What the Data for This Category Looks Like
Cement research report data sources primarily include industry monitoring data released by a national building materials industry association, securities firm industry research reports, and transaction records from third-party building material supply chain platforms. Update cycles cover daily, weekly, and monthly: daily releases national and regional cement ex-factory price data, weekly updates regional supply and demand monitoring data, and monthly releases in-depth industry research reports. Document structures include industry overview, regional market dynamics, cost breakdown, supply and demand data tables, and future market outlook. Single document word count varies widely, with professional quantitative fields including cement ex-factory price (unit: yuan/ton), regional production capacity scale (unit: 10,000 tons), monthly shipment volume, and others.
Constraints Imposed by These Characteristics on the Model Connection and Configuration Link
Cement research report data sources include structured monitoring tables and unstructured analytical text. Update cycles cover multiple frequencies, single document word count varies widely, and the data includes professional quantitative fields and industry terminology. These characteristics require the model connection link to adapt to mixed-format document parsing, configure incremental pull tasks to match data with different update frequencies, set context length thresholds to adapt to long document input, and configure dedicated entity recognition rules for cement industry professional indicators. This avoids the model confusing quantitative fields of different building material categories and ensures the accuracy of retrieval and question answering.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
maxContext | 8000–16000 tokens | Cement research reports have wide variation in single-document word count. 8000 tokens covers most short and medium-length reports, while 16000 tokens supports complete context input for long in-depth reports |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Some long research reports include structured data tables, which take longer to parse. 300 seconds avoids timeout interruptions to parsing tasks |
Recall count | Top 8–12 entries | Regional price difference and production capacity data of cement research reports have strong relevance. 8-12 entries covers complete regional market logic and avoids redundant recall |
Similarity threshold | 0.75–0.85 | Cement industry professional terminology has high recognition accuracy. This threshold filters irrelevant building material category retrieval results and improves retrieval precision |
UPLOAD_FILE_MAX_SIZE | 200 MB | Some research reports include Excel-format supply and demand balance sheet attachments. 200 MB covers most upload requirements |
Chunk size | 1000–1500 characters | Cement research reports contain a large number of professional terms and quantitative fields. Segment length adapts to the model's token splitting rules and avoids semantic breaks |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Configuration Errors
- Phenomenon: After configuring the model, a retrieval task returns a 422 status code, and the model test phase previously showed success. Cause: The structured data table fields in cement research reports contain special characters or unit suffixes, and no field filtering rules were configured during model connection, resulting in abnormal request parameter format.
- Phenomenon: After adding an external model API key, the corresponding model does not appear in the model list. Cause: External model access permission was not enabled in the platform configuration, or the model version bound to the key does not adapt to the platform's API call format.
- Phenomenon: Retrieved research report results contain content from other building material categories. Cause: The similarity threshold does not match industry characteristics, and no dedicated retrieval prompt was configured for cement industry terminology, causing the model to fail to accurately distinguish retrieval keywords.
How to Confirm the Configuration Is Complete
- Upload a single cement research report, check if the parsed text fully extracts professional fields with no obvious semantic breaks.
- Initiate a retrieval for cement regional price differences, verify that the number of returned results matches the configured retrieval range, and that the results do not contain research reports from unrelated categories.
- After configuring a scheduled pull task, check the data synchronization log to confirm that data of different cycles is updated according to the preset cycle.
- When calling an external model API, check if the platform's response contains correctly formatted professional term explanations with no error messages.
