What This Category of Data Looks Like
Aerospace equipment investment research data mainly comes from public military industry research reports, official technical bulletins from model development stages, national defense and military industry standard documents, government procurement bidding announcements, and regular financial reports of listed military enterprises. Core industry reports are updated annually or semi-annually. Special model documents are released irregularly alongside development milestones. Financial report data is updated quarterly.
Document structures include structured parameter tables, long-text technical descriptions, performance analysis sections with formulas, and quantitative data fields marked with professional units. Fields and units include thrust (kilonewtons), orbital inclination (degrees), launch window (days), payload mass (kilograms), and other aerospace-specific metrological standards.
What Constraints Do These Characteristics Impose on the "Document Parsing and Chunking" Link
Structured parameter tables in aerospace equipment investment research documents often have merged cells. Parsing must accurately identify table structures to avoid field misalignment.
Long-text technical descriptions are tightly bound to quantitative parameters. Chunking must retain the contextual association between parameters and descriptions, without breaking technical logic.
Accurate retention of professional units directly affects the credibility of investment research data. Parsing must avoid automatic unit conversion errors.
Irregularly released special documents have diverse formats. The system must support bulk upload of files in different formats, and processing time must adapt to the parsing needs of long documents.
How to Configure the System
| Configuration Item | Recommended Range | Rationale |
|---|---|---|
maxChunkSize | 1000–1500 characters | Aerospace equipment documents contain a large number of technical parameters bound with descriptions. This range avoids separating parameters from their context while controlling retrieval redundancy |
chunkOverlap | 150–200 characters | Retains technical description text before and after parameters, ensuring complete technical logic can be associated after chunking |
PARSE_TABLE_STRICT_MODE | Enabled | Adapts to parameter tables with multiple headers and merged cells in aerospace equipment documents, avoiding field identification misalignment |
UPLOAD_FILE_MAX_SIZE | 500 MB | Supports uploading large-volume files such as complete model development reports and large-scale test data documents |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Long document parsing requires a longer processing cycle to avoid task interruption due to timeout |
enableUnitRecognition | Enabled | Automatically recognizes aerospace-specific units of measurement, retaining the original data's metrological standards |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: After uploading aerospace equipment technical documents, the parsing node shows a timeout or no task response. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and the processing time for long documents exceeded the default threshold. - Phenomenon: In the parsed document chunks, parameter table fields are missing or units are lost. Cause:
PARSE_TABLE_STRICT_MODEwas not enabled. Parameter tables with merged cells were incorrectly split, and professional units were not recognized. - Phenomenon: Only some structured data in the document is captured. Cause:
maxChunkSizewas set too small, splitting complete parameter descriptions and parameter values into two chunks, leading to broken association during retrieval, so the system only returns partial matching content.
How to Confirm the Configuration Is Properly Set
- Upload a copy of an aerospace equipment research report containing multi-header parameter tables, and check if the parsed table retains all merged cell fields and units.
- View the parsing task log to confirm that the
PARSE_FILE_TIMEOUT_SECONDSparameter is active, and long documents were not interrupted due to timeout. - Test the chunked content to verify that overlapping text matching the
chunkOverlapsetting exists between adjacent chunks, ensuring technical logic is coherent. - Bulk upload aerospace equipment documents in different formats, confirming that the upload size does not exceed the
UPLOAD_FILE_MAX_SIZElimit.
