What the data for this category looks like
Aerospace equipment category financial report data mainly comes from annual reports, semi-annual reports and temporary public disclosures of domestic and overseas military industry listed companies. It also includes industrial research reports released by industry associations. Updates follow a fixed annual and semi-annual rhythm, with irregular updates accompanying major project signings, capacity adjustments and other events. Document structures include standard financial fields, as well as aerospace-specific content such as launch vehicle launch counts, on-orbit satellite counts, core component production capacity. Field units involve professional measurement standards such as units, pieces, kilograms, ten thousand yuan. Some technical parameters have exclusive industry definitions.
Constraints on document parsing and chunking
The mixed fixed and irregular data update rhythm requires the document parsing module to support both scheduled batch parsing and temporary upload parsing modes. Aerospace equipment financial reports contain a large number of exclusive technical paragraphs and professional terms. Chunking must avoid splitting core technical descriptions and associated parameters to prevent professional information from being disrupted. Documents mix standard financial fields and aerospace-specific measurement units. The parsing process must retain the binding relationship between values and their corresponding units. Some temporary announcements have non-standard formatting. The system must support multi-format input and automatically correct minor formatting errors to ensure logical coherence of content after chunking.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single documents for aerospace equipment financial reports may include hundreds of pages of project details, requiring support for large file uploads |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long documents require processing large numbers of tables and technical charts, leading to longer parsing times |
chunk_size | 1200–1500 characters | Adapt to longer technical paragraphs in aerospace financial reports to avoid splitting core professional descriptions |
chunk_overlap | 100–150 characters | Retain contextual associations across chunks to ensure coherence between professional terms and associated parameters |
enable_ocr | Enabled | Some aerospace equipment financial reports are released as scanned documents, requiring OCR to recognize text content |
filter_special_chars | Disabled | Retain aerospace-specific symbols and unit formats to avoid damaging the integrity of professional information |
The parameter values provided on this page are general recommendations used as a starting point for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: File upload via the dialog box shows no parsing progress, and no error logs are generated in the background. Cause: The
enable_ocrconfiguration is not enabled. Scanned aerospace equipment financial reports cannot be directly recognized and parsed. - Symptom: System memory usage rises abnormally after enabling the parsing function, and service restarts may be triggered. Cause: The
UPLOAD_FILE_MAX_SIZElimit is not set. Ultra-large aerospace financial report documents exceed the system memory allocation threshold. - Symptom: Core technical parameter content is missing from knowledge base chunks after uploading files via the API. Cause: The
chunk_sizeparameter is not configured to a range adapted to long paragraphs, which breaks the binding between technical descriptions and associated values.
How to confirm the configuration is correct
- Upload a scanned copy of an aerospace equipment financial report, check if the parsed text content includes complete information such as launch counts and production capacity data, to confirm the OCR configuration is correct.
- View the running logs of parsing tasks to confirm that parsing time does not trigger timeout alerts, verifying that the timeout setting matches the actual duration required for document processing.
- Export the chunking results of a single document, check that values and their corresponding measurement units in each chunk are not split, confirming that the chunking parameters are adapted to the length of professional paragraphs.
- Call the batch upload interface to submit multiple financial report files, confirm that all tasks normally enter the parsing queue, verifying that the file size limit configuration is reasonable.
