What This Category of Data Looks Like
Glass industry research data comes from multiple sources: national building materials industry standards (including float glass and tempered glass national standard series), bulk commodity market platforms for upstream raw materials (quartz sand, soda ash), factory quotation systems of production enterprises, third-party test reports for glass performance, and demand survey data from downstream construction and automotive industries. Update frequencies differ: raw material market data updates daily, factory quotations update weekly, and industry standards and test report templates update irregularly. Document formats include structured market quotation tables, unstructured PDF test reports, and long-form industry research reports. Common fields and units include thickness (mm), light transmittance (%), bending strength (MPa), batch number, implementation standard number, and production enterprise name.
Constraints for Citation Source and Traceability
Mixed structured and unstructured document types require the traceability process to support both field-level traceability for structured data and full-text association for unstructured documents. Data sources with different update frequencies require distinguishing real-time market data from fixed-version standard documents during traceability, to avoid citing expired content. Diverse fields and units require retaining original unit information during traceability, to prevent confusion of performance data across different glass categories. Multi-dimensional association for segmented glass categories requires traceability to cover three tiers: upstream raw materials, production batches, and downstream applications. Failing to cover all three tiers will break complete research logic.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 20 entries | Glass industry research data mostly consists of precise information for segmented categories. Too many recalled entries will dilute relevance, while too few will miss critical raw material market data |
Similarity threshold | 0.72–0.80 | Text similarity across glass test reports is relatively high. A threshold that is too low will introduce irrelevant data from other building materials, while a threshold that is too high will miss test data for the same category but different batches |
Chunk size | 800–1200 characters | Single segments of glass test reports typically contain complete test indicators. Segments that are too long will cause context fragmentation, while segments that are too short will lose association between indicators |
Maximum Trace Association Level | 3 | Glass industry research data associates with three tiers: upstream raw materials, production batches, and downstream applications. Exceeding this tier will introduce irrelevant supply chain data |
File Version Lock Switch | Enabled | Glass industry standards and test reports have clear version numbers. Locking versions prevents citing expired standard data during traceability |
maxContext | Calibrated via actual testing | Must align with Recall count and segmentation length to avoid key data loss from context truncation |
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 individual analysis, and it is recommended to confirm settings after testing with your own samples.
Three Common Misconfigurations
- Phenomenon: The number of model context entries displayed on the page differs from the actual number of sent citations. For example, 30 entries are displayed but 310 are actually sent. Cause: The
Recall countandmaxContextconfiguration parameters are not properly aligned, and context truncation rules do not match recall logic. - Phenomenon: After setting
Citation limitto 1500, knowledge base blocks exceeding this length are still included in citations. Cause: The single-block content length verification function is not enabled, and the system does not filter knowledge base blocks that exceed the limit. - Phenomenon: Traceability cannot associate original batch data from glass test reports. Cause: The
Maximum Trace Association Levelis not configured, and the switch for associating upstream raw material data sources is not enabled, limiting traceability to the current category document only.
How to Verify Correct Configuration
- View the knowledge base's segmentation configuration log to confirm that the segmentation length falls within the
800–1200 charactersrange. - Send a test request, compare the number of context entries displayed on the page with the number of citations returned by the API, to confirm that the parameter configurations match.
- Import a glass test report document that exceeds the preset
Citation limitvalue, to verify that the system triggers the length verification block. - View the traceability details page to confirm that associated upstream raw material data and industry standard versions are correctly displayed.
