Data Profile for This Category
Data sources for infrastructure construction project financing daily reports include public announcement documents from local housing and urban-rural development authorities, financing progress documents disclosed by urban investment entities, and daily summary reports from third-party industry monitoring institutions. Update frequency is daily, or per individual project launch node. Most documents are editable PDFs or structured tables. They include fields such as project name, affiliated region, total investment amount, financing amount, financing method, and fund arrival time. Amount units are mostly ten thousand yuan or hundred million yuan. Region fields are precise to the district and county level. Some documents include paragraph content explaining project progress.
Constraints for Parsing and Chunking
These characteristics impose multiple constraints on the parsing and chunking process: First, structured tables are the core carrier, with strong field correlations. Parsing must retain contextual connections between cells, and avoid splitting project information across cells. Second, amount fields appear in both uppercase and lowercase forms. Unified normalization processing is required to ensure retrieval consistency. Third, batch daily updated documents contain duplicate project identifiers. Duplicate data chunks must be filtered during chunking. Fourth, some third-party monitoring documents have cross-page tables. Cross-page table content must be automatically stitched to avoid information breaks.
Configuration Settings
The following table outlines recommended configuration values and their rationale:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Infrastructure construction project financing daily reports use structured tables as their core carrier. Enabling this setting allows complete extraction of field association information within tables |
maxChunkSize | 800–1200 characters | A single project’s information in a daily report is approximately 300–500 characters. This range retains complete contextual information for the project, its affiliated region, and financing amount |
PARSE_SCAN_PDF_ENABLE | Enabled based on document type | Some third-party monitoring documents use image-format tables. Enabling this setting allows text extraction via OCR |
UPLOAD_FILE_MAX_SIZE | 500 MB | The size of individual daily summary documents imported in batches typically does not exceed 300 MB, with reasonable buffer space reserved |
chunkOverlap | 100–150 characters | Cross-segment project association information must be retained to avoid contextual breaks |
PARSE_REMOVE_DUPLICATE | Enabled | Daily updated financing daily reports contain duplicate project entries. Enabling this setting allows automatic filtering of duplicate data chunks |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: Parsing fails when a Yuque public share link is used as a knowledge base data source. Reason: The Yuque public share link does not have external crawling permission enabled, or the link is a dynamic link with temporary session parameters, making stable parsing impossible.
- Phenomenon: Parameters are parsed correctly when calling an HTTP tool, but the corresponding request is not executed. Reason: The request timeout setting in the tool configuration is too short, or the request header does not include required authentication fields, causing the request to be intercepted and not triggered.
- Phenomenon: Imported PDF knowledge base files cannot be opened in search results. Reason: Document preview association configuration is not enabled, or original file path mapping information was not retained during parsing, making it impossible to link to the original file.
How to Confirm Configuration is Correct
- Upload a typical infrastructure construction project financing daily report document, and check if the parsed text fully includes core fields such as project name, financing amount, and affiliated region, with no obvious information missing.
- Batch import 3 to 5 daily report documents from different sources, check if duplicate project entries exist in the parsed results, and confirm that the deduplication configuration is active.
- Trigger a knowledge base recall test, check if the returned segmented content retains the contextual connection between the project and its corresponding financing method, with no information breaks across segments.
- Call the configured HTTP tool, check if the tool execution log shows that the request was sent normally, and confirm that the parameter and authentication configurations are correct.
