What data for this category looks like
Vehicle manufacturer financial report data mainly comes from official investor relations platforms of vehicle manufacturers and domestic and overseas securities exchange disclosure systems. Updates follow fixed quarterly and annual cycles, with temporary sales announcements and major project progress announcements released simultaneously. The document structure includes three core parts: consolidated financial statements, production and sales data details, and discussion and analysis of operating conditions. Fields cover revenue amount, attributable net profit, vehicle production and sales volume, R&D investment amount, and more, mostly using units of yuan and units of volume.
What constraints these characteristics impose on multi-turn dialogue and prompting
The coexistence of fixed-cycle financial reports and temporary announcements requires multi-turn dialogue to support switching context scope based on reporting period and announcement type. Complex document structures and long single-page content require limiting the number of document chunks retrieved per turn to avoid context overload that interferes with core logic. Fields include two types of indicators with different units: production and sales volume and monetary amount. Prompts must clearly specify statistical caliber and units to prevent indicator confusion. Temporary announcements have strong timeliness, so the dialogue process must support quick retrieval of the latest disclosed non-periodic report content.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall count | Top 8-12 entries | Vehicle manufacturer financial report documents are lengthy. Too many retrieved entries will cause context overload, while too few will fail to cover core financial and production-sales data |
similarity threshold | 0.72-0.80 | There are many financial report fields and similar expressions. A threshold that is too low will introduce irrelevant documents, while a threshold that is too high may miss relevant segmented field content |
maxContext | 6000-8000 characters | The core content length of a single vehicle manufacturer financial report is large, so sufficient context must be retained to support logical coherence of multi-turn questions |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Vehicle manufacturer financial reports include multiple detail sheets, which take longer to parse. The default timeout duration is insufficient for complete parsing |
chunk length | 1000-1200 characters | Financial statements and production-sales details in financial reports must be split by module. An overly long chunk will cause redundant context after retrieval, while an overly short chunk will destroy data relevance |
reranked return count | Top 5-7 entries | The financial report modules most matching the current dialogue topic must be returned first to avoid information confusion during multi-turn dialogue |
The parameter values provided on this page are conventional recommendations used as a starting point 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 Mistakes
- After increasing
recall countorreranked return count, the large language model output does not reference any retrieved content. ThemaxContextparameter is not adjusted synchronously, and too many retrieved entries exceed the context window limit, causing the system to automatically truncate retrieved data, so the large language model cannot obtain valid reference sources. - After using a knowledge base dialogue API key, the interface displays an unauthorized prompt, and the interface returns a 401 status code. The API key is not bound to the access permissions of the corresponding knowledge base, or the key configuration is not synchronized to the deployment environment.
- A timeout error occurs when parsing a vehicle manufacturer financial report, returning the
PARSE_FILE_TIMEOUTerror code. ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted to a sufficient duration, causing the parsing of long detail sheets to be terminated before completion.
How to Confirm Correct Configuration
- Upload a single complete vehicle manufacturer financial report document, check the number of segmented sections and module division after parsing, and confirm that the segmentation configuration adapts to the document structure.
- Initiate multi-turn questions covering production-sales data and financial indicators, check whether the large language model output accurately associates retrieved content from the corresponding reporting period, and confirm that retrieval and context configurations are reasonable.
- Call the API interface to test the authorization status, check whether the returned
statusfield is a success identifier, and confirm that the API key permission configuration is correct. - Enable the streaming output switch, test whether the content is returned character by character during the dialogue process, and confirm that the streaming configuration is effective.
