What the Data for This Category Looks Like
The data for aerospace equipment intelligent due diligence reports primarily comes from model project initiation documents, supporting supplier qualification files, ground test and inspection reports, and industry compliance standard documents from national defense and military industrial research and development units. The data update rhythm adjusts with model project initiation and finalization milestones, with no fixed cycle. Most documents use multi-chapter structured formats, including technical fields such as thrust, orbital altitude, launch window, and warranty period. Units cover professional measurement standards including kilonewtons, kilometers, seconds, and years. Some appendices contain long-sequence original test data tables.
What Constraints Do These Characteristics Impose on Document Parsing and Chunking?
The structured fields in aerospace equipment documents are mostly professional technical parameters, with a large number of cross-chapter associated test data and a high proportion of long-sequence tables. This causes general parsing tools to easily experience field misalignment. The non-fixed document structure requires parsing rules to adapt to the chapter arrangement differences of different models. Long-sequence original data tables have large single-page content. If chunking parameters are set incorrectly, data truncation or cross-chunk association breaks may occur. Some compliance description paragraphs are scattered at the end of the document. It is necessary to ensure that chunking covers complete compliance basis fragments to avoid missing due diligence information.
How to Configure
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Aerospace equipment documents often contain long-sequence test data, with longer parsing times than general documents. 300 seconds covers the parsing process for most large-volume files |
maxChunkSize | 800–1200 characters | Adapts to the length of professional technical paragraphs in aerospace equipment documents, avoiding truncation of a single complete test data set into multiple chunks |
chunkOverlap | 100–150 characters | Retains associated context for cross-chapter technical parameters, preventing loss of correspondence between fields after chunking |
CUSTOM_PARSE_SERVICE_URL | Fill in according to the self-developed structured parsing interface | Adapts to the professional table parsing needs of aerospace equipment documents, replacing the default general parsing logic |
PARSE_TABLE_MAX_ROWS | 500 rows | Supports complete parsing of long-sequence test data tables, avoiding automatic truncation of table content |
SIMILARITY_THRESHOLD | 0.75 | Filters low-correlation due diligence document fragments, ensuring recalled content is strongly associated with aerospace equipment technical parameters |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on available sample sets before finalizing settings.
Three Common Mistakes
- Symptom: A
504 Gateway Timeouterror is returned after uploading an aerospace equipment document, or parsing progress stalls. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted. The default timeout duration is insufficient for parsing large-volume documents containing long-sequence test data. - Symptom: After importing a CSV qualification table from an aerospace equipment supporting supplier, only the first two columns of data are read. Cause: The
PARSE_TABLE_MAX_ROWSparameter was not adjusted, or the default table parsing rules do not adapt to the multi-column professional parameter format. - Symptom: Technical parameters and their corresponding test data are separated in the chunked content. Cause: The
chunkOverlapparameter value is too low, failing to retain cross-chunk context association information.
How to Verify Proper Configuration
- A single aerospace equipment document containing a long-sequence test table is uploaded, and the parsed text is checked for full coverage of all table rows and columns.
- After configuring the custom parsing service, a test document is uploaded, and the parsed result is checked for retention of the structured format of professional technical fields.
- After adjusting the
maxChunkSizeandchunkOverlapparameters, the chunked content is checked for absence of truncation of a single test data set. - Parsing logs are reviewed to confirm that the
PARSE_FILE_TIMEOUT_SECONDSparameter is in effect, with no timeout error records.
