What the Data for This Category Looks Like
Minor metals financial report data primarily comes from annual and quarterly reports of listed companies both domestic and overseas, as well as monthly supply and demand briefings released by non-ferrous metal industry associations. Quarterly financial reports are publicly available 1-2 months after the end of each quarter. Annual financial reports must be disclosed by the end of April of the following year. Monthly industry supply and demand data is updated in the latter half of the current month. Document structures include management business analysis, consolidated financial statements, and minor metals-specific fields such as production volume, inventory, import and export volume, and spot price. Units are mostly tons, yuan per ton, ten thousand tons, and similar units.
What Constraints Do These Characteristics Impose on Multi-turn Conversation and Prompt Engineering?
The multi-source data characteristics, varying update rhythms, and specialized fields of minor metals financial reports impose multiple constraints on multi-turn conversation and prompt configuration. Dispersed multi-source data requires switching between data sources multiple times during multi-turn conversations, so prompts must clearly specify data source priorities. The large differences in data update rhythms mean multi-turn conversations need to distinguish timeliness labels for quarterly financial reports and monthly industry data to avoid mixing expired information. There are many specialized fields, so prompts must explicitly require extraction of minor metals-specific indicators such as production volume and inventory, rather than only general financial fields. Individual financial report documents are lengthy, so the multi-turn conversation context window must support long-text parsing to avoid truncating critical data.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | A single minor metals annual report often contains over 5000 characters of financial statements and industry analysis, requiring coverage of complete parsed content |
recall_top_k | Top 6–8 results | Minor metals financial reports need to cover multiple specialized dimensions including production volume, inventory, and import and export volume, requiring sufficient relevant documents to be recalled |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Financial report documents contain multiple tables and long text paragraphs, with longer parsing time than general documents |
system_prompt_template | Template including requirements for extracting minor metals-specific fields | Must explicitly require output to include minor metals-specific financial indicators such as production volume, inventory, and spot price |
UPLOAD_FILE_MAX_SIZE | 20 MB | Single minor metals listed company annual report PDFs often exceed 10 MB, requiring allowance for uploading complete documents |
re_rank_top_n | Top 3–4 results | Re-rank recalled multi-source documents to prioritize the latest monthly industry data and latest quarterly reports |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and testing on local samples prior to finalization is recommended.
Three Common Misconfigurations
- Symptom: The application returns a prompt stating "Incorrect API Key used". Cause: The global universal API Key was mistakenly used for conversation calls, instead of the application-specific API Key.
- Symptom: The dialog box displays the error "Cannot read properties of null (reading 'q')". Cause: The multi-turn conversation context transfer configuration is missing, causing the user query field to not be read correctly.
- Symptom: The question classification node in the workflow fails to accurately identify minor metals financial report-specific prompts. Cause: The prompt did not explicitly limit the analysis scope to the minor metals category, causing the model to confuse general financial reports and minor metals-specific indicators.
How to Verify Proper Configuration
- Upload a minor metals listed company annual report PDF, verify that the parsed text includes specialized fields such as production volume and inventory to confirm the parsing configuration is active.
- Initiate a multi-turn conversation, sequentially request quarterly production volume and monthly inventory data, confirm that the system can distinguish data sources across different time dimensions to verify the context configuration is active.
- Use the application-specific API Key to send a conversation request, confirm that the returned result does not include a 401 status code to verify the API Key configuration is correct.
- Configure a question classification node in the workflow, input a prompt related to minor metals financial reports, confirm that the classification result matches the preset financial report analysis category to verify the prompt configuration is active.
