Data Characteristics
Site Management Organization (SMO) regulatory documents include Standard Operating Procedures (SOPs), Work Instructions, Quality Management System documents, training records, and compliance audit reports. These documents are typically PDFs, Word files, or internal knowledge base pages. Their content is highly structured, containing specialized terminology, process descriptions, role responsibilities, risk control measures, and regulatory citations. Update frequency often aligns with regulatory changes, internal process optimizations, or project needs, occurring quarterly, annually, or immediately after specific events. Fields commonly found in these documents include version numbers, effective dates, revision histories, responsible departments, and reference document numbers. Units often involve time (e.g., days, hours), quantity (e.g., copies, person-times), and percentages (e.g., pass rate).
Constraints on Vector Models and Indexing
The specialized and structured nature of SMO regulatory documents requires vector models to accurately capture semantic relationships of specialized terms and distinguish subtle differences in process steps. Frequent version numbers and revision histories mean index updates must support incremental updates and version management to ensure timely and accurate retrieval. Extensive process descriptions and compliance requirements necessitate document segmentation that maintains semantic integrity, preventing the splitting of critical processes or clauses. The ability to identify reference document numbers helps provide comprehensive contextual information during question answering. The unpredictable document update frequency challenges index reconstruction strategies, requiring a balance between update efficiency and resource consumption.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
Chunk size | 800–1200 characters | Balances semantic integrity and recall efficiency, preventing long texts from diluting key information. |
Recall count | Top 5 entries | Balances relevance and model processing capacity, covering primary relevant content. |
Similarity threshold | 0.75–0.85 | Ensures precision of recalled content, filtering out irrelevant or weakly related segments. |
Rerank result count | 3 entries | Further refines results, providing the most core answer support. |
embeddingModel | Doubao-embedding | Suitable for semantic understanding of Chinese professional texts, providing high-quality vector representations. |
Update Strategy | By Version Number Trigger | Ensures timely index updates after document revisions, guaranteeing timeliness. |
Common Pitfalls
- The progress bar may freeze after switching vector models, with no status updates for an extended period. This indicates a potential issue with the new model's configuration or a connection timeout.
- A
404 page not foerror message when configuring the Doubao index model usually means incorrectAPI_KEYorBASE_URLsettings, preventing access to the model service interface. - Retrieval results may contain numerous irrelevant or outdated regulatory clauses. This suggests the segmentation strategy failed to maintain semantic coherence, or the index did not synchronize with the latest versions in time.
Verification Steps
- Select a recently updated SOP document. Submit relevant questions and check if the recalled results include the document's latest content.
- For a document containing process steps, ask about the execution requirements of a specific stage. Verify if the recalled segments fully cover that process.
- Randomly select multiple regulatory documents. Submit queries about responsible departments or referenced documents. Validate the accuracy of the recalled results.
- Check system logs for successful vector model calls, abnormal status codes, or timeout records.
