What the Data for This Category Looks Like
The data sources for optical and optoelectronics industry research reports include internal broker documents, intranet statistics from industry associations, periodic reports of listed companies, and public supply chain data. Update cycles fall into three categories: quarterly financial reports, monthly industry updates, and weekly price monitoring. Most documents use mixed formats, including structured supply and demand tables, technical parameter paragraphs, and patent details. Fields include exclusive units such as nanometers (nm), candelas per square meter (cd/㎡), milliampere-hours (mAh), and others.
Constraints on Document Parsing and Chunking
This category of research reports includes both publicly accessible online content and a large volume of restricted resources stored on enterprise intranets. This creates a need for parsing adaptation for both intranet and external networks. The length of individual documents varies significantly, ranging from hundreds to over a thousand pages. Structured tables and technical parameter paragraphs appear frequently. Exclusive units and fields for specific subcategories may conflict with general parsing rules, requiring targeted calibration of recognition logic. Additionally, structured Excel data with tens of thousands of rows accounts for a high share. The chunking process must avoid overloading individual chunks to ensure the accuracy of subsequent retrieval and question answering.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
ENABLE_INTRANET_PARSE | Enabled | A large volume of optical and optoelectronics industry research reports is stored in enterprise intranet document systems, so intranet parsing adaptation must be enabled |
CHUNK_SIZE | 800–1200 characters | This category of research reports balances long technical paragraphs and structured tables. This range balances context completeness and chunk granularity |
EXCEL_PARSE_STRATEGY | Split by row while retaining headers | Most Excel source data for this category is structured data with headers plus tens of thousands of rows. Splitting by row avoids overloading individual chunks |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing thousand-page annual reports requires a longer timeout window to prevent mid-process interruptions |
ENABLE_FIELD_AWARE_PARSE | Enabled | This category includes exclusive units and technical fields. Rule matching must be enabled to prevent parsing misalignment |
MAX_CHUNK_OVERLAP | 10–15% | Long technical paragraphs require retained context to avoid semantic breaks following chunking |
The parameter values provided on this page are common starting points for configuration setup. 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 Misconfigurations
- Symptom: Intranet Confluence pages fail to extract valid content, returning empty text or parsing failure logs. Cause: Intranet parsing adaptation configuration is not enabled, or access permissions for the enterprise intranet document system are not configured.
- Symptom: Parsing tasks for 500 to 1000-page PDF annual reports time out and terminate. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. The default short timeout value cannot cover the time required for complete parsing of long documents. - Symptom: After parsing structured Excel data with tens of thousands of rows, chunk size becomes too large, triggering incomplete request prompts from large language models. Cause: The
EXCEL_PARSE_STRATEGYis not configured to split by row while retaining headers. The default full-table merge causes individual chunks to exceed reasonable size limits.
How to Verify Proper Configuration
- Upload a copy of an optical and optoelectronics industry research report stored on the enterprise intranet, and verify that the parsed text fully extracts the core structured tables and technical parameters from the original document.
- Upload a copy of a thousand-page PDF annual report, and confirm that the parsing task does not time out and terminate, and that the number of generated chunks matches the content density of the document.
- Upload a copy of Excel source data containing tens of thousands of rows, and check that individual chunk sizes after parsing do not exceed reasonable limits, with no oversized chunks created by full-table merging.
- Review parsing logs, and confirm that exclusive units and technical fields for optical and optoelectronics industries have been identified, with no field misalignment or omissions.
