Data Characteristics for This Category
Retail chain policies and SOP data originate from internal company regulations, operational manuals, training materials, and internal notices. These documents are typically in PDF, Word, or internal knowledge management system page formats. Data update frequency is relatively stable, usually revised quarterly or annually, with immediate updates for major policy changes or business process modifications. Document structure is rigorous, typically including standardized fields like title, chapter, clause, specific operating steps, responsible department, and approval process. Field content often involves store codes, product categories, operational deadlines, and penalty amounts, with units commonly in days, hours, percentages, or CNY.
Constraints from These Characteristics on "Citation and Traceability"
The strictness of retail chain policies demands that Q&A results are highly accurate and traceable to the original text. This prevents misleading store operations or creating compliance risks. The relatively stable update frequency means the knowledge base content requires regular synchronization, but not overly frequent updates. Diverse document formats and structures necessitate text extraction tools with good compatibility. Specific fields and units within documents, such as "store code" or "penalty amount," require the Q&A system to precisely identify and present them in citations, ensuring contextual completeness and verifiability. Additionally, since policy clauses often cross-reference each other, the system must handle complex citation relationships, pointing to multiple relevant original text segments.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale for Recommendation |
|---|---|---|
Chunk Length | 800–1200 characters | Individual clauses or operational steps in policy documents are often long. This range helps maintain semantic integrity and reduces misinterpretation. |
Recall Count | Top 5–7 entries | Ensures coverage of multiple relevant policy clauses for complex queries, improving answer comprehensiveness. |
Similarity Threshold | 0.78–0.85 | Retail policies demand high accuracy. This threshold helps filter out low-relevance segments, reducing noise. |
Rerank Return Count | Top 3 entries | Focuses on the most relevant entries within the recalled results for fine-grained ranking, enhancing user experience. |
maxContext | 4000–6000 tokens | Addresses long policy clauses or cross-chapter references, ensuring the model has sufficient context to understand and generate accurate answers. |
Knowledge Base Max Citation | 3–5 segments | Balances information completeness with response length, avoiding excessive citations that burden the user. |
Three Common Mistakes
- The model's answer lacks a link to the original text or specific clause number, preventing users from verifying the answer's accuracy. This usually occurs when the
Knowledge Base Max Citationparameter is set too low, or the model is not effectively guided to cite sources during answer generation. - When processing policy documents containing tables or images, text extraction is incomplete, leading to inaccurate Q&A results or missing citation segments. This happens because the file parser has insufficient support for complex layouts, failing to correctly extract all key information.
- When users ask complex questions spanning multiple policy documents or chapters, the model cites irrelevant segments or produces "red errors," indicating that the referenced original content cannot be found. This may be due to a knowledge base chunking strategy that does not adequately consider inter-policy relationships, or a vector database index that fails to effectively handle multi-document associative queries.
How to Confirm Proper Configuration
- Select typical complex questions from retail chain policies and test if FastGPT's answers are accurate. Verify that all citation links navigate to the correct location in the original text or display the correct clause number.
- For critical SOP documents containing charts or flowcharts, check if the model accurately understands their content and provides correct answers. Simultaneously, verify if its citations point to the charts or relevant textual descriptions.
- Simulate a scenario after policy updates: upload new policy documents and test if the Q&A system prioritizes citing the latest version. Verify if old policy citations are invalidated or correctly replaced.
- Randomly select multiple Q&A results and cross-reference their cited original segments. Ensure that the cited content highly matches the answer's semantics and that no misinterpretations occur.
