Data Characteristics
Retail chain quality documentation includes internal regulations, operating manuals, store inspection reports, supplier qualification certificates, and batch inspection reports for pharmaceuticals and medical devices. These documents update frequently. Store inspection reports and batch inspection reports may have daily or weekly additions. Regulations and operating manuals are typically long, structured texts with titles, chapters, and clauses. Inspection reports are often semi-structured, containing fields for inspection items, results, and corrective actions. Batch reports have fixed fields such as product name, batch number, production date, expiration date, and inspection results. Units vary; for example, "production date" is a date format, "expiration date" can be a date or number of days, and "inspection results" may include numerical and qualitative descriptions.
Constraints on Citation and Traceability
The characteristics of retail chain quality documentation impose several constraints on citation and traceability. High update frequency requires efficient incremental updates and version management in the knowledge base to ensure citations are current. Long, structured documents need fine-grained text segmentation to avoid redundant information or loss of critical context. The presence of semi-structured and fixed-field data challenges traditional vector retrieval, necessitating a combination of keyword matching or structured queries for accurate field-specific information retrieval. Document diversity requires the system to integrate data from various storage systems (e.g., file systems, databases, enterprise content management systems). The system must clearly indicate original sources—such as specific file names, version numbers, or database record IDs—which is crucial for compliance audits.
Configuration Guide
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Segment Length) | 800–1200 characters (characters) | Accommodates long texts like regulations, ensuring segment completeness and minimizing context loss. |
Recall count (Recall Count) | 5 entries (items) | Balances recall efficiency and information completeness, covering key information from various sources. |
Similarity threshold (Similarity Threshold) | Calibrate by actual measurement (Calibrate based on actual measurements) | Ensures high relevance of recalled content to query intent, reducing interference from irrelevant documents. |
Rerank result count (Reranked Return Count) | 3 entries (items) | Focuses on the most relevant citations, optimizing the reference value for engineers. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds (seconds) | Handles parsing large regulation documents or batch reports, preventing timeouts during data processing. |
UPLOAD_FILE_MAX_SIZE | 500 MB | Supports uploading inspection reports and qualification certificates containing numerous images or scanned documents. |
Common Pitfalls
- Failure to cite English documents from the knowledge base after a query. This occurs when the tokenizer is not optimized for multilingual content, preventing correct indexing of English technical terms.
- Knowledge base returns content unrelated to the query. This symptom indicates that the similarity threshold (
Similarity threshold) is set too low, leading to the recall of many irrelevant items. - Citation sources appear empty or incomplete. This happens when metadata is not parsed correctly during document upload, or when the original document's storage path or version information is not properly associated during knowledge base construction.
Verification Steps
- Query with typical questions. Check if the returned citation sources clearly point to specific sections or paragraphs of the original document and identify the file name or version number.
- Query for specific inspection items in inspection reports or product batch numbers in batch reports. Verify that the returned content accurately extracts the relevant field information.
- Simulate document updates by uploading new versions of regulations or new inspection reports. Verify that the knowledge base promptly indexes and cites the latest content, while older versions remain traceable.
