What Data for This Category Looks Like
Optoelectronics industry research report data mainly comes from industry associations, securities firm research institutes and third-party consulting institutions. Update cycles fall into two categories: industry dynamic reports are updated weekly or biweekly, while in-depth technical reports are updated monthly or quarterly. Document structures include core technical parameter tables, corporate revenue breakdowns, industry policy interpretations and segmented category analyses. Fields cover product model, brightness, power consumption, production capacity, revenue amount and other items. Units include cd/㎡, mA, inches, 10,000 yuan/ton and other professional measurement standards.
What Constraints Do These Characteristics Impose on the Knowledge Base Retrieval and Recall Link
Decentralized data sources require retrieval systems to support unified format import and field alignment for multi-source documents. High-frequency update cycles require incremental sync tasks to adapt to short update cycles, avoiding resource consumption from full synchronization. Large volumes of structured technical parameters and long professional paragraphs in documents require vector models to adapt to embedding effects for Chinese long texts and structured data. Multiple fields and professional units require preprocessing steps to complete unit standardization and entity abbreviation alignment. Otherwise, recall results will have unit confusion or entity mismatch issues.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
embedding_model | shaw/dmeta-embedding-zh | Adapts to embedding requirements for Chinese long texts and structured technical parameters, matching the professional content characteristics of optoelectronics industry research reports |
chunk_size | 800–1200 characters | Balances segmentation granularity and context integrity, avoiding truncation of core technical parameters and key content after table splitting |
recall_top_k | Top 8–12 results | Covers scattered technical points and data correlations in optoelectronics industry research reports, avoiding omission of key matching content |
rerank_top_k | Top 3–5 results | Filters redundant recall results, focusing on core research report fragments highly relevant to the query |
incremental_update_interval | 7 days | Adapts to the weekly update cycle of industry dynamic research reports, balancing data freshness and synchronization resource consumption |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the long content parsing requirements of single in-depth research reports, avoiding parsing timeouts due to overly long content |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to run tests on local datasets before finalizing.
Three Common Misconfigurations
- Phenomenon: Generated answers only summarize core conclusions, without citing specific clauses or technical parameters from research reports. Cause: The
chunk_overlapparameter is set too small, leading to loss of context fragments where clauses are located during segmentation. - Phenomenon: Knowledge base retrieval takes more than 30 seconds, and the interface shows loading delays. Cause: The
recall_top_ksetting exceeds 15 entries, and the reranking link is not enabled, leading to a large number of irrelevant documents entering subsequent processing flows. - Phenomenon: Inconsistent units for the same parameter appear in retrieval results, for example, brightness is shown as both cd/㎡ and nit. Cause: No field standardization preprocessing rules are configured, and professional measurement units in research reports are not unified.
How to Confirm Proper Configuration
- Upload a single in-depth research report, check the parsed segmented content, confirm that core technical parameters and table data are not truncated.
- Initiate a query containing specific technical parameters, check that the number of recall results matches the
recall_top_ksetting. - Run the incremental sync task, confirm that only research report documents published in the last 7 days are updated.
- Check the vector model running logs, confirm that no embedding timeout or format error prompts appear.
