Knowledge Base Retrieval and Recall for Aerospace Equipment

What Data for This Category Looks Like

Aerospace equipment category financial report data primarily comes from periodic reports of listed companies disclosed by domestic and overseas stock exchanges, and publicly available statistical materials from industry associations. Updates follow a quarterly cadence, paired with full semi-annual and annual financial report releases. Document structures follow fixed disclosure formats, including fields such as core financial indicators, on-hand orders, delivery sorties, revenue breakdown segment proportions, and more. Units are mostly ten thousand yuan, sorties, and sets/units; some segmented data is labeled by aircraft model.

Constraints Imposed on Knowledge Base Retrieval and Recall

The large number of fixed formats and segmented fields requires precise retrieval matching of non-general financial fields such as aircraft models and delivery sorties. This avoids generic retrieval confusing similar indicators. The quarterly update timeliness requirement means recalled data must prioritize weighting the most recently disclosed quarterly data. Individual financial report documents are lengthy. Reasonable control of paragraph splitting granularity prevents context overflow. Differences exist in segment naming. Alias matching must be supported to cover the disclosure habits of different companies.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`recall count`	Top 8-12 results	Aerospace equipment financial reports have many segmented fields, requiring sufficient recall volume to cover data across different segments while avoiding redundant results interfering with analysis
`similarity threshold`	0.72-0.80	Segmented fields have small semantic differences, requiring a higher threshold to filter irrelevant results while retaining approximate indicators from the same segment
`chunk length`	800-1000 characters	Individual financial report paragraphs are lengthy. This chunk range balances context completeness and retrieval precision
`reranked return count`	Top 4-6 results	Must retain the most relevant segmented financial report data, avoiding excessive results dispersing analysis focus
`PARSE_FILE_TIMEOUT_SECONDS`	120 seconds	Individual financial report documents include multi-page charts and tables, requiring sufficient time for format splitting and field extraction
`UPLOAD_FILE_MAX_SIZE`	20 MB	Aerospace equipment financial report PDFs often include detailed charts, requiring a reasonable file size limit

The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on one's own samples before finalizing settings.

Three Common Mistakes

Phenomenon: No citation source displays at the end of the answer (corresponding to the feature added in version 4.9.7). Cause: The enable citation configuration item is not enabled, or the citation matching threshold is set too high, resulting in no valid sources being recalled.
Phenomenon: Knowledge imported via static pages cannot be updated automatically. Cause: No scheduled synchronization task is configured, or the synchronization trigger rule is not bound to the static page update event.
Phenomenon: Irrelevant answers appear after consecutive questions in the same window. Cause: The maxContext parameter is set too small, failing to retain the context of previous questions, or the session context reuse function is not enabled.

How to Confirm Configuration Correctness

Upload a financial report of an aerospace equipment listed company. Use the knowledge base preview function to check if parsed paragraph chunks fall within the preset chunk length range.
Submit a query that includes segmented fields. Check if the number of recall results matches the recall count configuration, and if the semantic matching degree of results meets expectations.
Test the consecutive question scenario. Confirm via session logs whether context is correctly passed, and verify that the session context reuse function is operating normally.
Enable the enable citation function. Submit a query, check if a corresponding citation identifier generates at the end of the answer, confirming that the citation function operates normally.

Question material comes from public community discussions. Configuration values are common starting points and should be measured against your own samples. Verified on 2026-09-14.
