What the Data for This Category Looks Like
Data sources for decoration industry research reports include public industry reports from the China Building Decoration Association, research reports from securities firm building materials teams, and bidding announcement documents from local housing and urban-rural development departments. Update frequency aligns with industry policy releases, monthly building material price fluctuations, and quarterly industry review reports. Document structures include industry overviews, segmented category breakdowns, core indicator tables, and policy interpretation modules. Fields include building material category names, unit prices (yuan per square meter), number of ongoing projects, construction cycles (days), and policy issuing authorities.
Constraints Imposed on Workflow Orchestration
These characteristics impose constraints on workflow orchestration. Decoration industry research reports have diverse data sources, including PDF, web pages, spreadsheet documents and other formats. The workflow must support parsing rules for multiple file types. Update frequency is inconsistent: some data is updated in real time for monthly building material price fluctuations, while other data comes from quarterly industry review reports. Distinct trigger logic is required for incremental updates and full updates. Documents contain nested tables and multi-dimensional indicator fields. Precise field mapping rules must be configured to avoid indicator confusion during retrieval. Some research reports are linked to local bidding project data. Additional configuration of cross-data source association node logic is required.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Decoration industry research reports often contain nested tables and long text passages. 300 seconds covers complete parsing requirements for most documents |
Recall count | Top 8–12 entries | Core indicators of research reports are scattered across different modules. This range balances context information volume and retrieval accuracy |
Similarity threshold | 0.72–0.80 | Similar naming exists for decoration building material categories. This interval avoids filtering valid matches or introducing irrelevant results |
Global Variable Update Trigger Node | After database write node | Industry indicator variables must be updated synchronously after research report data is written to the database, for use by subsequent workflow nodes |
Chunk size | 1000–1200 characters | Long passages in research reports are often linked to multiple sets of indicators. This segment range preserves indicator logic while avoiding context overflow |
Database Connection Timeout | 60 seconds | Sufficient connection time must be reserved when reading research report datasets in batches, to adapt to multi-document batch processing scenarios |
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. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Workflow runs return the
Access denied for usererror. This occurs when the access whitelist for the decoration industry research report-specific database is not configured, or the account permission range does not cover reading research report data. - After the tool call node executes, the global variable is not updated to the latest research report indicator value. This occurs when the global variable update node is not configured after the tool call trigger node, or the configuration does not adapt to the global variable synchronization rules added in version V4.9.7.
- The single-choice variable of the user selection node is not loaded into the building material category list in the research report. This occurs when the variable data source is not bound to the category field of the research report database, or the variable type does not match the text option type.
How to Verify Successful Configuration
- Run a single parsing test task, check if the parsed document fields match the preset decoration industry research report fields.
- Trigger an incremental update task, verify that the update time of newly added data in the database matches the research report release time.
- Call the retrieval node, enter a specified building material category keyword, check if the returned results include indicator data for the corresponding category.
- Trigger the tool call node, view if the global variable panel is updated to the latest research report statistical values.
