What the data for this category looks like
The data for coke financing daily reports is sourced from official daily reports released by domestic bulk commodity spot trading platforms and futures warehouse operators, as well as financing ledger data from cooperating financial institutions. It updates with a full refresh of the previous day’s data every early morning. Documents primarily use structured tables, including fields such as report date, category identifier, origin information, ex-warehouse settlement price, port storage price, financing amount, financing period, and related fields for credit subjects. For units: price fields use yuan/ton, financing amounts use ten thousand yuan, and financing periods use natural days.
What Constraints These Characteristics Impose on Multi-turn Dialogue and Prompt Engineering
The daily full refresh feature of coke financing daily reports requires that multi-turn dialogue must limit the time range of recalled data to the last 24 hours, to avoid mixing data across different days. The structured document field structure requires that prompts must explicitly specify the format for extracting dedicated fields such as ex-warehouse settlement price and port storage price, to prevent large models from confusing field correspondences. The multi-source data feature requires that prompts must explicitly prioritize official warehouse and financial institution ledger data, to avoid interference from non-authoritative content. The category-specific origin and storage-related fields for coke require that multi-turn dialogue must retain the category identifier in context, to prevent field misalignment during cross-category queries.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 8 entries | The daily data entries for coke financing daily reports are limited. Too many recalled entries will introduce irrelevant content, while too few will result in insufficient coverage |
Similarity threshold | 0.72–0.78 | Structured documents have high requirements for field matching accuracy. This range can filter low-relevance non-coke category financing data |
maxContext | 1200–1500 characters | Single documents for coke financing daily reports are moderate in length. This range retains sufficient context while avoiding context overflow |
Chunk size | 600 characters | The field group length of structured tables is adapted to this segment length, ensuring that field associations are not split |
Rerank result count | Top 4 entries | The number of valid daily updated data entries is small. Retaining core entries after re-ranking is sufficient to meet multi-turn dialogue needs |
The parameter values provided on this page are common recommended starting points for determining configuration. Actual values are affected by material form, 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 Mistakes
- Phenomenon: An empty result is returned after knowledge base retrieval is triggered during multi-turn dialogue, but target documents can be matched normally in the test retrieval function of the knowledge base management backend. Cause: A reasonable recalled data time range was not configured. After the full daily coke financing daily report data is updated that day, vector library index refresh delay causes some entries to not be recalled in time.
- Phenomenon: A 404 Invalid URL (POST /api/chat/completions) error is returned when calling the dialogue interface. Cause: The gateway address of the dialogue interface was not configured correctly, or the interface version does not match the currently deployed service version, resulting in an invalid request path.
- Phenomenon: After the workflow executes to the large model processing stage, the AI has generated a reply, but subsequent result transfer steps are not executed, and the dialogue ends directly. Cause: Closing markers for the output format were not explicitly specified in the prompt, causing the content generated by the large model to exceed the parsing boundary preset by the workflow, triggering abnormal workflow termination.
How to Confirm Configurations Are Correctly Set
- Access the retrieval test page of the knowledge base management backend, enter query terms related to coke financing daily reports, and check whether the number of returned documents matches the relevant configured parameters.
- Call the dialogue interface with test request parameters, check whether the returned HTTP status code meets expectations, and confirm that the interface path and version configuration are correct.
- Trigger a complete workflow execution, observe whether there is output format matching the prompt requirements in the logs, and confirm that the format constraints are correctly enforced.
- Simulate multi-turn dialogue, sequentially switch queries for coke financing daily reports of different report dates, and check whether the retained category and date information in the context is correct.
