Policy and Regulatory Basis Q&A for Government Service Item Catalog and Service Guide Maintenance: Knowledge Base Retrieval and Recall

Policy and Regulatory Basis Q&A for Government Service Item Catalog and Service Guide Maintenance: Knowledge Base Retrieval and Recall

What data for this category includes

Core documents for this category typically include basic government service item catalogs, implementation lists, service guides, standard material directories, and flowcharts. Data is primarily sourced from the national basic government service item catalog, administrative licensing item list, power and responsibility list, and local government service item databases, with a monthly update cycle. Most documents are structured tables and standardized texts, with fixed fields including item codes, implementation levels, acceptance conditions, and application material lists. No custom unit-type fields are present.

Constraints on knowledge base retrieval and recall

Regular synchronization tasks must be configured for the knowledge base to accommodate monthly updated data sources, preventing data lag from disrupting business operations. Structured document formats require retrieval processes to balance matching accuracy for table fields and text content, avoiding field misalignment caused by fuzzy matching. Multi-source cross-level data must be separated using dataset grouping for national, provincial, municipal, and county-level catalogs, preventing mixing of item entries from different administrative levels. Fixed fields require retrieval and recall results to prioritize matching core identifiers such as item codes and implementation levels, ensuring alignment between retrieval results and business needs.

Three Common Misconfigurations

  • Symptom: Retrieval results display document download links in debug mode, but links disappear after application publishing. Cause: Document reference permissions are not enabled in the publishing configuration, or the dataset does not have public access permissions configured.
  • Symptom: Vectorization takes excessive time after uploading government service item PDF documents. Cause: Document chunk optimization is not enabled, or documents larger than the system processing limit are used.
  • Symptom: The reference limit set in the knowledge base search configuration does not match the limit set in the workflow search configuration. Cause: Failure to note that default retrieval parameter configurations differ between the application end and workflow end, and failure to manually unify configuration item values.

How to Verify Successful Configuration

  • Run a debug mode retrieval, confirm that recall results include government service item documents from the corresponding administrative level, and that matching fields meet expectations.
  • Trigger a monthly synchronization task, confirm that the knowledge base automatically pulls the latest item catalog and guide documents after the data source updates.
  • View retrieval logs, confirm that similarity scores of recall results fall within the configured range, and that sorted results have a reasonable ranking.
  • Test queries for items at different administrative levels, confirm that datasets corresponding to different collectionIds only return documents from the matching administrative level.
