What the data for this category looks like
Data sources for glass research reports include monthly production capacity reports from the China Building Glass and Industrial Glass Association, daily quotes from spot trading platforms, building materials industry research reports from securities firms, and public data from downstream application enterprises. Update frequencies vary across sources: spot quote data updates daily, industry research reports update weekly or biweekly, and production capacity and downstream demand data update monthly. Each research report includes core indicator tables, downstream demand breakdowns, cost-side analysis, and trend forecasts. Core fields include glass thickness (unit: millimeter), spot price (unit: yuan/weight box), designed production capacity (unit: ten thousand weight boxes/month), and raw material soda ash price (unit: yuan/ton). Field names differ slightly across sources.
What constraints do these characteristics impose on workflow orchestration
Differing update schedules across multi-source glass research report data require configuration of multiple scheduled trigger rules, each aligned with the pull cycle of a specific data source. Documents contain both structured tables and unstructured analysis content. Add a structured parsing node to the workflow to extract retrievable fields such as thickness and price, avoiding reliance on fuzzy matching from full-text vector retrieval alone. Differences in field names and units across sources require configuration of field mapping and unit conversion nodes to unify retrieval standards. Glass research reports tie to downstream segments including real estate and automobiles. Add an associated query node to the workflow to ensure retrieval results cover complete industry logic. The glass category has many specification variants. Configure specification filter conditions during the retrieval phase to narrow the search scope.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
rag_retrieve_top_k | Top 8 entries | Glass research reports have many segmented indicators. Too many recalled entries increase context processing burden, while too few will miss key segmented data |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Individual glass research reports have long length, so sufficient time must be reserved for document parsing |
maxContext | 1000–1400 characters | Adapts to long-paragraph industry analysis and demand breakdown content in glass research reports |
rag_similarity_threshold | 0.72–0.85 | Filters low-relevance non-glass building material content, ensuring retrieval results focus on the glass sector |
global_variable_data_type | Enumeration | Limits the optional range of knowledge base selection variables to glass-related knowledge bases, preventing selection of incorrect data sources |
rag_table_extract_enable | Enabled | Extracts structured quote tables from research reports for precise matching of core fields such as thickness, region, and price |
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. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: The workflow returns duplicate research report content, or fails to merge multiple research report fragments on the same topic. Cause: The
rag_query_mergeconfiguration is not enabled, and duplicate retrieval results are not deduplicated and merged. - Phenomenon: Invalid input occurs when selecting a knowledge base via global variables, or the variable fails to bind to the preset glass research report knowledge base. Cause: The knowledge base selection variable is not configured as an enumeration type, allowing free input which causes matching failures.
- Phenomenon: Documents cannot be uploaded in the workflow, and the upload button has no response. Cause: The
UPLOAD_FILE_MAX_SIZEparameter is not configured to allow uploading research report PDF/Word files, or the workflow’s file upload permission is not enabled.
How to Confirm Proper Configuration
- Run a single test retrieval, enter specified glass thickness and region keywords, and verify that returned result fields include the configured filter conditions.
- View the workflow’s scheduled trigger logs, and verify that synchronization cycles for different data sources match preset rules.
- Upload a test glass research report document, and verify that the parsing result extracts structured table content.
- Test the global variable’s knowledge base selection function, and confirm that only preset glass-related knowledge bases can be selected.
