Data Profile for This Category
This category’s data originates from the National Primary and Secondary Student Academic Status Information Management System, local student enrollment platforms, household registration and property data, and school academic affairs systems. Updates occur daily. Commonly processed documents include enrollment application forms, student academic status information forms, transfer applications, enrollment plans, admission rosters, and student academic status change approval forms. Data fields focus on student identity, household registration and property association information, enrollment eligibility, and student academic status change approval content. Single record size falls between hundreds and thousands of characters. No additional non-business-related statistical fields are included.
Constraints Imposed on Vector Models and Indexing
Daily data updates require indexes to support incremental synchronization. This avoids resource consumption and delays caused by full index rebuilding. Data includes unique identity identification fields. Indexes must associate these fields to enable precise matching. This prevents semantic confusion between different students’ academic status information. Most documents are structured form content. Vector models must support combined retrieval of short text and associated fields. This avoids interference from irrelevant fields during semantic vector generation. Format differences across multiple data sources require unified field mapping rules during index construction. This ensures vector consistency across data from different sources.
Configuration Settings
The following configurations align with the interface and parameter logic of FastGPT v4.17.0:
| Configuration Item | Recommended Range | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Matches the length of single-section form content in enrollment application forms and student academic status change approval forms. Prevents semantic breaks caused by cross-field cutting |
| Overlap Length | 100–150 characters | Covers associated fields across chunks. Ensures key information such as student ID numbers and household registration addresses is fully included in adjacent chunks |
| Similarity Threshold | 0.75–0.85 | Adapts to semantic matching accuracy for structured identity data. Prevents accidental matching of different students’ academic status information |
| Single Recap Limit | Top 10 entries | Controls the number of returned results. Avoids excessive redundant academic status data interfering with final document drafting logic |
maxToken | 4000 token | Adapts to context length for bulk documents such as enrollment plans and admission rosters. Ensures full loading of key approval information |
defaultToken | 200 token | Sets the default output token limit for single chunks. Balances semantic completeness and retrieval efficiency |
Three Common Misconfigurations
- Multiple duplicate student academic status entries appear in search results. This occurs when unique identity identification fields are not associated in the index. Identical semantic content across different chunks is recalled repeatedly.
- Incremental synchronization tasks frequently trigger timeouts. This occurs when incremental update rules are not configured. Daily full synchronization of large volumes of historical academic status data exceeds system processing limits.
- Missing household registration address fields appear in generated documents. This occurs when chunk length is set too short. Form content containing complete household registration addresses is split into multiple chunks. Key information is not recalled.
How to Verify Proper Configuration
- Upload a single enrollment application form. View the chunk preview interface. Confirm that key fields such as student ID numbers and household registration addresses are not split across chunks.
- Initiate a search targeting a specific student’s academic status ID number. Check that returned results only include data related to that student. No duplicate entries are present.
- Run the daily incremental synchronization task. View synchronization logs. Confirm that only newly added or modified academic status data from the current day is updated. No full index rebuilding is triggered.
- Test search results across different similarity threshold values. Adjust thresholds to match the matching accuracy required for the business scenario.
