What this type of data looks like
Engineering consulting financial report data primarily comes from project cost ledgers, winning bid settlement reports, annual operating statements, and subcontract contracts. Data update cadence aligns with project cycles: updated immediately upon individual project settlement, and annual operating statements are updated per calendar year. Most documents mix structured tables and paragraphs, containing fields such as project number, cost breakdown, labor hours invested, material unit price, and others. Units include ten thousand yuan, labor hours, cubic meters, square meters, and additional units as needed.
What constraints do these characteristics impose on document parsing and chunking?
Most engineering consulting financial reports consist mostly of structured tables. Parsing processes must retain the link between cells and headers to prevent incorrect splitting. Fields are tightly bound to units, so chunking workflows must preserve contextual association between fields and units to avoid separating units from values. Individual documents may have many pages, so long-text chunking must avoid breaking overall project logic. Systems must also distinguish associations between main documents and subcontract attachments, to ensure full project context can be restored after chunking. Data update frequencies vary widely, so systems must support switching between incremental parsing and full parsing.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600-1200 seconds | Engineering consulting documents contain large numbers of tables and project details, leading to long parsing times. This range covers the parsing cycle of most complex documents. |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Engineering consulting financial reports often include large attachments such as subcontract contracts and scanned drawings. This value meets conventional upload requirements. |
chunk_size | 800-1200 characters | Financial report fields are tightly bound to units. This chunk length preserves contextual association for individual data entries and avoids breaking project logic. |
enable_table_parse | Enabled | Core data in engineering consulting financial reports appears as structured tables. Enabling this configuration fully preserves table structure and cell associations. |
top_k | Top 8-12 entries | Financial report analysis queries typically require linking multiple cost breakdowns and project milestones. This number of recalled entries covers information needs for most analysis scenarios. |
ocr_enable | Triggered based on document type | Some engineering consulting documents contain scanned drawings or tables embedded in images. Enabling OCR on demand avoids unnecessary parsing overhead. |
Three Common Mistakes
- Phenomenon: After uploading an engineering consulting financial report, parsing takes longer than 2 minutes and the request fails with a
408 Request Timeouterror in logs. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and the default timeout period is too short to complete parsing of complex documents containing large numbers of tables and attachments. - Phenomenon: After uploading a table-formatted financial report dataset to the knowledge base, some cost breakdown and subcontract quotation fields are empty or incomplete. Cause: The
enable_table_parseconfiguration was not enabled, or thechunk_sizesetting is too short, leading to incorrect splitting of table cells and loss of association between fields and values. - Phenomenon: After uploading an engineering consulting financial report containing embedded images or scanned content, tables and text within the images are not parsed. Cause: The
ocr_enableconfiguration was not enabled, or correct OCR model calling parameters were not configured, preventing recognition of embedded image content.
How to Verify Proper Configuration
- Upload a typical engineering consulting financial report document containing structured tables and embedded images, review the parsed chunk results, and confirm that table structures are complete and fields and units are not split apart.
- Check system runtime logs to confirm that parsing time does not exceed the threshold set by
PARSE_FILE_TIMEOUT_SECONDS, with no timeout-related error messages. - Upload a single document fragment containing an embedded image, and verify that the OCR-parsed text content matches the information in the image.
- Export the current knowledge base configuration and document data, import them to a test environment, and confirm that all chunked content, table structures, and attachment associations are fully preserved.
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, and it is recommended to test on your own samples before finalizing settings.
