What the data for this category looks like
Automated equipment research report data primarily comes from publicly available industry association materials, official technical documents from equipment manufacturers, segmented track research reports from securities research institutes, and industrial tracking reports from third-party consulting agencies. Updates are timed to align with industry event milestones, including quarterly tracking reports, special new product launch documents, and annual industry review materials. Most documents contain structured parameter tables, long-form technical descriptions, supply chain-related paragraphs, and some embed equipment photos and engineering case screenshots. Covered fields include rated load, operating speed, production efficiency, and floor space, with corresponding units such as newtons, revolutions per minute, pieces per hour, and square meters.
What constraints do these characteristics impose on the document parsing and chunking workflow
Automated equipment research reports have a high proportion of structured parameter tables, and parameters have strong correlations. Standard text chunking can easily split content that spans related parameters, so structured table information must be preserved. Document lengths vary widely; some annual review documents span hundreds of pages, so the parsing and chunking workflow must support long documents. Some documents embed images with parameter annotations, so OCR must extract technical parameters from images and bind them to corresponding text paragraphs. Dense professional parameters and units require the parsing process to retain the binding relationship between fields and units to avoid information loss.
How to Set Configurations
| Configuration Key | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Automated equipment research reports often contain multi-page long tables and dense technical paragraphs, with parsing time longer than general documents. The default value cannot cover the full parsing process |
maxChunkSize | 800–1200 characters | The parameter paragraphs and technical descriptions of automated equipment research reports are concentrated in this range, to avoid splitting text blocks with cross-parameter correlations |
chunkOverlap | 100–150 characters | Contextual connections between parameters and preceding/following descriptions must be retained, to avoid losing the binding relationship between parameters and units during retrieval |
ENABLE_TABLE_PARSE | Enabled | Automated equipment research reports have a high proportion of structured parameter tables. Retaining table structure can avoid incorrect parameter splitting |
PARSE_IMAGE_OCR_ENABLE | Enabled | Some research reports embed photos of equipment with parameter annotations. OCR recognition can extract technical parameters from images and bind them to corresponding text |
UPLOAD_FILE_MAX_SIZE | 500 MB | Some annual industry review documents have large single-file sizes, so the configuration must support large file upload and parsing requirements |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: File parsing tasks return timeout errors or status code 504 Gateway Timeout. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. The default value is insufficient to cover the parsing time of long tables and dense paragraphs in automated equipment research reports. - Symptom: Parsed chunked content loses the binding relationship between parameters and units, with some fields empty. Cause: The
ENABLE_TABLE_PARSEconfiguration is not enabled, or themaxChunkSizevalue is too small, causing structured parameter blocks to be split. - Symptom: Services deployed on version 4.9.0 cannot normally call the file parsing tool. Normal functionality is restored after switching to version 4.8.20 or the v1 marker image. Cause: The file parsing module in version 4.9.0 has a compatibility vulnerability with the format of automated equipment research reports. Roll back to a stable version or update the marker image to v0.2 or later.
How to Confirm Configurations Are Correctly Set
- Upload a typical automated equipment research report PDF, check the parsed text content, and confirm that structured parameter tables are fully retained, and parameters and units are not split.
- Check the parsing task logs, confirm that the
PARSE_FILE_TIMEOUT_SECONDSparameter takes effect, and the task is not interrupted within the preset time. - Test the chunked retrieval function, enter a query containing specific equipment parameters, and confirm that the returned chunks contain complete contextual associations of the parameters.
- Upload a document with a single file volume close to
UPLOAD_FILE_MAX_SIZE, and confirm that the upload and parsing processes do not report errors.
