What the data for this category looks like
Data sources for this category include event tracking systems, data warehouses, CRM systems, and ticket systems. Data updates follow a daily or weekly rhythm. Regularly produced documents include usage analysis reports, event tracking plans, indicator caliber tables, and dashboard requirement forms. Data fields include customer ID, function modules, operation frequency, session duration, ticket priority, and indicator caliber descriptions. Some fields have units, such as operation counts, minutes, and ticket response time. The data structure includes two categories: structured event tracking statistics and unstructured consultation and ticket text.
What constraints these characteristics impose on the reranking and hybrid retrieval link
Data sources cover multiple systems. Hybrid retrieval must handle both structured statistics and unstructured consultation and ticket text at the same time. Cross-source field mapping must be completed in advance. Data updates occur daily or weekly. Retrieval datasets must align with the update cycle to avoid using outdated data. The accuracy of indicator caliber fields directly affects business judgments. The reranking link must prioritize matching entries with consistent calibers to reduce the risk of incorrect indicator judgments. Retrieval for customer support and pre-sales scenarios must control context length. Overly long results reduce response efficiency.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Retrieval data source scope | Event tracking systems, data warehouses, CRM systems, ticket systems | Covers all business data for this category, matches data source characteristics |
| Data update cycle | Daily update / Weekly update | Aligns with the update rhythm of category data, avoids retrieving outdated information |
| Field mapping rules | Unify customer ID, function module, and indicator caliber fields | Eliminates field differences across source data, ensures retrieval matching accuracy |
| Reranked result count | Top 3-8 entries | Calibrated through actual testing, adapts to the short context requirements of technical support and pre-sales Q&A |
| Retrieval timeout threshold | 600 seconds | Controls retrieval time consumption, ensures customer support response speed |
| Field weight configuration | Indicator caliber field weight is higher than regular text field weight | Prioritizes matching data with consistent calibers, reduces the risk of business misjudgments |
Three common configuration errors
- After configuring the reranking model, testing shows an error, but the referenced scenario runs normally. The knowledge base's "Result Reranking" function remains abnormal. The cause is failure to correctly configure the ACCESS Token for the reranking model, or the Token permissions do not cover the knowledge base retrieval scenario.
- The reranking model connectivity verification succeeds, but the knowledge base reranking function is marked as unavailable. The cause is failure to associate the reranking model with the retrieval configuration of the corresponding knowledge base, or the retrieval data source does not include the structured data fields required for reranking.
- Retrieval results do not prioritize matching entries with consistent indicator calibers. The cause is failure to set the weight priority of caliber fields, or failure to unify cross-source data field mapping rules during hybrid retrieval.
How to confirm the configuration is complete
- Enter the knowledge base configuration page of FastGPT v4.17.0, check the enabled status of the "Result Reranking" function, and confirm it is marked as normally available.
- Submit a simulated retrieval request, enter a query that includes function modules and indicator calibers, and check if the returned results are sorted to prioritize matching the preset caliber fields.
- Call the test interface of the reranking model to verify that the number and sorting of returned results match the preset reranked result count configuration.
- Check the update log of the retrieval data source to confirm that the data update cycle matches the configured update frequency.
