Knowledge Base Retrieval and Reranking for Optical Module Research Reports

Optical module research report data comes from communications industry sell-side research reports, public technical whitepapers from optical module

What the data for this category looks like

Optical module research report data comes from communications industry sell-side research reports, public technical whitepapers from optical module manufacturers, and technical specifications released by industry standard organizations. The update schedule follows new optical module product launches, industry standard iterations, and quarterly industry chain research results, with no fixed cycle. A single research report document typically includes structured fields such as model specifications, transmission rate (unit: Gbps), operating temperature range (unit: ℃), power consumption (unit: W), application scenarios, and upstream and downstream industry chain analysis. Some documents include test data and performance comparison tables.

Constraints on knowledge base retrieval and reranking

The large number of structured parameter fields with fixed units requires precise matching of parameter names and units during retrieval, to avoid recall bias caused by semantic ambiguity. Non-fixed update cycles require configuration of an incremental update mechanism to synchronize the latest optical module technical parameters and industry trends. Documents contain many professional tables and long paragraphs; segment processing must avoid splitting parameter groups, or critical context will be lost. Single document lengths vary widely, so parsing and retrieval logic must adapt to different lengths.

How to set configurations

Configuration ItemRecommended ValueRationale
segment_length800–1200 charactersAdapts to the average length of parameter groups and paragraphs in optical module research reports, avoiding splitting complete parameter description blocks
recall_countTop 6–8 resultsCovers parameter information across different dimensions in optical module research reports, avoiding omission of key technical details
similarity_threshold0.75–0.85Balances precise matching and recall coverage, filters irrelevant generic industry research report content
rerank_return_countTop 3–5 resultsFocuses on core parameter fragments most relevant to the query, reducing interference from redundant information
UPLOAD_FILE_MAX_SIZE200 MBAdapts to the common size of single optical module research report documents, avoiding upload failures
PARSE_FILE_TIMEOUT_SECONDS300 secondsProvides sufficient time for parsing and structured processing of long documents, avoiding timeout interruptions

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, and it is recommended to test on your own samples before finalizing settings.

Three Common Configuration Mistakes

  • Symptom: Reranked return results are empty or only return 1 result. Cause: The rerank_return_count parameter is not configured correctly, or the reranker model failed to load.
  • Symptom: Retrieval results include content unrelated to the query parameters. Cause: The similarity threshold is set too low, recalling non-precisely matched research report fragments.
  • Symptom: Parsing timeout errors trigger when uploading optical module research reports. Cause: PARSE_FILE_TIMEOUT_SECONDS is set too short, failing to adapt to the parsing needs of long documents.

How to Verify Correct Configuration

  • Upload a research report document containing optical module parameters, check that parsed segments retain complete parameter names and units.
  • Initiate a query that includes specific optical module models and parameters, verify that the number of returned recall results falls within the configured recall_count range.
  • Check system operation logs to confirm that the reranker model loads normally and returns reranked results.
  • Test batch uploading multiple optical module research reports of different lengths, confirm that the UPLOAD_FILE_MAX_SIZE limit is not triggered.
