What the data for this category looks like
Engineering consulting research report data primarily comes from specialized project financing reports from financial institutions, publicly available project filing materials from official housing and urban-rural development departments, research white papers released by industry associations, and project feasibility study reports issued by professional consulting institutions.
Update frequency varies with project progress, industry policy adjustments, or financing progress, with no fixed cycle. Some specialized reports are only released after project winning or financing implementation.
Individual documents range from thousands to tens of thousands of characters, containing fields such as project number, construction location, total investment amount, technical parameters, risk rating, financing amount, and more. Units include standard engineering units such as ten thousand yuan, square meters, days, cubic meters, and others.
What constraints do these characteristics impose on workflow orchestration
The non-fixed update cycle of engineering consulting research reports requires the workflow to support on-demand triggering to adapt to temporarily accessed specialized reports.
The wide range of individual document lengths requires flexible adjustment of the workflow's segment parsing parameters to avoid long document truncation or parsing failures.
Exclusive engineering unit fields require the retrieval link to retain original unit information to prevent mismatches between numerical values and units.
Some documents contain internal project or financing sensitive information, requiring the workflow to integrate permission verification and log desensitization links to filter data sources without valid access permissions.
The demand for multi-source data aggregation requires the workflow to support format conversion for different data sources to unify input for the retrieval link.
How to set configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600–1200 seconds | The wide range of individual document lengths for engineering consulting research reports requires longer time for long document parsing to avoid mid-process timeout interruptions |
segment_length | 800–1500 characters | Adapts to the paragraph structure of engineering documents and avoids splitting professional terms or unit combinations |
retrieve_top_k | Top 10–15 entries | Engineering consulting research reports have high professional information density, requiring retrieval of enough relevant fragments to cover core content |
similarity_threshold | 0.75–0.85 | Filters low-relevance general statements and retains research report content that strongly matches project scenarios |
workflow_call_timeout | 1800 seconds | Multi-step processing of complex research reports requires longer execution time to avoid early connection termination |
tool_call_output | Hidden | Most engineering consulting workflows are automated retrieval processes, no need to output intermediate replies from tool calls to simplify final output |
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 case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: After calling the workflow, the retrieved research report operation data in the conversation log is empty. Cause: Permission verification rules for the data source are not configured, internal project research reports are filtered, resulting in no valid data returned.
- Phenomenon: After the main workflow calls a sub-workflow, the sub-workflow cannot complete the complete research report parsing process. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter of the sub-workflow is set too short, and long document parsing is terminated before completion. - Phenomenon: Non-streaming workflow calls are forcibly disconnected after exceeding 180 seconds, and complete research report results are not returned. Cause: The
workflow_call_timeoutparameter is not adjusted, and the default timeout limit cannot cover the processing duration of long engineering documents.
How to Confirm Proper Configuration
- Upload a typical engineering consulting research report, run the workflow, check if the parsed segmented content is included in the conversation log, and adjust
segment_lengthuntil no obvious truncation occurs. - Call the workflow by passing an internal project number, verify if the returned results include the exclusive fields of the corresponding project, and confirm that the permission verification rules are configured correctly.
- Simulate a long document parsing scenario, run the workflow and observe the task execution duration, adjust
PARSE_FILE_TIMEOUT_SECONDSuntil the task can complete normally. - Check the configuration of the tool call node, confirm that the setting of
tool_call_outputmeets the output requirements of the workflow.
