What the Data for This Category Looks Like
Data sources for refractory materials financing daily reports include public financing announcements from the National Enterprise Credit Information Publicity System, daily broadcasts from refractory materials industry information platforms, and independent disclosure information from upstream and downstream enterprises. Data sync runs every early morning, covering all financing events from the previous day. Each document is presented as a daily summary. Each financing entry includes six core fields: full name of the financing subject, associated refractory material category, financing amount, financing method, announcement date, and producing area. Financing amount units are uniformly ten thousand yuan RMB. Announcement dates use the YYYY-MM-DD format. The category field must specify a specific refractory material grade or application scenario.
What Constraints Do These Characteristics Impose on Knowledge Base Retrieval and Recall
Multiple data sources lead to differences in field formats. For example, financing amount may use either "万元" or "万", which causes missed detections during keyword matching. Field normalization processing must be completed first. The daily update rhythm requires the retrieval system to support incremental synchronization. This prevents excessive resource usage from full index rebuilding. Each financing event document is short, with core information concentrated in a small number of fields. The keyword matching weight of recall rules must be adjusted to avoid missed recall caused by ambiguous short text semantics. The category-specific field requires binding tags during retrieval. This ensures recall results are strongly related to the target refractory material category.
How to Set the Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall count | Top 10 | Single entry of refractory materials financing daily reports is short. Retrieving more results can cover different financing subjects and categories, and avoid missing core information |
similarity threshold | 0.72-0.85 | Core retrieval fields such as refractory material category and financing subject require high matching accuracy. This range can filter low-relevance results |
incremental sync interval | 24 hours | Data updates daily. Incremental synchronization avoids resource usage caused by full index rebuilding |
field weight configuration | Financing subject:1.5, refractory material category:1.8, financing amount:1.2 | Category and financing subject are core retrieval dimensions, so their weight settings are higher than the general amount field |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Single daily report document has moderate length. This timeout setting avoids interruptions during batch processing |
chunk_overlap | 100 characters | Short documents need to retain contextual association, to avoid information loss caused by semantic segmentation |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing the configuration.
Three Common Configuration Mistakes
- Phenomenon: The interface returns a
quote type errorerror, prompting that the variable format is abnormal. Cause: Knowledge base fields are not referenced in the standard{{variable name}}format, or special characters in the field name are not escaped. - Phenomenon: The number of retrieval results is much lower than expected. The same content can be recalled in a new knowledge base but not in the original one. Cause: The original knowledge base’s
similarity thresholdis set too high, or the directional matching rule for refractory material category tags is not enabled. - Phenomenon: Retrieval results do not display the knowledge base reference source. Cause: The interface’s
display reference sourceswitch is not enabled, or reference log output is disabled in the configuration.
How to Confirm the Configuration Is Complete
- Upload a single refractory materials financing daily report document, run a retrieval test for the specified category, and check if returned results include the target refractory material category keywords.
- View the index synchronization log, confirm that the incremental synchronization task’s execution cycle matches the data update node as specified in the configuration.
- Input a knowledge base field reference in standard format, verify if a
quote type erroroccurs, and confirm the format configuration is correct. - Adjust the
similarity thresholdto run multiple retrieval rounds, compare changes in the number of results, and verify that the configuration takes effect as expected.
