Multi-turn Dialogue and Prompt Engineering for

What the data for this category looks like

Data for optoelectronics industry intelligent due diligence reports primarily comes from industry association monthly briefings, listed companies periodic reports, customs import and export trade data, and patent retrieval databases. Monthly industry data updates every 7 business days. Corporate operating data updates concurrently with quarterly reports. Patent data updates in real time.

Document structure is divided into four sections: industry trends, supply chain details, core product parameters, and compliance information. Fields include product model, shipment volume (unit: ten thousand pieces), raw material cost (unit: yuan per piece), patent application date, and others. The length of a single complete report varies widely. It is recommended to calculate based on internal samples or conduct actual testing before finalizing values.

Constraints on multi-turn dialogue and prompt engineering

Dispersed data sources and inconsistent update cycles require multi-turn dialogue to first confirm the required data update cycle and source type, to avoid calling outdated or irrelevant information.

Multiple document modules and diverse field units require prompts to explicitly specify the called module scope and unit alignment rules, to prevent unit confusion in analysis results.

Longer single report lengths require multi-turn dialogue to retain sufficient context information, ensuring that follow-up questions can be linked to previous categories and parameters.

Real-time updated patent data requires prompts to configure real-time retrieval trigger conditions, to ensure the timeliness of compliance information.

How to set configurations

Configuration Item	Recommended Value	Rationale
`maxContext`	`8000–12000 characters`	Single optoelectronics due diligence report length typically ranges from 5000 to 8000 characters; retaining sufficient context enables handling multi-turn consecutive follow-up questions
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Some supply chain detail documents include large volumes of tabular data, requiring extended parsing timeout periods
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Monthly briefing collections from industry associations have large file sizes, requiring support for large-capacity file uploads
`Recall count`	`Top 6 results`	Core fields of optoelectronics due diligence reports are concentrated in the top few recall results, covering most analysis requirements
`Similarity threshold`	`0.75`	Optoelectronic product models often have similar naming conventions, requiring filtering of low-relevance search results
`Chunk size`	`1500 characters`	Clear module boundaries exist in due diligence reports; segmenting documents facilitates precise matching of user specific questions

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to conduct actual testing on internal samples before finalizing settings.

Three common mistakes

Issue: Unit confusion occurs during multi-turn consecutive follow-up questions, such as mixing the ten thousand pieces unit for panel shipment volume with the ten thousand sheets unit for lens shipment volume. Cause: Unit alignment for the current conversation is not enforced in the prompt, leading to failure to retain unit information in context.
Issue: Insufficient number of results are returned when calling due diligence reports, with a 400 Bad Request status code returned in the interface. Cause: The Recall count configuration value is set too low, failing to cover core analysis fields of due diligence reports.
Issue: Automated script executions triggered via dialogue fail to correctly read due diligence report files from the specified directory. Cause: The relative path of the file path and naming rules for target files are not explicitly specified in the prompt, corresponding to a configuration oversight in integrated automated operations.

How to verify proper configuration

Upload a single due diligence file with a volume consistent with industry report standards, confirm no errors occur during the upload process, and verify that the UPLOAD_FILE_MAX_SIZE configuration is compatible.
Initiate two consecutive follow-up questions: first ask for the shipment volume of a specific product category, then ask for the corresponding unit cost, confirm no unit confusion appears during the conversation, and verify the rationality of context retention and unit alignment configurations.
Adjust the Recall count and Similarity threshold values, verify that the relevance and quantity of returned results meet expectations, and confirm the effectiveness of retrieval-related configurations.
Trigger the conversation opening shortcut button, confirm that the loaded guide text clearly points to the analysis direction of optoelectronics due diligence reports, and verify the binding configuration of preset prompts.

Question material comes from public community discussions. Configuration values are common starting points and should be measured against your own samples. Verified on 2026-09-14.
