What Data for This Category Looks Like
Semiconductor industry financial report data mainly comes from periodic reports publicly disclosed by domestic and overseas stock exchanges, and special announcements released on the investor relations sections of listed companies. Update schedules follow regulatory requirements: quarterly reports are disclosed within one month after the end of the quarter, and annual reports are disclosed within four months after the end of the year. Document structures typically include fields such as wafer shipment volume, capacity utilization rate, R&D investment ratio, and segmented business revenue. Units involve ten thousand pieces, hundred million yuan, percentage, and other units. Some special reports also include technical-related data such as process nodes and yield rates.
What Constraints Do These Characteristics Impose on the Document Parsing and Chunking Stage?
Technical fields and financial fields in semiconductor financial reports are mixed. Parsing requires precise distinction between technical parameters such as process nodes and yield rates, and financial data such as revenue and gross margin. This avoids breaking semantic associations during chunking. Single report length varies widely, from dozens of pages of quarterly briefings to hundreds of pages of annual reports. This requires adapting to the segmentation boundaries of long texts. Units are mixed within documents: wafer shipment volume uses ten thousand pieces as the unit, while revenue uses hundred million yuan as the unit. Chunking must retain unit context to maintain data accuracy. Some special reports use non-standard table formats. This requires identifying field associations within tables to avoid losing business logic during splitting.
How to Set the Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Semiconductor financial reports contain a large number of structured tables, and table fields and business data need to be parsed and extracted |
CHUNK_SIZE | 800–1200 characters | Semiconductor financial reports include long technical descriptions and financial data. This range preserves the integrity of a single business logic |
CHUNK_OVERLAP | 100–150 characters | Prevents critical context from breaking after segmentation, especially for cross-segment technical parameter associations |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large annual financial reports take longer to parse, and this setting adapts to the parsing duration of long documents |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Some annual financial report PDFs can reach hundreds of megabytes in size, and this setting adapts to large file uploads |
SIMILARITY_THRESHOLD | 0.65–0.75 | Technical and financial fields in semiconductor financial reports are closely associated, and this range filters low-similarity irrelevant 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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: After uploading some semiconductor financial report PDFs, the parsing result shows empty content, and the console returns a
413 Request Entity Too Largeerror. Cause: TheUPLOAD_FILE_MAX_SIZEparameter is not adjusted, and the file volume exceeds the platform's default limit. - Phenomenon: Search tests return empty results, or only a small number of irrelevant contents. Cause: The
PARSE_TABLE_ENABLEparameter is not enabled, and structured table data in the financial report is not extracted, resulting in missing core business fields in the chunks. - Phenomenon: Chunking logic is chaotic after parsing, and technical parameters and financial data are split into different chunks. Cause: The
CHUNK_SIZEvalue is too small, which destroys the integrity of a single business logic, or no reasonableCHUNK_OVERLAPparameter is set, leading to context breakage.
How to Confirm the Configuration Is Correct
- Upload a standard quarterly financial report PDF, check the parsing progress prompt, and confirm that the parsing task does not time out.
- Enter the chunk management page of the knowledge base, view the generated chunk content, and confirm that core fields such as wafer shipment volume and R&D investment are included.
- Run a search test, enter keywords related to semiconductor business, and check if the returned chunks contain corresponding data.
- Check the parsing log, confirm that the table parsing switch is activated, and no prompts for lost table content appear.
