What This Category of Data Looks Like
Data for policy and regulatory basis of telecommunications engineering construction mainly comes from industry specifications, project approval documents and compliance rules issued by the Ministry of Industry and Information Technology, the Ministry of Housing and Urban-Rural Development, and provincial and municipal communications administrations. Data updates follow industry standard revisions and local policy releases, usually on a quarterly or annual basis. Individual documents typically include fields such as release number, effective date, applicable construction scenarios, and core compliance clauses. Some documents also include supporting content such as project budgets and acceptance standards.
What Constraints Do These Characteristics Impose on the Knowledge Base Retrieval and Recall Link
The multi-source and scenario-based nature of telecommunications engineering construction policy data imposes three core constraints on retrieval and recall. First, the data covers national industry standards and local implementation rules, so joint retrieval across multiple datasets must be supported. Second, each document is marked with an effective date and applicable region, so retrieval must filter valid results by time and geographic dimensions. Third, clauses are split by construction scenarios, so matching must target specific keywords such as base station deployment and pipeline erection to avoid retrieving irrelevant compliance requirements.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity | 0.72–0.80 | Telecommunications engineering policy clauses have high professional specificity, so low-relevance results must be filtered. This range balances retrieval coverage and precision |
limit | Top 8 results | Individual policy documents have lengthy content. Too many retrieved results will exceed context limits. 8 results cover core compliance basis |
searchMode | Precise matching | Policy clauses require strict keyword matching. Fuzzy matching may introduce irrelevant industry specifications. Precise mode improves result relevance |
usingReRank | Enabled | Semantic similarity for professional documents can be disrupted by technical terms. Reranking revises retrieval rankings based on contextual semantics |
datasetSearchUsingExtensionQuery | Enabled | Policy terms include industry abbreviations such as 5G base station and FTTH. Extended queries supplement synonym-based retrieval |
collectionIds | Bind corresponding datasets by construction scenario | Different construction scenarios correspond to different policy sets. Binding specified datasets reduces irrelevant retrieval |
Three Common Misconfigurations
- Phenomenon: Knowledge base calls return parameter format errors, with an invalid
datasetIdfield prompt. Cause: The wrong variable reference format was used. The generic template[{datasetId: xxx}]was used for dataset binding, and required datasets were not configured per platform requirements. - Phenomenon: The knowledge base remains in the indexing state for an extended period after upload. Cause: Telecommunications engineering policy documents are lengthy and include professional technical tables. Indexing requires complex format conversion, which exceeds the default indexing timeout threshold.
- Phenomenon: Knowledge base records cannot be filtered based on enterprise identity. Cause: The permission identifier feature was not enabled in dataset configuration, and enterprise-specific identifier fields were not added to knowledge base entries.
How to Verify Proper Configuration
- Submit a test retrieval request with a specific construction scenario keyword such as "5G base station acceptance standards", and verify that the effective date and applicable region of returned results match the retrieval conditions.
- Review the ranking of retrieval results, and confirm that the reranked results match the semantic relevance of technical terms as expected.
- Check the dataset binding configuration, and confirm that policy document sets are associated by construction scenario, with no retrieval across irrelevant datasets.
- Test variable reference and permission filtering, and confirm that specified identifiers correctly filter corresponding knowledge base entries.
