What Data for This Category Looks Like
Data sources for optoelectronics industry financing daily reports include public disclosures from industry self-regulatory organizations, financing announcements from listed and unlisted enterprises, and daily tracking reports from third-party institutions. Updates are primarily daily; some subcategory reports are updated weekly. This scenario focuses on daily-updated daily reports. Most documents are presented as tables or structured lists, with core fields including full enterprise name, financing round, financing amount, post-money valuation, investor list, and disclosure date. Field units are standardized: financing amounts use ten thousand yuan or hundred million yuan as units, and dates follow the YYYY-MM-DD standard format.
Constraints Imposed by These Characteristics on Document Parsing and Chunking
The daily update requirement means the system must support batch file processing. The number of files processed per batch must be controlled within a reasonable range to avoid excessive consumption of parsing resources. The structured table or list format requires the parsing module to accurately identify field boundaries, preventing accidental merging of financing entries from different enterprises. Fields include numeric content with units; parsing must preserve the association between values and units to avoid information loss from chunk truncation. The short-entry characteristic of combined multiple fields requires chunking to fully wrap a single financing entry, preventing key content from being split across different chunks.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800-1000 characters | Single optoelectronics financing entry information ranges from 600-900 characters. This value can fully wrap a single entry and avoid cross-entry chunking |
chunk_overlap | 120-150 characters | Preserves contextual association for key fields such as investors and financing amounts, preventing loss of associated information during cross-block retrieval |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | When a single file contains dozens of financing entries, parsing time increases with the number of entries. This value covers standard parsing durations |
batch_parse_max_files | 20 | When processing daily report files in batches, controls concurrent volume to avoid overload of the parsing queue |
parse_table_structure | true | Most daily reports are presented in table format. Enabling this parameter preserves table structure, facilitating subsequent accurate field extraction |
parse_pdf_engine | doc2x | Adapts parsing for PDF-format daily reports, avoiding parsing failures caused by recent interface changes |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: PDF-format daily report parsing returns a
parse_errorstatus code with no valid parsed content. Cause: Theparse_pdf_engineparameter is not configured asdoc2x. Using the default parsing engine fails to adapt to recent interface updates. - Phenomenon: After batch uploading multiple daily report files, parsing results cannot distinguish file sources. Cause: The
add_file_source_metaparameter is not enabled, and no independent source identification metadata is added for each parsed file. - Phenomenon: Knowledge base search tests fail to hit target financing entries. Cause:
chunk_overlapis set too small. Key fields such as investors and financing amounts are truncated at chunk edges and not covered by indexing.
How to Verify Proper Configuration
- Upload a single test optoelectronics financing daily report file. Check the parsed chunk content to confirm each chunk contains complete single financing entry information, with no cross-enterprise entry merging.
- Call the parsing interface to verify single-file parsing duration, confirming the duration does not exceed the configured
PARSE_FILE_TIMEOUT_SECONDSthreshold. - Batch upload multiple daily report files. Check the parsing results for each file to confirm all carry independent source identification fields.
- Perform a knowledge base search test. Enter keywords from investors or financing amounts in a single financing entry to confirm the corresponding chunk content can be hit.
