What the data for this category looks like
Marketing documents for aerospace equipment mainly come from publicly available model development materials, ground test reports, official product brochures, and performance parameter datasets in padans format. Update cycles adjust dynamically with model project initiation, test milestones, and new product launches. Document structures include long-form technical description PDFs, structured parameter tables, technical description pages with diagrams. Fields cover parameters with strict physical units such as thrust, specific impulse, orbital inclination, and more. Some documents embed fragments of HTTP interface response messages and image annotations.
What constraints these characteristics impose on document parsing and chunking
Long-form technical documents can produce individual chunks that are too long or too short, which disrupts contextual association of key parameters and operating conditions. Structured parameter data in padans format must retain table structures to avoid losing parameter correspondence after conversion to plain text. Documents with embedded HTTP response fragments must parse the Set-Cookie field to ensure subsequent session association operations work correctly. Pages with diagrams must link images to their corresponding text descriptions to prevent semantic disconnection. Parameters have strict physical units. Chunking must retain the binding relationship between parameters and units to avoid errors where parameters are separated from their units.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxChunkSize | 800–1200 characters | Adapts to long parameter paragraphs and technical descriptions in aerospace equipment documents, avoiding broken associations of key parameters in single chunks |
chunkOverlap | 150–200 characters | Retains contextual continuity between chunks, ensuring the binding relationship between parameters and operating conditions is not lost |
PARSE_TABLE_ENABLE | Enabled | Preserves the structured parameter table structure of padans format data, preventing semantic loss during plain text conversion |
PARSE_HTTP_SET_COOKIE | Enabled | Parses the Set-Cookie field embedded in HTTP response fragments within documents, supporting subsequent session association operations |
PARSE_IMAGE_OCR | Enabled | Recognizes technical diagrams and annotated text embedded in documents, linking images to their corresponding descriptive content |
PARSE_TIMEOUT | 600 seconds | Matches the parsing duration of long-form test reports and large PDF documents, preventing timeout interruptions |
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 individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: padans format data is parsed as plain text paragraphs without complete table structures. Cause: The
PARSE_TABLE_ENABLEconfiguration is not enabled, leading to flat processing of structured data. - Phenomenon: After a knowledge base is created, parsing status updates cannot be retrieved, making it impossible to determine parsing in progress, ready, or failed states. Cause: The knowledge base parsing status query interface is not called, or the parsing callback notification mechanism is not configured.
- Phenomenon: The Set-Cookie field embedded in documents is not extracted, preventing subsequent associated requests from reusing sessions. Cause: The
PARSE_HTTP_SET_COOKIEconfiguration is not enabled, ignoring session fields in HTTP response fragments.
How to confirm configurations are correctly set
- Upload a single padans format parameter document, check if the parsed content retains the table structure, and confirm the binding relationship between parameters and their corresponding units.
- Call the knowledge base parsing status query interface to verify that real-time status feedback for parsing in progress, ready, and failed states can be obtained.
- Upload a document containing HTTP response fragments, check if the parsed result includes extracted content from the Set-Cookie field.
- Upload a PDF document with embedded images, confirm that the parsed result links images to their corresponding text descriptions.
