What This Category of Data Looks Like
Telecommunications engineering construction document data mainly comes from internal documents including project approval documents, construction drawings, on-site supervision logs, and completion acceptance reports. Data update rhythm follows project milestones: project approval and design data are synchronized before construction starts, on-site logs are updated weekly during the construction phase, and final reports are archived after acceptance is completed. Document structures include fields such as unique project number, construction section division, communication equipment parameters, and acceptance standards. Units include professional engineering units such as Mbps, days, and square meters. The length of a single document ranges from several pages to dozens of pages, and some long documents contain continuous professional construction plan paragraphs.
Constraints Imposed on Citation Sources and Traceability by These Characteristics
Professional fields and unit requirements for telecommunications engineering documents require traceability results to accurately match specific project parameters. Therefore, the search scope must be limited to knowledge base documents of the current project to avoid confusion of cross-project data. The long professional content of documents requires citations to retain complete semantics, and the context of key parameters must not be truncated, otherwise traceability results will fail to verify the correctness of engineering data. The data update feature that follows project milestones requires that traceability configuration supports triggering knowledge base synchronization by project batches; fixed-cycle refresh cannot adapt to temporarily added project data. At the same time, compliance requirements stipulate that traceability results must mark the specific type and paragraph position of the source document, ensuring that every citation can be traced back to the original engineering document.
How to Set the Configuration
The following configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum Context | 1200–1500 characters | Covers common professional construction paragraphs in telecommunications engineering documents, avoiding truncation of content containing core parameters |
| Single Search Limit | Top 6 results | Matches the multi-field, multi-milestone characteristics of telecommunications engineering documents, filtering the most relevant project documents |
| Reranking | Enabled | Prioritizes sources with higher matching degrees for core fields such as communication equipment parameters and project numbers |
quoteMaxToken | 800 token | Controls the length of a single citation, adapting to the reasonable display range of professional paragraphs |
responseData | With source document identifier | Clearly marks the document type, project number and paragraph position of the source, meeting compliance traceability requirements |
detail | Enabled | Displays the context of the cited paragraph, facilitating verification of the accuracy of engineering data |
Three Common Mistakes
- Phenomenon: The response does not include telecommunications engineering document content from the local knowledge base, but the citation list shows that relevant documents were matched. Cause: The source content output configuration corresponding to
responseDatais not enabled, and only the citation identifier is returned without synchronizing professional parameter content from the main text. - Phenomenon: The returned citation source does not mark the specific communication project number or construction section. Cause: The search scope is not configured to filter by document fields, resulting in matching historical documents from unrelated projects.
- Phenomenon: Citation content has sentence break errors, and key engineering parameters are truncated. Cause: The value of
quoteMaxTokenis too small, truncating complete professional paragraphs containing core parameters.
How to Verify the Configuration Is Correct
- Upload a telecommunications engineering completion acceptance report containing base station numbers and transmission bandwidth parameters, initiate a query that includes these parameters, and check whether the response contains the corresponding parameters and the citation source marks the document name and paragraph position.
- View the citation list, confirm that each citation corresponds to the uploaded local knowledge base document, with no external unrelated sources.
- Adjust the value of
quoteMaxToken, observe the length change of the cited content, and verify that the configuration takes effect. - Test a general engineering question that is not present in the knowledge base, confirm that the response does not incorrectly associate the current project's telecommunications engineering document content.
