What the data for this category looks like
Coke financial report-related data primarily comes from annual, semi-annual, and quarterly reports of listed coking enterprises, as well as industry operation briefs released by a domestic coking industry association. Update frequency: Enterprise financial reports are released quarterly and annually; industry briefs are updated monthly. In terms of document structure, coke-related content in enterprise financial reports is mostly concentrated in segments such as main business product breakdowns, production capacity and capacity descriptions, cost composition, and sales price fluctuation analysis. Some reports also include raw material procurement volume and downstream associated industry data. Fields include coke output, production capacity, unit production cost, average sales unit price, total inventory, and similar metrics. Units are mostly ten thousand tons, yuan/ton, and ten thousand yuan.
What constraints these characteristics impose on document parsing and chunking
Multi-source document types create parsing adaptation pressure. There are both editable Word-exported PDFs and scanned industry briefs, so different parsing logic must be supported. Fixed-length chunking cannot adapt to the mixed structure of coke financial reports. Structured tables need to retain cell associations, while long text analysis needs to be split by theme. Otherwise, business logic will be disrupted. The diversity of fields and units requires parsing to associate with context, to avoid binding data from different reporting periods with incorrect units. Frequently updated documents require the parsing process to have high efficiency, to avoid excessive processing time caused by unreasonable chunking rules.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Coke financial reports include structured tables and long-form analysis text. This range retains field associations and thematic integrity within a single chunk, avoiding splits that disrupt business logic |
chunk_overlap | 80–120 characters | Balances context coherence and storage efficiency, preventing loss of association between cross-chunk fields such as quarterly output and corresponding unit price |
parse_mode | auto | Automatically adapts to editable text and scanned documents, covering multiple document types including enterprise financial report PDFs and scanned industry briefs |
enable_table_parse | Enabled | Coke financial reports contain numerous product-specific output and cost tables. Enabling this preserves table structure, avoiding parsing into chaotic plain text |
PARSE_FILE_TIMEOUT_SECONDS | 180 seconds | Large financial report PDFs may include multi-page tables and OCR processing. This duration prevents task failure due to parsing timeout |
max_chunk_per_document | Determined via actual testing | Adapts to financial report documents of different sizes, avoiding exceeding system processing limits due to excessive chunk count |
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 targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Scenario: After uploading a coke industry analysis auxiliary document modified from a Java interface document to use a TXT file extension, the parsing result has no valid data. Cause: The Java interface document contains specific syntax structures and code blocks. Changing the file extension does not trigger the corresponding format parsing logic. The default TXT parsing mode cannot filter invalid code fragments, resulting in no valid business content being extracted.
- Scenario: After using chunk mode to call the pushdata API to upload coke quarterly financial reports, the system remains in the "indexing" state for an extended period. Cause: The
chunk_sizeandmax_chunk_per_documentparameters were not adjusted. The number of chunks per single document is too high, exceeding the system's parallel processing limit, resulting in indexing task backlog. - Scenario: After uploading a financial report PDF containing a coke production capacity bar chart, the parsing result does not include the data content from the chart. Cause:
enable_table_parseand the appropriate parsing mode were not enabled. Scanned charts cannot be recognized, only plain text content is extracted, and business data associated with the chart is lost.
How to confirm configurations are set correctly
- Upload a single-page test document of coke financial reports, view the parsed chunk list, and confirm each chunk contains complete business units.
- Open the parsing configuration panel, verify that
parse_modeandenable_table_parsesettings match the document type currently being processed. - Check the parsing logs, confirm there are no timeout errors or format parsing failure prompts, and that the number of chunks matches the expected scale.
- Extract content from any chunk, verify that the association between fields and units is correct.
