What the data for this category looks like
Specialized equipment research report data comes from public reports from financial industry associations, regular announcements from listed financial equipment enterprises, and segmented research reports from third-party professional consulting institutions. Updates follow a quarterly regular schedule, with temporary reports added when major policies or market fluctuations occur. Document structures include structured parameter tables, market size analysis, upstream and downstream industrial chain data, policy interpretation and other modules. Fields include equipment model, rated power, annual production capacity, sales unit price and more. Corresponding units are mostly kW, units/year, ten thousand yuan/unit and similar formats.
Constraints Imposed on Document Parsing and Chunking
Documents from multiple sources use multiple formats including PDF, Excel and Word. Mixed-format parsing and chunking support is required to meet the batch upload needs of research reports from financial institutions. Large-volume research reports uploaded in batches require long-running parsing processes to prevent mid-task interruptions. For documents with mixed structured parameter tables and analytical text, chunking must retain the connection between parameters and their surrounding context, to avoid separating technical details from industry analysis. Special unit fields must be fully preserved during parsing, to prevent units from becoming detached from their corresponding parameters after chunking, which would impact accurate retrieval.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Specialized equipment research reports contain a large number of structured parameter tables, and complete extraction of cell content and format association is required |
UPLOAD_FILE_MAX_SIZE | 2000 MB | The file size of individual large-scale industry research report PDFs often exceeds 500 MB, so the upper limit needs to be relaxed to support large file submissions during batch uploads |
chunk_size | 800–1200 characters | Specialized equipment research reports contain both technical parameter details and analytical text. This length can retain the complete association between parameters and upstream and downstream analysis |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | The parsing and chunking process for large-volume research reports takes a long time, which avoids mid-task timeout interruptions |
table_chunk_merge_threshold | 300 characters | The single row and column data of specialized equipment parameter tables is relatively short, so adjacent table chunks need to be merged to retain complete parameter groups |
The parameter values provided on this page are common recommendations for establishing a starting point 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 Errors
- Phenomenon: After uploading an Excel-format specialized equipment parameter table, some fields are empty or units are lost after parsing. Cause: The
PARSE_TABLE_ENABLEconfiguration is not enabled, or the retention parsing rule for special unit fields is not activated. - Phenomenon: An upload failure prompt appears when uploading CSV or Excel files, or the table upload entry cannot be found when creating a file collection. Cause: The system has not enabled the table parsing module, or the file format is not set to a supported table type.
- Phenomenon: Vectorization takes too long after uploading a research report, and task progress stalls. Cause: The
chunk_sizeconfiguration is not adjusted, with an excessively short chunk length leading to a sharp increase in the number of chunks, or batch parsing queue optimization is not enabled.
How to Confirm Proper Configuration
- Upload a small specialized equipment research report that includes a parameter table, and check if the parsed text fully retains fields such as equipment model, rated power, unit price and their corresponding units.
- Upload a single file of conventional industry research report scale, confirm that the parsing task does not trigger a timeout error, and review the complete parsing process via the task log.
- Test different
chunk_sizevalues, and compare whether the chunked text includes both technical parameters and upstream and downstream analysis content, to avoid separating parameters from their context. - Upload batch table files, confirm that the cell content of all tables is fully extracted, with no missing fields or format confusion.
