What the data for this category looks like
Infrastructure engineering enterprises’ financial report data comes primarily from publicly disclosed periodic reports, project settlement ledgers, and industry regulatory public information. Update schedules follow regulatory requirements: quarterly reports release within one month after the end of the quarter, and annual reports disclose within four months after the end of the year. A single financial report document includes fields such as total project contract value, under-construction project output value, breakdown of cost components, and accounts receivable balance. Output value and contract value use ten thousand yuan or hundred million yuan as units, project duration uses natural months or calendar days, and single project construction area uses square meters. Some subcategories also include specialized fields such as special equipment usage duration.
What constraints do these characteristics impose on tool calling and plugins
The multi-source, dispersed nature of infrastructure engineering financial report data requires tool calling to support a mixed access model: pull regulatory public data via public APIs, and upload settlement ledgers as local files. Data sources with different update cycles need plugins to configure scheduled synchronization tasks, with separate trigger logic for quarterly incremental updates and annual full updates. The numerous detailed fields and their varying units require the tool’s field mapping module to support custom unit conversion rules, to fix unit mismatches for fields like output value and area. The long document structure needs the plugin’s document parsing link to adapt to long text segmentation rules, preventing key project information from being cut off.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Infrastructure engineering financial reports and supporting ledger documents have lengthy content with multiple project detail data, so standard timeout periods cannot complete full parsing |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single infrastructure financial report and associated engineering files have large volume, so need to support batch uploads of large files |
maxContext | 8000–12000 characters | Infrastructure financial reports require retaining multi-dimensional associated information such as project contracts, output value, and costs; longer context can prevent key data from being truncated |
Recall count | Top 8–10 entries | Core analysis information for infrastructure financial reports is scattered across multiple paragraphs, so sufficient relevant fragments need to be recalled to support complete analysis |
Similarity threshold | 0.72–0.78 | The infrastructure industry has unified field naming specifications; adjusting the threshold can prevent similar data from unrelated projects from being incorrectly recalled |
plugin_sync_interval | Every 7 days | The update cycle for quarterly financial reports is 1 month; setting a 7-day synchronization interval allows timely access to the latest project settlement and financial report data |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, 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: Analysis results returned via API calls do not include referenced source file names and page numbers. Cause: The
return_source_infoconfiguration item is not enabled, or source file metadata storage is not enabled during the vector recall process. - Phenomenon: A
403 Forbiddenerror is returned when calling the knowledge base query interface with an application key. Cause: Application keys only support calls for front-end embedding scenarios; back-end interface calls require independent API keys, and the permission scopes of the two types of keys differ. - Phenomenon: Unable to locate the corresponding configuration entry when attempting to create a team custom plugin. Cause: Plugin development permissions are not enabled in the team management backend, or the current account has not been assigned plugin development role permissions.
How to Confirm Configuration is Successful
- Upload a test infrastructure engineering financial report document, check if the parsed field list includes custom specialized fields to confirm that the parsing rules are effective.
- Initiate a tool call request, check the status code and execution log of the returned results to confirm that no parsing timeout exception is triggered.
- After configuring the plugin synchronization task, check the data source update record list to confirm that the task is triggered according to the preset cycle and completes data synchronization.
- Adjust the similarity threshold, initiate a knowledge base recall request, observe the number of recall results to confirm that the threshold configuration is effective.
