What the Data for This Category Looks Like
Data sources primarily include publicly available statistical materials from domestic building material industry associations, research reports on the consumer building materials track from securities firm research institutes, and annual reports and quarterly operation briefings from leading building material enterprises. Update rhythm adjusts according to research report release cycles: industry association data is updated quarterly, while securities firm research reports are released irregularly alongside research progress. Document structure typically includes four core modules: overall track overview, supply and demand data for segmented products, price trend analysis, and policy impact interpretation. Fields include report release date, covered provinces, product unit price, monthly shipment volume, and production capacity scale, with units being date, province, yuan/square meter, ten thousand units, and ten thousand tons respectively.
What Constraints Do These Characteristics Impose on the Knowledge Base Retrieval and Recall Link
Multi-source and heterogeneous data sources lead to differences in format and expression logic across different documents, requiring differentiation of data credibility weights during the recall stage. Second, update rhythms are inconsistent: quarterly updated industry data and irregularly released securities firm research reports need to adapt to incremental synchronization logic to avoid redundant old data or missed new data. Furthermore, documents include numeric fields and dimensional fields, so retrieval must support multi-condition filtering by region, release time, and product type, while adapting to document segments of different lengths to avoid truncating key information in long documents or wasting recall quotas for short documents. Additionally, unifying units for numeric fields such as product unit price and shipment volume across segmented categories is difficult, requiring verification of field matching during recall.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
recall count | Top 10-15 results | There are many segmented tracks for consumer building materials research reports, so a single round of retrieval needs to cover enough track dimensions to avoid missing key data |
similarity threshold | 0.75-0.85 | There are many technical terms in consumer building materials research reports, so it is necessary to balance recall relevance and coverage. An overly high threshold will miss segmented track data, while an overly low threshold will introduce irrelevant content |
segment length | 800-1200 characters | A single research report contains multi-dimensional data, and the segment length adapts to the semantic integrity of technical terms to avoid truncating key numeric information such as product unit price and shipment volume |
knowledge base incremental update cycle | Once per week | Securities firm research reports are released irregularly, while industry association data is updated quarterly. Weekly synchronization balances the timeliness of new data and synchronization efficiency |
search citation limit | 13000 characters for knowledge base search nodes, 3000 characters for workflow invocation nodes | Knowledge base search nodes can directly connect to large model context quotas. Workflow invocation is limited by link transmission, so the quota needs to be reduced to avoid timeouts |
reranked result count | Top 5-8 results | Filter redundant recall results and retain core research report content that best matches the retrieval intent |
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, and specific issues require specific analysis. It is recommended to test on your own samples before finalizing.
Three Common Misconfigurations
- Phenomenon: When invoking knowledge base search within a workflow, the number of returned results is far lower than expected, and logs show context truncation. Cause: Failure to distinguish between the citation limit configuration for knowledge base search nodes and workflow invocation nodes, incorrectly applying the 13000-character limit from the search configuration to workflow scenarios, leading to link transmission limit truncation.
- Phenomenon: Non-consumer building materials category research report content is mixed in retrieval results. Cause: No filtering rules configured by product tags or track fields, failing to limit the retrieval scope to the consumer building materials segmented track.
- Phenomenon: Latest securities firm research report data is missing from retrieval results. Cause: The knowledge base incremental update cycle is set too long, failing to align with the irregular release rhythm of securities firm research reports, leading to new data not being synchronized to the knowledge base in a timely manner.
How to Confirm the Configuration Is Correct
- Initiate a retrieval containing keywords for consumer building materials segmented categories, verify that the covered tracks of returned results match the target categories.
- Check the knowledge base update log to confirm whether the latest released research reports have completed synchronization within the set update cycle.
- Test the knowledge base search node invoked within a workflow, verify that the context length of returned results complies with the transmission limits of the workflow link.
- Adjust the similarity threshold and initiate a retrieval, verify that the relevance of returned results meets expectations.
