What the data for this category looks like
Data for declaration materials and case review in basic telecommunications operations originates from internal business systems, including user declaration work orders, qualification document upload libraries, and billing approval circulation archives. Updates occur either per individual declaration batch or via daily synchronization. Document structures include structured form fields (such as the declaring unit’s unified social credit code, project number), unstructured scanned documents (such as business licenses, PDF networking plans), and approval circulation logs. Fields contain unique identifiers, approval status, and circulation nodes. Common units are copies, entries, and times.
What constraints these characteristics impose on the citation sources and traceability workflow
Unique identifier fields in structured forms require traceability to be bound to precise project numbers, to avoid mixing different declaration projects. Unstructured scanned documents must first undergo OCR recognition and be linked to structured fields to enable complete traceability. Frequently updated business data requires knowledge base synchronization cycles of no more than 24 hours, to ensure cited content reflects the latest approval status. Multi-stage approval circulation logs require retention of contextual associations, otherwise traceability cannot reflect the complete review process.
Configuration Settings
| Configuration Item | Recommended Setting Range | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Declaration materials for basic telecommunications operations include long-text networking plans and approval logs. This length preserves complete contextual information. |
| Overlap Length | 150–200 characters | Prevents cross-chunk approval circulation records from being split, ensuring traceability can link consecutive review stages. |
quoteMaxToken | 2000–3000 tokens | Case review requires linking multiple segments of approval records and qualification documents. This range covers full citation needs. |
| Single Recalled Entries | Top 6–8 entries | A single basic telecommunications declaration is associated with a limited number of documents. This range avoids interference from redundant information. |
detail | Enabled | Requires displaying specific fields and source locations of traceable documents, to meet traceability requirements for case review. |
responseData | Enabled | Requires returning unique identifiers of traceable documents, to support external systems in linking to original case files. |
Three Common Configuration Errors
- Phenomenon: Application results generated via external API calls have no citation source fields. Cause: Knowledge base external call permissions were not configured in FastGPT v4.17.0, limiting retrieval scope to only local private libraries.
- Phenomenon: After adjusting
quoteMaxTokento above 2000, the large language model does not cite any retrieved content. Cause: The total context length exceeds the support limit of the currently bound model, resulting in automatic truncation of citation segments. - Phenomenon: Specific approval circulation records are missing from traceability results. Cause: Chunk length was set too small, causing consecutive approval logs to be split and lose their associated relationships.
How to Verify Configuration is Set Correctly
- Navigate to the knowledge base management page in FastGPT v4.17.0, and check if chunk length and overlap length configurations match preset values.
- Initiate a simulated declaration review query, and check if the system logs include the actual used value of
quoteMaxTokenand retrieved document segments. - Call the external API to obtain generation results, and confirm that the
responseDatafield contains unique identifiers and source locations of traceable documents. - Test adjusting the value of
quoteMaxToken, and observe whether the number of cited segments in the generation result changes with the configuration.
