What the data for this category looks like
Optical module financial report data comes from regular reports of listed optical module enterprises, public data from third-party industry research institutions, and carrier procurement announcements. Quarterly reports are updated within 45 days after the end of each quarter. Annual reports are updated before April each year. Document structures mostly combine structured tables and text analysis. Fields include shipment volume, unit price, gross profit margin, R&D investment ratio, and more. Units include units, CNY, and percentage. Some documents contain both actual line breaks and escaped \n strings. Content mostly focuses on business performance of optical modules with different data rates.
What constraints these characteristics impose on knowledge base retrieval and reranking
Optical module financial reports have many structured fields with high precision requirements. Field matching must be distinguished from full-text matching to avoid mixing data for optical modules with different data rates. Documents contain both escaped \n and actual line breaks. Incorrect segmentation rules lead to broken paragraphs or redundant content. Data is time-sensitive with fixed update cycles. Scheduled incremental sync tasks must be configured to avoid recalling outdated quarterly shipment data. Core metrics such as unit price and gross profit margin have high correlation. Sufficient context must be retained to ensure complete analysis logic.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment length | 800–1200 characters | Structured paragraphs in optical module financial reports are mostly 500–1500 characters. Splitting this way preserves integrity of fields and context |
recall count | Top 6–8 results | Core metrics such as shipment volume and gross profit margin are scattered across different paragraphs. Sufficient related context must be covered |
similarity threshold | 0.75–0.85 | Filters general industry data to accurately match content for the optical module category and corresponding report periods |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing large financial report PDFs takes a long time. This avoids interrupting parsing due to timeout |
knowledge base incremental sync cycle | Every 30 days | Financial report data is updated quarterly. Regular sync ensures timeliness of recalled content |
maxContext | 2000–3000 characters | Retains context linking optical module revenue and downstream customer orders to improve retrieval relevance |
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
- Segmentation of the knowledge base causes field breaks. Units or numeric fields with escaped \n are split into separate fragments. The root cause is that segmentation rules are not adjusted for the coexistence of actual line breaks and escaped \n in documents. Default segmentation logic does not distinguish between actual line breaks and string escape characters.
- Calls to the knowledge base return large volumes of non-optical module general industry financial report data. Recall results do not match the target category. The root cause is that no keyword filtering for the optical module category is set, or the similarity threshold is set too low, leading to irrelevant content being recalled.
- Attempts to retrieve the knowledge base ID return an empty value, or permission errors occur when multiple accounts edit the same knowledge base. The root cause is that the public ID was not copied correctly in the knowledge base management interface, or editing permission conflicts occur because collaborative sharing mode is not enabled.
How to Confirm Proper Configuration
- Upload a test optical module financial report document. Review parsed segmentation results to confirm no field breaks or redundant fragments appear.
- Run a retrieval test. Enter target optical module category and report period keywords. Verify the number and relevance of recall results. Adjust corresponding parameters to meet requirements.
- Access the knowledge base management interface, copy the knowledge base ID and call it in the workflow. Confirm matching content is returned normally.
- Enable collaborative sharing mode, invite test accounts to access the knowledge base. Confirm multiple accounts can edit and retrieve the same knowledge base simultaneously.
