What this category’s data looks like
Financial report data for the optical and optoelectronic industry comes primarily from official disclosure platforms of securities regulatory authorities and public reports released by the China Optical and Optoelectronic Industry Association. Updates follow quarterly, semi-annual, and annual regular disclosure cycles, with temporary announcements such as production capacity adjustments and new product launches updated simultaneously.
Documents include structured financial statements and unstructured operating explanations. Fields cover operating revenue, shipment volume, yield rate, R&D investment ratio, and more. Shipment volume units are mostly ten thousand pieces or ten thousand units. Yield rate is expressed as a percentage value. Some panel-related financial reports also include segmented fields such as display size and power parameters. Common file formats are PDF announcements and XBRL structured files.
What constraints do these characteristics impose on the citation sources and traceability link
Optical and optoelectronic industry financial reports have numerous segmented fields and high professional requirements. Traceability must accurately match field names and corresponding disclosure content to avoid confusion with financial reports from other industries.
The presence of structured XBRL files requires traceability to associate element IDs and announcement numbers, rather than relying solely on text fragment matching. The mixed update rhythm of regular and temporary disclosures means traceability systems must retain the disclosure timestamp for each data point to ensure the timeliness of cited content.
For capacity planning and technical parameter descriptions in unstructured operating explanations, precise paragraph source positioning is required to avoid field confusion across documents.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recallTopK | 10-15 | Optical and optoelectronic financial reports include segmented industry fields such as yield rate and shipment volume. Sufficient recall volume is needed to cover accurately matched documents |
similarityThreshold | 0.72-0.78 | Semantic similarity between similar fields in financial reports is high. A threshold that is too low will introduce irrelevant financial report announcements |
chunkSize | 800-1200 characters | Adapts to the length of structured financial statement paragraphs and unstructured operating explanations in optical and optoelectronic financial reports, avoiding splitting that destroys field integrity |
enableXbrlParse | enabled | Most optical and optoelectronic financial reports are disclosed in XBRL format, which can accurately extract standardized fields and associate traceability IDs |
sourceRetainCount | 3-5 | Citations for financial report analysis need to focus on core basis. Excessive traceability information will interfere with analysis logic |
maxContextWindow | 12000-15000 characters | Supports context requirements for multi-field comparison of optical and optoelectronic financial reports, avoiding truncation of key associated data |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing the configuration.
Three common configuration mistakes
- Phenomenon: The number of model context display entries does not match the actual recall entries. For example, the page shows only 30 context entries, but the actual number of recalled entries far exceeds the configured value. Cause: The
maxContextWindowparameter is not configured correctly, causing the system to automatically truncate recalled content that exceeds the window, and only display the truncated portion. - Phenomenon: When
sourceRetainCountis set to 1500, document blocks longer than 1500 characters in the knowledge base are still cited. Cause: The configuration logic ofsourceRetainCountandchunkSizeis confused.sourceRetainCountrefers to the number of retained traceability entries, and is not equivalent to the length limit of a single document block. - Phenomenon: Extracted financial report field variables cannot be called in the generated financial report analysis body. Cause: The trigger rules for variable mapping are not configured correctly, or the format requirements for variable calls are not stated in the system prompt.
How to confirm correct configuration
- Upload a public optical and optoelectronic industry financial report announcement, check the parsed field details in the knowledge base, and confirm that category-exclusive segmented fields have been extracted.
- Initiate a financial report analysis query, check the traceability module of the returned results, and confirm that each citation includes the official disclosed announcement number and timestamp.
- Adjust the recall-related configuration parameters to the target values, initiate a query, and verify that the number of recalled documents matches the configured value.
- Import financial report documents that exceed the preset single-block length limit, and confirm that the system normally processes citation requests for such documents after triggering a query.
