generation are not specified, preventing the model from calling chart generation capabilities.
How to confirm the configuration is complete
- A local commercial vehicle financial report PDF is uploaded, and the document parsing result is checked to confirm whether it only includes the content of the specified chapters, verifying that the chapter extraction configuration is effective.
- A text extraction task is run, and the extracted model, sales, and revenue fields are checked to confirm they are complete and their units meet business requirements, verifying that the entity extraction and context window configuration match the needs.
- A timed synchronization task is triggered, and the time interval of data pulling is checked to confirm it aligns with the configured synchronization interval, verifying that the synchronization logic is normal.
- The model is called to generate analysis content for a single financial report, and verification is performed to confirm whether the model can correctly associate models with corresponding revenue and sales data, verifying that the long text processing configuration meets the requirements.
