What the data for this category looks like
Data for tourist attraction financing daily reports comes primarily from financing record announcements released by cultural and tourism authorities, credit approval documents from cooperating financial institutions, financing submission documents submitted by attractions, and internal operation ledgers. Updates are released every workday. Single-day document volume ranges from a few pages to dozens of pages. Document formats include three main types: official PDF announcements, Excel operation ledgers, and Word project submission documents. Core fields include attraction name, financing project name, financing amount (unit: ten thousand yuan or hundred million yuan), financing method, cooperating institution, approval date, and fund arrival date. Some documents include supplementary auxiliary data such as passenger flow and revenue.
Constraints on document parsing and chunking
Mixed document formats require the parsing module to support PDF text extraction, Excel table structured parsing, and Word style recognition simultaneously. Some Excel documents contain merged cells, which increases the difficulty of aligning table fields. Documents where core fields and auxiliary operation data are mixed require distinguishing core financing information from associated passenger flow and revenue data during chunking, to avoid mixing cross-category information. Daily document volume fluctuates greatly, so the system must support concurrent processing for batch parsing. Chunking must also retain the chronological order within documents to ensure logical coherence of financing updates. Some documents have financing amount fields with inconsistent units. Unit standardization conversion must be completed during the parsing stage to avoid unit confusion in subsequent retrieval.
How to configure the system
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
maxChunkSize | 800–1200 characters | Adapts to the chunking needs of long text paragraphs and structured tables in financing daily reports, avoiding overloading single chunks |
chunkOverlap | 100–150 characters | Retains contextual association between chunks, ensuring financing timelines and project-related information are not truncated |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Addresses parsing time for large-volume financing submission documents, preventing task timeouts and failures |
enableExcelMergeCellParse | Enabled | Adapts to merged cell formats common in attraction ledgers, enabling complete extraction of table fields |
enableUnitNormalization | Enabled | Unifies the unit format of financing amounts, converting ten thousand yuan and hundred million yuan to standard units |
batchParseMaxCount | 20 per batch | Adapts to batch document processing needs for daily updates, balancing concurrent load and parsing efficiency |
The parameter values provided on this page are common 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 configuration mistakes
- Phenomenon: Parsing tasks return a "task timeout" status code, or parsing progress gets stuck at 90% with no further updates. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and parsing time for large-volume financing submission documents exceeds the default threshold. - Phenomenon: After uploading an Excel-format attraction financing ledger, only some table fields are captured, and content within merged cells is lost. Cause: The
enableExcelMergeCellParseconfiguration was not enabled, so the merged cell structure within the document cannot be recognized. - Phenomenon: Parsed chunked content mixes financing amounts and passenger flow data, and units are not unified. Cause: The
enableUnitNormalizationconfiguration was not enabled, and no contextual association rules were set during chunking, leading to failure to correctly distinguish cross-category information.
How to confirm configurations are set correctly
- Upload a single large-volume financing submission document, check the parsing task duration, and confirm the duration falls within the threshold set by
PARSE_FILE_TIMEOUT_SECONDS. - Upload an Excel financing ledger with merged cells, verify that the parsed table fields fully cover the original document content.
- Upload a document with financing amounts in different units, confirm that the amount units in the parsed fields have been unified to standard format.
- Review the chunked text content, confirm that overlapping contextual segments exist between adjacent chunks, and that core financing information and auxiliary operation data belong to separate chunks.
