Knowledge Base Retrieval and Recall for Aquaculture

What the data for this category looks like

Data sources include financing monitoring reports for breeding entities from local aquaculture industry associations, breeding credit filing records from county-level fishery administration departments, agricultural loan ledgers from partner banks, and supporting financing records from feed ingredient trading. Updates occur daily; same-day data is compiled by the next morning. Each daily report includes fixed fields: statistical date, breeding category, full and abbreviated names of financing entities, financing amount (unit: yuan), financing purpose, credit granting institution, approval time limit (unit: days). Supplementary documents may include breeding area (unit: mu) and quarterly production forecast data.

Constraints on Knowledge Base Retrieval and Recall

Multi-source data format differences require unified field mapping during preprocessing to avoid field matching confusion during retrieval. The daily update frequency requires incremental indexing configuration; otherwise, retrieval delays will occur. Fields include numeric content with units such as amount and area, so enable numeric matching rules to prevent recall errors caused by missing units. Financing entities have abbreviated and full name variants, so configure entity recognition rules to ensure the same entity with different expressions is associated during retrieval.

Recommended Configuration Settings

Configuration Item	Recommended Value	Rationale
`maxChunkSize`	600–1000 characters	Aquaculture financing daily reports have clear fields and moderate single financing record lengths. Short chunk sizes avoid cross-field matching interference and improve retrieval accuracy for single financing information.
`topK`	Top 6–8 entries	The number of daily aquaculture financing projects is limited. Too many recalled entries increase context redundancy, while too few may miss valid financing information.
`similarityThreshold`	0.72–0.80	Financing-related keywords such as "breeding loan" and "credit granting" have high recognizability. This threshold filters low-relevance results while retaining valid matching content.
`incrementalUpdateInterval`	1 hour	Daily reports are updated daily. A short interval ensures newly added financing information of the day is indexed in time to avoid retrieval delays.
`ragUploadMaxSize`	100 MB	Single aquaculture financing daily report files are small in size. This limit prevents upload timeouts for large files while adapting to batch upload requirements for multi-source documents.
`parseTimeout`	300 seconds	Daily reports in multi-source formats require additional format alignment processing. This duration ensures complex documents complete parsing.

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.

Three Common Configuration Mistakes

Phenomenon: Newly added aquaculture financing daily report content in the knowledge base returns no search results, and the console returns an empty recall list. Cause: The knowledge base incremental update switch is not enabled, or incrementalUpdateInterval is set too long, so newly uploaded daily report files of the day are not synchronized.
Phenomenon: After upgrading to version 4.14.3, uploading financing daily report files stored in S3 fails, and the interface returns an "upload timeout" error. Cause: The ragUploadMaxSize parameter is not adjusted to adapt to S3 storage concurrency limits, or the access key permissions for the S3 configuration are insufficient.
Phenomenon: Non-aquaculture financing entries are mixed in search results, with field matching confusion. Cause: Field-level retrieval rules are not configured, or similarityThreshold is set too low, causing irrelevant text to be recalled.

How to Verify Correct Configuration

Upload a test aquaculture financing daily report sample with marked fields, wait for the incrementalUpdateInterval duration, then enter "XX cooperative financing" in the search box, and check whether the recall results include field information such as the financing amount and breeding category in the sample.
Enter the update log page of the knowledge base management interface, confirm that the newly added daily report files of the day have been indexed, and the status shows "completed".
Adjust the similarityThreshold to 0.75, search for irrelevant keywords such as "real estate financing", confirm that no irrelevant results are recalled, and verify that the threshold setting is reasonable.
Test numeric field retrieval, enter "breeding area 50mu", confirm that only financing records containing this value and unit are recalled.
