What the data for this category looks like
Publishing industry research report data mainly comes from formal professional research and publishing institutions. The update cadence is divided into weekly, monthly, and quarterly updates based on the research cycle. Documents are mostly in PDF and DOCX formats, with a standard structure: preface abstract, table of contents, main body analysis, embedded structured tables and data charts, and appendix notes. Fields include the unique report number, full name of the publishing institution, release date, industry rating, and core business data. Units are mostly professional financial measurement units such as percentage, ten thousand yuan, hundred million yuan, etc.
What constraints these characteristics impose on the document parsing and chunking link
Wide-ranging report sources lead to significant format differences. Some documents contain embedded encrypted content or non-standard layouts, which increases the difficulty of parsing error tolerance. Long-form professional content requires chunking to retain contextual logic, and avoid splitting professional argument chains. Embedded structured tables and images must be fully extracted, otherwise core data will be lost. High-frequency batch upload requirements mean parsing configurations must adapt to high-concurrency scenarios, to avoid task timeouts or load overload.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600-900 seconds | Single long-form research reports contain a large amount of professional analysis and charts, and complex format parsing takes a long time. This value range avoids timeout interruptions for routine tasks |
maxChunkSize | 800-1200 characters | Research reports contain dense professional logic chains and terminology. Chunks that are too long will destroy argument coherence, while chunks that are too short will split professional terminology and associated data |
chunkOverlap | 150-200 characters | Progressive professional analysis exists between report chapters. Overlapping chunks retain cross-chapter contextual connections, and improve retrieval accuracy |
UPLOAD_FILE_MAX_SIZE | 500 MB | Adapts to the needs of single ultra-long research reports or batch uploads of multiple research reports, and avoids triggering upload restrictions due to oversized files |
PARSE_ENABLE_TABLE | Enabled | Research reports contain a large number of embedded structured data tables. Retaining table parsing ensures information integrity and readability during retrieval |
PARSE_IMAGE_OCR_ENABLE | Enabled | Some research reports embed core data charts in image form. OCR parsing extracts text and numerical information from these images |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common errors
- Phenomenon: After uploading a DOCX research report with embedded images, the parsing result returns the
Invalid image fileerror. Cause: ThePARSE_IMAGE_OCR_ENABLEconfiguration is not enabled, or the uploaded image format is outside the system's supported range. - Phenomenon: When batch parsing research reports, the log outputs
slow operation xxxxmsand the parsing task times out and fails. Cause: ThePARSE_FILE_TIMEOUT_SECONDSconfiguration value is too low, and does not adapt to the parsing time required for long research reports. - Phenomenon: Markdown-formatted research report tables are truncated after output and cannot display content completely. Cause: The
maxChunkSizeconfiguration value is too small, and table content is split into multiple chunks, losing the overall structure.
How to confirm the configuration is correct
- Upload a single typical-length research report, check if there are timeout errors in the parsing log, and adjust
PARSE_FILE_TIMEOUT_SECONDSto the value that allows the task to complete normally. - Parse a research report with embedded tables and images, check if the returned results fully retain the table structure and the text content extracted from images, and confirm the configuration status of
PARSE_ENABLE_TABLEandPARSE_IMAGE_OCR_ENABLE. - Retrieve the parsed research report content, verify that professional terms and data units are not split, and adjust the values of
maxChunkSizeandchunkOverlapto a range that maintains logical relevance. - Batch upload multiple research reports, check server load metrics, and adjust
UPLOAD_FILE_MAX_SIZEto a reasonable upper limit adapted to the current hardware configuration.
