Citation Sources and Provenance for Optical Optoelectronics Intelligent Due Diligence Reports

Data sources for optical optoelectronics industry due diligence include publicly monitored reports from the China Optical Optoelectronics Industry

What Data Looks Like for This Category

Data sources for optical optoelectronics industry due diligence include publicly monitored reports from the China Optical Optoelectronics Industry Association, operating announcements disclosed by enterprises, shipment records of upstream equipment suppliers, and publicly available documents from patent offices. Update frequencies vary: industry association reports are released quarterly, enterprise operating announcements are updated alongside financial reporting cycles, patent data is synchronized in real time, and equipment shipment records are updated weekly. Document formats primarily consist of structured tables and unstructured analysis reports, with some in PDF format. Fields include wafer size, monthly production capacity, unit production cost, downstream customer proportion, and more. Production capacity is measured in thousands of wafers per month, production cost in yuan per wafer, and wafer size in inches.

Constraints on Citation Sources and Provenance

The multi-source dispersion and varying update frequencies of optical optoelectronics industry data require the provenance process to bind corresponding update timestamps to each data type, and filter expired cited content. The coexistence of structured tables and unstructured analysis reports requires adapting two sets of parsing rules to avoid misalignment of field extraction. Precision parameter fields are tightly bound to their units, so both the field name and unit identifier must be matched during provenance to prevent distortion of cited parameters. Patent sources must be associated with application numbers as unique provenance identifiers, ensuring cited patent documents can be accurately traced back to their original public pages.

Configuration Settings

Configuration ItemRecommended SettingRationale
PARSE_FILE_TIMEOUT_SECONDS900 secondsOptical optoelectronics industry reports often contain multi-page tables and long text, extending the parsing timeout prevents interruptions during large file parsing
chunk_size1000–1500 charactersOptical optoelectronics parameter content mostly consists of compact field combinations, this segment length preserves the association between parameters and context, avoiding field breakage after splitting
recall_top_kTop 8 entriesOptical optoelectronics due diligence requires covering multi-dimensional data including production capacity, cost, and customers, recalling 8 entries covers core information sources
similarity_threshold0.75–0.85Semantic matching for precision parameters requires a high threshold to avoid recalling low-relevance general industry documents
source_id_mapping_fieldpatent_application_id, industry_report_idOptical optoelectronics data includes two core source types: patents and industry reports, requiring binding corresponding unique identifier fields by source type
UPLOAD_FILE_MAX_SIZE500 MBLarge industry analysis reports and patent collections often exceed standard sizes, adjusting the upload limit adapts to the needs of this category

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 case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.

Three Common Mistakes

  • Phenomenon: Unrendered Markdown syntax symbols such as #, ** appear in the context citation area, and formats cannot be displayed normally. Cause: The Markdown format retention configuration during document parsing is not enabled, causing format markers to be retained as plain text.
  • Phenomenon: A source_id not found error occurs during provenance, and the unique identifier of the corresponding data source cannot be associated. Cause: The category-specific unique field was not correctly extracted and bound when uploading the file, resulting in failure to complete the source identifier mapping.
  • Phenomenon: The number of recalled citations exceeds expectations, including a large amount of general industry content unrelated to the optical optoelectronics category. Cause: A reasonable similarity threshold was not set, causing non-specialized documents with low matching degrees to be mistakenly recalled.

How to Verify Correct Configuration

  • Upload an optical optoelectronics industry report, check the parsed segmented content, and confirm that parameter fields and context are not split and broken.
  • Initiate a due diligence query, check the returned citation source list, and verify that each source is bound to the category-specific unique identifier field.
  • Check the format display of cited content, and confirm that Markdown syntax has been properly rendered.
  • Adjust the recall-related configuration and initiate a duplicate query to verify whether the number of citations and matching degrees meet preset requirements.
