What the data for this category looks like
Data sources for e-commerce service marketing content targeting financial institutions include marketing material libraries built by e-commerce service teams, product marketing copy from partner financial brands, platform activity rule documents, script templates from past customer acquisition conversions, and compiled high-frequency customer service questions. Data updates are adjusted according to business cycles. Concentrated updates occur before major promotion events, with iterative updates on demand during regular periods. Each individual document includes a unique identifier, applicable scenario tags, applicable channel tags, content text, effective time, and expiration time. Fields include a string-type unique identifier, enumerated scenario and channel tags, and ISO-formatted timeliness information. The character count of content text is measured in individual characters.
What constraints these characteristics impose on the knowledge base retrieval and recall workflow
Multiple scattered data sources require the preprocessing step to support different formats and tag systems. Unified field mapping rules must be implemented to ensure valid tag matching during retrieval. Content includes timeliness tags. The retrieval step must automatically filter expired materials using effective and expiration times. This prevents returning invalid marketing content. Individual content covers multiple scenarios and channels. After retrieval, results must be sorted by scenario matching degree to improve accuracy. Update frequency fluctuates with business cycles. Bulk content additions may occur before major promotions. The system must support incremental synchronization to avoid full reindexing. This reduces resource usage and latency in the retrieval step.
Configuration Recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_SEGMENT_LENGTH | 800–1200 characters | E-commerce marketing content is mostly paragraph-based copy. This segment length fits most large model context windows, while avoiding semantic fragmentation caused by overly long single segments |
RECALL_TOP_K | Top 8–12 results | The e-commerce marketing content category has wide coverage. Sufficient recall results are needed to cover different scenarios, while avoiding redundant content interfering with final output |
SIMILARITY_THRESHOLD | 0.75–0.85 | Marketing content has relatively high semantic similarity. This threshold range filters irrelevant content, while retaining materials that meet matching requirements and fit target scenarios |
RERANK_TOP_K | Top 3–5 results | After reranking the recalled candidate content, only the results most closely matching user queries are retained. This reduces information noise in the generation step |
SYNC_INCREMENTAL_MODE | Incremental sync by timestamp | E-commerce marketing content update frequency fluctuates with business cycles. Incremental sync reduces repeated processing and improves knowledge base update efficiency |
AUTO_FILTER_EXPIRED | Enabled | Marketing content includes effective and expiration time tags. Automatically filtering expired materials improves the timeliness of recalled content |
The parameter values provided on this page are standard recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific scenarios require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Symptom: Retrieval response time is too long. The frontend displays a load timeout or
504 Gateway Timeouterror code. Cause: Incremental sync mode is not enabled. Full scanning of all knowledge base content is performed, and the upper limit of recalled results is not restricted. This causes excessive resource usage in vector retrieval and reranking steps. - Symptom: Returned marketing content includes expired copy from discontinued campaigns. Cause: The
AUTO_FILTER_EXPIREDconfiguration is not enabled, or the effective and expiration time fields for content are not properly configured. This prevents the retrieval step from identifying expired materials. - Symptom: Calling the knowledge base does not return locally configured marketing materials, only generic responses. Cause: The marketing material library is not bound to the corresponding knowledge base application, or retrieval permissions for the local knowledge base are not enabled. This causes the retrieval scope to not cover the target material library.
How to Confirm Proper Configuration
- Upload one marketing material with effective and expiration times. Initiate a query matching the material's scenario. Verify that the returned results include this material and do not include similar expired materials.
- Simulate bulk import of marketing materials. Check synchronization progress and time consumption. Confirm that incremental sync mode is active, with no abnormal full reindexing records.
- Adjust retrieval-related configurations. Initiate multi-scenario queries. Verify that the number and matching degree of returned results meet business expectations.
- Enable the streaming reply switch. Initiate a query. Verify that reply content is output incrementally in segments.
