Multi-turn Dialogue and Prompt Engineering for Property

What the data for this category looks like

Data sources for property management financing daily reports include internal financing management systems of property enterprises, push data from cooperative financial institutions, and project financing filing public notices from local housing management departments. Data updates follow a T+1 schedule each day, with full financing records for the previous day released. Each document is organized using individual project financing as the unit. Each record includes project unique identifier, project name, project address, full financing subject name, financing amount, financing start date, financing expiration date, fund disbursement node, and corresponding property type. The number of fields varies widely across different institutions. It is recommended to count or test based on your own samples before finalizing the field set. Financing amount is measured in ten thousand yuan. Financing term uses natural days as the unit. Fund disbursement node is a text field containing specific time points.

Constraints on multi-turn dialogue and prompt engineering

First, data is split into individual financing records with unique identifiers. Multi-turn dialogue must retain the project unique identifier in context to avoid confusion across projects. Second, the daily update frequency requires prompts to explicitly specify that the latest T+1 data source be prioritized. Expired data must not be used. Third, the fixed field structure requires prompts to explicitly list the fields to be extracted. This prevents large language models from missing key information. Fourth, single documents contain dozens of records. Recall configurations must balance information completeness and context window usage to prevent excessive redundant information from interfering with dialogue logic.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`recall count`	6-8	The number of entries in a single property management financing daily report document is moderate. An excessive number will exceed the context window, while an insufficient number will miss key project information
`similarity threshold`	0.72-0.80	The project unique identifier is the core matching field for financing daily reports. A higher threshold avoids recalling records from unrelated projects
`maxContext`	8000-12000 characters	Multi-turn dialogue requires retaining project unique identifiers, user follow-up question history and other information. A longer context window helps prevent context loss
`segment length`	1000-1500 characters	Single financing records contain multiple fields. Segment length is matched to the information volume of a single record to avoid splitting associated information for the same project
`PARSE_FILE_TIMEOUT_SECONDS`	300 seconds	Property management financing daily reports contain dozens of project records, which take a long time to parse and index. Reserve sufficient time to complete processing
`reference content template`	Display after grouping by project unique identifier	Property management financing daily reports require information to be integrated by project. Grouped display improves the readability of information in multi-turn dialogue

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.

Three Common Mistakes

The symptom is that financing information returned by the dialogue does not include the specified fund disbursement node field. The cause is that the prompt does not explicitly list the fields to be extracted, causing the large language model to only return default fields.
The symptom is that after calling the interface to connect the knowledge base, the dialogue cannot recall financing daily report data updated on the current day. The cause is that the automatic update trigger rule of the knowledge base is not configured, or the update delay is not set to T+1 synchronization.
The symptom is that after configuring the knowledge base reference template, the content returned by the dialogue still does not display grouped by project. The cause is that the scope of action of the prompt template and the knowledge base reference template is confused, and the grouping rule is not specified in the reference template.

How to Confirm Configuration is Complete

Initiate a query for financing information of a single project. Check whether the returned result includes all preset fields, and adjust the similarity threshold until the matching accuracy meets requirements.
Initiate three consecutive follow-up questions about different projects. Check whether the dialogue context retains the unique identifier of each project, and adjust maxContext until no context loss occurs.
Upload a test version of the financing daily report document. Check whether the number of parsed fragments matches the number of entries in the document, and adjust the segment length until the fragment logic meets expectations.
View the knowledge base update log. Confirm that the daily T+1 automatic update task has been triggered normally, and adjust PARSE_FILE_TIMEOUT_SECONDS to ensure parsing is completed.
