What the Data for This Category Looks Like
Energy metals financial report data mainly comes from periodic reports of domestic and overseas stock exchanges, production capacity statistics documents from industry associations, and spot market quotation announcements. Update cycles follow quarterly reports updated every 3 months and annual reports released once per year. Temporary announcements are issued alongside industry events or corporate dynamics. The page count of single financial report PDF files varies widely. It is recommended to count or test with your own samples before finalizing any setup. Document structures include consolidated financial statements, detailed lists of proven metal reserves, smelting capacity utilization data, and more. Fields include proven reserves (unit: tons), single-quarter revenue (unit: 100 million yuan), raw material procurement costs (unit: yuan/ton), and some documents include image pages with embedded tables.
What Constraints Do These Characteristics Impose on the Document Parsing and Chunking Link
Energy metals financial reports feature multi-page embedded tables, structured numerical fields, and high density of professional terminology. These traits impose multiple constraints on the document parsing and chunking process. First, most embedded tables span multiple pages. Parsing must retain the overall table structure to avoid splitting numerical values and their corresponding descriptions. Second, single documents have a large number of pages and contain numerous associated numerical paragraphs. Chunk boundaries must avoid the middle of professional terms to prevent semantic breaks. Third, temporary announcements have a high update frequency. The parsing process must support batch rapid processing to avoid increased time consumption from redundant logic.
How to Configure the Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
parser_mode | ocr+markdown | Energy metals financial reports include a large number of image pages with embedded tables. Plain text parsing cannot extract structured data within tables. The OCR mode can restore the table structure |
chunk_size | 800–1200 characters | The average length of combined structured numerical paragraphs and industry terminology in energy metals financial reports falls within this range, which can retain the integrity of a single piece of associated information |
chunk_overlap | 100–150 characters | Cross-page tables or long terminology paragraphs may cross chunk boundaries. The overlapping portion ensures semantic coherence |
enable_table_merge | Enabled | Energy metals financial reports contain a large number of cross-page tables. Enabling this option automatically merges content from the same table across pages to avoid chunking that splits the table structure |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Single energy metals financial report PDF files have a large number of pages. OCR parsing and chunking processing require a long time. This duration covers the processing flow for most single documents |
custom_separator | [\n\n, Chapter\d+, Table\d+] | The chapter and table numbering in energy metals financial reports are natural chunk boundaries, which can accurately control the starting position of chunks |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis. It is recommended to test with your own samples before finalizing the settings.
Three Common Mistakes
- Phenomenon: After configuring
custom_separatorandchunk_size, chunking results either merge multiple independent paragraphs or split a single long text into multiple incomplete chunks. Cause: The custom separators are not accurately set for the chapter numbering and table numbering of energy metals financial reports, and thechunk_overlapparameter is not adjusted to match the semantic boundaries of long numerical paragraphs. - Phenomenon: An error is returned when processing a PDF after deployment, returning
{"detail":"Processing timed out"}or status code 500. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted to a duration suitable for the page count of energy metals financial reports, or the server memory is insufficient to support OCR parsing of multi-page PDFs. - Phenomenon: Table content in chunking results is split into multiple independent chunks, and numerical values are separated from their corresponding descriptions. Cause: The
enable_table_mergeparameter is not enabled, or theparser_modeis not set toocr+markdownmode, making it impossible to recognize the structure of embedded tables.
How to Confirm Proper Configuration
- Upload a sample energy metals financial report that includes an embedded table on a single page, and check if the parsed text fully restores all numerical values and descriptive text within the table.
- Review the text blocks of the chunking results, confirm that chapter titles and table numbers are used as chunk starting identifiers, and no chunk splitting occurs in the middle of professional terms.
- Upload multiple financial report documents of the same type in batch, and check if the parsing time meets expectations, with no timeout errors.
- Search the chunked knowledge base, confirm that associated numerical fields and their corresponding descriptive text appear in the same chunk or adjacent chunks.
