What data for this category looks like
The policy and regulatory basis data for state-owned capital operation companies mainly comes from official documents issued by the State-owned Assets Supervision and Administration Commission of the State Council and local state-owned assets supervision institutions, as well as internal state-owned capital operation management systems, annual work reports, and regulatory compliance documents developed by the companies. The data update cycle is not fixed, and updates are synchronized with the release of new state-owned assets supervision policies, internal system revisions, or annual operation reviews. Each individual document includes fields such as document number, issuing authority, release date, main body content, and attachment descriptions. The word count of a single document ranges from several hundred characters for regulatory notices to tens of thousands of characters for operation management measures.
What constraints do these characteristics impose on the embedding models and indexing link?
The metadata fields of official and internal policy documents are clearly defined. When indexing, information such as document numbers and release dates must be associated synchronously to ensure accurate policy traceability. The wide range of document lengths, from short regulatory notices to long management measures, requires the chunking strategy to have flexibility. The non-fixed update cycle requires the indexing system to support incremental updates to avoid resource consumption from full repeated indexing. At the same time, the rigor of state-owned assets policies requires that retrieval results strictly match the original policy text, which sets higher requirements for similarity thresholds and recall rules.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapt to the typical paragraph length of state-owned capital operation policy documents, and avoid a single chunk covering multiple policy topics |
| Overlap Length | 100–150 characters | Retain contextual association between adjacent chunks, and prevent policy clauses from being incorrectly split |
| Similarity Threshold | 0.75–0.85 | Meet the rigor requirements of state-owned assets policies, filter irrelevant expressions, and focus on core policy basis |
maxToken | 8000 | Adapt to the context window limits of mainstream large models, and carry the complete content of multiple associated policy documents |
defaultToken | Calibrated based on actual testing | Adapt to the call permissions and rate limits of exclusive services, and avoid exceeding service quotas |
| Single Recall Limit | Top 3 entries | Focus on core policy basis, and avoid redundant information interfering with the accuracy of Q&A |
Three Common Misconfigurations
- After uploading policy data in bulk chunk mode, the interface continuously displays the "Indexing" status with no progress. The cause is that incremental indexing mode is not enabled, and repeated full indexing is performed on all existing policy files, resulting in task queue backlog.
- An error "This token is not authorized to use the model" is returned when calling the embedding service. The cause is that the call permissions of the exclusive service are not bound to the
defaultTokenconfiguration, and an unauthorized key is used to send the request. - Incomplete policy basis is returned during Q&A, with key regulatory clauses missing. The cause is that the chunk length setting does not match the structural characteristics of the policy documents, resulting in incorrect splitting or merging of policy clauses and broken contextual association.
How to Verify Correct Configuration
- In the FastGPT v4.17.0 environment, upload a single typical state-owned assets regulatory policy document, and check whether the indexing completion time meets expectations, with no long-term hanging status.
- Use an internal test key to call the embedding test interface, confirm that there are no permission errors, and the interface returns normal vector data.
- Input a test question, and check whether the returned policy basis includes complete clause content, with no obvious content splitting or missing.
- View the indexing task logs, confirm that indexing is only performed on newly added or modified policy files, and there are no records of full repeated indexing.
