Declaration Materials and File Review for Legality Review of Regulatory Documents: Knowledge Base Retrieval and Recall

What the Data for This Category Looks Like

Core data for this category comes from regulatory and rule libraries, higher-level law databases, departmental policy document libraries, and administrative regulatory document filing systems. Update frequency is irregular, synced in line with policy development and filing processes. Daily processed documents include regulatory document drafts, drafting explanatory notes, legality review opinions, solicited opinion feedback summaries, and filing reports. Individual document lengths vary widely, ranging from a few pages of review opinions to dozens of pages of drafts. Document fields include document numbers, issuing entities, effective dates, article content, and solicited opinion feedback. No unified standardized format template exists.

What Constraints These Characteristics Impose on Knowledge Base Retrieval and Recall

Multi-source and heterogeneous data sources require that the retrieval scope be strictly limited to compliant official datasets to avoid introducing non-authoritative references. The irregular update frequency requires the knowledge base to support incremental synchronization, ensuring retrieval results always match the latest regulatory policies. The wide range of document lengths and inconsistent formats require chunking strategies adapted to the structure of different document types, preventing key articles from being truncated or improperly split. The most time-consuming higher-level law comparison link has extremely high requirements for retrieval accuracy, requiring filtering of low-relevance results while covering all necessary reference sources to prevent missing key references for compliance review.

How to Configure Settings

Three Common Misconfigurations

• Issue: Insufficient retrieval results, only 2-3 relevant references are returned. Cause: The similarity threshold is set too high, filtering out some hierarchically relevant higher-level law articles.
• Issue: Images attached to regulatory documents uploaded to the knowledge base cannot be loaded in retrieval results. Cause: The document extended resource synchronization configuration is not enabled, or the relative paths between images and the main document were not retained during upload.
• Issue: Key articles are missing from recall results when retrieving long documents, such as thousand-page regulatory document drafts. Cause: The chunking strategy was not adjusted to adapt to the document structure, resulting in key articles being truncated and unable to be retrieved.

How to Confirm Configuration Is Complete

• Navigate to the knowledge base management page of FastGPT v4.17.0, check whether the associated dataset IDs match the predefined collectionIds.
• Initiate a simulated review retrieval, enter the core content of the article to be reviewed, and verify whether the number of returned results matches the limit setting.
• Upload a test regulatory document draft, confirm that the associated higher-level law articles are correctly recalled, and that the result similarity falls within the similarity threshold range.
• Enable retrieval log tracking, check whether the request parameters include the enabled identifiers for usingReRank and datasetSearchUsingExtensionQuery.
