What data looks like for this category
Intelligent due diligence report data in the publishing industry comes primarily from topic filing archives, copyright registration certificates, sample book archive files, industry compliance audit records, and distribution ledgers of publishing units. Data update rhythm is triggered by publishing workflow nodes: basic information is updated when a topic is approved, print and distribution data is added after sample books are delivered, and full archive records are updated during annual compliance reviews. Document structures include fields such as topic name, 13-digit ISBN number, author identity information, copyright validity period, print volume, distribution channel list, and compliance audit opinions. Each field follows fixed format units and identification rules.
What constraints these characteristics impose on knowledge base retrieval and recall
The multi-node update feature of publishing due diligence reports requires the knowledge base to support on-demand incremental synchronization, adapting to non-fixed update nodes such as topic approval and sample book delivery. Document structures with long text and unique identifier fields like ISBN numbers and author information require the retrieval link to support both semantic recall and field-level precise matching, preventing identifier matching failures caused by relying solely on semantic recall. Dispersed compliance-related information requires the recall volume to cover enough relevant fragments, while threshold filtering of redundant results is needed to ensure returned content is highly relevant to due diligence requirements.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Segment Length | 1000–1500 characters | Publishing due diligence reports contain long texts such as copyright clauses and distribution data. Too long segments will lose contextual association, while too short segments will damage the integrity of compliance clauses |
Recall Count | Top 8–12 entries | Compliance-related information in due diligence reports is scattered across different document fragments. A sufficient recall volume is needed to cover relevant compliance requirements, while avoiding excessive redundant results |
Similarity Threshold | 0.72–0.78 | Distinguish similar expressions in compliance audit opinions, avoid mistakenly recalling irrelevant publishing topic data, while retaining matching accuracy for core compliance content |
Field-level Retrieval Switch | Enabled | Precisely match unique identifier fields such as ISBN numbers and author names, improving retrieval accuracy for specific publishing projects |
Incremental Update Trigger Rule | Triggered by topic approval / sample book delivery events | Adapt to the non-fixed update rhythm of publishing due diligence reports, avoiding ineffective full synchronization operations |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Publishing due diligence report documents have relatively long lengths, so sufficient parsing time must be reserved to complete complete content splitting and index construction |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, 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: An error prompt indicating no selected knowledge base is returned during formal calls, but retrieval results are normal in the debug preview. Cause: The knowledge base binding configuration in the production environment was not synchronized to the publishing node, or the environment variable
KB_DEFAULT_ENABLEDwas not correctly configured to the enabled state. - Phenomenon: The knowledge base output answer references incorrect publishing due diligence report files. Cause: The field-level retrieval switch was not enabled, and relying solely on semantic recall led to matching documents with similar ISBN numbers but unrelated projects, or the similarity threshold was set too low, introducing redundant recalls.
- Phenomenon: When an external call carries the
detail: trueparameter, the returned knowledge base call parameters and streaming results cannot be parsed correctly. Cause: The return format parameter was not correctly configured in the API request, or the external parsing logic did not adapt to the chunked data structure of streaming returns, failing to splice the complete returned content.
How to confirm the configuration is correct
- Upload a test publishing due diligence report, enter a query containing an ISBN number in the debug preview, and confirm that the corresponding document fragment can be accurately recalled.
- Trigger a simulated topic approval update event, check the knowledge base update log, and confirm that the corresponding document has completed incremental index update.
- Call the API interface with the
detail: trueparameter, and check whether the returned results include the knowledge base retrieval related parameters and recalled document list. - Adjust the similarity threshold, compare the recall results under different query scenarios, and confirm that the matching accuracy aligns with the expected adjustment direction for the business.
