What the Data for This Category Looks Like
Data sources for ordnance equipment intelligent due diligence include publicly disclosed military equipment formal approval announcements, annual reports of military industry groups, technical achievement documents from research institutes, and equipment dynamic information released by industry associations. Data update frequencies fall into two categories: irregular (when new equipment formal approval or fielding announcements are released) and annual (when annual reports are updated). Document structures include equipment model, technical parameter entries, production entity information, fielding time nodes, and performance test reports. Fields include equipment number, formal approval year, maximum range, rate of fire, protection level, and others. Some parameters include standardized units.
Constraints on Vector Models and Indexing
Ordnance equipment data contains a large number of professional technical terms and structured parameters with units. This requires vector models to have professional semantic encoding capabilities to prevent term confusion. Document lengths vary widely, ranging from short parameter entries of tens of characters to long test reports of thousands of characters. This necessitates adaptive text chunking for different text lengths. Data updates have both irregular and periodic characteristics, so both incremental indexing and full synchronization efficiency must be balanced. Some fields have strong associated attributes, such as equipment model and corresponding performance parameters. Indexing must retain these associations to avoid semantic fragmentation.
Configuration Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
embedding_model | Local open-source model (such as M3E-base, bge-large-zh-v1.5) or compliant commercial embedding API | There are many professional terms in ordnance equipment. Local models can optimize professional semantic encoding while meeting data security requirements |
chunk_size | 800–1200 characters | Balances semantic integrity for both short parameter entries and long test reports. Avoids excessive length causing context truncation, and excessive short length breaking the association of professional terms |
chunk_overlap | 100–150 characters | Retains the association of professional terms between adjacent chunks, avoiding indexing fragmentation |
recall_top_k | Top 8–12 results | Ordnance equipment due diligence requires covering multi-dimensional parameters. Too many results will introduce irrelevant information, while too few will miss key items |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing time of long test reports, avoiding indexing task interruptions caused by overly long documents |
embedding_batch_size | 16–32 entries | Adapts to video memory limits for local deployments, avoiding timeouts during batch processing |
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 specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: The embedding API call returns a 503 status code. Cause: No group routing is configured, or the default group has insufficient resources. The embedding request volume for ordnance equipment due diligence increases with new equipment announcements, and the default group cannot handle peak traffic.
- Phenomenon: Index tasks remain in a running state with no results under Docker deployment. Cause: Long text chunking for ordnance equipment documents is not adapted. Setting
chunk_sizetoo large causes parsing timeouts, orPARSE_FILE_TIMEOUT_SECONDSis not configured with a reasonable duration. - Phenomenon: Significant matching discrepancies for technical parameters in recall results. Cause: Parameter unit fields are not retained for vector encoding, leading to incorrect association of equipment of the same model with different ranges.
How to Confirm Proper Configuration
- Check the embedding model call logs to confirm that the returned vector dimensions match the configured model dimensions.
- Upload a typical ordnance equipment technical parameter document, check the indexing completion status, and confirm that the time consumption meets expectations.
- Retrieve the parameters of a specified equipment model, and verify that the fields included in the recall results match the original document.
- Simulate peak requests, check that all interface return status codes are 200, with no abnormal errors.
