What the data for this category looks like
Optical module-related financial report data mainly comes from periodic reports disclosed by domestic and overseas stock exchanges, and public research documents from industry associations. The update cycle follows quarterly and annual schedules, matching the release dates of listed companies’ quarterly and annual reports. Most documents are in PDF format, and include structured financial statements and business segment data. Core fields include optical module business revenue, shipment volume, average module price, and raw material cost ratio. Units include RMB 10,000 yuan, 10,000 units, USD per unit, and others. Some overseas reports use local currency for valuation.
What constraints do these characteristics impose on document parsing and chunking
The characteristics of optical module financial reports impose multiple constraints on document parsing and chunking. First, document size varies widely. The page counts of quarterly and annual reports differ significantly. It is recommended to use statistics from your own samples or conduct tests to determine parsing and chunking logic for different document lengths. Second, content mixes structured tables and unstructured business analysis. Optical module business data is often embedded in segment report paragraphs. The association between fields and context must be retained to avoid separating core data from business descriptions after chunking. Third, valuation units differ between domestic and overseas reports. Unit association information must be retained during chunking to prevent misalignment between values and units. Fourth, report release dates are concentrated. The parsing process must maintain stability for batch upload scenarios.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Optical module financial reports have many pages and high content density. 600 seconds covers parsing needs for most annual reports |
chunk_size | 800–1200 characters | Financial reports include business analysis and structured tables. This range retains the association between optical module business data and context |
chunk_overlap | 150–200 characters | Optical module-related business descriptions often span paragraphs. The overlap range ensures continuity of cross-paragraph logic |
PARSE_TABLE_ENABLED | Enabled | Core data such as optical module revenue and shipment volume is presented in table form. Enabling this setting allows complete extraction of structured fields |
PARSE_MULTIPAGE_TABLE | Enabled | Large financial reports may have optical module business tables split across pages. Enabling this setting merges cross-page table content |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Annual financial report PDFs can exceed 500 MB. This upper limit covers batch upload scenarios |
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
- Phenomenon: When calling the knowledge base creation API, only the initial submission status is returned. Real-time update statuses such as parsing in progress, ready, or parsing failed cannot be obtained. Reason: Parsing status push configuration is not enabled. The default interface only returns submission results and does not synchronize backend parsing progress.
- Phenomenon: In parsed optical module financial report data, domestic and overseas valuation units are not correctly associated, resulting in separate value chunk content. Reason: Multi-language unit recognition configuration is not enabled. Only domestic RMB valuation fields are adapted by default.
- Phenomenon: After uploading an optical module financial report PDF, cross-page tables in the parsing result are split into multiple scattered fragments. Reason:
PARSE_MULTIPAGE_TABLEconfiguration is not enabled. Cross-page table content is not merged.
How to confirm the configuration is set correctly
- Upload a quarterly optical module financial report PDF, and check the integrity of the parsed table content to verify if the table parsing configuration takes effect.
- Upload an annual financial report PDF containing cross-page optical module business tables, and check if cross-page tables are merged into complete entries to verify if the cross-page table configuration takes effect.
- Call the knowledge base creation interface, and confirm that the returned result includes fields related to parsing progress to verify if the parsing status synchronization configuration is enabled.
- Upload the same financial report and adjust the chunk length parameter. Compare chunk results under different configurations to confirm that the chunking logic adapts to the content structure of optical module financial reports.
