What This Category of Data Looks Like
Grain reserve declaration materials and file review data comes from three main sources: internal business systems of grain administrative departments, daily operation logs of reserve granaries, and superior reserve plan documents. Data updates trigger along business workflow nodes:
- Archive content updates when a declaration is submitted
- Inventory and quality inspection data updates when reserve grain is rotated or inventory is adjusted
A single declaration material is typically a multi-page PDF or structured table. A file is an archive package of multiple materials. Core fields include reserve grain category, storage bin number, inbound/outbound batch number, and quality inspection parameter items. Corresponding units include tons, bin numbers, batch numbers, and similar identifiers.
Constraints for Multi-turn Dialogue and Prompt Engineering
Dispersed data sources that update with business nodes require multi-turn dialogue to associate with the current business batch, to avoid mixing data across batches. Mixed-format document structures require prompts to separate extraction rules for structured fields and unstructured text, preventing misalignment of extracted fields. Specific field unit requirements demand mandatory compliance checks in prompts, to avoid misuse between tons and kilograms. Archive package-style files require dialogue to first specify the file ID before loading corresponding data, to prevent loading excessive irrelevant content and causing context overflow.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Bind to the current declaration batch ID | Ensure dialogue context associates with a specific file, avoid cross-batch confusion |
messages | Retain the most recent 20 dialogue turns | Control context length, prevent processing timeouts |
| Question Optimization | Enabled | For multi-field validation of declaration materials, first optimize the user's review questions to clarify review dimensions |
| Maximum Context | 8000–12000 characters | Adapt to the text length of multiple materials in a single file |
| Single Search Limit | Top 3 results | Relevant fields of declaration materials are concentrated; excessive recall will interfere with review judgments |
chatId | Bind to the business system file number | Ensure each dialogue corresponds to a unique declaration file, comply with business permission isolation requirements |
Three Common Misconfigurations
- Phenomenon: An error occurs when calling the associated knowledge base in dialogue, with no error displayed in the preview interface. Cause:
variablesis not bound to the current declaration batch ID, causing the knowledge base-recalled file data to not match the current dialogue's business node. - Phenomenon: After uploading a reserve grain quality inspection report PDF, the system fails to extract structured fields. Cause: Appropriate chunking rules are not configured for structured tables, or chunk length is set too short, truncating continuous field content of the table.
- Phenomenon: After switching declaration batches in multi-turn dialogue, field confusion appears in review results. Cause:
chatIdis not bound to the business system's file number, causing the context to retain old batch review data.
How to Verify Successful Configuration
- Initiate a review dialogue for a single declaration file, check that the bound
variablesbatch ID matches the file number in the business system. - Upload multiple mixed-format declaration materials, confirm that the recalled text covers core fields, and verify that the single search limit setting adapts to the recall needs of the current scenario.
- Initiate multiple consecutive rounds of review questions, check that the context retains the current batch's review records and does not mix information from other batches.
- Test uploading structured table-style quality inspection reports, confirm that the system correctly extracts preset field items.
