What the data for this category looks like
Data sources for coal chemical industry financing daily reports include domestic coal chemical project filing and public disclosure platforms, local development and reform commission financing approval announcements, commercial bank corporate credit disclosure information, and financing statistics from professional coal industry information institutions. Updates are released before 18:00 on each working day, covering the previous day’s financing updates. Each document follows a fixed structure, including fields such as project name, affiliated coal chemical subcategory, financing amount, financing party, fund provider, financing purpose, approval date, and project location. The unit of financing amount is ten thousand yuan RMB. The approval date format is YYYY-MM-DD. Project locations are precise down to the prefecture-level city level.
What constraints these characteristics impose on the multi-turn dialogue and prompt engineering link
The data sources for coal chemical industry financing daily reports are scattered, including structured filing information and unstructured announcement content. Multi-turn dialogue must first clarify the project type, financing party, or fund provider dimension of the user’s query to avoid interference from cross-category data. The daily update requirement means that the retrieval index for multi-turn dialogue must match the update rhythm to ensure the latest financing updates are called. The fixed fields and unit requirements mean that prompt engineering must guide users to clarify the specific fields they are querying, while verifying the unit consistency of input content to avoid confusion in amount units. The multi-dimensional fields also require that the retrieval configuration balances the recall accuracy of different query dimensions to prevent irrelevant data from being included in responses.
How to set the configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | The length of a single coal chemical industry financing daily report document is mostly between 1500 and 2500 characters. Multi-turn dialogue needs to retain 3-4 rounds of context, and this interval can cover complete conversation and retrieved document content |
recall_top_k | Top 6 entries | The financing daily report data has fixed fields but multiple dimensions. Recalling 6 entries can cover the common multi-dimensional query needs of users and avoid information overload |
similarity_threshold | 0.72–0.80 | Filter low-match non-coal chemical financing data and retain daily report content strongly related to the coal chemical theme |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | The parsing time for a single financing daily report document is usually between 60 and 120 seconds. 300 seconds can cover the parsing process for batch documents |
auto_refresh_index_cron | 0 19 1-5 | Match the daily report data updated before 18:00 on working days. Automatically refresh the index every working day to ensure the retrieved content is the latest updates |
reRank_top_k | Top 3 entries | Retain the top 3 entries after reranking the recall results, focus on the most relevant financing information, and improve the response accuracy of multi-turn dialogue |
The parameter values provided on this page are all conventional recommendations used to determine the starting point for configuration. The actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to conduct actual tests on your own samples before finalizing the settings.
Three common mistakes
- Phenomenon: A 404 status code (no body) is returned when calling the multi-turn dialogue interface. Cause: The access key for the data source is not configured correctly, or the scheduled index refresh task failed to execute, resulting in missing index files.
- Phenomenon: The conversation agent can answer normally when tested in a new conversation, but a prompt "No available index model detected" pops up after refreshing the page. Cause: The deployment status of the index model has not been synchronized to the front-end configuration, or there is a spelling error in the storage path configuration of the index file.
- Phenomenon: The financing information returned by the conversation does not include the original source link. Cause: The "return retrieval source" interface configuration switch is not enabled, or the original URL field was not correctly extracted from the data source documents.
How to confirm the configuration is complete
- Manually trigger an index refresh task, check whether the task log displays the status "Index construction completed" to confirm that the data source files have been correctly loaded.
- Initiate a multi-turn dialogue, query the financing information of a known coal chemical project, and verify whether the fields and units of the returned content are consistent with the daily report documents.
- Check whether the
auto_refresh_index_cronexpression in the configuration page matches the working day update rhythm, and verify the trigger records of the scheduled task. - Enable the "return retrieval source" switch, and confirm that the returned results include the original link and document source information after initiating a conversation.
