What the Data for This Category Looks Like
Marketing content data sources include internal marketing platforms, CRM systems, digital archives of offline promotional materials, and official public account material repositories. Updates trigger in real time when marketing campaigns launch, with emergency updates for major product adjustments, and routine maintenance conducted quarterly or monthly. Document structures fall into three categories: structured product information, scenario-based marketing scripts, and promotional copy. Fields include material name, target customer group, delivery channel, and associated product ID. Units include yuan, days, months, and others.
Constraints Imposed on Knowledge Base Retrieval and Recall
Multi-source heterogeneous data sources include structured tables, plain text scripts, and scanned materials. The retrieval system must support cross-format parsing and unified vector indexing to avoid leaving some materials unretrievable. Real-time updates and frequent new marketing material additions require configuring an incremental synchronization mechanism. This reduces the time cost of full indexing, and ensures newly launched marketing content can be retrieved quickly. Mixed document structures combine structured fields and unstructured text. The system must support hybrid retrieval logic that combines keyword matching and vector recall. Exclusive business fields such as target customer group and delivery channel require field-based filtering of recall results. This ensures returned marketing content aligns with current marketing scenario requirements.
Recommended Configuration Parameters
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Handles multi-page brochures or complex structured product lists of marketing materials, avoids parsing timeouts |
UPLOAD_BATCH_MAX_SIZE | 20 files per batch | Adapts to batch import of monthly marketing materials, avoids overload during single imports |
chunk_size | 800–1200 characters | Adapts to the text length of marketing scripts and product descriptions, balances context completeness and retrieval accuracy |
similarity_threshold | 0.75–0.85 | Filters low-match irrelevant marketing content, meets the precision requirements of marketing scenarios |
recall_top_k | Top 10 results | Covers candidate results for common marketing scenarios, avoids missing high-match content |
enable_field_index | Enabled | Supports filtering recall results by exclusive fields such as target customer group and delivery channel, adapts to business scenarios |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require specific analysis, and it is recommended to test using applicable internal samples before finalizing.
Three Common Configuration Mistakes
- Phenomenon: For instances deployed on Alibaba Cloud, knowledge base retrieval response time exceeds 10 seconds, with obvious delay in returned results. Cause: No incremental indexing mechanism is configured, and the number of marketing materials covered by full indexing is large, causing full scans to trigger for every retrieval.
- Phenomenon: After importing structured table marketing data, retrieval cannot match exclusive field content within the table. Cause: The
enable_field_indexconfiguration is not enabled, and no index is built for the business fields in the table. - Phenomenon: Recall results include offline marketing campaign materials, which do not meet current marketing cycle requirements. Cause: The effective time field of materials is not used as a retrieval filter condition, and no time range verification is added to the recall logic.
How to Verify Correct Configuration
- Upload a batch of test marketing materials, wait for indexing to complete, input material name keywords through the retrieval interface, and confirm that returned results include expected content.
- When calling the retrieval interface, pass filter parameters for target customer group and delivery channel, and confirm that returned results only include materials matching the corresponding conditions.
- After uploading new marketing materials, wait for the configured incremental synchronization cycle to end, retrieve the new material keywords again, and confirm that the new content has been added to the retrieval scope.
- View the FastGPT parsing log to confirm that all imported marketing materials have completed parsing with no error messages.
