What the Data for This Category Looks Like
Packaging and printing research report data comes primarily from public light manufacturing industry databases, monthly and quarterly reports from industry associations, annual reports of the packaging sector of listed companies, and technical white papers from printing equipment manufacturers.
There are three update schedules:
- Industry macro reports are updated quarterly
- Corporate production capacity and raw material price data is updated monthly
- Equipment process parameter data is updated irregularly alongside technological iterations
Document structures include fields such as detailed product category classification, raw material cost breakdown, production capacity utilization rate, customer group structure, environmental compliance requirements, and more. Units mostly use standard industrial measurement metrics including tons, square meters, yuan per kilogram, ten thousand yuan, and other similar units.
How These Characteristics Impact Multi-turn Dialogue and Prompt Engineering
Packaging and printing research reports have multi-field professional measurement attributes. Unit information must be retained in multi-turn dialogue context to avoid retrieval result deviations caused by unit confusion.
Different data categories have varied update schedules. Prompt engineering must clearly specify data update cycles, such as prioritizing monthly raw material price data or quarterly industry production capacity reports.
There is wide diversity in product categories. Multi-turn dialogue must gradually guide users to clarify specific packaging types to narrow the retrieval scope.
Compliance-related fields are present in the data. Retrieval instructions for compliance scenarios must be preset in prompt engineering to ensure alignment with the environmental standards users actually focus on.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Packaging and printing research reports contain multiple sets of professional data. Retaining unit and category details from multi-turn dialogue prevents information loss from context overflow |
recallTopK | Top 8–12 entries | Packaging and printing research reports have many specialized fields. Too many recalled entries overload prompts, while too few fail to cover all professional dimensions |
similarityThreshold | 0.75–0.85 | Packaging and printing professional terminology has high distinctiveness. A threshold that is too low introduces irrelevant light industry category data, while a threshold that is too high may miss accurate content |
promptTemplate | Preset packaging and printing category limiting terms, supplement detailed scenarios and data cycle requirements gradually based on user conversations | There are many packaging and printing product categories. Using multi-turn dialogue to clarify the retrieval scope prevents generalized recall |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large packaging and printing research reports contain multi-page tables and professional charts. Parsing these reports takes a long time |
enableHistorySummary | Enabled | Multi-turn dialogue accumulates multiple sets of information such as raw material prices and production capacity data. Automatic summarization reduces context redundancy |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing.
Three Common Mistakes
- Phenomenon: Calling the dialogue interface returns a 422 status code, with a prompt indicating parameter format error. Cause: The professional units and field types of packaging and printing research reports are not limited in the prompt, causing the AI-generated retrieval request to fail to meet interface verification rules.
- Phenomenon: Front-end records disappear after the dialogue window is refreshed, while complete dialogue data is retained in the background. Cause: The front-end synchronization logic for dialogue history is not correctly configured, and the background data pull interface during page loading is not bound.
- Phenomenon: AI dialogue steps are forcibly displayed to users, and intermediate retrieval processes cannot be hidden. Cause: The
showDebugInfoconfiguration item is not disabled, or the prompt does not explicitly require only returning the final question and answer results without including intermediate steps.
How to Verify Correct Configuration
- Initiate a multi-turn dialogue including corrugated packaging and raw material prices for the first half of 2024, and check whether retrieval results only match content for the specified category and time range.
- Call the dialogue interface, and check whether the returned status code meets expectations, with no parameter format error prompts.
- Refresh the dialogue page, and confirm that the front end automatically synchronizes complete dialogue records stored in the background after loading.
- Test turning off the debug information switch, and confirm that the dialogue interface only displays final question and answer content, with no intermediate retrieval steps or debug information.
