What Data for This Category Looks Like
Telecommunications service marketing content data primarily comes from internal operator marketing platforms, customer service script libraries, and package promotional material systems. Data update rhythms align with business activities. Regular package content is updated monthly. Temporary additions or adjustments occur during holiday promotions or new service launches.
Each document typically includes five core fields: marketing scenario, applicable user tags, script text, effective time, and expiration time. Script text is stored as plain or rich text, measured in characters. Time fields use ISO 8601 format. User tags are enumerated text values.
Constraints on Knowledge Base Retrieval and Recall
Multi-source data requires cross-system synchronization. Incremental pulling is required to match temporary update frequencies, avoiding resource waste from full synchronization.
Documents include effective and expiration time fields. The retrieval process must automatically filter non-current content, preventing expired marketing scripts from being returned.
User tag fields require precise matching by tag during retrieval, avoiding returning content to ineligible users.
Scene descriptions and core text of individual scripts are bound together. Chunked retrieval must preserve contextual association, preventing semantic fragmentation that reduces matching accuracy.
Configuration Settings
| Config Item | Recommended Value | Rationale |
|---|---|---|
recall_top_k | Top 10-15 entries | Telecommunications marketing scripts are typically short in length. Too many recalled results lead to redundancy. 10-15 entries cover daily retrieval needs |
similarity_threshold | 0.72-0.85 | Semantic matching for marketing scripts has high requirements. A threshold that is too low may recall content unrelated to the current query |
rag_chunk_size | 800-1200 characters | Individual marketing scripts include scene descriptions and full script text. Oversized chunks break contextual association, reducing retrieval accuracy |
rag_chunk_overlap | 150-200 characters | Scene descriptions and core text of scripts have logical connections. Overlapping chunks preserve contextual coherence |
enable_time_filter | Enabled | Marketing content has clear effective and expiration times. Filtering non-current documents avoids returning expired content |
tag_filter_enabled | Enabled | Documents include user tag fields. Precise recall by business tags is required to adapt to marketing needs for different user groups |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to conduct tests on local samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: A custom token is used when calling the knowledge base search interface, but platform deduction fees still occur. Cause: No exclusive API channel bound to the custom secret key. The default public platform channel is used, resulting in billing.
- Phenomenon: A QA test prompts "No available channel for model gpt-4o-mini under current group default (request id: 202408300)". Cause: No API channel for gpt-4o-mini is bound in the corresponding group, or the call quota for this channel has been exhausted.
- Phenomenon: No expected results are returned when selecting knowledge base documents via variable reference. Cause: Variable parameters for tag or time filtering are not explicitly passed, or the parameter format does not match document fields.
How to Verify Correct Configuration
- Run a retrieval test for a single marketing script, verify that the effective time of returned results falls within the current time period.
- Check retrieval logs to confirm the number of returned results matches the
recall_top_kconfiguration value. - Validate a retrieval request with a specified tag, confirm that only document content matching the corresponding tag is returned.
- Check interface call billing records, confirm that no additional platform deduction fees occur when using a custom secret key.
