What this category of data looks like
The data sources for urban public transport party building learning Q&A are party building files archived by the enterprise's party and mass work department, monthly learning plans, party member activity ledgers, and standardized party lesson courseware. The update schedule is to synchronize archived content within 1 to 3 working days after new party building policies are released, and update standardized party lesson texts every quarter. The document structure is mainly single independent files, including title, issuing unit, release date, and main body content. Some party lesson records with speech transcription are included, with fields including document ID, classification tags, file format, and associated party member learning activity number.
What Constraints These Characteristics Bring to Multi-turn Dialogue and Prompt Engineering
The data sources are limited to internal party building content of the public transport system, which requires that the knowledge boundary of multi-turn dialogue strictly matches the preset scope to avoid introducing external irrelevant information. Differences in update frequencies require that prompt engineering must regularly synchronize the latest archived policy documents, while multi-turn dialogue must support recalling learning content from corresponding periods based on time ranges. The classification tags and activity number fields of documents can be used to limit the recall dimension of multi-turn dialogue, avoiding interference from cross-category content. Speech-transcribed party lesson texts have format errors, so prompt engineering must have the ability to correct colloquial transcribed content to ensure accurate recognition of historical content in multi-turn dialogue.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum context length | 8000–12000 characters | Matches the average length of single party building documents for public transport, avoids truncating core policy content |
| Session context retention duration | 7 days | Adapts to the monthly learning cycle of public transport party members, retains multi-turn dialogue memory within a single month |
variables | Preset "public transport party building exclusive" and "urban public transport system" variables | Limits the knowledge scope of dialogue, avoids calling external irrelevant content |
messages | Retain the most recent 20 dialogues | Controls the amount of context data per single request, reduces response latency |
| Question optimization | Enabled | Corrects colloquial party-building related expressions in party members' questions, improves content recall accuracy |
chatId | Enable persistent storage | Ensures that the session identifier for multi-turn dialogue can be retained across restarts and across nodes |

Three Common Misconfigurations
- Symptom: Historical conversations older than 7 days cannot be recalled normally, and the session list shows as empty on the interface. Cause: The persistent storage policy for
chatIdis not configured, and only local temporary session caching is retained by default. - Symptom: Single-turn dialogue response latency exceeds 10 seconds, and some requests trigger timeout errors. Cause: The number of historical messages retained in
messagesis not limited, and too much context data is loaded for each request. - Symptom: The save duration of dialogue logs cannot be adjusted, or the corresponding configuration parameter cannot be found. Cause: System files unrelated to dialogue log storage were modified accidentally, and preset variables for the log retention cycle were not configured via
variables.
How to Verify Successful Configuration
- Initiate a multi-turn question that includes historical context, and verify that the system can associate previously mentioned party building learning content. For example, after referencing "the integrity construction document learned last week", the system should recall the corresponding archived document.
- Initiate a single-turn test question, check the response latency, and confirm that frequent timeouts exceeding 10 seconds do not occur.
- Enter the system variable configuration interface, check whether the "public transport party building exclusive" knowledge scope variable is preset in
variables, and ensure that dialogue does not exceed the limited content. - View the dialogue log list, confirm that sessions older than 7 days can still be viewed normally, and verify that the persistent storage configuration for
chatIdtakes effect.
