What the Data for This Category Looks Like
The policy and regulatory basis data for basic telecommunications operations comes from telecommunications industry specifications released by the Ministry of Industry and Information Technology and industry regulatory authorities, internal operation systems of basic telecommunications enterprises, and telecommunications industry standard texts. Data updates follow policy revisions and regulatory requirement adjustments, with no fixed cycle. Synchronize core document updates to the knowledge base. Documents follow formal official document structure, including fields such as document number, issuing authority, effective date, clause content, and scope of application. Involved content includes communication duration, bandwidth, tariff standards, service indicators, and other related items.
What Constraints These Characteristics Impose on the Knowledge Base Retrieval and Recall Link
Long documents following formal official structure require retaining clause context during retrieval. Avoid taking content out of context after chunking. Fields such as document number and effective date require that recall results match the timeliness of the applicable scenario. Exclude expired policy documents. Professional measurement units involved must be accurately matched during retrieval. Avoid policy citation errors caused by differences in unit expressions. Data updates have no fixed cycle. Perform regular verification of knowledge base content timeliness. Prevent recall of outdated policy texts.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Matches the rigor of formal wording for basic telecommunications policies. Avoids recalling irrelevant broad content |
limit | Top 8 results | Policy documents have many clauses. Too many single recalls will exceed the context window. Ensures coverage of relevant clauses at the same time |
usingReRank | Enabled | Policy content is highly professional. Reranking filters low-relevance formal document segments from initial recalls |
datasetSearchUsingExtensionQuery | Enabled | Policy questions often contain technical terms. Extended queries supplement synonym matching and improve recall coverage |
searchMode | Exact match | Policy retrieval requires strict matching of clause content. Avoids policy citation errors caused by fuzzy recall |
collectionIds | Bind target policy knowledge base ID | Restrict retrieval scope to only datasets related to basic telecommunications policies. Prevent interference from cross-knowledge base content |
Three Common Configuration Errors
- A call to the knowledge base retrieval API returns the error
{"code":514,"statusText":"Invalid parameter or insufficient permissions"}. The cause is that the request does not properly configure a validcollectionIdsparameter, or does not bind access permissions for the corresponding knowledge base. - Recall results mix expired policy clauses. The cause is that filtering rules based on effective dates are not enabled, and the expiration status tags of policies in the knowledge base are not updated synchronously.
- The initial recall count matches the configuration, but the reranked results are empty. The cause is that after
usingReRankis enabled, the reranking model does not match valid relevant content, or thesimilaritythreshold is set too high, filtering all results.
How to Confirm Proper Configuration
- Run the built-in knowledge base search test. Enter policy questions containing technical terms such as communication tariffs and bandwidth standards. Check whether the relevance of returned results meets expectations.
- Call the retrieval API and specify a valid
collectionIdsparameter. Verify that returned results only include policy documents from the target knowledge base, with no irrelevant content mixed in. - After enabling the
usingReRankconfiguration, compare initial recall results with reranked results. Confirm that low-relevance document segments are properly filtered. - Query clearly expired policy clauses. Verify that the corresponding documents are not returned in search results. Confirm that timeliness filtering rules are working correctly.
