What the Data for This Category Looks Like
Chemical fiber financing daily report data mainly comes from daily industry briefings released by the China Chemical Fiber Industry Association, corporate financing announcements on commodity trading platforms, and temporary announcements of listed chemical fiber companies. Documents are released as a single fixed file every morning. Most files use PDF or Excel format. The core structure of documents is structured tables, including fields such as financing entity name, affiliated chemical fiber sub-category (for example, polyester filament, polyamide chip), financing amount, financing term, fund provider type, and disbursement date. Amount units are uniformly ten thousand yuan or hundred million yuan. A single page table typically contains 3 to 10 daily financing project entries. Some documents also include text paragraphs summarizing overall industry financing conditions.
Constraints Imposed on Document Parsing and Chunking
The fixed daily update requirement means the parsing process must support fast batch processing to meet business timeliness requirements. The core content using structured tables requires parsing tools to fully retain table fields and unit information. Otherwise, key financing-related data cannot be accurately extracted. The presence of chemical fiber sub-category fields requires that all associated information for a single financing project — such as entity, category, and amount — be kept in the same chunk. This prevents information fragmentation during retrieval. Multi-page document layouts require chunking to support cross-page context continuity. This stops individual financing projects from being split across different content chunks.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Single multi-page chemical fiber financing daily reports contain multiple financing projects, and the total time required to parse structured tables and text is usually longer than that of general documents |
chunk_size | 800–1200 characters | Single financing project information in chemical fiber financing daily reports is dense. Chunks that are too long will lead to excessive irrelevant content during retrieval, while chunks that are too short will fragment project context |
chunk_overlap | 150–200 characters | Cross-page financing projects usually repeat some fields in page headers/footers. Overlapping chunks can retain key information for cross-page continuity |
enable_table_parse | Enabled | The core content of the document is structured tables. Enabling this option can fully retain field names and unit information, avoiding information loss caused by plain text splitting |
max_table_row_count | 50 rows | A single page table may contain multiple days of financing data. Limiting the number of rows per table chunk can prevent individual content chunks from becoming too large |
PARSE_SKIP_PAGE | 1–2 pages | The first two pages of most chemical fiber financing daily reports are cover pages and industry overview descriptions, and do not contain specific financing project data |
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 specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Errors
- Symptom: Data processing tasks show empty results, and search tests return no matches. Cause: The
enable_table_parseconfiguration is not enabled. Structured table content is directly split as plain text, resulting in lost field associations and structured information. - Symptom: Parsing tasks time out and fail. Cause:
PARSE_FILE_TIMEOUT_SECONDSis not adjusted to above 600 seconds. The parsing time of a single multi-page daily report exceeds the default threshold. - Symptom: Chunking results combine content across multiple projects. Cause:
chunk_overlapis set too low, so context between adjacent financing projects is not retained, orchunk_sizeis set too large, forcing cross-page content to be merged.
How to Verify Proper Configuration
- Upload a single standardized chemical fiber financing daily report PDF, check the parsed text preview, and confirm that table fields (such as financing amount, affiliated chemical fiber category) are fully displayed, and unit information is not lost.
- Run a search test, enter keywords for a specific financing entity or chemical fiber sub-category, and confirm that the returned results include the corresponding entry and complete associated information.
- Check the parsing task log, confirm that
enable_table_parseis enabled, and there are no timeout errors or format parsing exception prompts. - Split the test document into single pages, verify that the chunking results do not fragment cross-page information of the same financing project, and that overlapping content between adjacent chunks meets expectations.
