What This Category’s Data Looks Like

Data for aerospace equipment research reports comes primarily from securities firms’ military industry research reports, public materials from national defense and military industry associations, and publicly disclosed information from main aircraft manufacturers and supporting suppliers. Update cycles include regular quarterly and annual industry review reports, plus ad-hoc special reports issued when major models are finalized, air shows are held, or policies are released. Document structures typically include modules such as overall industry trends, core model parameters, industrial chain supporting details, market size estimates, and risk warnings. Fields include model codes, delivery cycles, production capacity scales, supporting manufacturer names, revenue estimates, and more. Units include units such as aircraft, years, and 100 million yuan.

Constraints on Knowledge Base Retrieval and Recall

The multi-source nature and irregular update cycle of aerospace equipment research reports require the knowledge base retrieval system to support incremental synchronization and rapid access to ad-hoc reports, to avoid missing updates on the latest model dynamics. Complex document structures and long lengths require that core fields such as model codes and production capacity data are fully retained during segment parsing, to avoid truncation of critical information. The need for precise matching of specific fields such as supporting manufacturers and delivery cycles requires prioritizing entity recognition-based associated recall, to avoid matching errors that occur with full-text keyword matching alone. The clear unit system for industry data requires retaining original unit annotations in recall results, to avoid confusion over parameter calibers across different models.

Configuration Settings

Configuration ItemRecommended RangeRationale
PARSE_CHUNK_SIZE800–1200 charactersAerospace equipment research reports contain long paragraphs of industry data and model parameters. This range retains the integrity of core fields and avoids truncation of critical parameters
RECALL_TOP_K8–12 entriesCore information for aerospace equipment research reports is scattered across multiple paragraphs. This range covers all industrial chain-related content while avoiding redundant results
SIMILARITY_THRESHOLD0.72–0.85Precise matching of specific entities such as model codes and delivery cycles is required. This range filters irrelevant results while retaining relevant content
UPLOAD_FILE_MAX_SIZE200 MBSingle aerospace equipment research reports may contain multiple pages of charts and detailed data. This range supports uploads of large file sizes
PARSE_FILE_TIMEOUT_SECONDS300 secondsParsing large research reports takes extended time. This range avoids parsing failures caused by premature timeout
RERANK_TOP_N3–5 entriesReranking filters redundant results from initial recall, retaining the most relevant research report fragments for user queries

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

Three Common Configuration Mistakes

  • Retrieval results only return 1 entry, failing to cover all relevant research reports. This occurs when RECALL_TOP_K is set to 1, which does not match the scattered core information characteristic of aerospace equipment research reports.
  • Knowledge base access speed is excessively slow. This occurs when UPLOAD_FILE_MAX_SIZE is set too large and incremental update is not enabled, causing excessive redundant files to be loaded during each retrieval.
  • Research report images returned in Q&A fail to render properly. This occurs when the ENABLE_PARSE_IMAGE parameter is not enabled, causing image links or embedded identifiers to not be extracted during the parsing phase.

How to Verify Proper Configuration

  • Upload a typical aerospace equipment research report, and check that parsed text segments retain core fields such as model codes and production capacity data without obvious truncation.
  • Enter precise queries such as "XX model delivery cycle", and verify that the number of recall results and similarity scores match the preset configuration.
  • Upload a research report containing images, and confirm that parsed image content can be displayed normally during Q&A.
  • Simulate batch retrieval requests, and confirm that system response has no obvious abnormal delays.
