What the Data for This Category Looks Like
Commercial vehicle financial report data primarily comes from periodic reports officially disclosed by listed companies, publicly available industry production and sales statistics documents, and structured financial report data from third-party compliant financial data platforms. The update rhythm falls into three categories: monthly sales announcements are updated once per month, quarterly reports once per quarter, and annual reports once per year.
Documents are typically in PDF format, including audit reports, consolidated financial statements, and segment operating data. Core fields include commercial vehicle segment revenue, sales volume of models such as heavy-duty trucks, light-duty trucks, and special-purpose vehicles, gross profit per vehicle, with corresponding units of ten thousand yuan, units, and yuan respectively.
Constraints Imposed on Multi-turn Dialogue and Prompting
Commercial vehicle financial reports have multiple pages per document, numerous segmented fields, and layered update cycles. These characteristics create multiple constraints for the multi-turn dialogue and prompting workflow.
First, limit the parsed length of a single uploaded document to avoid model loading timeouts. Second, for multi-dimensional data from segments such as heavy-duty and light-duty trucks, use prompts to guide users to gradually clarify the specific category and time range of their query. This prevents overly generalized responses. Third, for announcement data with different update cycles, proactively confirm the required report type during dialogue to ensure data matches user needs. Fourth, different fields correspond to different units. Clearly define unit labeling rules in prompts to avoid mismatches between numerical values and units.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Single commercial vehicle financial report PDFs typically do not exceed 300 MB, so this leaves reasonable buffer space |
maxContext | 8000–12000 characters | Structurally parsed text from commercial vehicle financial reports is relatively long, so a sufficient context window is required to handle multi-turn dialogue |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Long documents require additional time for text extraction and structured processing |
recall_top_k | Top 6–8 entries | Commercial vehicle financial reports have many segmented fields, so enough relevant paragraphs must be recalled to cover multi-dimensional query needs |
prompt_template | Commercial vehicle financial report analysis exclusive preset template | Guide the model to focus on commercial vehicle segment data and avoid confusion with data from other categories |
dialogue_history_max_length | 10–15 turns | Limit the length of multi-turn dialogue history to avoid excessive consumption of context window resources |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: A
413 Request Entity Too Largeerror is triggered during dialogue, or the model returns meaningless content. Cause: TheUPLOAD_FILE_MAX_SIZEormaxContextparameters are not configured, and no pre-validation interception is implemented for overly long inputs. - Symptom: Dialogue response results do not include the
cite_idsfield, making it impossible to trace the source of the corresponding financial report data. Cause: Theenable_citationconfiguration item is not enabled, or the prompt does not explicitly require marking the paragraph position of the data reference. - Symptom: After uploading supporting sales chart JPG files for commercial vehicle financial reports, the model cannot extract structured data from them. Cause: The
ALLOWED_EXTENSIONSconfiguration is not set to allow JPG format uploads, or the image OCR parsing module is not enabled.
How to Verify Proper Configuration
- Upload a standard commercial vehicle financial report PDF, check that the parsed text falls within the configured context window range, and confirm that the parsing process completed successfully.
- Initiate a multi-turn dialogue, gradually refining the query requirements (for example, first ask about overall revenue, then ask about cycle data for a specific vehicle segment), and check whether the model can reference historical dialogue information and provide corresponding results.
- Initiate a query that explicitly requires marking data sources, check whether the returned results include citation identification fields, and confirm that the citation configuration is active.
- Upload a properly formatted supporting chart file for commercial vehicle financial reports, check whether the parsing module can extract structured data from it, and confirm that file upload and parsing configurations are working correctly.
