What the data for this category looks like
Daily documents for this category include maintenance plans, inspection logs, defect disposal orders, road construction permits, and road damage compensation orders. Data mainly comes from highway maintenance management systems, bridge and tunnel monitoring systems, road administration inspection systems, and traffic flow monitoring data. The data update frequency is daily. Most document structures include fields such as facility number, location coordinates, disposal time, responsible entity, and disposal result. Some documents are associated with maintenance work orders and law enforcement records for specific road sections. The data dimensions cover road facility status, maintenance execution status, and the entire process of road-related affairs.
What constraints do these characteristics impose on the "citation sources and traceability" link
Data for this category comes from multiple independent business systems. Citation and traceability must associate unique identifiers from different systems to avoid cross-system data confusion. The daily update frequency requires the knowledge base synchronization mechanism to match the business data refresh rhythm, preventing the citation of outdated maintenance plans or inspection records. Documents include subdivided fields such as road section number and disposal order number. These fields must be retained during citation to accurately locate specific maintenance or law enforcement matters. Additionally, as the consequences of errors involve road safety and fund disputes, the traceability link must ensure that the cited content completely matches the original document, and core information must not be altered.
How to set the configuration
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | Documents in this category are mostly short texts such as work orders and permits. Combined with the context length requirements of party building Q&A, this range can cover complete citation fragments without exceeding the model context limit |
| Reranking | Enabled | This category of documents has many associated fields. Enabling reranking can improve the matching degree between citation fragments and the party building learning Q&A theme, avoiding interference from irrelevant maintenance data |
| Similarity threshold | 0.75–0.85 | Data in this category is closely related. A threshold that is too low will introduce irrelevant work orders, while a threshold that is too high may miss valid citations. Adjust based on actual measurement calibration |
| Single search limit | Top 6 entries | A single Q&A for this category needs to cover multiple types of documents such as maintenance and law enforcement. 6 entries can balance the recall range and citation redundancy |
responseData | Retain original document fields | Fields such as road section number and disposal order number must be included in traceability information to facilitate subsequent verification of original business records |
detail | Enable full fields | Party building learning Q&A requires clear specification of the specific document type and time of the cited content. Enabling full fields improves the traceability of the citation record |
Three common misconfigurations
- Symptom: After enabling the reranking function, the citation fragment is empty, and the number of search results is abnormal. Cause: The similarity threshold is set too high, resulting in no eligible fragments being recalled after reranking.
- Symptom: The
quoteMaxTokensetting exceeds the model context limit, causing citation fragments to be forcibly truncated. Cause: The token upper limit was not adjusted based on the average length of documents in this category, and a general configuration value was used directly. - Symptom: Traceability information does not include core business fields such as road section number and disposal order number. Cause: The full field retention configuration of
responseDatawas not enabled, and only text content was cited, making it impossible to locate the original business document.
How to confirm the configuration is correct
- Initiate a party building learning-related Q&A, check the source identification of the citation fragment in the returned results, and confirm that it includes category-specific fields such as road section number and disposal order number.
- Adjust the reranking function switch, compare the number of citations before and after enabling, and confirm that the reranking function is working properly.
- Modify the similarity threshold, verify that the number of recall results changes as expected, with no excessive recall or no recall.
- Check the knowledge base synchronization log, confirm that the daily updated business documents have been correctly included in the retrieval scope.
