What the Data for This Category Looks Like
Coal chemical industry policy and regulatory basis data comes from modern coal chemical industry policies released by the National Energy Administration and the National Development and Reform Commission, internal compliance manuals of central and state-owned enterprises, and local coal chemical industry planning documents. Updates trigger when new policies are released. Regular maintenance follows a quarterly synchronization cycle. Each document includes fields such as document number, issuing authority, release date, applicable scenarios, clause details, and penalty notes. Document numbers follow the format [Abbreviated Issuing Authority] 〔XXXX〕 XX Number. Release dates use the YYYY-MM-DD format. Clauses are marked with "Article X".
Constraints Imposed on Multi-turn Dialogue and Prompt Engineering
Single coal chemical policy documents are relatively long. Multi-turn dialogue must retain previously cited clause content. The context length for multi-turn dialogue must be adapted for long text scenarios. Policy update frequency is high. The knowledge base synchronization cycle must match the policy release pace. This avoids retrieving outdated content. There are many specialized terms in coal chemical policies. Prompts must clearly restrict the retrieval scope to coal chemical-related policies. Prompts must also require returning specific fields such as document number and release date. Coal chemical policies vary across different regions. Corresponding documents must be accurately matched using regional parameters provided by user input.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Maximum Context Length | 8000–12000 characters | Single coal chemical policy documents are relatively long on average. Multi-turn dialogue needs to retain previously cited clause content |
| Question Optimization Switch | Enabled | Coal chemical policies contain specialized terms. Optimization improves retrieval matching accuracy |
| Single Recall Count | Top 8–12 entries | Policy documents are categorized by document number. Relevant clauses from different issuing authorities need to be covered |
| Conversation Timeout Setting | 600 seconds | Long text retrieval and multi-turn interaction require sufficient time. This avoids mid-interruption |
| Variable Binding Configuration | Bind variables field | User-specified parameters such as project region and industry type must be passed. This ensures accurate matching of corresponding policies |
| Conversation ID Management | Bind chatId field | Retain context association for multi-turn dialogue. Avoid confusion across sessions |
| Message Context Configuration | Concatenate in messages field order | Strictly follow dialogue history order. This ensures logical consistency of multi-turn interaction |
Three Common Misconfigurations
- Calling the
api/v1/chat/completionsinterface without returning coal chemical policy results with specified tags. Phenomenon: Interface returns results that do not match the preset provincial coal chemical policy tags. Cause: No knowledge base tag parameter was passed in thevariablesfield. - Unable to associate and retrieve uploaded coal chemical policy PDF attachments during multi-turn dialogue. Phenomenon: The system prompts that relevant data cannot be found when attachment content is mentioned in the conversation. Cause: Automatic attachment chunking configuration was not enabled. Long text was not fully indexed as a result.
- Empty results returned after consecutive multi-turn dialogue interactions. Phenomenon: Responses are empty for conversations on the 4th turn or later. Cause: Maximum context length was set too small. Previously cited policy clause information was not retained.
How to Confirm Configuration Is Correct
- When calling the
api/v1/chat/completionsinterface, check if thevariablesfield includes parameters such as knowledge base tags and project region. Confirm that the parameter format meets the requirements of FastGPT v4.17.0. - Enable test dialogue. Upload a coal chemical policy attachment. Input "Please extract the document number of this file". Verify whether the system returns the correct document number content.
- Enable multi-turn dialogue. Input 3 consecutive questions about different coal chemical policies. Verify whether the system retains the context association from previous conversations.
- View the knowledge base synchronization log. Confirm that the update frequency of coal chemical policy documents matches the configured synchronization cycle.
