What This Category of Data Looks Like
Data for this category primarily comes from government information disclosure platforms, agency archive systems, document management systems, departmental business ledgers, and relevant regulations of the Government Information Disclosure Regulations. Daily processed documents include government information disclosure application forms, supplementary notice letters, third-party opinion solicitation letters, reply letters, service receipts, and administrative reconsideration response materials. Each document contains fields such as applicant information, application matters, public attribute determination, and relief path explanations. Data updates follow no fixed schedule, and occur irregularly when new applications are processed, files are archived, or policies are adjusted.
What Constraints These Data Characteristics Impose on Knowledge Base Retrieval and Recall
The data characteristics of this category impose multiple constraints on retrieval and recall. Data from multiple sources must be unifiedly integrated into the knowledge base to avoid missing cross-system historical processing materials during retrieval. Diverse document types correspond to different business fields, so retrieval must accurately match the document category for the application matter to reduce irrelevant recall results. The lack of a fixed update cycle requires the knowledge base to support irregular incremental synchronization, ensuring the latest reply and archive materials can be retrieved quickly. Individual case processing requires fast location of historical materials for a specific application, which has higher retrieval precision requirements than general scenarios. This prevents delayed replies or corrections caused by recalling incorrect materials.
How to Configure the Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Match the precise business requirements of government information application-based disclosure, and avoid recalling irrelevant public information |
limit | Top 5–7 results | Cover multiple historical materials that may be involved in a single application, while controlling context length |
searchMode | Precise matching | Prioritize matching core business fields for text related to specific application matters |
usingReRank | Enabled | Optimize the ranking of recall results to ensure the most relevant reply and supplementary materials appear first |
datasetSearchUsingExtensionQuery | Enabled | Convert colloquial expressions of applications into retrieval terms that comply with business standards |
collectionIds | Bind to actual government affairs office datasets | Limit the retrieval scope to only documents related to this department’s application-based disclosure work |

Three Common Misconfigurations
- Phenomenon: Knowledge base retrieval results show document download links in debug mode, but the links disappear after the application is published. Cause: Document external link permission is not enabled in the publishing configuration, or the bound dataset does not have public download permission enabled.
- Phenomenon: Vectorization takes too long when uploading a single PDF document larger than 500 MB. Cause: Large-volume documents are not split, resulting in excessive single-batch processing data volume.
- Phenomenon: The reference upper limit of the knowledge base search configuration in the application end is inconsistent with the search configuration upper limit in the workflow. Cause: The parameter values of the two scenarios are not manually adjusted uniformly, and the default configurations differ.
How to Verify Proper Configuration
- Enter debug mode to initiate a simulated government information application-based disclosure retrieval, and check whether the number and sorting of recall results meet business expectations.
- Check whether the parameter values of configuration items match business requirements, and confirm that parameters such as
similarityandlimithave been set as required. - Verify that after the application is published, the business information of relevant documents is normally displayed in the retrieval results, with no abnormal missing content.
- Initiate an incremental synchronization operation to confirm that newly uploaded government information application-based disclosure documents can be normally retrieved.
