What Data for This Category Looks Like
Data for specialized equipment research reports comes primarily from public reports released by industry associations, regular financial reports of publicly traded specialized equipment enterprises, and on-site survey documents from third-party mechanical equipment research institutions. Update frequency fluctuates with industry events. New content is generated when new models are launched, industry policies are issued, or quarterly financial reports are disclosed. Document structures typically include sections such as equipment model, core performance parameters, application scenarios, competitor comparisons, and price ranges. Fields include rated power, operating pressure, service life, and similar metrics. Corresponding units are mostly kW, MPa, hours, ten thousand yuan, and other standard units.
Constraints on Knowledge Base Retrieval and Recall
Field naming varies across multi-source data. For example, some documents label "rated power" as "installed power". This prevents general retrieval models from accurately matching core information. Individual research reports are lengthy and contain a large number of professional parameters. General recall logic can easily confuse core conclusions with redundant technical details, reducing retrieval accuracy. Update frequency has no fixed cycle. Full updates cannot be triggered on a fixed schedule. An incremental synchronization mechanism triggered by industry events must be supported. Parameter units vary across different documents. For example, power may be labeled in both kW and horsepower. This increases data verification costs after recall.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Adapts to the length of parameter paragraphs in specialized equipment research reports, avoiding loss of complete parameter combinations after splitting |
similarity_threshold | 0.72–0.85 | Balances recall precision and breadth, adapting to the semantic similarity range of professional terminology |
recall_top_k | Top 10 entries | Covers core conclusions from multi-source research reports, avoiding omission of cross-institution parameter comparison content |
UPLOAD_FILE_MAX_SIZE | 500 MB | Supports complete parsing of large individual industry research reports |
rerank_top_k | Top 5 entries | Performs secondary filtering on recall results to filter out non-core redundant content |
incremental_sync_trigger | Triggered by industry events | Adapts to the characteristic of irregular updates in the specialized equipment industry |
The parameter values provided on this page are common starting points for configuration setup. 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
- Phenomenon: Insufficient retrieval results, failing to cover core research report content. Cause: No incremental synchronization mechanism is configured, and only full updates are used. Newly published research reports are not included in the knowledge base.
- Phenomenon: The tool call module returns empty fields, and research report content from the knowledge base cannot be referenced. Cause: Core parameter fields in research reports are not configured as retrieval weight items. Core information is not prioritized for recall.
- Phenomenon: Partial data from uploaded table datasets is lost, resulting in incomplete content in the trained knowledge base. Cause: The field verification switch is not enabled, and parsing exceptions caused by inconsistent parameter units are not resolved.
How to Verify Proper Configuration
- Upload a single specialized equipment research report. Check if parsed chunks retain complete parameter combinations, and verify that the
chunk_sizeconfiguration matches expectations. - Initiate a retrieval test, input professional equipment parameter keywords. Verify that recall results include research report content from different sources, and adjust
similarity_thresholdto balance recall volume and relevance. - Simulate an industry event to trigger incremental synchronization. Check if newly added industry announcements are automatically synchronized to the knowledge base, and confirm that the synchronization logic adapts to industry event trigger rules.
- Call the tool call module. Verify that core parameters from research reports are included in returned results, and check that weight configurations are effective.
