What data for this category looks like
Consumer building materials research report data primarily comes from public industry association reports, targeted analyses from securities firm research institutes, quarterly dynamic announcements from leading building material manufacturers, and third-party building material data platforms. Update frequency fluctuates with industry policies and quarterly earnings release deadlines, with no fixed daily update cycle. Typical document structures include research report summaries, supply and demand data for segmented product categories, product price trends, policy interpretations, and corporate ratings. Fields include publishing institution, release date, product unit price (yuan/square meter, yuan/ton), production capacity (10,000 tons/year), inventory turnover days, and more. Unit standards vary significantly across segmented categories.
Constraints imposed on HTTP interfaces and external systems
The multiple segmented categories and mixed unit standards of consumer building materials research reports require HTTP interfaces to support filtering parameters by category and unit type, to avoid returning irrelevant data. The non-fixed update frequency requires external systems to allow configurable polling intervals, without forcing full data pulls. The wide variation in length of individual research reports requires elastic adjustment options for interface parsing timeouts and recall length configurations. Additionally, differences in specialized terminology across segmented categories require the interface’s similarity matching threshold to be adapted to this field’s text characteristics, to avoid insufficient recall accuracy.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Consumer building materials research reports often include multi-page data charts, and single file size can reach the gigabyte range. 2000 MB covers most scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing a long single research report requires traversing a large number of charts and text passages. 300 seconds helps avoid parsing interruptions |
similarity_threshold | 0.72–0.78 | Consumer building materials has dense specialized terminology. A threshold that is too low will introduce irrelevant industry documents, while a threshold that is too high will lead to insufficient recall |
retrieve_top_k | Top 8 entries | Consumer building materials covers segmented tracks including tiles, pipes, waterproofing materials, and more. An appropriate number of recalls can cover multi-dimensional research report information |
maxContext | 8000 characters | The core argumentative passages of consumer building materials research reports are lengthy. 8000 characters preserves complete contextual information |
api_poll_interval | 3600 seconds | Industry research report updates primarily follow daily or weekly cycles. A 3600-second polling interval allows timely access to the latest content |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and testing against applicable samples is recommended before finalizing settings.
Three common configuration mistakes
- An HTTP interface call returns a 200 status code, but the content field in the response body is empty. This occurs because the
similarity_thresholdconfiguration is not set to the 0.72–0.78 range adapted for consumer building materials. Recalled documents do not have sufficient relevance to the retrieval query, so valid answer content cannot be generated. - An external system triggers a parsing failure error when uploading a consumer building materials research report file. This occurs because the
UPLOAD_FILE_MAX_SIZEconfiguration was not adjusted. Large research report files exceeding the set threshold are blocked, and text parsing cannot be completed. - The number of recall results returned by the interface does not match the configured
retrieve_top_kvalue. This occurs because the re-ranking return count and recall count configurations are not aligned. The default re-ranking logic filters some recall results, leading to a final return count that does not meet expectations.
How to confirm correct configuration
- Initiate a test retrieval call targeting a consumer building materials segmented category, and check if the response body includes matching research report content and standardized unit fields.
- Upload a consumer building materials research report file with a volume exceeding 1500 MB, and confirm that the interface does not return an error message indicating file size limit exceeded.
- Review interface call logs to confirm that parsing time does not exceed the preset
PARSE_FILE_TIMEOUT_SECONDSthreshold. - Compare the research report data received by the external system with the fields from the original document, to confirm that the recalled documents match the retrieval requirement’s category.
