What the Data for This Category Looks Like
Data for general equipment research reports mainly comes from broker industry research reports, public industry reports from relevant industry associations, and regular and interim announcements of listed companies. Update cycles are typically quarterly and semi-annual, with interim supplementary documents generated alongside events such as capacity adjustments and new product launches. Document structures usually include modules such as overall industry scale, capacity parameters for sub-categories, downstream application proportions, and revenue data of leading enterprises. Fields include equipment rated power, annual capacity, per-unit selling price, and more. Most units use standardized industrial measurement units such as kilowatts, ten thousand units, and ten thousand yuan.
Constraints on Document Parsing and Chunking
Significant format differences exist across data sources. Broker research reports are mostly multi-column PDFs with complex layouts. Association reports are primarily dense tables. Listed company announcements have fixed structures but scattered fields, which requires the parsing module to support format adaptation. Long documents account for a large proportion, and single quarterly research reports vary widely in length. It is recommended to determine settings based on local samples or actual testing. Chunking must avoid cutting across modules to prevent separation of core parameters and associated descriptions. Most parameter fields are bound to specific industrial units. Parsing must retain the corresponding relationship between values and units to avoid isolated values after splitting. Interim supplementary documents have no fixed templates, with random field arrangements. Adaptation to non-standard content structures is required to improve context recognition accuracy for chunking.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_SEGMENT_MAX_LENGTH | 800–1200 characters | Core parameters and industry scale paragraphs of general equipment research reports usually fall within this length range, avoiding loss of context association after splitting |
PARSE_KEEP_UNIT | Enabled | Must retain the binding relationship between units and values for parameters such as equipment rated power and annual capacity, preventing field distortion after parsing |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Single quarterly research report collection usually does not exceed 800 MB, reserving a reasonable upper limit to cover most upload scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large research report collections take a long time to parse, avoiding mid-process timeout interruptions of the parsing process |
RECALL_CHUNK_COUNT | Top 10 entries | General equipment research reports have many types of detailed parameters, so sufficient context fragments must be recalled to support accurate question answering |
SIMILARITY_THRESHOLD | 0.75 | Filter low-correlation non-core parameter fragments to improve the targeting of search results |
The parameter values provided on this page are common 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, and testing on local samples is recommended before finalizing.
Three Common Misconfigurations
- Phenomenon: After uploading a general equipment research report PDF, the system displays a successful upload but no parsing completion status prompt, and subsequent search tests return empty results. Cause: The
PARSE_AUTO_NOTIFYconfiguration is not enabled, and the parsing timeout period is set too short, causing large document parsing to be terminated before completion. - Phenomenon: After uploading some general equipment research report PDFs containing embedded tables, the parsed text fields are empty. Cause: The
PARSE_EXTRACT_TABLEconfiguration is not enabled, and the system fails to correctly extract core data such as capacity and parameters from tables. - Phenomenon: Parsed chunks are cut across modules, such as splitting "rated power" and subsequent "application scenarios" into different fragments. Cause:
PARSE_SEGMENT_MAX_LENGTHis set too small, and thePARSE_PRESERVE_HEADINGconfiguration is not enabled, causing the system to fail to recognize document heading levels for reasonable chunking.
How to Confirm Configurations Are Properly Set
- Upload a standard general equipment quarterly research report PDF, check whether the system's parsing status prompt is displayed normally, and confirm that related configurations take effect.
- Enter the search test interface, enter parameter query terms related to general equipment, check whether the returned results include the corresponding parameter values and units, and verify the accuracy of field parsing.
- Adjust the value of
PARSE_SEGMENT_MAX_LENGTH, compare chunking results under different settings, and confirm that module boundaries are not arbitrarily cut. - Upload multiple general equipment research reports of different formats, verify the consistency of parsing results for documents from different sources, and confirm that the configuration adapts to multi-scenario documents.
